"By the way, do you already have a plan for the planning of the cave space?" Shan Yufeng changed the subject. Pen, fun, pavilion www. biquge。 info

"The preliminary plan has been made, and the materials are currently being counted, and the plan will be adjusted according to the material reserves, and the advance preparations can be carried out in about a week. Li Ni replied immediately.

"Tell me about it, you don't need to be too careful, just tell me about it. Shan Yufeng didn't expect the speed of the country to be so fast, and said curiously.

He really wanted to know how the country was prepared to relocate more than a billion people.

"Okay, the initial plan is this. Within three months, materials will be mobilized into the cave space, and oxygen circulation devices will be mainly installed to ensure the balance of the internal space atmosphere.

Then a floating platform was built, on which all the transferred personnel were placed. Houses will be built later, but they will not be able to be built in a short period of time.

All the land in the space is used for cultivating food, and vegetable and livestock breeding can only be built on a suspended platform, otherwise food production cannot be guaranteed. All this needs to be done in seven months, and there is only one month to move the population, which is the preliminary plan. ”

After listening to Li Ni's plan, Shan Yufeng's brows furrowed, and he didn't understand some of the questions.

"All the land is used to grow grain, everyone can only live on the suspended platform, and the country has no grain reserves?" Shan Yufeng was puzzled, isn't the country's grain reserves claimed to be able to eat for three years?

"At present, the country's grain reserves are only enough for everyone to eat for three months, and all the land in the space is only equivalent to the output of 450 million mu of arable land. Before the catastrophe, the grain produced by China's 1.8 billion mu of cultivated land was not enough for us to consume, and we still needed to import grain to meet our needs.

Of course, this is also the reason why we wasted food before the catastrophe, but no matter how you calculate it, 450 million acres of arable land cannot meet the consumption of one billion people, so while all the land is used for arable land, we also need to build suspended platforms to produce food. ”

Li Ni didn't think about it, and said directly, as if all the data was in his head.

Shan Yufeng didn't speak after listening, at first he thought that the area of 280,000 square kilometers was already very large, but now it seems that it is not enough to grow food.

"Okay, let's not talk about food, can the floating platform built in seven months meet the needs of more than a billion people?" Shan Yufeng asked again.

"Basically, it's okay, the floating platform we designed is actually a simple skyscraper. Each floor is about one square kilometer, with a distance of three meters between the top and bottom, and a steel frame bed can be placed every four square meters, and a steel frame bed has four layers, so that a minimum of four people can live, and a maximum of eight people.

The first floor of the suspended platform can place 250,000 steel frame beds, which can accommodate 1 million people, and each suspended platform has a total of 50 floors, which can accommodate a total of 50 million people. About 25 floating platforms can accommodate everyone, but of course, this is only the ideal situation, and it does not take into account the occupied area of other public facilities.

But in any case, according to this construction method, how can 45 suspended platforms meet the minimum living needs of all people. Li Ni explained.

Shan Yufeng was convinced, he could think of this method, what else could he say.

But think about it, either you don't die, or you live on this kind of floating platform that is more humble than a tube building, and fools know how to choose.

It's not good to live, but it's better than not dying at all.

The two talked as they walked, and soon came to the top floor of the Academy of Sciences.

On this floor, Shan Yufeng saw that above the holographic projection system, a huge model of the earth was slowly rotating, and various data were marked next to it.

"What is this?" asked Shan Yufeng, pointing to the huge earth projection.

"The holographic data simulation system, which is powered by 68 supercomputers, concentrates the data collected by all the detection equipment in the country, calculates and simulates it through physical formulas, and finally forms this holographic projection that can feed back all the current state of the earth. Li Ni said with a smile.

Awesome, what else can Shan Yufeng say besides these two words.

The Otherworld is indeed powerful, and the power can pick up the stars with one hand. But they really can't make a holographic simulation system like this.

Shan Yufeng walked into the projection earth, and he wanted to see up close how real the data given by this holographic simulation system was.

"Uh...... This countdown to the destruction of the earth was also created by you. Shan Yufeng looked at the top piece of data, and the corners of his mouth twitched.

When he saw the countdown, he suddenly remembered the time marked every day in the black and white of the college entrance examination.

"Yes, according to the various data collected by the probe, and finally calculated as a whole, the time of destruction of the earth is obtained. ”

There are 297 days left until the Earth's magnetic poles rotate.

There are 442 days left before the Earth Mass drifts.

...... distance from global volcanic eruptions

The countdown line by line, indicating the imminent fate of the Earth, is marked by the red font on the last line, and there are 1,574 days left before the Earth becomes the Death Star.

"Three years, I didn't expect that in three years, the earth will become a death star, what kind of planet will the earth become at that time?" Shan Yufeng took a deep breath and said in a low voice.

"Mars, then the Earth will become another Mars. Li Ni replied.

"Will the Earth become Mars?" Shan Yufeng was stunned, he never thought that Li Ni would say such an answer.

"That's right, as the Earth's core cools, the Earth's magnetic field weakens to a limit, when most of the gases in the atmosphere dissipate, leaving only a little bit. The winds inside the earth will continue, all living things will die under the direct rays of various cosmic rays, most of the seawater will evaporate, and the rest will be completely cooled, and the whole earth will become what Mars is now. ”

Well, become Mars, Shan Yufeng couldn't help but think of the lines in a movie back then.

Earth is too dangerous, you might as well go back to Mars.

Human beings used to think about landing on Mars every day, and there are plots to transform Mars in various science fiction novels.

But now, when the Earth is really about to become Mars, humans can only build spaceships and leave the Earth.

"By the way, have you studied the genes of the Zerg Brood, why can it quickly change the structure of cell tissues?" Shan Yufeng transferred to a biological research center, and as soon as he arrived here, he remembered the Brood and immediately asked.

"One has been researching since five years ago, but in five years, we have only got one answer, that is, the cell tissues that make up the mother nest will face genetic collapse at any time.

But in fact, the cell tissue of the mother nest is more difficult to deal with than any virus, even if it may genetically collapse with it, but no matter how we change its genetic structure, it just won't collapse.

It can be said that its genetic structure, with the current level of science and technology on the earth, is simply incomprehensible. Li Ni shook her head and replied.

Shan Yufeng was speechless, what to do with so much talk, in the end it was not a sentence, and he didn't study the fart.
