Chapter 161 My friend, she doesn't allow anyone to destroy her!
　　After hearing Mu Qing's words, Mu's mother also asked.
　　Seeing everyone's nervousness, Mu Qing hurriedly said, "It's nothing, but a classmate may come over in a while." "
　　Is it a man or a woman?" Zhang Baolai is most interested in this, and it's been a long time , I never heard my daughter mention any classmate or friend.

　　Mu Qing's face is really full of black lines now, Zhang Dad really can't forget the matter of squeezing out Jun Zhao.
　　In fact, Mu Qing really wronged Zhang Baolai this time, not because he wanted to squeeze out Jun Zhao, but he is quite satisfied with Jun Zhao now.
　　The main reason is that their family has taken a lot of advantage by relying on their own family. If it is so wasteful, the resources of the initial investment will be wasted.
　　Zhang Baolai felt that since his daughter was a young man, it was not good to live like an old man every day. Little did they know that Mu Qing had already been in the end times for ten years, and she really didn't feel close to many of her friends.
　　As for this, I still felt that the relationship between the other party and myself was not enough before I agreed to them to come here, and I helped their family arrange a place to live.
　　"It's my best friend in high school." Mu Qing was very helpless, and had to get rid of Zhang Dad's petty thoughts.
　　"Girlfriend, if you come as a family, will you live in our house?" The person who is most worried is Grandma Mu. Apart from Mu Qing, she is the most clear about the situation in their family, and she is also a rare sober person in this family.
　　Sometimes when my mother said that a family is as old as a treasure, she was not talking about it. Sometimes, Grandma Mu's vision is really unique, and sometimes she can even complement Mu Qing.
　　"Of course not, what I want to say is this..." Mu Qing ate the last piece of ribs and continued after articulate, "If you come, just give them the room in our front yard."- _-! Thinking-_-
　　! Rabbit -_-! Net-_-! Let the family live in.
　　Today's people are not all good people. What Sheng Mi Qiu Dou Mi En said was not all lies. They couldn't look at others with prejudice, but they couldn't be defenseless either.
　　On the Jun's side, she was a little worried sometimes, let alone others. Seeing that the situation is getting worse day by day, although the supplies at home are very abundant, she has always been worried in her heart.
　　Mu Qing doesn't think there is any difficulty that he can't solve at present, even if he can't solve it, a bag of grain can solve it. One bag is not enough, two bags at most.
　　And what she lacks most now is food. It can be said that her rebirth gave her confidence beyond imagination.
　　"Well, so it's enough to live there. The tenants in our house are all okay, and there are no evil people."
　　For these tenants, they may not be so holy and kind, but they are not considered bad people. Maybe they would ask for something because the rest of the Mu family are talkative, and treat Mu Qing differently from the others, but they would never do anything out of the ordinary.
　　Especially, knowing that Zhen Wan and her family are friends, it will be even more impossible for them to do this. Doing this is completely thankless. Could it be that you bullied the landlord's friends, and you can expect others to treat you well?
　　Even Ao Jia, Mu Qing's cousin, was treated politely by these tenants. After all, they are somehow related, who are you?
　　In case the family reconciles in two days, wouldn't you be human on both sides?
　　"What about the other things?" Father Zhang thought about it, and decided to ask about his precious daughter's attitude. If it really matters, it's okay to go through the back door.
　　"Don't give me anything special. I just agreed to solve the housing problem." Mu Qing didn't say much about the rent. If they believed that the misers in his family would not want it, they wouldn't even pretend to refuse. Will not.
　　What they believe in is, what if they pretend to refuse and others really don't give it.
　　And if they didn't give it, they probably wouldn't ask for it. After all, they are their daughter's guests, and they are not good at making their own decisions.
　　As for this issue, Mu Qing did not mention it. What you see is whether the other party is conscious or not. After all, we haven't seen each other for many years. The changes in the end of the world are not a little change.
　　If the other party is difficult to get along with, then staying here is just a house. If it is a family that can get along with each other, then waiting for their mission to come back is naturally another way to get along.
　　"Okay, then we understand..." Grandma Mu said that people of the older generation like them can still grasp this well.
　　"It's fine for the family to know, and I'll deal with their affairs mainly when I come back." Mu Qing was worried, "If you ask anything, just push it to me." "Look at what your child said." Mu's mother was a
　　little Reluctantly, "Master of our family, do we still need you to go out and do things? You should think about safety outside."
　　Mu Qing watched the family's attention return to him, helpless, but still had to Go ahead and promise. "Don't worry, I don't have any problems this time."
　　The mission this time couldn't be better. There will be no weather that tortures the dead, and there will be no geological disasters that may occur at any time. All in all, this kind of mission is already a superior and easy mission compared to the two missions she set out before.
　　"You can't take it lightly. Those who drown will be able to swim." Zhang Baolai and the others are doing construction, and the worst thing they can't see is carelessness.
　　A lot of people died in their construction site in the past two years, and because they were temporary workers, they signed an agreement before going on the field, so they wouldn't get much money if something happened.
　　It is not without family members who come to make trouble, but many of them are caused by improper operation. Zhang Baolai can't get compensation from the public, so his job will not be guaranteed, and sometimes he will get some compensation from his own salary.
　　But this kind of family who has lost their pillars knows that the future will be difficult.
　　Mu's mother couldn't hear Zhang's father's words, so she slapped Zhang Baolai's arm directly, "What nonsense are you talking about, you can't die, hurry up, pee, pee, pee!
　　" Now that I heard what my daughter-in-law said, I realized that I was really wrong. How could I say such frustrating words when my daughter was about to go out.
　　"Bah, bah, bah!" Zhang Baolai hurriedly spit out his bad luck a few times.
　　"This is what it looks like..." Mu's mother was relieved when she heard that Zhang's father didn't talk nonsense.
　　Looking at the relationship between the family members, the corners of Mu Qing's mouth are slightly raised, this is the life she has always dreamed of, and she does not allow anyone to destroy it!

Chapter 162 Departure is even more so in the last days...
　　After staying at home for another two days, there is still no news from Zhen Wan. Instead, Mu Qing sent a message before leaving home.
　　The general meaning is that she will go out to work in two days, and the house here has been arranged. Sent them the address.
　　If they are willing to come, they can come directly, and their family members will help them arrange the living.
　　As for more, Mu Qing didn't say anything. Individuals have their own destiny, she can't pay too much for each other.
　　So, without waiting for the other party to reply, she followed Dad Zhang and left to the station to go into the mountain.
　　Most of these people who set off are familiar faces, and there are some new faces. But generally speaking, the team this time is not as large as the team last time. Mu Qing also understood that this had something to do with the difficulty of this task.
　　They had so many people last time because the sky was high and the emperor was far away, and they were considered isolated and helpless in the past. But now it is near the base, naturally

There is no need to bring a large team of people.
　　She didn't believe that Sun Xiaojing would really have no way to contact the base. They are usually blocked by mobile phone communication because the base stations in various places are severely damaged. But the people in the base, they are high-tech talents, and their contact has been cut off. Mu Qing doesn't believe it.
　　The fact is also that Sun Xiaojing has a way to contact the base. But it's really not as convenient as Mu Qing thought, at most it's the kind of signal. After all, the damage of the base station is not something they can solve out of thin air.
　　It cannot be said that because they are all scientific researchers, they can communicate directly with brain waves.
　　Having not seen Mu Qing for several months, Sun Xiaojing felt very kind when she saw that she was still in the same outdoor off-road attire.
　　In the team she leads, Mu Qing can be said to be her favorite player. In this troubled world, who wouldn't like a person who can share delicious food with you at any time?
　　Even if what Mu Qing shared was ordinary things, Sun Xiaojing would not like it so much, so she couldn't refuse most of the time. But she really couldn't refuse what Mu Qing offered.
　　"Qingqing is here!" Sun Xiaojing saw Mu Qing's father for the first time. Because of the bad weather, they all set off in a hurry. Everyone was wearing raincoats because of the rain, so it was not easy to meet. , but this time I saw Mu Qing's family members.
　　Watching Mu Qing get off the electric car, Sun Xiaojing smiled. I thought to myself that the current conditions of Mu Qing's family are still good, otherwise it would be impossible to still drive.
　　There are not many people who can drive now, and there is no doubt that they are still driving now because they have mines at home. Sun Xiaojing silently raised the situation in Mu Qing's family to a higher level.
　　"Haha, this is Qingqing's father."
　　Zhang Baolai is a simple and honest person, and if he talked to senior intellectuals like Sun Xiaojing before the end of the world, he would definitely be nervous. But now, after two years of tempering, he behaved in a moderate manner.
　　"Well, our Qingqing will trouble you."
　　"Don't bother, don't bother, I just took advantage of Qingqing." Sun Xiaojing said that she likes Mu Qing as a friend very much, and it doesn't hurt to have more such good friends.
　　Zhang Baolai met her daughter's colleagues and was relieved to see that they got along very well.
　　Everyone didn't exchange too many pleasantries, they just chatted politely for a while and then left. After Mu Qing got on the bus and left, Zhang Baolai also kept watching from a distance.
　　After getting in the car, Sun Xiaojing sat with Mu Qing as usual.
　　The two of them had a conversation about their life some time ago, and it was only then that Mu Qing found out. It turned out that Sun Xiaojing was an orphan, and she was the type where the whole family was full and the whole family was not hungry.
　　The government had always given her warmth and raised her up. Afterwards, she is determined to serve the country!
　　But in the society before the end of the world, there is really no shortage of little people like her. But now, with her value, she suddenly became alive like a piece of land that had been dry for a long time received rain.
　　Mu Qing didn't expect that Sun Xiaojing, who looked majestic and outgoing, was actually an orphan, but it was somewhat understandable when she thought of her desperate state of being a third mother.
　　If there is a family member, as long as it is not that kind of weird top quality, I am afraid that they will not allow their daughter to work like this.
　　She knew that as long as Sun Xiaojing was able to go to the mission, she would follow it personally. Even if she didn't follow her personally, she still had to do everything she could.
　　It can be said that she has been working for the past two years and has hardly ever rested.
　　Mu Qing didn't say much about his family. Sun Xiaojing is also a sensible person, and she can see Mu Qing's refusal.
　　For this situation, she was really not angry at all. Sometimes, she really understands that many people don't want to talk about the situation at home.
　　When she talked about her family to Mu Qing this time, she saw Mu Qing's father coming to see her off, so she exclaimed that it's nice to have a father, which made Mu Qing catch up and ask.
　　And she has always been reluctant to take the initiative to talk about the family, but there is no taboo. On the contrary, Mu Qing felt a little embarrassed to ask this.
　　"Sister Xiaojing, if you get bored in the future, you can ask me to go out to play together..." Mu Qing didn't invite Sun Xiaojing to her home, what a joke, she doesn't worry about others coming to her home, even good friends.
　　Especially in the later stages, she did not prepare so well to make a wedding dress for others.
　　"Haha, then I will remember. If I am bored and ask you out in the future, you are not allowed to refuse..." Sun Xiaojing likes Mu Qing very much.

　　"How dare I refuse, you are my big boss..." Mu Qing shook his head with a smile, and the two of them had a pleasant conversation.
　　"This time the task is relatively easy, I reserved it for you." Sun Xiaojing smiled, "I know you don't care about the rewards for doing the task, but this time there are not many rewards for the task.
　　" Those who care about rewards are all novices. It can be said that, except for Sun Xiaojing's treatment, which is higher, the treatment of others is average.
　　"Haha, don't you know me yet?" Mu Qing smiled, then tidied up her clothes, watched the car leave, and put on her seat belt.
　　"Of course I brought you here because I know you." Sun Xiaojing also smiled, feeling more and more that Mu Qing could be a man.
　　She is a straight person, she will say what she has, and she doesn't like to beat around the bush. Mu Qing's personality suits her very well.
　　The two of them didn't say anything more about this mission, they closed their eyes and rested after the car drove. Although the task this time is not dangerous and the fatigue index is very low, but those of them who often run in the wild know—never underestimate nature.
　　They always remain in awe of the power of nature, especially in the 　　last
days

...
The place I came from was not too far from the base, and I even drove towards the base at the beginning.
　　The vehicle did not let them down until the distance was about halfway. After everyone packed their luggage, they slowly entered the mountain along the valley path between the two peaks.
　　Everyone silently prayed in their hearts that they could find a suitable new water source this time, otherwise they might have to stay in the mountains for a while. But everyone also understands that Sun Xiaojing never fights uncertain battles, and she will not take risks when things are uncertain.
　　So although everyone is a little worried, they are very confident in Sun Xiaojing.
　　After getting off the car, Mu Qing automatically moved away from Sun Xiaojing. Who let people be surrounded by professionals all of a sudden.
　　Although Mu Qing has learned some geological knowledge during this period, it is still not enough for these people, and he is still a layman in their eyes.
　　After determining the general direction of the water source on the map, the leader, Sun Xiaojing, greeted everyone and headed towards the mountains.
　　This time, they not only need to find the water source, but also need to find a relatively smooth and easy road for construction. Otherwise, the water source will be available by then, but the construction cost is too high.
　　The water on the ground is now seriously polluted for various reasons. Moreover, although the temperature has dropped, the temperature of more than 30 degrees still makes the water on the ground evaporate extremely quickly.
　　Now everyone doesn't think there is any problem, but they can feel the drastic changes in the climate, and when they think of the prehistoric disasters they have learned in textbooks, Sun Xiaojing can't calm down.
　　Sometimes ignorance really is bliss. This time they did not take the shortest route, but found a gentle and easy-to-construct road.
　　Although there are some detours, but this way there is no need to find another route. Otherwise, if you don't look at anything and walk straight forward, it will be a hassle to find your way when you come back.
　　At that time, everyone was eager to return home, and I'm afraid they didn't have the mood and energy anymore.
　　Time passed quickly, according to the GPS positioning and satellite map display, it should be here soon.
　　However, it was getting late at this time. So Sun Xiaojing called everyone to start camping on the spot, rest for a night, and search the neighborhood carefully after getting up tomorrow morning.
　　The current night is especially dark, almost invisible. But everyone around the bonfire was not so depressed.
　　The current night is much hotter than before the end of the world. One is because the temperature is already high, and the other is because there is a lot of volcanic ash in the atmosphere, so the insulation effect on the ground is stronger. The temperature at night is naturally higher than before the end of the world. some.
　　In the later period, when the current heat of the earth is consumed, a new ice age will usher in. One is because the earth has already entered an ice age, and the other is because the volcanic ash in the atmosphere weakens the incoming sunlight, making the already small amount of heat even worse.
　　"Qingqing, when do you think this kind of life is the end?!" Sun Xiaojing understands what the lack of water will bring, and no one can see that kind of situation.
　　"I don't know." Mu Qing replied seriously and sincerely, "We can only take one step at a time." "I just
　　like your ability to not speak..." Sun Xiaojing looked at Mu Qing, suddenly choked up A laugh broke out, which made Mu Qing very helpless, "Shouldn't you comfort me at this time?"
　　Mu Qing was taken aback by this sentence, she seemed to have lost the ability to comfort others. Because after going through such a dark decade, everyone has gotten used to not comforting others.
　　Because there is almost no hope for everyone. If you comfort others, you may make them even more desperate.
　　"Yeah, it's because I'm sober enough..." Mu Qing picked up a piece of beef jerky and ate it, then handed another one to Sun Xiaojing. His immediate boss had to please him.
　　"My God, is your family still so rich in supplies?" Sun Xiaojing began to be a little curious about Mu Qing's family. Now, someone who can easily produce beef jerky and is willing to give it away is definitely a wealthy family.
　　"Haha, it's just that there was a lot of money before." Mu Qing didn't want to be too prominent, but he would never be the kind of person who would be too timid to do anything because he was afraid of trouble.
　　In her life, all she wanted to do was to be able to do whatever she wanted.
　　"That's enough to make people enviable." Sun Xiaojing touched the beef jerky in her hand, "When will we all be able to live the life we used to?
　　" It’s too wasteful to come here?” Mu Qing is right, the past hundred years of human society’s development for Su should be regarded as the most abundant era in the history of human beings.
　　However, there is a cause in the world and there must be an effect. Sometimes you don't know what the cause you sow will bear.
　　"You're right to say that, sometimes the cycle of cause and effect is so cruel." Sun Xiaojing was a little silent, and the black beef jerky in her hand was never eaten.
　　She didn't think about saving it up. One reason was that she didn't lack food, and those who fed the whole family by themselves were more chic. Another one was given by Mu Qing, she should eat it because of politeness.
　　However, when Sun Xiaojing thought about the future, she couldn't whet her appetite.
　　Sometimes Mu Qing really admires Sun Xiaojing, she is really serving the motherland, she is a great person. It's not that great people can be said to be great, some ordinary people can also have a great spirit.
　　Mu Qing never wanted to be a great person, she just wanted to be an ordinary person who lived for herself. Forgive her selfishness, she cannot have the same noble feelings as Sun Xiaojing.
　　"Sister, don't think about it. Life and death depend on fate and wealth. I never think about things that are too long ago. People

Live in the moment, seize the day and night is enough. "
　　Haha, it turned out that I was stunned. " "Sun Xiaojing laughed when she heard Mu Qing's words, and she didn't know where she thought.
　　In fact, where did she think, what Sun Xiaojing thought was the superficial meaning. She is thinking so much and worrying so much, but it is completely useless. It is better to be more sure. Let's do some practical things now.
　　"Then sister, you should rest early..." Mu Qing stood up from the ground, patted the dirt on his body, "There is still a big task tomorrow, but we can't do without you, let's hurry up go rest. "
　　"Okay, rest." "Sun Xiaojing also stood up with Mu Qing's extended hand, and the two returned to their tents.
　　This was the first night in the wild, and everyone's hearts were not particularly tired, so they rested soon. The fatigue from the first day disappeared when we got up early in the morning.
　　The next morning, after eating the rice porridge and white steamed buns made by the logistics, we started to head towards the mountain with full energy. However,
　　because it was confirmed that After knowing the general direction, everyone did not go far, but looked for water sources in this area. Or looking for the entrance to the underground cave.
　　Finally, at the foot of a bush-covered hillside, everyone found a cave.

Chapter 164 Underground River Causality
　　After seeing the entrance of the cave, everyone was overjoyed. This time the task was too smooth, and it was the smoothest task since they started working. It was only the afternoon of the second day after entering the mountain
　　. They found the goal of the mission, no matter whether it goes well or not, it doesn't affect their good mood.
　　This time, Sun Xiaojing searched for very detailed information, and it may be because the underground river is around the base. Ask The local people around know a lot of information.
　　This underground underground river, the locals call it the Diedong River, is named after the complex underground river system inside. The locals dare not enter easily. Get lost in it and it's easy to get out.
　　And this underground river is said to have never stopped flowing. Sometimes when there is a severe drought, they will fetch water to drink from here, and even people from hundreds of miles away will come to fetch water.
　　Sun Xiaojing came here only after hearing such rumors. It is true that underground rivers generally do not dry up and can serve as a stable water source.
　　However, even with a stable water source, she still decided to report to the leader when she went back, and must strictly formulate water-saving policies.
　　This is what she thought of when she heard Mu Qing's theory of causality last night, whether human beings have taken too much from nature, so this disaster is the earth's revenge?
　　The extra Sun Xiaojing didn't have time to think about it, so everyone stood at the entrance of the cave and looked out.
　　At this time, the view from their current angle is very good. They stand here are condescending, steep terrain.
　　Mu Qing observed the surroundings carefully. The back of this mountain is a sharp peak like a knife, which is easy to defend but difficult to attack.
　　Before she came, she saw the Diedong River on the work document and thought it was very familiar, so she asked Grandma Mu. According to them, they went here to fetch water during the severe drought in the past six or so years.
　　Mu Qing was surprised when he heard it. And I also heard that it is said that this is the place where Zhang Xianzhong hid his soldiers. At this moment in front of the cave entrance, Mu Qing also felt that the rumor might be true, because it can still be vaguely seen that this cave entrance was once a fort.
　　If it was before, everyone might still discuss it, but this time, I don't know if it was because the task was urgent, or everyone was thinking about home, so they didn't say much, but prepared to leave with a sullen head.
　　Because the terrain is very steep, it took them a lot of effort to come up.
　　After entering, everyone found that there was a part of the wall-like structure at the entrance of the cave. Mu Qing thought, perhaps this place was really built by the ancients for defense when they lived here.
　　During Sun Xiaojing's visit to the locals, she knew that the local villagers had passed through the cave by land, but they knew almost nothing about the underground river system on the opposite side. Therefore, their task this time was actually not as easy as they thought.
　　At least, it is not easy to find out this underground river. Fortunately, the people here are all professional geologists, so it is not very difficult to shuttle through this kind of cave, this is their instinct in their bones.
　　After entering, everyone found that the entrance of the cave was very large and square, with the height of five people in total, and the width of six or seven people with open arms. Generally speaking, the whole is still a square.
　　As soon as everyone entered the cave, they found that the entrance of the cave was straight, and there were grooves on the walls on both sides, which were about on top of people's heads. The grooves resemble the way a small airplane strays into a hole and its wings carve the walls of the hole.

　　These traces are obviously man-made traces, and definitely not naturally formed by nature.
　　Afterwards, Mu Qing found some thorn-like structures on the top of the cave, which should be formed by water dripping down from the top of the cave.
　　The bottom of the tunnel is blue-green, but quickly turns an earthy color.
　　Walking along the entrance of the cave, the roof of the cave gets lower and lower, and the cross section of the cave has changed from a square shape at the beginning to a flat cave with a height of only one and a half people.
　　After about ten minutes, there was a hole in front of it, but it was separated by a stone pillar in the middle, and a light appeared in the hole.
　　It is not difficult to see that this place seems to be traces of previous people's life.
　　After everyone took a closer look, they found that this place should have been an observation deck before. There is also a cave on the slope opposite the observation deck, only a few meters away.
　　Mu Qing thought of the legend that Grandma Mu and the others told her. It is said that Zhang Xianzhong was stationed here at that time. Now it seems that this legend is not nonsense.
　　From their point of view, there are a total of three side openings here. ◎Thinking◎Rabbit◎Network◎Documents◎Share◎With◎Online◎Online◎Reading◎
　　A large main entrance, on the upper left of the main entrance, there is an auxiliary entrance close to it, on the far side There is also a small hole. If you look closely, you can actually see that these three holes are actually connected.
　　Mu Qing doesn't know what this thing is for, but one can guess that it should be considered a fortification!
　　After walking for a while, everyone was pleasantly surprised to find that from a distance, there was a lake in the middle of the front, not too far away from us. So they quickened their pace and headed towards the underground lake.
　　When I walked in, I found that the lake was blue as a whole.
　　The terrain here is sunken towards the mountains, and you can see that the mountains on both sides are close together, showing a canine tooth gap, which is an excellent place for defense.
　　Mu Qing thought, sure enough, what grandma and the others said was quite sensible. I heard from grandma and grandpa that Zhang Xianzhong once set up many forts at the entrance of the cave.
　　This is probably the guess made by the people who came here to carry water when they saw these things, and it has been passed down to the present. As for whether it is true or not, there is no way of knowing, and it has nothing to do with them anyway.
　　I thought that the older generation used to carry water here to live, and now my group is here to explore the source of water. This is a bit like a reincarnation of the years, which makes people feel very interesting.
　　After a little inspection of the water quality of the lake, samples were taken back to the laboratory for detailed testing, so everyone did not stay longer, but continued to move forward.
　　After walking for a while, I found that there was a small hole ahead, and I needed to crawl forward. Relying on the spiritual principle that if the mountain does not come, everyone will crawl through the narrow cave here.
　　After passing through, it was found that there were many small balls on the ground of the tunnel. 　　Sun Xiaojing was also in a mood at this time, so she explained to Mu Qing
　　, "We geological people call these small bamboos holes, but some villagers may call them holes."
I feel a little funny. The two of them just discussed the environment here, and Sun Xiaojing also consciously gave Mu Qing a lesson so that she would not be out of place in the geological team.
　　She also sent study materials to Mu Qing before. I used to think that there was not much time to read this learning material. After all, whether it is printing or using a computer to read it is a luxury.
　　The former is unable to find the printer, paper and ink, while the latter is lack of power. However, seeing that Ao Muqing is still a good meal, she knows that she is a bit subjective.
　　"You still have to take a closer look at the information I sent you and study."
　　Sun Xiaojing doesn't think that people who can get beef jerky will not be able to afford electricity.
　　You know, in such a hot day, if there is no refrigerator, it is impossible for this beef jerky to be stored for such a long time.
　　In fact, if Mu Qing knew what Sun Xiaojing was thinking, he would still feel that she was making assumptions. Because her current beef jerky is really not from two years ago, but beef jerky made from newly slaughtered cows.
　　What's more, the things in their house can't be put in the refrigerator. Otherwise, how could a refrigerator store all the beef jerky she would eat for two years.
　　However, Mu Qing didn't say anything. She also carefully read the information Sun Xiaojing sent before, at least now she is no longer as ignorant as before when she entered here.
　　In fact, last year, when they were on a mission, she could often know something. But this time, she asked others to explain less, and she could know more by herself.
　　"Okay, I got it, sister, don't worry..."
　　The two of them didn't say anything more, they just walked forward with the large group. Many underground landscapes are unique, and they are absolutely invisible in normal times.
　　This time, Mu Qing took advantage of it, and just happened to find a place where he could check how his study results during this period of time were.
　　Moreover, the task this time is still very easy. According to her observation, they will be able to go out and go home in at most three days.
　　And this is not considered a deep mountain, they arrived in one day when they came. When the task is over, it is estimated that one day can go back.
　　This is undoubtedly a very easy task, especially for someone like her whose family is close. Mu Qing will be home within an hour after getting off the car.
　　Everyone walked forward and found that there was an area of stalactites in front of them. The largest one stretched from the top of the cave to the bottom of the cave. It was as thick as four or five people hugging each other. The texture creates an atmosphere of an underground heaven in the cave.
　　She thought of the stalactites that she saw when she went to someone's house, and felt it was a pity. The locals think these stones are beautiful, and because they don't know the law very well, they sometimes knock these stones off and move them to their homes.
　　As everyone knows, each of these stones took tens of thousands of years to form, and the loss of one is a great loss. Before the end of the world, it would be illegal to destroy stalactites.
　　After passing through the stalactite forest, everyone entered a tunnel.
　　Walking in this tunnel, everyone seems to feel that they are walking in it after hollowing out the keel. In fact, this tunnel is very strange, straight forward, and the stone wall of the cave is full of potholes, showing bone white under the illumination of searchlights.

Chapter 165 Consummation Diedong River is like this
　　It is not too uncomfortable for everyone to walk in the cold underground cave, at least the temperature makes people feel very comfortable. Compared with the sultry environment of more than 30 degrees outside, this underground is undoubtedly very suitable for human survival now.
　　If Mu Qing knew what everyone was thinking, he might laugh out loud. This underground is not suitable for human survival only now. After the weather becomes extremely cold, this underground is also extremely suitable for human survival.
　　After all, as we all know, if it is underground, as long as it is well protected from moisture and ventilated. So it is undoubtedly warm in winter and cool in summer. Now the underground is cool, but when it gets colder, the underground will be warmer than the outside world.
　　In the previous life, those who could live underground were civil servants. and

People who live on the ground either have the right to be able to afford the cost of gas heating, or they are poor. In the end either you have to work on the ground.
　　There are also some people who just don't get the places to go underground. After all, the underground space is also limited, and it is impossible for everyone to live there.
　　Mu Qing didn't think too much about it, what she was doing now was to observe her surroundings carefully and check her own learning results.
　　They walked in a group, and after a while, the tunnel changed from a keel-like shape to a strange shape.
　　Mu Qing observed that the environment here is against the background of the lighting, looking into the depths of the cave, it seems to be the Milky Way in reverse color, which is divided into upper and lower layers.
　　The upper cave walls still retain the same bone-white color as before, while the lower levels appear to be more earthy in color, but are actually rock.
　　The entire tunnel seems to be buckled to the bottom of the cave like the top of the cave to a cover, but the tunnel is formed due to unevenness.
　　Near the end of the tunnel, there is a stalactite hanging from the top of the cave, pointing a sharp blade straight to the bottom of the cave, almost dividing the tunnel in two, and it looks like a human throat from a distance.
　　After walking to the end of the tunnel, there is a small cliff at the entrance of the tunnel. It is said to be a cliff but it is only a few meters high. They finally descended with ropes. It's not too difficult.
　　After coming down, here is a step.
　　The surface of the steps is dark yellow, and there is a certain amount of accumulated water on each step surface, and it flows down step by step. The whole looks like a terraced field.
　　There is a loud sound of running water, but the front of the "terrace" steps becomes very steep. Going down from here is very dangerous, not only because of the steepness, but also because the ground here is also particularly slippery.
　　If one accidentally falls, it is easy to break a bone. It is undoubtedly difficult to break a bone at this time, at least it will be difficult for them to go back.
　　And it's not easy to heal after going back.
　　So, in the end, they had no choice but to explore from the edges extending from both sides, and found that there was a dark river flowing vertically and horizontally through the "terraced fields".
　　The yellow part is travertine, and the yellow is actually just attached to the bedrock.
　　Because the "terraces" are steep, they can only descend along the cloth rope. The travertine part extends along the water flow, and we can see the bedrock showing a purple-red color in the travertine gap.
　　Wading the dark river, upstream. The current is fast and the water temperature is very low. They must find the shore quickly. Walking in this kind of water is undoubtedly dangerous, but fortunately, there is no need to worry about the sudden rise of water when it rains outside, let them drown.
　　Everyone on their last expedition felt that their luck was simply good, as if they were the chosen ones. He was not drowned unexpectedly, but it was raining heavily outside at that time.
　　Fortunately, there is a small highland not long after the advance, and part of the water flows down from the groove of this small highland. After some effort, we climbed up from the bank of the plateau.
　　After walking to the high ground, the water flow changed from waist height to calf height, and the flow speed became very slow.
　　This is a large space, and there are two yellow lines at high places on both sides, which are the water level lines. In other words, when the water is at its highest during the flood season, their position is already five or six meters underwater.
　　Fortunately, we came here during the dry season, otherwise they might have finished exploring before the travertine terraces.
　　Another calcified terraced field appeared ahead.
　　Inside the calcification are small pools, each about the size of a human. Surprisingly, the water in these pools is warm and can be around thirty degrees. This is nothing short of boon in the depths of the cave.
　　After climbing up the travertine terraces, everyone present was shocked by the sight in front of them.
　　There are red stones all over the place, shining with oil, and the average size is as big as a person can barely hold in his arms. This is Nanhong rough stone, and its purity is very high, there is almost no dust and impurities on the rough stone, and the red color of the whole rough stone is very bright.
　　After walking through the southern red land, another pile of stalactites appeared. One of them rises from the ground, and when the top is illuminated by a probe, it will glow a faint ice blue.
　　There is also a large stone hanging from the wall of the cave. The whole is composed of black body, yellow travertine and red attachments, just like a landscape painting.
　　Entering a rapid water area, the rock wall is narrow, and white flowers appear in the rapid water flow. In fact, this kind of rapids with white flowers is relatively safe, because it looks like there is a lot of water, but in fact it is basically air, which does not produce a lot of impact.
　　Here, they have to be careful not to get their feet stuck in the bottom of the water. If they get stuck, there is no way to bend down to get out of the water, and it is even difficult to observe the situation.
　　Fortunately, after advancing carefully, all of them were out of danger, found a flat open space and set up camp for the night.
　　The cave at night is not very comfortable because it is relatively humid inside. If you want to live in the future, moisture proof still needs to be done.
　　But no matter how well the moisture-proof is done, those who live underground will basically suffer from rheumatism in the future. She has seen the kind of disease that deforms the bones.

　　Therefore, those who can afford the cost of heating will not live in caves. That seemed to them a regression. They weren't cavemen long ago.
　　At night, the cave gradually quieted down without the sound of their traveling together, and everyone fell asleep easily after a hard day's work.
　　The next day, everyone got up early in the morning and continued on their way.
　　Because they are going to advance from relatively icy water this time, the speed must be fast, otherwise it is easy to lose temperature in this kind of water.
　　Fortunately, although the place ahead is flooded, there is a step at the bottom of the water. When we climbed to the step, the water depth is only ankle high.
　　In the end, everyone climbed up from the water to a high ground with travertine, and everyone was surprised to find that there were many bone residues on the ground here, which should have been lived here a long time ago.
　　They even found the blackened marks on the ground left by the fire, and there were many bones scattered around it, which looked like bats.
　　Mu Qing didn't pick up these bones, but squatted down to observe them, thinking to himself, it seems that the legend that Zhang Xianzhong was stationed here back then is very likely to be true.
　　The traces here are clearly that someone has lived here for a long time. This also shows that the basement here can definitely live. However, after all, living for a long time will be bad for the body.
　　In fact, even on the current ground, because of the lack of sunlight, everyone is not living very healthy. It's just that Mu Qing bought a lot of lights back then, which can give the family light. ↙Si↙Tu↙↙Online↙Reading↙↙Finally
　　, they walked through the calcified ground, then waded through a pass, and what they saw was a three-story corridor.
　　In their eyes, this can already be regarded as a magnificent building.
　　At this time, the fast-footed team members had already landed and climbed to the corridor on the second floor, so Mu Qing could only speed up his pace to follow.
　　After arriving at the corridor on the third floor and walking forward, the scene that followed was something Mu Qing had never seen in his life.
　　This scene is very similar to the Yadan landform, but it is completely opposite.
　　The Yardang landform is formed by wind erosion, while the scene here is formed by water erosion and hangs upside down on the top of the cave. Although it is not very high, you can touch these raised rocks with your hands.
　　The scene formed by the stones here seems to be anti-gravity. Only a small part of a large triangular pyramid-shaped rock is connected to the cave wall, and most of it is suspended in the air. Besides, there are many strange scenes, which are really shocking.
　　The travertine is attached to the rock at the top, and the shape is very similar to the flow of water pouring into a stream and then flowing down from the top stone tip of the cave. If it is changed to green, it can be described as "green and dripping".
　　It's a pity that this is not their destination, and it's not too unusual for old geologists like Sun Xiaojing. Because of the pressure in her heart, Sun Xiaojing traveled much faster this time.
　　Many times, when I saw some rare things, I left without even raising my eyes.
　　Without staying too long, everyone passed through several levels of secret passages one after another. In each level, the roof of the cave is almost completely pressed against the water surface, leaving only a small part for probes.
　　After going through the hidden levels just now, they came to a hidden space.
　　It looks like a tomb here, with a raised part in the middle, but unfortunately more than half of it has been obviously dug out.
　　Mu Qing was bored thinking about the legend about Zhang Xianzhong's treasure, maybe this is Zhang Xianzhong's tomb? I just don’t know if archaeologists will have the energy to maintain it if it is found now.
　　Of course, if it was so easy to find, how could it be Mu Qing's turn. Of course it can't be here.
　　Mu Qing looked forward, although there was still a pass in front, but because it was too closed, people like them with heavy armor on their backs obviously couldn't pass through. So naturally, he couldn't move forward, so he could only return to find other tunnels.
　　Along the way, they found another water area that was warm, and they could just take a rest in it to recover their strength and body temperature.
　　Passing by the hot spring area, everyone climbed ashore, and there was an enclosed area similar to a hearth, where a steady stream of warm water flowed from a gap in the hearth, which seemed to be built by the ancients to take warm water. thing.
　　This makes it even more certain that there must have been people who lived here for a long time before. This underground river is by no means unexplored. There are probably quite a few people who lived here before.
　　Finally, everyone saw a deep gully on the top of the cave, like a dragon flying on the top of the cave.
　　Looking ahead, they found a little bit of faint light, just like the foggy sky outside. They walked over and took a look, thinking that this should be the entrance of the cave.
　　It was only after I came out that I realized the reason for the name here:
　　the mountain walls here are full of caves, large and small, and there is a blue river below the mountain, such as the Diedong River.
　　Sun Xiaojing ordered at the entrance of the cave to rest here for a day today. After the camp was set up, she took a few assistants and got into the tent with a lot of materials, not knowing what to say.
