In the next tens or even hundreds of years after the meteorite impact, there will be no sunlight on the surface of the blue star, and the temperature will be as low as minus tens of degrees.

And in the case of a shortage of supplies, cold clothing, food to fill the stomach, fuel to keep warm, shelters to live in, these will become sought-after things, killing people for a little food...... This is nothing new.

Even before the meteorite fell, millions of people died of starvation every year on the Blue Star.

In those war-torn countries where food is scarce, in order to be able to fill their stomachs, people can be turned into food, let alone just killing people and stealing food?

If it weren't for the fact that Yuan Da Druid made hybrid rice to ensure food production and make the vast majority of people in the country have enough to eat, in fact, it would have been as distressed as other countries in the world because of food problems.

The food problem is a global problem, and as the world loses sunlight and gradually cools, there is no hope for global food production.

And after losing the original food output, the vast majority of the world's countries will be in a food crisis, and people will soon starve to death.

Because a considerable number of countries in the world have not solved the problem of eating, they usually rely on imports for food, and now there is no one to provide them with food.

In such a situation, the more populous the place, the faster the depletion of the reserves, and the materials that may exist in the outside world become the sought-after things.

No one can have too many things to ensure their survival, but they want to get them......

In the apocalyptic world without the constraints of morality and the rule of law, it is really who has the biggest fist and who makes sense.

In fact, what to eat in the coming days is a difficult problem for all mankind, and without the food in the fields, it is impossible for mankind to survive by relying on the materials in reserve.

The good shelters that the state has built should have a certain amount of reserve materials to be able to resume production to a certain extent, after all, Chen Xin himself has built a planting greenhouse in the shelter, and he does not believe that the country does not have this ability.

However, the only amount that can be provided by growing greenhouses is very scarce vegetables and fruits, and it is unrealistic to grow food in large areas of greenhouses.

At least in the first few years of the disaster, it was not realistic or cost-effective to build a large-scale greenhouse growing system.

You must know that although hybrid rice has a high yield, it is still rice, and planting consumes a lot of water resources, and in the apocalyptic world, the low temperature of dozens of degrees below zero, obtaining enough water resources is a huge problem in itself.

In fact, the state does not plan to build large-scale greenhouses to grow food, according to the official information released by the state to ensure the food supply of the shelters in the future, the state will adopt the method of growing mushrooms and raising rats to ensure food supply in the future.

Compared with traditional crops that require sunlight and consume a lot of fresh water to grow, mushrooms are obviously much easier to raise, as long as the temperature of about 18-20 degrees can be guaranteed in the darkroom, and then the culture material is good, and the environment is kept in a humid state, it can meet the growth conditions of mushrooms.

Although mushrooms are not as delicious as vegetables and fruits, edible mushrooms are rich in fat, protein, sugar, dietary fiber and various vitamins, which can meet the survival needs of the human body.

As for raising rats, it is a better way to obtain meat resources than raising other poultry and livestock, after all, everyone understands the vitality of rats, and this thing can be fed with a little food.

As long as the feeding environment is clean and the subsequent processing is hygienic, a stable meat resource can be obtained.

But even if there are two ways to ensure food supply, supplies will still be strained.

After all, when the state built shelters before, it only equipped these things in the main shelters in major cities, and some shelters renovated with underground civil air defense facilities in residential areas may not have time to be equipped with these facilities.

And even if there were, it would take some time to scale, and in the early days of the apocalyptic world, most of the Vaults would probably still have to rely on the supplies they had stockpiled in advance to survive.

But...... Material reserves are limited.

As the end came, the state did build a lot of shelters, and managed to get most people to take refuge in shelters, avoiding the loss of their lives in the first wave of disasters caused by meteorite impacts.

But this also brings with it another problem, which is that more people means more material consumption.

Survival inevitably consumes food and water, and social problems arise as a result.

The various disasters caused by the meteorite impact will destroy most of the original communication facilities on the surface of the blue star, and the level of human communication is likely to return to the era of telegraph and wired telephone, and mobile phones and wireless communication are basically obsolete.

Communication is not smooth, and everyone stays in a closed and relatively independent environment like a shelter, and each shelter is far away, and it is predictable to form its own small circle.

Until the state regains control over the country, chaos and the exposure of some of the dark sides of human nature cannot be stopped.

It is impossible to say when the state will be able to resume production and construction and rebuild social order, and if the most extreme situation occurs, the danger to the outside world will skyrocket.

It's like the rescue team in "The Wandering Earth", they are equipped with exoskeleton armor and heavy firepower to carry out rescue missions on the surface, and their firepower is not used to break glass.

In this case, if Chen Xin does not have the ability to protect himself, and the shelter does not have a certain ability to resist foreign enemies, then everything he has now is likely to become a piece of fat in the eyes of others.

For Chen Xin, the first 30 years of his life were peaceful years, living in the safest country in the world, and he never worried about his own security.

But now that the end is coming, he has to worry about it.

Fortunately, in the past, when I played outdoor survival, I had to face some possible dangers, and Chen Xinshou still had some things that could deal with dangers.

A katana, a recurve bow, and two daggers, these things will undoubtedly be confiscated by the police uncle when they are taken out in peacetime, but as a tool for survival in the wild or as a tool for self-defense in this apocalyptic era, these things can bring Chen Xin a great sense of security.

Especially when Chen Xin found that these weapons in the cabinet, together with the cabinet, could be upgraded as a whole, his sense of security was even more sufficient.
