Chapter 471: groundwater

"Small... girl, how did you come out?" Wu Qianru continued to ask.
"Ah, I don't know. I slept. I woke up and it was already in the dark. I have been digging, I have been digging, I have dug a long hole, and I walked to the ground. "The little girl thought about it and said."
The two listened secretly and shocked. Although some of the words expressed by the little girl were unsatisfactory, it is not difficult to see what happened to her in the event of the disaster.
After sleeping, it was estimated that the aftermath of the antimatter bomb was seriously stunned, and when I woke up, I was in the ground. There was no doubt that her body was buried when the magma was cooled.
If everything is true, then her seemingly delicate body, obviously has the power of inconspicuous, but whether it is the naive expression of the other side, or the scene buried in the ice layer, it clearly shows that the other party does not lie.
But no matter what, letting such a little girl fall in the snow, I can’t bear it.
Although bringing her to the city of hope may have some hidden dangers, but the strength of the other party is still in their understanding, but Luo Yuan, who has eliminated aliens in propaganda, is still worse.
The two looked at each other and seemed to be convinced that such a small monster would still give a headache to a big monster like Luo Yuan.
......
Soon, the little girls decided to follow them back to the city of hope without any prejudice.
The three people walked and talked, and gradually more and more information was revealed from the mouth of the little girl.
She has no name and no parents. Apart from a number that does not make sense, she has no identity information. Similarly, her brothers and sisters are the same as her. They are a group of super-powerful children. In the room, a unified education and training.
A little association, Lin Feiyan has already had some certain guesses in his mind, the other party should be a clone.
She is not surprised. The end of the world is undoubtedly a crazy era. When the standard of good and evil of ordinary people rises to the height of racial survival, there is no such thing as good and evil. It is more crazy and wicked than the clone, and she has vaguely heard it. It is a laboratory for studying human body and has a death indicator every month.
But these are too far from her, this is the first time she saw a real clone.
From the little girl's mouth, she did not hear anything dark, neither imaginary medicine, no injections, no slicing, but stricter militarized management.
"Right, how old are you?" Lin Feiyan asked curiously.
The little girl turned her head and thought about it: "Auntie, it may be nine months and twenty days! I have slept for too long in the underground, maybe I have to add a few more days."
"You are less than one year old?" Lin Feiyan couldn't help but listened. He almost forgot to walk. She looked at the body that was obviously five or six years old. It is hard to imagine that the other party was less than one year old. Moreover, in her previous conversations with the two, the little girl was articulate and logically clear, even if she was a child of five or six years old, she was already a small adult.
Normal human children are just learning the language when they are one year old!
Is this still human?
Wu Qianru was also a little surprised, and she couldn't believe it.
"I am a fast-growing group. Most of my younger siblings are slower." It seems that they noticed the two people's surprised expressions. The little girl bowed her head and said something awkwardly.
"The other people, are you as smart as you?" Lin Feiyan asked.
"No, some people are stupid. For example, the younger brother named A51621 only knows how to play every day. The teacher does not do the homework. As a result, even the primary school has not finished studying. I have already finished junior high school and started to study high school. The course is over." The little girl slightly lifted her chin, and some proudly said.
"That... you are really amazing!" Formerly Xuelin Feiyan was stunned, and some did not know what to say. Immediately, she turned to the topic and asked: "Right, you have been outside for so long, what to eat every day." what?"
"I haven't eaten for several months. Sometimes I am thirsty, I want to eat ice, the ice is too dirty, but I can't help myself. I finally swallowed it, I am so poor!" Little girl Saying, it seems to think of aggrieved, a mouthful, tears will fall.
The two women listened with heart and pity, and quickly comforted. Seeing that she had not eaten for several months, she did not want to be shocked. She simply did not rush to leave, put down her backpack and prepared to open the meal.
......
The mayor, this is the result of the geological survey of the underground city of Hope. "An engineer hurriedly handed a stack of documents to Luo Yuan.
Luo Yuan no expression, took the drawings, quickly flipped a few pages, suppressed the effort, Shen Sheng: "This is your report, how can it be so serious!"
The officials behind him and the leader of the waterworks factory were so scared that their faces were white and their hearts were tumultuous, and the atmosphere did not dare to breathe.
Do not blame him for being furious, it is really a big leak this time:
"It is only when the problem arises that geological research is started. What is the use of these people?" Luo Yuan walked back and forth, his face was gloomy.
Hope City, whether it is drinking water or domestic water, depends on groundwater. However, the geological structure shows that from the beginning of the two, the underground river, which is more than 300 meters deep underground, is already on the verge of depletion. A huge hollow.
According to estimates, for up to five days, Hope City will be cut off.
But this is not to make him the most angry, the most angry is that before this, everyone did not investigate the groundwater, until today, the bottom of the underground city, suddenly collapsed, and finally exposed the problem.
If there is no collapse, it will not work well. I hope that there will be a big riot in the city.
Looking at the relevant person in charge who was scared by his leaking breath, Luo Yuanshen took a deep breath and gradually calmed down in his heart. If he really wants to say it, he can’t blame these people. At the beginning, he took all the research of human beings. The personnel and most of the technicians were transferred to the spacecraft, which led to the serious lack of talents in the water bed. In addition, the lack of attention to the subjective city of Hope City has laid a hidden danger for everything today.

Talk about the reason?
Luo Yuan went to the collapsed place and said faintly.

We ignored the impact of the ice on groundwater, and the presence of ground ice impeded the water cycle, causing the precipitation to be unable to penetrate the ground and replenish the amount of groundwater.
The head of the factory explained with sweat.
Luo Yuan no expression, can not see his slightest emotions, so that the factory manager is even more frightened.
In fact, the problem of water is second. The biggest problem now is how to solve the impact of underground cavities on the entire dungeon.
This layer was originally idle, but after the disaster was transformed into an agricultural area, as the bottom of the underground building, the degree of solidity of the foundation, determines the stability of the entire dungeon, once the place is unstable, the entire dungeon may collapse .
Although the landslide area is not large, just a few hundred square meters, it has not had much impact on the stability of the overall structure of the underground city, but its appearance is already a sign, the cavity has been formed, the structure has been destroyed, even if it is no longer pumping, There is no guarantee that it will not continue to collapse.
Perhaps a small earthquake can crush the last straw of the camel and trigger a chain reaction.

How much water is stored in the factory?
Luo Yuan asked.

Normally available for three days.
The factory manager replied quickly.
Luo Yuan listened with a sigh of relief: "Stop pumping now!"
"Yes!" Hearing the mayor's intention, this matter is still the responsibility of him, and the factory manager suddenly screamed.
"In addition, I would like to ask, this underground hole, how are you going to solve it." Luo Yuan asked.

Pour the mixed soil, or hit a lot of piles!
one civil engineer suggested.
Secretary Cheng Guanghui reminded me: "The mayor, the cement inventory is not much, it is estimated that it is less than one hundred tons!"
Luo Yuan is also aware of this. In order to cope with the frequent earthquakes after the disaster, the underground city was reinforced. I hope that the city has built a lot of load-bearing columns, and the inventory of cement is as much as the flood discharge.
In fact, it is not just cement. Other types of reserve resources have already consumed almost. If Luo Yuan has already found a way out, human civilization may only be in the city of hope, and then slowly Withering.

If there is no cement, water can be used, and the presence of water can greatly support the geological structure.

Luo Yuan nodded. The reason why it collapsed now is the reason why the underground river is exhausted. It is also a way to replenish it with water. However, this matter will not be solved in a moment. He looked at the watch and said to Cheng Guanghui: The leaders of the cities will meet at four in the afternoon!"
"Okay, mayor, I will go first!" Cheng Guanghui said respectfully. Now that it has been more than three o'clock, the time has been somewhat rushed. He has to return to the office as soon as possible, and he will call the city leaders to inform him. The strong electromagnetic pulse caused by the anti-material bomb explosion has caused most of the communication equipment to be damaged. Nowadays, some old and easy-to-repair fixed telephones can be used.
Luo Yuan nodded and continued to inspect the waterworks. Seeing a huge cistern in the factory area, his face was slightly better.
Although the water resources have become extremely abundant after the nuclear winter, the thickness of the ice layer above the surface has reached tens of meters. If it is fully formed into water, it is enough to form a vast ocean.
However, it is quite difficult to extract these ice cubes. First of all, it is extremely hard. Under such extreme cold, the steel will become crunchy. The ordinary metal tools are useless and time-consuming. Secondly, even if the ice is mined, it cannot be directly consumed. One-third of the mass of the ice is solid impurities and there is also a large amount of electrolyte dissolved in water, which must undergo a series of complicated physical and chemical treatments.
And these undoubtedly take time.
There are now three days to buffer, which should be enough.
