Doomsday Bunker Upgrade Chapter 4: The second preparation is to accumulate grains.

　　 Yan Country re-cleared all the air-raid shelters dug that year, and carried out overhaul and maintenance in the shortest time, and upgraded and expanded in the following time, to ensure that the refugees hiding in it can be bigger The chance of surviving.

　　At the same time, the underground rail transit systems of major cities are rapidly being transformed, with alternate lines being used, subway stations being rebuilt and expanded, and underground transportation networks connected...

　　 A series of work is going on in full swing. With a series of strong controls such as curfews imposed by the country, although news of the meteorite hitting the Blue Star has spread like wildfire, the overall social situation is fairly stable.

At least Chen Xin's refuge was successfully excavated, and because he saw the opportunity early, he was able to stock up enough emergency food to eat for at least two years by himself.

However, in terms of drinking water, he can store less. Even if a large water tank and a sewage treatment cycle are designed in the shelter, considering that the next hundred years of extreme cold and long nights will be faced by human beings , He still felt tremendous pressure to survive.

　　 But when things have reached this point, he can only do his best to collect storage-stable bottled drinking water. It’s a little bit more to save.

　　 It’s just that everyone is rushing for shopping at this time. Bottled drinking water and emergency food have become the most urgent items. All supply channels are in short supply. It is very difficult for Chen Xin to even want to replenish more goods.

　　 Fortunately, Chen Xin joined a small group formed by a group of outdoor sports enthusiasts. After the news of the meteorite impact spread, the group friends in the group used their own resources to save themselves. Many people Like Chen Xin, prepare to dig a shelter by yourself.

And the group friends in the group suggested that the empty tap water can be used for storage, which allowed Chen Xin to reserve a lot of fresh water resources.

Although bottled tap water is definitely not as durable as bottled pure water, and there are some problems in drinking, but under extreme conditions, even urine has to be drunk, and even water from feces is required. Tap water that is not clean at all counts. What happened?

　　Chen Xin’s city is located on the banks of Dongting Lake in the middle reaches of the Yangtze River. The population density is not high. For some personal reasons, he did not live in the city. Instead, he lived alone on the outskirts of the city. The mountains and forests were near his residence. It is very convenient to dig a hole or something.

　　 With the help of construction machinery, it is not difficult to dig an underground shelter that is adequate and capable of defending against natural disasters. In addition, the project undertaken by Chen Xin is a relatively professional engineering team who is using small-scale excavation. The shelter was dug soon under the condition of machine operation, and Chen Xin also transferred all the materials he had hoarded in.

This engineering team is Chen Xin's old relationship, the relationship between the foreman and Chen Xin is quite reliable, and the quality of the project still makes Chen Xin very satisfied.

Because of the high temperature and extreme cold caused by the impact of the meteorite, Chen Xin really wanted to dig the shelter very deep, preferably 50 to 60 meters like a subway station.

　　 But it’s a bit unrealistic. The engineering team can do it, but it takes too much time and the amount of construction. So Chen Xin’s method is to dig a diagonally downward under the mountain near his home. Channel, and then dig a sufficiently large refuge on the basis of the channel.

This is also a common practice of digging air-raid shelters in various countries. Using mountains as shelters can effectively save construction and provide adequate protection for air-raid shelters.

　　 Chen Xin’s refuge is not too big, it adds up to less than 300 square meters, and the garage reserved by Chen Xin, the water tank for storing fresh water and the fuel tank, and other The related equipment and materials and a planting greenhouse used to grow food after the disaster, the usable area that can be used for living is only 30 or 40 square meters.

　　 But for Chen Xin alone, such a large area is more than enough for the possible doomsday.

As for living conditions, Chen Xin's shelter is not a hole in the earth, but after digging a large enough hole, a set of container houses are buried, and these containers are specially customized.

In addition to having good thermal insulation performance, all kinds of living facilities are also readily available, in addition to allowing Chen Xin to stay warm and comfortable even in high temperature and extremely cold environments.

　　In fact, this type of container housing is now very technologically mature. Even when the disease spread at the beginning of the year, the emergency hospitals built by the country used this type of container building.

Compared with the traditional reinforced concrete, this kind of container building can be prefabricated in the workshop, and only needs to be installed when it is transported to the site. Good quality and low price.

　　 However, even so, this whole set of container houses plus the construction cost of the shelters still spent all of Chen Xin’s savings.

　　 But after living in this finally-completed shelter, Chen Xin still feels that he is worth the money.

　　 took a few photos of the completed shelter and sent them to a small survival group drawn between him and his friends~IndoMTL.com~Chen Xin immediately got a look of envy. Before the disaster strikes, he can Preparing for such a well-equipped refuge is enough to greatly enhance Chen Xin's chances of survival when the doomsday comes.

　　 There are even girls in the group who sent messages privately asking Chen Xinque if she does not lack a girlfriend, as long as Chen Xin nodded and asked her to move in, and even if Chen Xin felt that one was not enough, she could bring another girlfriend.

Looking at the two beautiful girls in the photos sent by the girls, Chen Xin could hardly have any intersection, and he almost nodded in agreement.

　　 But Chen Xin still held back. After all, although his conditions are good here, he is a little tight on the stockpiled materials. Although it is not impossible to have two more girls, it will undoubtedly greatly reduce his survival. probability.

After all, according to his estimation, after the disaster, animals and plants will die in a large area, and the source of food is likely to be only rats, cockroaches and mushrooms, which will not disappear even if humans are extinct. These species options. The realization of storage of materials is his only guarantee of survival.

As for growing a greenhouse, it can indeed provide some food, but maintaining a greenhouse requires a lot of resources. For Chen Xin, he is not sure how long the resources he has stored can support the operation of the greenhouse.

　　 Therefore, reducing consumption as much as possible and supporting post-disaster reconstruction after the environment stabilizes is the key to his survival in this disaster.

　　 But despite all possible preparations, Chen Xin still hopes that all his preparations will not be available when things come, and sincerely hope that all countries can resolve this crisis.

　　 can live in the sun after all, who wants to hide in a hole and eat mushrooms?
