Global Cataclysm: Infinitely Upgrade Shelter

After Zhao Chen returned to the shelter, he took on a system mission of 200 survival points.

For Zhao Chen, the task of this system is very simple, that is, to check what the shelter lacks, and the overall damage to the facilities.

For a task like this, Zhao Chen naturally hopes that the more the better.

The outermost part of Zhao Chen's shelter was dirt, and the dirt was thick rock.

Next to the thick rock are some metal silicone, as well as compositions such as fiberglass.

These three layers of shell formed the outermost part of Zhao Chen's refuge.

In addition to these things, there were some special patterns carved into the inside of the shelter, and Zhao Chen couldn't figure out what these patterns were for. It's just that there should be no waste products at all when the system is produced.

At the very top of the shelter is thick glass, which is transparent.

Although the thickness of the glass is very thick, it does not affect the overall lighting situation. On the top of the shelter, the reason why Zhao Chen chose transparent glass when he built it before was that the sunlight needed to shine through the relevant facilities inside.

If the glass is not transparent, then it is difficult for sunlight to penetrate Zhao Chen's shelter, which has a great impact on Zhao Chen's shelter.

If the shelter was in a dark situation for a long time, even if there was daily lighting, Zhao Chen and they would not be used to it.

Human exposure to sunlight has great benefits, not only to promote bone fusion, but also to kill some viruses and bacteria.

The benefits of sun exposure are many, no matter how tightly protected Zhao Chen's shelter is, but these basic elements are guaranteed by Zhao Chen.

Sunlight can also directly illuminate these plants in the shelter, creating photosynthesis.

This is the fundamental reason why Zhao Chen let the sunlight shine in.

It's just that the sunlight doesn't shine in directly, and the nearly 50 square meters of glass on the ceiling are not ordinary glass.

These glasses consumed nearly 1,000 survival points for Zhao Chen.

The glass in the ceiling has a total of three functions.

First, discoloration. Zhao Chen can control the glass on the ceiling to change color through his own control in the shelter. If Zhao Chen changed the color inside the shelter to black, then it would be impossible for sunlight to shine through the glass. Zhao Chen added some special materials to the glass, which can block sunlight.

Of course, these things are under his control.

The discoloration can ensure that when Zhao Chen does not need to let the sunlight in, he can maintain a dark environment, and sometimes it is not only conducive to promoting sleep. It also improves the comfort of the shelter.

Second, heating. By changing the thickness of the glass, Zhao Chen can directly use sunlight for heating, thereby reducing the loss of electricity. Solar energy has been used a lot in peacetime before, and now it has been systematically upgraded, and this role has become even more obvious. During this time, basically all the electricity consumed in Zhao Chen's shelter came from solar power generation.

The use of solar power generation greatly saves the consumption of resources in Zhao Chen's shelter.

These are the two biggest functions of these two pieces of glass.

As for the third role, it is very simple - to provide spectral research for Ying Mengyao.

These are the three functions of the glass on the ceiling.

The three effects are particularly useful for Zhao Chen's refuge.

There is also a layer of metal shell on top of the glass, and when light is usually needed, Zhao Chen unfolds the metal shell without affecting the sunlight. If Zhao Chen doesn't need sunlight and needs to prevent other disasters at the same time, Zhao Chen will add a metal shell.

A controllable refuge like this would be inflated in peacetime.

Zhao Chen's refuge is now developing very well.

In addition to solar power generation, the biogas digester inside Zhao Chen's shelter also came in handy.

The main raw materials for Zhao Chen's biogas digester are sewage treatment from the shelter, as well as animal manure.

In Zhao Chen's shelter, there are chickens, ducks, rabbits, fish and so on.

Zhao Chen loves to eat these animals, especially chickens and rabbits.

It is also very delicious when it is combined with rabbit fish, but because the fish has fish bones, it is also very troublesome to handle.

Zhao Chen prefers to eat fish, but he is not very easy to handle fish bones. (If you read a violent novel, go to Feilu Novel Network!)

He still prefers the feeling of eating meat in large chunks.

Zhao Chenxing made a round, and he found that there were basically no lacking facilities in the shelter, and some of the damaged basic props were also repaired by her simple treatment.

At this time, the sound of a system prompt sounded in Zhao Chen's mind.

[Congratulations on completing your daily patrol mission, and congratulations on obtaining 200 survival points.] 】

Zhao Chen heard the prompt sound of the system, and his whole heart was very happy.

The sound of the system prompt is very dense, and whenever there is a system prompt, Zhao Chen is very happy in his heart.

Not to mention anything else, the system prompts, which means that there is a new mission or a new survival point in the account.

The more survival points, the more Zhao Chen's safety can be guaranteed.

Even if he tries all kinds of methods, Zhao Chen will increase his survival point.

Later, when building a gravity field, it costs a total of 20,000 survival points. If Zhao Chen doesn't accumulate survival points in time, there will only be more and more survival points that need to be consumed in the future, and there may be no situation at that time.

In order to avoid these 140 situations, Zhao Chen will try his best to accumulate survival points as much as possible.

After Zhao Chen inspected the circle, he prepared to go to the cave and dispose of all the saplings in the cave.

Because of the hail rain before, Zhao Chen did not spend much money to obtain so many fruit trees, and these fruit trees have now all become Zhao Chen's resources.

Zhao Chen will make reasonable use of these resources.

The idea is very good, but Zhao Chen also has a problem that has not yet been dealt with, that is, where should these fruit trees be planted?

This is something that Zhao Chen did not expect at all.

Don't say anything else.

There are a lot of fruit trees, and there are no hundreds or thousands of acres of land that can completely reproduce these fruit trees.

Zhao Chen could transplant some fruit trees into his shelter, but the overall scale and scope of his shelter were not that large after all.

There are no more than a few fruit trees planted in Zhao Chen's shelter.

Since this is the case, Zhao Chen can only think of other ways to solve these fruit trees from other aspects.

These fruit trees themselves are ripe fruit trees, Zhao Chen only needs to plant them, and every certain season, these fruit trees will all bear fruit.

The fruits of these fruit trees, Zhao Chen can not only be used for food. Similarly, Zhao Chen can also use the fruits of these fruit trees to make preserved fruits.
