Inspired by the Ark of the Last Days, Lin Feng also considered following this line of thought when building this new city. Humanity doesn't know what kind of future it will face, so it is important to prepare for a rainy day.

In fact, for Lin Feng, the difference between building an ordinary city and a city with the function of an ark of something is not very big.

The last days are nothing more than large-scale natural and man-made disasters.

With sturdy houses and an advanced medical system, man-made disasters can be largely avoided.

Natural disasters include large-scale changes in the earth's crust, equatorial and polar shifts, meteorite impacts, etc., and these huge disasters basically cause huge floods, dust that obscures the sky or cold nights that last for hundreds of years.

In the memory of human ancestors, the flood is definitely the first terrible thing, and as for the black night that lasts for hundreds of years, it is estimated that it has not been encountered in the history of mankind.

Therefore, the construction of the new city is still mainly to prevent floods, that is, to build a larger boat.

But for a big ship that can accommodate 10 million people, it is also unrealistic for Lin Feng to have the Universe Mall as a strong backing.

The hull is too large, and the strength of the material required is beyond imagination, and even if it is made entirely of supramolecular polymer materials, it will be easily torn.

If one ship can't work, then build several more and put them together, and if there is really a super flood, the whole city will be scattered into several parts, so as to avoid being wiped out.

Once you've made up your mind, it's time to prepare the planning drawings.

Lin Feng invited hundreds of experts from the Academy of Sciences to jointly design this unique ark of the end of the world.

The engineer led by the Academy of Sciences was Xu Ziqiang, an acquaintance of Lin Feng, who was the chief engineer when the first underground high-speed train passage was built.

After the two communicated their opinions, Chief Engineer Xu had a preliminary plan.

The construction engineer is best at building blocks, so he planned Lin Feng's new city into the style of a nine-square grid. One city and nine bodies, each part has the same function, which can also reduce the trouble of design, and it is more convenient and trouble-free to build.

"The materials you provide can support the main structure of 8,000 meters square," Chief Engineer Xu has studied a lot of new building materials of Linfeng Technology in the past two years, so he has his own furrow in his heart, "In this way, nine small cities are put together, which is 24 kilometers square, 576 square kilometers, and if it accommodates 10 million people, the per capita land area is 57.6 square meters, which is much more spacious than the current Rongcheng."

"Because each individual town has a complete life function, so there is no need to worry about expansion, and when there are more people, just add a few on the side.

"It's the first time I've seen the construction industry turn into an assembly line. ”

Isn't this just an assembly line, with the same scale, layout and facilities, built like building blocks, even if you want to build a city with a population of 100 million, you only need to design it once.

To design a city that functions as an apocalyptic ark, the first thing to consider is the underground structure. With the super battery and the magic eye system, there is no need for wires and communication cables, and the only thing to be placed underground is the subway and running water.

Water is the first need of life, and water is still relatively scarce here in Taklamakan here, so Lin Feng plans to dig a few more tunnels to the Bohai Sea.

In addition to the water supply system and sewerage, there must be an adequate water purification system and garbage disposal system hidden under the city.

In general, the purified water is discharged into the river outside the city, and in the event of an emergency, the domestic sewage can be reused as drinking water through advanced purification.

It may sound a bit hard to accept, but in the past, astronauts in space did just that.

In fact, these are very simple, and underground transportation is the most complicated place.

In a city with such a dense population, the subway must be developed enough to make the streets on the ground appear quieter.

And urban transportation should not only consider a small city, but also combine with the surrounding small towns.

Therefore, Chief Engineer Xu's suggestion is to plan a circular subway passage in the big city of Jiugongge first, and if these cities are likely to be separated in the future, then a single small city will be changed to a reciprocating line.

After simulating the feasibility, Lin Feng felt that this was not perfect enough.

People who live in the city have the possibility to go everywhere, and if they are not on a loop, they have to go through a transfer. Although everyone is more accustomed to taking the subway now, he personally doesn't like it.

"How about we don't use the subway," Lin Feng made a bold suggestion after a few days of thinking, "or let's make the subway smaller and change it into a cable car, and a small car can only accommodate up to six people." As soon as you enter the subway station, enter the carriage, enter any station in the city, and it will get you to your destination in time and quickly. ”

Chief Engineer Xu was silent for a long time after listening to his idea: "Theoretically, it is achievable, but the problem is that with so many people and such a large flow of traffic every day, a very complex set of procedures is required to control these 'cable cars', and there must be no mistakes." ”

It's a software problem again, Lin Feng has always wanted to find a reliable software engineer, but he hasn't found it.

"Do you have any better opinions?" he asked Chief Engineer Xu.

"I could ask you to recommend someone, but he may not be available. ”

"Who?"

"Liu Qingyi postdoctoral fellow. ”

Lin Feng naturally knew Liu Qingyi, and the two were discussing the selection and education of geniuses together not long ago. But isn't this person better at paperwork?

"Dr. Liu is the best at logical analysis among the people I have ever met," said Chief Engineer Xu, "Of course, we don't need any logic for this program, but designing and planning the track line requires a strong memory and logical ability, otherwise it will be half the effort." Actually, I can make this one, but I'm afraid it will take two years or more.

"If Dr. Liu can help, I guess only two months will be enough. ”

Lin Feng tried to contact Liu Qingyi, but the other party did not agree, nor did he not agree, saying that he needed to ask for instructions.

This request was a week, and when Lin Feng received his call again, it was not good news.

"I'm sorry, but I can't be separated from my work. ”

Lin Feng didn't have any intention of forcing him, it was a big deal to find more people and spend more time.

I didn't think about Liu Qingyi and continued: "But if you can pick up and drop off every day, I think I can spare four hours of private rest." ”

Lin Feng smacked his words, it seemed that Liu Qingyi was trying to bypass some people's sight. It seems that at the top level, there is no consensus on Lin Feng's construction of a new city.

However, since he was willing to take the risk to help, Lin Feng owed him a favor, and the two of them made an appointment on the spot.

At six o'clock in the afternoon of the next day, Lin Feng drove the Shenxiang to the sky above a high-end community in the capital, and in stealth mode, let the belly of the plane as close to the roof of a building as possible.

Liu Qingyi was wrapped in a black windbreaker, and boarded the Shenxiang without attracting anyone's attention, and as soon as he came up, he nagged and said, "It's been a long time since I've done this kind of thing, and I feel a little unaccustomed to it." ”
