Doomsday Bunker Upgrade

Early in the morning, when Chen Xin finished washing up and took the elevator to the observation room on the upper floor of the shelter, brothers Han Ping and Han Ze were cooking a pot of thick hot soup around the stove, and the aroma of food wafted in the air. , the heat from the stove also slightly dissipated the cold in the room.

"Good morning, Han Ping and Han Ze, did you sleep cold last night?" Chen Xin felt the temperature in the room and asked the Han brothers who were wearing makeshift exoskeleton protective suits.

"Mr. Chen." Seeing Chen Xin coming in, Han Ping hurriedly pulled his younger brother aside, stood up and greeted Chen Xin: "It's okay, it can be tolerated in the room at night, that is, you must put the The heating of the clothes is turned on, otherwise it can't stand it."

Hearing what Han Ping said, Chen Xin motioned for the two to sit down and then glanced at the observation window that had been blocked by glass in the observation room, shook his head and said helplessly: "It's good if you can bear it, no, you can go down at night. Go to sleep. It's too cold, and no one's coming here in bad weather like this."

However, Han Ping still shook his head and said: "The more the weather is like this, the more vigilant it is. People who can still come out in this kind of weather are either vicious or unable to survive. They are all dangerous and must be vigilant."

In the face of Han Ping's attitude, Chen Xin couldn't say anything about him, but he complained about the sudden snowstorm in his heart.

Not long after Li Tou and Ding Ning had been there, a blizzard suddenly blew that night, and the temperature plummeted again. And with winds that can overturn ordinary cars.

There was no sign of the arrival of the blizzard, as if it blew up in an instant, and it swept over everything before anyone could react.

Chen Xin can understand the appearance of this kind of weather. After losing the protection of vegetation and the regulation of atmospheric circulation, the weather system on the entire surface of the earth has completely collapsed. One of the effects of a system crash.

In the past, the cold wave in the winter would cause a large-scale cooling in the Yan Kingdom. Now that the weather system has collapsed, the cold brought by this blizzard will also affect many places. What is different from the past is that the temperature once Once it's down, it's hard to recover.

Because sunlight, the main source of heat on the surface of the blue star, has been blocked by dust, even if the blizzard dissipates, it is still very difficult for the temperature to rise.

At this time, the strong wind of more than 12 level outside the shelter was whizzing by, rolling up countless goose feathers and heavy snow. If there was still sunshine, the sky and the earth would be seen as white.

However, the snowflakes floating in the sky at this time are not ice crystals, but carbon dioxide snow formed by the liquefaction and condensation of carbon dioxide in the air at low temperature, which is commonly referred to as dry ice.

The extreme low temperature has obviously broken through the limit of most buildings to resist the cold. Even Chen Xin's upgraded shelter here can't stand it, so Chen Xin has to turn on the heating system in the shelter to the maximum power. It can ensure the indoor temperature and the survival of plants in the greenhouse.

This also made Chen Xin aware of a problem with the ground source heat pump as a heating equipment, it is affected by the formation temperature, and the temperature rise has a limit.

Although his shelter is deep underground, there is no problem at present, but if the blizzard continues and the temperature cannot rise again, the deep layer may not have any effect, but the shallow layer will definitely reduce the temperature.

This will undoubtedly affect the ground source heat pump equipment that mainly relies on the temperature of the shallow formation to obtain heat, reducing the heating effect.

So if the temperature continues to drop, Chen Xin must consider other heating methods in the shelter.

And now, the temperature in the upper observation room on the surface is as low as minus 20 degrees. This is the result of the fact that Han Ping and Han Ze have been keeping the stove in the room.

It was because of such a low temperature that Chen Xin wanted to let the two brothers go to the lower level of the shelter. It was so cold up there that he was a little worried that the two brothers couldn't stand it.

But Han Ping insisted on staying on top, and has been doing night vigil work with his younger brother.

Chen Xin, who couldn't be persuaded, could only let Han Ping take his younger brother to stay on the upper floor of the shelter, but for safety's sake, Chen Xin still prepared a stove and two sets of protective suits that were urgently made to prevent them from being in the shelter. Frostbite in low temperature environment.

With the protective clothing, Han Ping and Han Ze actually felt that the temperature was acceptable. After all, they were wrapped in an electric blanket. In addition, there was a stove to cook something hot at any time to supplement their body heat, except for the night watch. Other than that it was a bit difficult at times, it was actually fine.

However, Han Ping was still a little worried and asked Chen Xin: "Mr. Chen, our conditions are so good here and it is so cold, so is it colder in other places?"

"Other places? If the cold protection is not done well, I am afraid it is not just a colder problem, it will freeze people to death." When Han Ping asked this question, Chen Xin couldn't help shaking his head.

The temperature of minus forty degrees in the Yan Kingdom can still be encountered in the north, but the temperature of minus seventy degrees is already very extreme.

At this temperature, the scene in the movie "The Day After Tomorrow" that directly freezes the helicopter flying in the sky will really appear.

The polar temperature makes it difficult to even raise a fire. Even if there are buildings that can withstand the cold wind, if there is no heat source, the temperature drop is enough to freeze all life.

The urban area relies on coal-fired boilers for heating. It should still work normally in this weather, but most of the shelters in the urban area are not the type that goes deep into the ground, and most of the cold protection and heat preservation are before the disaster. It was temporarily remodeled for three months, which inevitably made Chen Xin very worried about the situation in the urban area.

But in this environment, even Chen Xin didn't dare to go out. The snowstorm outside was enough to put any vehicle in a desperate situation. Even his modified crawler RV could hardly guarantee nothing in this environment.

Maybe only the heavy-duty vehicle in "The Wandering Earth" can handle such a harsh climate?

Chen Xin thought so in his heart, and the attitude that had become more comfortable because of the better living conditions also became tense again, and he felt the crisis of survival.

Although Chen Xin himself can live without worry now, it is not that he really does not have an existential crisis.

After the weather system collapses, extreme weather is terrible, and the minus 120-degree snowstorm in "Frozen Age" is not impossible.
