Zhou Chen glanced at it casually and found that the book in the girl's hand was called "Biological Reaction Engineering", and what she was reading now was a chapter called "Microbial Reaction Kinetics". Pen, fun, pavilion www. biquge。 info

The biggest feature of this chapter is that there are many formulas involved, and at this time, the page that the girl is turning shows a large number of complex reaction kinetic formulas, and she has not turned the page for a long time.

Zhou Chen estimated that the girl must have been stumped by these formulas.

Thinking of this, Zhou Chen couldn't help but smile dumbly, looking at her frowning slightly and looking distressed, it had a different charm.

"There's a beautiful girl sitting next to me, and it doesn't look so boring along the way." Thinking so, Zhou Chen had a faint smile on his face, leaned back on his seat, closed his eyes and pretended to sleep.

……

At this time, in the far reaches of deep space.

In stark contrast to the calm and quiet surroundings, Jupiter's orbit presents a very lively scene. If you zoom in closer, you can see that between the asteroids of the Trojan Group and Ganymede, countless engineering robots are tirelessly traveling back and forth.

The asteroids of the Trojan Group have become natural mining areas for these engineering robots, forming a slender and long transportation channel like silk threads, which are nervously and busy transporting supplies to the vicinity of Europa. On the other side, there are also some engineering robots that go to another natural treasure trove of resources, the asteroid belt, and also build a transportation channel that surpasses the void and continuously transports back resources.

Of course, for Jupiter, which is close at hand, it is impossible to ignore the existence, and a team of robots dedicated to collecting hydrogen and helium as an energy source are tirelessly and tirelessly traveling to and from Jupiter's surroundings, like industrious little worker ants. It has become one of the few restless landscapes in the solar system.

At the same time, the Earth Fleet station near Ganymede is growing little by little, and various buildings with a clear division of labor are being created in the midst of extensive and intensive construction.

The buildings are divided according to their functions and placed in different positions neatly and rigorously, and in the core area of the complex, there are several particularly large fortifications that are particularly cared for: the huge docks!

As the saying goes, sharpening knives is not wrong for woodcutters, and if a fleet carrying the heritage of civilization wants to sail safely in the universe, it must be indispensable to provide security protection combat ships. Zhou Chen learned a lesson from the experience of the Odo civilization, although the universe is vast, it looks very calm, and contains infinite hope for life and civilization, but at the same time, it also contains crises, and it is the graveyard of countless civilizations! If a weak civilization enters the "pasture" of a strong civilization, it is equivalent to being exiled by fate, and it is difficult to have any hope of survival.

Therefore, the most indispensable thing for a fleet is the escort force!

But at the same time, as the main task of the Earth fleet is to evacuate mankind, the construction of large transport ships and residential ships is a prerequisite for ensuring the evacuation of mankind. There is a straightforward truth in front of us -- the number of transport ships and residential ships directly determines how many people can evacuate the earth in the end.

If the priority is simply the number of people, it is natural to build as many transport and residence ships as possible. But in fact, this is unrealistic, in 45 years, even if we go all out to build transport ships and residential ships, we can't meet the needs of so many people on the earth to evacuate at the same time, let alone allocate a part of the production capacity to build a convoy force!

Therefore, how to coordinate the quantitative ratio of the two is a complex calculation that weighs the relationship between the two forces.

Of course, this problem does not need to be bothered by Zhou Chen for the time being, because at this stage, neither is the focus of construction!

What is the most important task of the Earth Fleet at present, it is not to build the interstellar warship that Zhou Chen dreamed of, nor to build a large transport ship and residential ship that will carry hundreds of millions of people off the earth, but some basic supporting projects and various processing plants that can continuously expand the production capacity of shipbuilding!

How to achieve as much output as possible within a limited time limit in the initial stage with limited production capacity is probably a relatively simple calculation. It's a math problem, like the requirement to produce as many parts as possible in a year with limited manpower. Will we put everyone into the production and processing of the final parts, or will we recruit and build more production lines with the original manpower as the skeleton to expand the production capacity?

There is no doubt that anyone with a modicum of math will choose to expand their factories and increase their production capacity.

This is the current situation faced by the Earth Fleet, which is now a veritable "entrepreneurial beginning", which can rely on nothing more than robots that can be called by a few remnant ships, and these robots are limited in number, all of which are undoubtedly a drop in the bucket in the construction of warships, transport ships, and residential ships. Therefore, after Dandan's accurate calculation, Zhou Chen finally decided to improve the construction capacity of the Earth Fleet first.

First, build a steady stream of engineering robots by blasting troops, then build sub-bases, and then choose the right time to build combat ships and evacuate ships. This is definitely the most feasible option at the moment.

Of course, Zhou Chen also considered the means of going through the state, but this idea was ruled out by him as soon as it emerged.

The power of the country is certainly strong, but the construction of alien ships is not achieved overnight. It is a systems project, which is incredibly complex and involves a huge amount of material supply and a huge amount of manual training. It may take several years just to train qualified construction personnel, and if you count the specific construction time, the normal construction period of a habitual ship tens of kilometers long may take at least 15 years, or even 20 years.

And that's without counting metal smelting and dockyard construction.

While pressure makes people progress, it may also give rise to another great leap forward in the science and technology of the earth. However, the progress of science and technology cannot jump out of the framework of reality, Zhou Chen estimated that in 45 years, the world can build ten ships is already a great achievement. Not to mention that the size of the hull has nowhere to hide, and the social turmoil that may be caused after the official start of construction will outweigh the losses.

Moreover, in addition to the difficulty of building in various countries, there is another point that Zhou Chen is most worried about. If ships are built with the help of the hands of the state, the question of the leadership of the future fleet is also involved. This is a very real problem, so after careful consideration, Zhou Chen still decided to build alone in outer space!

Wait until the fleet is mature, and then carry out the immigration plan through the countries of the earth.

……

The speed of high-speed rail is fast, and the comfort of riding is difficult to compare with other trains.

Thanks to the application of technologies such as seamless rail technology, vehicle design technology and vibration absorption levels, the vibrations of the carriage are controlled to a minimum even at speeds of up to 300 km/h.

If it weren't for the slight tilt of the car body when turning and the sound of the train announcing the station, after closing his eyes, Zhou Chen would not even be able to know whether the train was moving or stationary.

This is somewhat like the "ideal elevator" experiment conceived by Albert Einstein in order to promote the special theory of relativity: a person in an elevator, he cannot determine his true state of motion, whether he is in free fall with the elevator or in space without gravity with the elevator; Or is the elevator moving in a straight line with him at a uniform acceleration, or is the elevator stopping on the surface of the earth.

There are two possibilities for one experience, and this undifferentiated experience that cannot discern the real state is called the principle of equivalence in physics.

Nature is so miraculous that when the sense of sight is lost, the perception from other organs can blind the truth and lead people into a wonderful paradoxical situation.

Two hours later, the train passed through Jinan Station.

At this time, the carriage was very quiet, the conversation between them stopped, the noise of the children also disappeared, and everyone seemed to be starting to fall into the fatigue of the journey.

At this time, Zhou Chen had just woken up from sleep, and he found that the girl sitting next to him was no longer watching "Bioreaction Engineering", but clasped her hands around her chest, leaning on the seat and looking sideways at the scenery outside the car window.

A touch of sunset from the west shone on her face, making the edges of her bangs glow with a faint golden glow, like the picture in a propaganda poster, there is an indescribable beauty.

Zhou Chen couldn't help but praise in his heart after seeing this scene.

A few minutes later, he got up and went to the bathroom.

He didn't notice that the action of getting up caught the girl's attention, and she turned her head to look at him slightly.

In fact, girls have been paying attention to Zhou Chen for a while, not because Zhou Chen is personable and easy to attract the attention of girls. It's because she's never seen anyone start sleeping as soon as they get on the train, and they sleep for more than two hours.

"This guy went to be a thief yesterday?" Yang Xi looked at Zhou Chen's back, and a thought flashed through his mind as if he was conditioned.

But soon she realized that she didn't seem to need to care about this, which was really inexplicable! She shook her head, no longer thinking about anything superfluous.

Within a few minutes, Zhou Chen came back and washed his face by the way.

He was already refreshed at the moment, and when he returned to his position, he took out a journal and magazine and read it.
