Doomsday Bunker Upgrade

　　 entertained Mo Qingyan and Ding Ning for a meal in their refuge, and Chen Xin sent them away.

　　 After the two left, Chen Xin's shelter was quiet again.

　　 The freezer was turned on, debugged to confirm that it started working, and Chen Xin put the previously harvested vegetables in and refrigerated them at low temperature to ensure that these vegetables would not spoil.

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

Although I don’t usually drink alcohol, in the end of the world, having a drink before going to bed can actually soothe my nerves and make myself sleep more soundly, so this time Chen Xin deliberately asked Mo Qingyan for a change. Box of wine.

　　More importantly, these things will become extremely rare with the arrival of the end times. After all, wine requires food. When people are not full, there is no extra food to use for wine.

　　These wines from before the end of the world will also become rare and precious resources, and will become more valuable as the end of the world lasts longer.

However, Chen Xin did not have the idea of ​​hoarding wine as a material. On the one hand, he has the system in his hand, as long as he continues to upgrade the refuge. When the planting greenhouse has enough output, it is not difficult to make wine. Deliberately to hoard.

　　 On the other hand, I want to wait until the wine becomes very valuable. It takes a long time, and this long time is enough for Chen Xin to have the ability to make wine himself, and the expansion of the planting greenhouse allows the grain output to support his winemaking.

　　 Of course, some of the treasures in the wine cellar of Mo Qingyan's house are still very tempting for Chen Xin. Maybe I can ask her for some good wine in the future?

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

　　 Among the materials exchanged from Mo Qingyan today, what really made Chen Xin think that should be hoarded was canned pork.

　　The end of the world is coming, and the original food output of mankind has basically been reimbursed. Naturally, there is no way to raise poultry and livestock. Meat resources will become very rare, even more than wine to some extent.

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

　　 Even if the country has built underground farms before the end of the world, these things are destined to only become luxury items on the table of a very few people, and will not flow into ordinary refuges, as things that everyone can enjoy before the end of the world.

　　 Although the country did formulate a plan for food for refuge after the end of the world before the end of the world, the taste of mushrooms and mice...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 artificial meat?

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

　　 But for Chen Xin, this made him 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 a state for survival in the last days. Ingesting 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 last days, being able to eat well while being full is obviously able to greatly improve the quality of life in the last days.

　　 It's just that there is a problem here that still bothers Chen Xin a little, and that is where to look for the animal's mother.

　　 The system upgrade may allow the refuge to have the ability to raise animals, but Chen Xin's system function only has the ability to upgrade. He is not sure whether he can randomly attach a few live animals after upgrading the refuge to obtain the ability to raise animals.

　　 If he let him do it himself, it's not easy to see live animals in this environment.

　　 But maybe there will be animals in the big refuge? Not to mention, the two creatures, rats and earthworms, are two of the three important food sources prepared by the country before the end of the world for the end of the world. Together with mushrooms, they plan to provide precious food for humans in the end of the world.

　　 just eat mice and earthworms... This makes Chen Xin feel a little bit responsive, who has not yet entered the state of eating or eating in the last days.

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

As for earthworms, no one really eats this stuff before the end of the world, but the earth is frozen in "Wandering Earth". After human beings enter the underground life, the main source of food is edible earthworms~www.NovelMTL.com~ it is to let earthworms The concept of edible is understood by people.

The current environment of Blue Star is quite different from the environment in "Wandering Earth". After all, everyone faces the same environmental problems, but the current Blue Star is not as extreme as the Wandering Earth. And now humans have not yet lived in a dungeon several kilometers deep below the planetary engine.

These gaps are of course caused by the generational difference in technology between movies and reality. After all, for real humans, digging a hole that is more than a thousand meters deep is the same, but if you want to dig a dungeon that is more than a thousand meters deep ...

　　 This is beyond the limit that humans can do with current technology, and humans don’t really need to dig such a deep hole.

In "Wandering Earth", a dungeon that is so deep is dug because of actual needs. In reality, humans want to avoid the extreme cold in the end of the world. Although digging deep enough, it is a good idea to use the ground temperature for heating. However, existing technology still restricts us from doing so, and it is really unnecessary.

　　 Although mankind’s existing technology can build dungeons, for example, the city of Montreal in the Maple Leaf Country has a 17-kilometer dungeon. The construction time was only in the middle of the 20th century.

But the depth of this dungeon is only the depth of underground buildings 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 in "Wandering Earth". .

　　 In fact, under normal human conditions, it is almost impossible to carry out construction at this depth.

　　Although the underground city of Montreal is not deep, it can withstand the long winter that lasts four or five months and more than 30 degrees below zero each year.
