Doomsday Bunker Upgrade

After entertaining Mo Qingyan and Ding Ning for a meal in his shelter, Chen Xincai sent them away.

After the two left, Chen Xin's refuge became quiet again.

After powering on the freezer and debugging it to confirm that it started working, Chen Xin put the vegetables harvested before, and refrigerated them at low temperature to ensure that these vegetables would not rot.

In addition to vegetables, the canned luncheon meat and canned pork that were exchanged from Mo Qingyan were also put into the storage room by Chen Xin, but the box of wine was moved to his bedroom by him, and he took out a bottle and put it on the bedside table. After that, the rest was stuffed under the bed.

Although I usually don't drink too much, but in the current apocalypse, having a drink before going to bed can relieve nerves and make myself sleep more soundly, so Chen Xin specially asked Mo Qingyan to change it this time. Case of wine.

And more importantly, these things will become extremely rare with the arrival of the end of the world. After all, brewing requires food. When people can't eat enough, they don't have any extra food to brew.

These pre-apocalyptic wines will also become rare and valuable resources, and will become more valuable as the apocalypse continues.

However, Chen Xin has no idea of ​​hoarding wine as a material. On the one hand, he has the system in hand as long as he continues to upgrade the shelter. When the planting greenhouse has enough output, it is not difficult to make wine, and it is not necessary. Deliberately hoarding.

On the other hand, it takes a long time to wait until the wine becomes very valuable, and this long time is enough for Chen Xin to have the ability to make wine, and to expand the planting greenhouse so that the food production can support him to make wine.

Of course, some treasures in Mo Qingyan's wine cellar are still very tempting to Chen Xin. Maybe he can find her for some good wine in the future?

This thought popped into Chen Xin's mind, and he couldn't help but think about this matter, but he didn't think too much about it. This matter is not something that needs to be anxious for a while.

Among the supplies exchanged from Mo Qingyan today, it was canned pork that really made Chen Xin feel that he should hoard.

The end of the world has come, and the original food output of human beings has basically been reimbursed, and the raising of poultry and livestock will naturally be out of the question. Meat resources will become very rare, even more than wine to some extent.

After all, wine can still be brewed by growing food in a greenhouse, but pork, beef...

Even if the country has built underground farms before the apocalypse, these things are destined to only become luxuries on the dining table of very few people, and will not flow into ordinary shelters, like things that everyone can enjoy before the apocalypse.

Although the country did make a plan before the end of the world on what the shelter should rely on to obtain food after the end of the world, the taste of mushrooms and mouse meat... No one would think that these things can be the same as pork and beef.

Of course, with these, maybe you can look forward to the taste of artificially synthesized artificial meat?

After all, if there is demand, there will be a market. In the near future, artificial meat may become popular. The improvement of the taste will make it taste more like meat. It should become a rigid demand.

However, for Chen Xin, this allows him to look forward to whether the function of animal breeding will appear after the planting greenhouse is upgraded.

If the function of animal breeding can be obtained, then perhaps Chen Xin can obtain a stable source of meat.

Although people will not die if they don’t eat meat, malnutrition is not the state of survival in the last days. The intake of animal protein from meat is a necessary factor to maintain human health and balanced nutrition.

Although it is not easy to fill the stomach in the apocalypse, being able to eat well while being full will obviously greatly improve the quality of life of people in the apocalypse.

But there is a problem here that still makes Chen Xin feel a little troubled, that is, where to find the mother of the animal.

The system upgrade may allow the shelter to have the ability to raise animals, but Chen Xin's system only has the ability to upgrade, and he is not sure if he can randomly add a few live animals after upgrading the shelter to obtain the animal raising ability.

If he were to do it himself, it would not be easy to see live animals in this environment.

But there might be animals in the sanctuary? If nothing else, these two creatures, mice and earthworms, are two of the three important sources of food prepared by the country for the apocalypse before the apocalypse. The plan, together with mushrooms, provides valuable rations for the survival of mankind in the apocalypse.

Just eating mice and earthworms... This makes Chen Xin, who has not yet entered the state of eating anything in the last days, feel a little uncomfortable.

Although rat meat is actually a kind of meat that is a bit curious but can be regarded as serious food before the end of the world, as long as the sanitary environment can be controlled, rat meat can indeed be regarded as a good source of animal protein in the end of the world. .

As for earthworms, before the end of the world, no one really eats these things, but in "The Wandering Earth", the earth is frozen. After humans enter the underground life, the main food source is edible earthworms, but the concept that earthworms can eat is popular with people. understood.

Compared with the environment in "The Wandering Earth", the current environment of Blue Star is quite different. After all, the environmental problems faced by everyone are similar, but the current Blue Star has not reached the extreme situation in the Wandering Earth. And today's human beings have not lived in the underground city several kilometers deep below the planetary engine.

These gaps are of course caused by the technological generation gap between movies and reality. After all, for real human beings, digging a thousand-meter-deep hole is almost the same, but if you want to dig a thousand-meter-deep dungeon ...

This is beyond the limits of what humans can do with current technology, and humans don't really need to dig a hole that deep.

In "The Wandering Earth", a dungeon is dug so deep because of practical needs, but in reality, humans want to avoid the extreme cold in the end-time weather. Although they dig deep enough, it is a good idea to use the ground temperature to keep warm. However, existing technology still restricts us from doing so, and it is really unnecessary.

Although the existing technology of human beings can build dungeons, for example, the city of Montreal in the Maple Leaf Country has a dungeon with a length of 17 kilometers. The construction time was only in the middle of the 20th century, and it has been more than half a century.

But the depth of this dungeon is only the depth of the underground building under normal circumstances, which is equivalent to the depth of the current underground pedestrian passage or pedestrian street, and it is not exaggerated to the depth of five kilometers below the surface of the "Wandering Earth". .

In fact, it is almost impossible for humans to carry out construction at such depths under normal circumstances.

Moreover, although the underground city of Montreal is not deep, it can also withstand the long winter of more than minus 30 degrees below zero for four or five months every year.
