Chapter 399

Chen Xin is not surprised that his survival has exceeded six figures, and even thinks that it seems a little less.

This is the benefit of cooperation with the state. Chen Xin can also get survival if he helps others indirectly. Therefore, by improving the living conditions of others on a large scale, the state can naturally bring him a large number of survival.

In fact, if the production of isotope batteries had not increased, Chen Xin would have gained more survival points.

So this is the reason why Chen Xin is less and less concerned about the growth of his own survival points, because there is really no need to pay much attention to it. As long as he confirms that he will not spend it all at once, a large number of survival points will be recorded again in a few days.

With a large number of survival points, Chen Xin has enough confidence and strength to do what he wants to do. He doesn't have to worry about survival points any more.

If Chen Xin didn't choose to cooperate with the country at the beginning, but only slowly saved his own survival points, he might have saved a year, which may not be as much as the current day.

After all, the survival base that a country can provide is too large. Even if there is a single acquisition limit, as long as the number goes up, the total amount will naturally go up.

As for the fact that there are only private refuges, no matter how they develop, the speed of development can not be compared with that of a country.

Chen Xin once thought carefully that maybe this is the real usage of the doomsday survival system he obtained.

After all, before disaster and doomsday, personal heroism is meaningless. Only when we unite and gather the strength of all people together, can we do more things and let more people live, rather than just a few people, even the continuation of civilization and population.

Chen Xin doesn't want to be the hero in the early stage, and he doesn't think he can lead other people. It's good for him to be an assistant of exporting black technology like this.

Just like when playing RPG at the beginning, Chen Xin preferred to play the role of assistance and treatment in the team rather than the role of output or tank, and he didn't want to be the team commander, although his command ability was not bad.

Although Chen Xin doesn't want to be a leader now, when a large group of people around him, he is naturally placed in the position of leader, which makes him have to think about the next way.

According to Chen Xin's idea, he is planning to build an ecological dome in this part of his home.

This is not a whimsical idea, nor is it something that can be realized even if we have a system.

When many people hear about the ecological dome, the first thing they think of is the kind of protective cover that covers the whole city in science fiction. They think it's a very black technology.

But in fact, the ecological dome has been mentioned before, and human beings have built similar existence long ago.

The famous Biosphere 2 experiment is actually an ecological dome, but it is not built into a spherical dome, but a square stepped pyramid structure.

The whole project was built in the 1980s. At that time, technology was not as advanced as it is now, so its structure could not really build a large spherical dome.

Limited by various technical problems at that time, the Biosphere 2 experiment finally failed, unable to achieve internal circulation and independent of external materials.

However, with the development of science and technology, the technology of large-span spatial structure has become more and more mature, and the internal space of related buildings is also more and more broad. It is not a problem to build a small ecological dome.

As for the ecological cycle inside the ecological dome, if we really want to build an ecological circle completely isolated from the outside world, on the premise that Chen Xin does not use the system upgrade, it is certainly not enough.

But it's not easy to build an environment similar to a plant greenhouse.

After all, the most important air and water can be imported from the outside, so it is not difficult to maintain the operation of the whole ecological dome under such a premise.

According to Chen Xin's design, the plan is to build a large dome on the ground with a span of about 500 meters, covering the area in front of the mountain where his refuge is located.

Then raise the temperature of this area, and build scientific research buildings and military barracks in this area.

Although the construction of a large dome with a span of about 500 meters is very difficult, it is not impossible to complete with Yanguo's infrastructure capacity. After all, it is not impossible for large airports, stations and gymnasiums to have a larger space span.

In addition, Chen Xin does not plan to build a hemisphere to buckle on the ground, but only plans to build a flat arc dome. The construction technology is not as difficult as he thought. Even if there is no support column inside, it can be built.

When there is a relatively closed environment, as long as the building materials are enough thermal insulation, and there are enough heating facilities inside, it is easy to create a warm enough greenhouse environment.

As for scientific research bases and military barracks, when the dome is built, all the buildings can be completed by the way.With the suitable temperature in the greenhouse environment and the stable supply of fresh water, it is not difficult to plant and build a small ecosystem.

Even if a small ecological dome has all the elements, there are too many things involved in how to make the ecosystem self cycle, which is not what Chen Xin can do.

But fortunately, he has a system, and any problems will be solved as soon as he upgrades.

Even if there is no need to upgrade the system, it is still possible for the state to send two biologists to help build an ecosystem with stable circulation.

For Chen Xin, of course, he won't use the sharp weapon of system upgrade, and he won't say that he is working hard alone.

At that time, let the state send biologists to build the ecological system, and then upgrade and optimize the system by themselves. In this way, we can create a comfortable ecological dome and recreate the scene of the past under the snow and darkness!

Of course, such an ecological dome is not for enjoyment. Although it is a kind of enjoyment to live in such a warm and comfortable ecological dome with green ecological environment in the present environment, the establishment of the ecological dome is also of great scientific significance.

The large-span spatial structure can be used not only to build ecological dome, but also for large-scale planting greenhouse. The small-scale ecological cycle can not only create a comfortable green ecological environment, but also help to study circular ecological agriculture.

It can be said that the technology of building ecological dome can be used to build planting greenhouse.
