The huge mother ship of the Boss is floating quietly in the dark space like a fortress, but now it is the only place of hope for mankind, the future Noah's Ark.

The originally empty living cabin is now full of people. After several migrations, more than 100,000 people have lived in it.

In the alien botanical garden that previously occupied the center, except for biological samples for scientific research, all animals and plants were cleaned up and burned and disinfected. Instead, a roof of tents, one connected to the other, occupying almost the entire residential cabin.

These alien animals, plants and various bacteria and viruses may be harmless to the Belgians, but it does not mean that they are the same for humans. Staying here is a hidden danger after all.

But today, some of the tents here will be moved away!

Because the internal building of the first human spacecraft will begin formal trial production.

In the past three months, with the help of information provided by the Intelligent Brain and the day and night exploration by countless engineers, these factories have been started one after another and have produced various engineering machinery, various infrastructure equipment, and a large number of qualified steel prefabricated parts.

The conditions for humans to transform spacecraft are fully ripe!

At 8 o'clock in the morning, Luo Yuan rushed back to the spacecraft and the project was officially launched after a brief groundbreaking ceremony!

Hundreds of various engineering vehicles began to enter the construction site one after another.

Even Luo Yuan lit up his eyes. These engineering vehicles are still familiar in appearance, but compared to the stupid, big, black and thick machines used in the reconstruction area before, these engineering vehicles all look tall and tall. They are silver-white all over, with smooth surfaces like mirrors, and they look completely integrated. Even some essential parts at joints are tight and seamless, and ordinary people can't see it if they don't look carefully.

The precision processing machinery and advanced material technology of the Boxing people make even rough construction machinery full of mechanical beauty.

But in fact, this is just a light surface of donkey dung eggs. Putting aside everything on the surface, human technology level has not improved, but has declined significantly. The great degradation of human technology after the disaster has been fully demonstrated on these vehicles.

For example, these engineering vehicles have no electronic equipment at all, and most of the technology is only at the level of the 1950s and 1960s (of course, there are also reasons for rushing to work)

For example, there is a lack of fuel here and electric power is required to use power. However, I hope the city's battery technology reserves are completely insufficient to drive these construction machinery that requires high horsepower, resulting in a cable being held on the heads of these engineering vehicles, which makes people feel embarrassed and helpless!

Luo Yuan nodded slightly while listening to the introduction of the chief engineer.

No matter what, humans can at least use it.

On the other hand, the project has begun. A large number of workers drove giant trucks loaded with metal prefabricated parts into the construction site. Looking at this obviously over-spec vehicle, Luo Yuan suddenly felt that using cables is not without benefits. At least if he uses a battery, even at the highest level in the previous reconstruction area, such vehicles cannot be driven.

At this time, Luo Yuan noticed that each of these metal prefabricated parts is 6m*6m in size, but the thickness is only 0.15m, and he immediately wondered:

"Is it okay to be so thin?"

After all, the buildings inside the spacecraft are not ground buildings. During the flight, they often accelerate or slow down. For skyscrapers, their bad situation is even worse. With the strength of ordinary skyscrapers, it is obviously not suitable for spacecraft.

The chief engineer next to him quickly explained: "Mayor, this is a high-strength metal provided by the intelligent brain. Its processes are as high as a dozen. After being released in the smelting furnace, it passes through a series of processes such as demagnetization, electrical and thermal insulation coating, million-ton forging, extrusion, atomic magnetic field sorting, etc., making its strength more than ten times that of an ordinary aircraft carrier deck. After simulation tests, skyscrapers with this thickness can withstand two hundred G accelerations."

Luo Yuan nodded slightly when he heard this. The acceleration of the manned spacecraft is generally progressive step by step, and there are rarely any emergency stops or accelerations. When it really comes, when it is necessary to withstand an acceleration of 200 G, there is no need to wait for the skyscraper to collapse, most humans may have died long ago.

...

Since metal prefabricated parts are all made of metal plates, the metal plates are completely locked with inverted triangle grooves, which saves a lot of welding work and makes the construction of the project very fast. Luo Yuan stayed at the construction site all morning, and by noon, three floors of the skyscraper had been built.

With such a progress, this skyscraper will probably be completed in less than a month.

This will be a super building that is 400 meters long, 300 meters wide and 200 meters high. Once built, it will accommodate a population of 800,000 to 1 million. At the same time, its interior will have a series of residential facilities such as streets, shops, agricultural areas, parks, etc.

You can completely live without leaving your home and self-sufficient. It can be said that a building is a concentrated city. In the planning, a total of twelve such buildings will be temporarily built in the entire residential area. Except for most of them to be used to accommodate survivors, the remaining five buildings will prepare for the future increase in human numbers.

By that time, this empty residential area will now be replaced by a steel forest, all space will be occupied by these twelve super buildings, and there is probably only the streets of each building.

This will be a small city with a population of up to 12 million. It is hard to imagine that such a spacecraft can accommodate so many people.

...

In the afternoon, Luo Yuan inspected various research institutes in the factory area, especially the Genetics Institute for a lot of time. Unfortunately, he is still exploring here.

Laboratory instruments are more complex than factory machines, and many involve gene editing technology and more professional knowledge. Many instruments cannot operate even if they know their functions.

The gene technology of the Boscos has completely surpassed several streets of human beings. According to the introduction of the intelligent brain, the Boscoscos can operate directly at the genetic level like him, adding and modifying DNA at will, and there are countless new gene biology theories.

Of course, compared with Luo Yuan's ability to conduct comprehensive genetic modification on himself, the Boscos can only perform nano-level operations on the fertilized egg, but even so, it is still like science fiction for humans.

The development of science and technology cannot be achieved overnight, but needs to be gradually improved. Before fully absorbing the technology of the Bostons, humans still need to make up for the lessons for a long time, which is also the norm for these researchers today.

Luo Yuan was both disappointed and excited. The artificial synthetic organic molecular technology of the Boscos has matured. During the Boscos' journey to the Earth, all the food in the spacecraft was synthesized using elemental ratios.

There are such miniaturized instruments and equipment in the Spacecraft Research Institute. Once humans master this technology, let alone the future human food can be completely free from the constraints of agricultural areas, even the heart of wisdom can be artificially synthesized.

(Now the intelligent brain of the spacecraft can of course automatically synthesize food according to the process, but after all, it comes from an alien planet, and the biological evolution process is different. Many proteins contain heavy metals, which are toxic to humans)
