Doomsday Bunker Upgrade

Chen Xin didn't find it very strange that his survival point had exceeded six figures, and even thought it seemed a bit small.

The advantage of cooperating with the state is here, because by indirectly helping others, Chen Xin can also obtain survival points, so through the country's large-scale improvement of other people's living conditions, it can naturally bring him a large number of survival points.

In fact, if it weren't for the fact that the production of isotope batteries had not increased, Chen Xin would have been able to obtain more survival points.

So this is why Chen Xin is less and less concerned about the increase of his survival points, because there is really no need to pay too much attention. As long as he confirms that he will not spend it all at once, after a few days, he will have a large amount of survival points again. Accounted.

And with a large number of survival points, Chen Xin has enough confidence and strength to do what he wants to do, so he no longer has to worry about the problem of survival points.

If Chen Xin didn't choose to cooperate with the country at the beginning, but just slowly accumulated survival points, he might have saved for a year and may not have grown as much in a day as he is now.

After all, the base of survival points that a country can provide is really too large. Even if there is a single upper limit, as long as the number increases, the total amount will naturally follow.

As for only private sanctuaries, no matter how much it develops, the speed of development cannot be compared with that of a country.

Chen Xin also thought about it carefully, maybe this is the real usage of the doomsday survival system he obtained.

After all, before disasters and doomsday, individual heroism is meaningless. Only when everyone unites and brings everyone's strength together can more things be done and more people live, not just So few people survived, and even the continuation of civilization and population could not be achieved.

Chen Xin doesn't want to be that early hero, and he doesn't think he can lead others. It's actually quite good for him to be an assistant that outputs black technology.

Just like when he was playing RPG games, Chen Xin prefers to play the role of assistant and healer in the team, rather than the role of output or tank, and he has no idea of ​​being the commander of the team, although his commanding ability is actually not bad. .

Now, although Chen Xin doesn't want to be a leader, when a large group of people surrounds him, he is naturally put on the leader's seat, which also makes him have to think about the next path.

According to Chen Xin's vision, he intends to turn the location of his home into an ecological dome.

This is not whimsical, nor is it possible to do whatever you want with the system, but something that can be realized from the perspective of real technology.

When many people hear the ecological dome, the first thing they think of is the kind of protective cover that covers the entire city in science fiction, thinking that this is a very black technology.

But in fact, the ecological dome has been mentioned before, and humans have built similar existences a long time ago.

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

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

And due to the various technical problems that existed at the time, the Biosphere-2 experiment eventually failed, unable to achieve internal circulation and not relying on external substances.

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

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

But if you just build an environment similar to a plant greenhouse, it's not too simple.

After all, the most important air and water can be imported from the outside world. It is not difficult to maintain the operation of the entire 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 to cover the area in front of the mountain where his shelter is located.

Then increase the temperature of this area, and build scientific research buildings and military camps 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 in terms of the infrastructure capacity of Yan Kingdom.

In addition, Chen Xin does not intend to build a hemisphere to buckle on the ground, but only intends to make a flat curved dome. The technical difficulty of construction is not as big as imagined. Even if there are no supporting columns inside, it can be built. of.

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

As for the scientific research base and military barracks, all the buildings can be completed by the way when the dome is built.

With the suitable temperature in the greenhouse environment and the stable supply of fresh water, it is not difficult to grow plants and build a small ecosystem.

In this way, even if a small ecological dome has all the elements, as for how to make the ecosystem self-circulate, there are too many things involved, which is not something that Chen Xin can handle.

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

Even if the system is not upgraded, the country can send two biologists to assist and build an ecosystem that can stabilize and circulate.

For Chen Xin, of course, he would not leave a weapon like a system upgrade unused, nor would he say that he was working hard alone.

At that time, let the state send biologists to build the ecological system, and then use the system to upgrade and optimize it. This two-pronged approach will create a comfortable ecological dome and reproduce the old scene under the ice, snow and darkness. How comfortable it would be one thing!

Of course, such an ecological dome is not for enjoyment. Although living in such a warm and comfortable ecological dome with a green ecological environment is a kind of enjoyment in the current environment, the establishment of the ecological dome also has important scientific research significance. of.

The large-span space structure can not only be used to build ecological domes, but also can be used for large-scale planting greenhouses. Small-scale ecological cycles can not only create a comfortable green ecological environment, but also help to study circular ecological agriculture.

Using the technology of building ecological domes in the construction of planting greenhouses can be said to make the best use of everything.
