The cold wind howled, An Kai and Mary wore protective suits and walked on the ridge with some difficulty.

　　 There is a problem with the outside air purifier.

　　 is not a big problem, mainly because one of the three purification devices has a problem.

　　 This is a bit uncomfortable. Losing one-third of the oxygen production at once may not matter a day or two, but this problem must be dealt with as soon as possible.

　　 Otherwise, as time goes on, the lack of oxygen is one aspect. He is even more worried that the other two purification devices will also have problems. Then the oxygen may really be cut off. This is the real big problem.

　　 During this time, Ankai has been busy in the underground world. It is either busy expanding planting and breeding, or busy expanding its base and constantly adding various rooms. In fact, since the nuclear explosion, he has basically never been out except for trying out the car a few days ago. Of course this is his own choice, but he has been in the room, and he really can't bear it anymore.

　　 There is a saying, he really wants to lift the mask.

　　Although the air in the sanctuary is purified and has no peculiar smell, it feels a little dull in people's minds, and it always feels that the air has no vitality.

　　 The air outside is the real circulating air, but unfortunately, it is full of radioactive dust. An Kai still wants to live, so this kind of thinking can only be thought of after all.

　　 The light from the outside world has become a little brighter during this period of time.

　　 is no longer the same black as before, but there is a little bit of light. The "cloud" above the head is no longer pitch black, but a little gray part can be seen.

　　 Although the gray part is really only a little bit, but this point shows that the threat of nuclear winter is passing.

In fact, An Kai has seen various novels, movies, or other types of literary works about nuclear winter on the earth. To put it bluntly, they mainly talk about early warning and reflection on nuclear war, mainly for warning. Mankind, don't really break out a nuclear war.

　　The so-called nuclear winter means that when a large number of nuclear weapons are used, especially on flammable targets such as cities, a large amount of smoke and soot will enter the earth’s atmosphere, which may lead to very cold weather.

　　 When a nuclear explosion occurs, huge amounts of energy are injected into the atmosphere, and some of them are as high as 12 kilometers or more into the stratosphere. Since most of the smoke and dust particles produced by nuclear explosions are less than 1 micron in diameter, they can stay at high altitude for several days or even more than a year. Because their average diameter is less than the infrared wavelength (about 10 microns), they are very sensitive to the visible light from the sun. Radiation has a strong absorption power, while the absorption power of infrared light radiation outward from the ground is weak, which causes the upper atmosphere to heat up and the surface temperature to drop, which has the opposite effect to the greenhouse effect, making the ground surface present a landscape like a cold winter , Called nuclear winter.

However, it must be pointed out that the nuclear winter is based on the assumption of the data model. There is no decisive argument for the accuracy of the assumption. Several years or even more than a decade before Ankai’s rebirth, scientists supported the original version. The model of the nuclear winter theory was wrong, and a new model calculation was made. The final result is that the actual nuclear winter only has a temperature drop of 14-20 degrees, and this cooling will only last for a few hours, and it will be 3-4 Return to normal within months.

　　 Of course, this conclusion cannot be said to be correct.

　　 And now the world is different from the earth, so how much the temperature can drop and how long it lasts is still unknown.

　　 Oh, no, the former already has an answer.

　　Before the nuclear explosion, the temperature in nature was about 15 to 20 degrees. After the nuclear explosion, the temperature was inevitably lowered because of the loss of sunlight. At the coldest time, it once reached more than ten degrees below zero. But recently, the temperature is gradually picking up. To put it bluntly, the radiation cloud can block outside temperature, and naturally it can block the temperature emanating from the planet.

　　 is like a big quilt. Wasn't there a situation where you used a bicycle to sell ice cream? It is insulated with quilts.

　　 The high temperature outside cannot enter, and the cold inside cannot dissipate. In fact, the heat is the same.

　　 The human interaction of the planet itself and the operation of the planet itself will create temperature. The radiation cloud blocks these temperatures in the atmosphere. Therefore, after a short period of decline, the temperature will gradually return to a relatively stable level. And because of the difference in high and low temperature, wind and rain began to occur.

　　 Once there is wind and rain, the radiation dust will gradually be diluted and brought back to the ground.

Of course, the fall of radioactive dust does not mean that it is safe. In fact, this kind of scientific name is radioactive falling ash, and its radiation effect can last for several years or even more than ten years. They can only enjoy the sun for a while, and hope to return to nature. The generation of Ankai is estimated to be impossible.

Hai Li and his generation, it is possible in old age, but the possibility is not too great. After all, this is all tens of thousands of nuclear bombs around the world. I don’t know how much radioactive dust is produced. I want to wait for so much radiation. The dust dissipates all its radiation, which is definitely not possible in a short time. Even if mankind has the means to govern, facing such a scale of radiation, I am afraid it is powerless. Having the sun is nothing more than making life better and feeling more comfortable. Want to completely change your life? Let's wash and sleep.

　　 There is really everything in the dream.

　　 So there is no need to think about this kind of thing anymore, but consider how to live better and be more realistic.

　　 The reason why An Kai brought Mary out today is also to let Mary come out for a little activity, feel the outside life, wait for the mountain by the way, and live the two-person world.

　　 It is said that it is dangerous and dangerous, but it is said that it is safe and safe. At least there will be no beasts attacking them. The beasts would have died under the global nuclear explosion long ago.

　　 The air purifier is located at an altitude of more than three hundred meters. It doesn't seem to be high, so it's quite difficult to climb up. But living in the basement every day, An Kai really feels that her whole body is going to rust, and at least her arms and legs can be more comfortable when she comes out for activities. UU reading www. uukanshu.com He dragged Mary and dragged her forward. It took two hours before he came to the air purifier.

　　 This thing can be manufactured from the inside when it is manufactured, but it must be out when it is repaired. In fact, this thing can be upgraded from the perspectives of durability, oxygen production capacity, and oxygen production speed. If the durability is upgraded to a high enough level, it can take a long, long time before it fails. But who made An Kai never promoted him? At present, these three aspects are still the lowest level. It took more than a month to break, which is really very good.

　　 An Kai squatted down, took out the tools, and started beating on the oxygen generator. He doesn't need to repair it, he just needs to bring tools and materials to repair it through the system.

　　 But this location...

　　 "Is it good to get a platform?"

　　 An Kai thought for a while, turned around and said to Mary.

　　 This is right above the shelter. Although it is far away from the elevator shaft, if you open a door on the mountain in the distance and build a path, will you not have to climb the mountain in the future?

　　Climbing a mountain can certainly exercise your body, but if you can save some energy, why not do it?

　　 An Kai began to think about the possibility of this job.

　　Mary looked at him seriously and sighed helplessly. She said so nicely before, but at this time, she still hopes to be lazy and tricky.
