Epoch of Twilight

"Little... girl, how did you get out?" Wu Qianru continued to ask tentatively.

"Ah, I don't know, I fell asleep, and when I woke up, I was already in the dark underground. I kept digging, and I dug a hole for a long, long time before I reached the ground. "The little girl turned her head and thought for a while, then said.

The two were secretly shocked. Although the little girl's words were not expressive, it was not difficult to see what she had experienced when the disaster happened.

After sleeping, she was probably seriously injured by the aftermath of the antimatter bomb and fell into a coma. When she woke up, she was underground. There is no doubt that her body was buried when the magma cooled.

If everything is true, then her seemingly delicate body obviously possesses unimaginable power. However, whether it is the other party's innocent expression or the scene of being buried in the ice before, it clearly shows that the other party is not lying.

But no matter what, it is unbearable to let such a little girl in the ice and snow.

Although there may be some hidden dangers in bringing her to Hope City, the opponent's strength is still within the scope of their understanding, but compared to Luo Yuan who wiped out all the aliens in the propaganda, it is still worse than Luo Yuan.

The two looked at each other, and seemed to understand that such a small monster should be handed over to a big monster like Luo Yuan to have a headache.

...

Soon, the little girl unsuspectingly decided to follow them back to Hope City.

The three chatted while walking, and gradually more and more information was revealed from the little girl's mouth.

She has no name, no parents, and no identity information except for a meaningless number. Similarly, the brothers and sisters in her mouth are also in the same situation as her. In the room, conduct unified education and training.

After a little association, Lin Feiyan already had some definite guesses in her heart, that the other party should be a clone.

She was not surprised at all. 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. She has also vaguely heard of experiments that are more crazy and evil than cloning. It is some laboratories that study the human body, and there is a death indicator every month.

But these are too far away from her, this is the first time she has seen a real clone.

From the little girl's mouth, she didn't hear anything dark. There was no medicine, no injections, and no slices as imagined. It was just stricter military management.

"By the way, how old are you?" Lin Feiyan asked curiously at this moment.

The little girl tilted her head and thought for a while: "Auntie, it may be nine months and twenty days! I slept too long during the underground period, maybe a few more days will be added."

"You are less than one year old?" Lin Feiyan couldn't help but pause when she heard her footsteps, and almost forgot to walk. She looked at the body of the other party who was obviously five or six years old. It was really hard to imagine that the other party was less than one year old. Moreover, in the previous conversation between her and the two, the little girl was articulate and logical. Even a five or six-year-old child could already be called a young adult.

Normal human children are just babbling when they are one year old!

Is this still human?

Wu Qianru was also a little surprised, with a look of disbelief.

"I'm one of the fast-growing group. Most of the younger siblings grow slower." Seemingly noticing the surprised expressions of the two, the little girl lowered her head and said a little shyly.

"Are other people as smart as you?" Lin Feiyan asked.

"No, some people are stupid, such as the younger brother with the number A51621, who only knows how to play every day, and doesn't do the homework assigned by the teacher. As a result, he didn't even finish elementary school. I have already finished junior high school and started to study high school. Lesson is over." The little girl raised her chin slightly and said with some pride.

"Then... you're really amazing!" Lin Feiyan, who used to be a scumbag, was tongue-tied and didn't know what to say. Then, she changed the subject and asked, "By the way, you've been outside for so long, what do you eat every day? ah?"

"I haven't eaten for several months. Sometimes I'm thirsty and want to eat ice cubes. The ice cubes are too dirty, but I can't help my thirst, so I finally chewed them up and swallowed them. I'm so pitiful!" As he spoke, he seemed to think of the grievance, and when his mouth shrunk, tears fell down.

The two women felt pity in their hearts when they heard it, and hurriedly comforted her. Seeing that she hadn't eaten for several months, they didn't care about the shock, so they simply left in no hurry, put down their backpacks, and prepared to eat.

...

Mayor, this is the result of a geological survey underground in Hope City. "An engineer tremblingly handed a stack of documents to Luo Yuan.

With a blank expression on his face, Luo Yuan took the blueprint, quickly flipped through a few pages, suppressed his efforts, and said in a deep voice, "This is your report, how could it be so serious!"

The officials behind him and the leaders of the waterworks factory turned pale with fright, their hearts were beating wildly, and they dared not even take a breath.

No wonder he was furious, it was really a big mistake this time:

"You didn't start the geological survey until something went wrong. What's the use of raising you people." Luo Yuan walked back and forth with a gloomy expression.

Hope City relies on groundwater for both drinking water and domestic water. However, the geological structure map shows that this underground river, which is more than 300 meters deep underground, is on the verge of drying up. There was a huge hole.

According to estimates, Hope City will be without water within five days at most.

But this is not what makes him the most angry. The most angry thing is that everyone did not investigate and detect the groundwater before that. It was not until today that the bottom of the dungeon suddenly collapsed, and the problem was finally exposed.

If there is no collapse, maybe there will be a big riot in Hope City.

Looking at the person in charge who was frightened by his leaked breath, his face turned pale, Luo Yuan took a deep breath, and his heart gradually calmed down. If we really want to say it, we can't blame these people entirely. Back then, he put all human scientific research The personnel and most of the technicians were transferred to the spaceship, resulting in a serious shortage of talents in the water bed. Coupled with the indifference to the subjectivity of Hope City, hidden dangers have been laid for everything today.

"Tell me the reason?" Luo Yuan walked to the collapsed place and said lightly.

"We ignored the impact of the ice layer on the groundwater. The existence of the ice layer on the ground hinders the water cycle, so that the precipitation cannot go deep into the ground to replenish the groundwater." The factory manager explained profusely.

Luo Yuan's face was expressionless, and he couldn't see the slightest emotion, which made the factory manager even more frightened.

In fact, the water problem is still secondary. The biggest problem today is how to solve the impact of the underground cavity on the entire dungeon.

This floor was originally idle, but after the disaster, it was transformed into an agricultural area. As the bottom of the underground building, the firmness of the foundation determines the stability of the entire dungeon. Once it is unstable, the entire dungeon may collapse. .

Although the landslide area this time is not large, only a few hundred square meters, it does not have much impact on the stability of the overall structure of the underground city, but its appearance is already an omen, the cavity has formed, and the structure has been destroyed, even if the pumping is no longer continued There is no guarantee that the collapse will not continue.

Maybe a small earthquake can break the camel's straw and trigger a chain reaction.

"How much water does the factory have?" Luo Yuan asked.

"Normally, it can be used for three days." The person in charge of the factory quickly replied.

Luo Yuan breathed a sigh of relief after hearing this: "Stop pumping water from now on!"

"Yes!" Hearing what the mayor meant, he was still in charge of this matter, and the person in charge of the factory immediately said with amnesty.

"In addition, I want to ask, how are you going to solve this underground cavity." Luo Yuan asked.

"Pour in the soil mix, or drive in a lot of piles!" suggested a civil engineer.

Secretary Cheng Guanghui reminded from the side: "Mayor, the cement inventory is running out, and it is estimated to be less than 100 tons!"

Luo Yuan is also aware of this matter. In order to deal with the frequent earthquakes after the disaster and strengthen the underground city, Hope City built a lot of load-bearing columns, and the cement inventory was consumed like a flood, and there was already very little left.

In fact, not only cement, but also all kinds of other reserve resources have almost been consumed. If Luo Yuan had already found a way out, human civilization would probably only be nestled in the city of Hope, and then slow down under internal and external difficulties. withering.

"If you don't have cement, you can also use water, and the presence of water can greatly support the geological structure."

Luo Yuan nodded. The reason why the underground river has collapsed now is that the underground river has dried up. Replenishing it with water is also a solution, but this matter will not be resolved in a short while. He looked at his watch and said to Cheng Guanghui: "Notice The leaders of the various cities have a meeting at 4 p.m.!"

"Okay, mayor, I'm leaving first!" Cheng Guanghui said respectfully. It was already past three o'clock, and the time was running out. He wanted to return to the office as soon as possible and call the city leaders one by one. The strong electromagnetic pulse caused by the explosion of the antimatter bomb destroyed most of the communication equipment, and the only old and easy-to-repair landline phones that can still be used today.

Luo Yuan nodded, and continued to inspect the waterworks. When he saw the huge water storage tanks in the factory area, his face slightly improved.

Although after the nuclear winter, water resources have become extremely abundant, the thickness of the ice layer above the surface has reached tens of meters, if it were all turned into water, it would be enough to form a vast ocean.

However, it is quite difficult to mine these ice cubes. First of all, it is extremely hard. Under this extreme cold, steel will become extremely brittle. Ordinary metal tools are useless at all, and it takes time and effort. Secondly, even if the mined ice is melted, it cannot be drunk directly. One-third of the mass of the ice is solid impurities and there are a lot of electrolytes dissolved in water, which must go through a series of complex physical and chemical treatments.

And all of this will undoubtedly take time.

Now there are three days to buffer, it should be enough.
