    In the early morning, when Chen Xin finished washing and took the elevator to the observation room on the upper floor of the shelter, the two 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 coldness in the house.

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

    "Mr. Chen." When Han Ping saw Chen Xin coming in, he hurriedly pulled his brother aside, stood up and greeted Chen Xin: "It's okay. The room is still bearable at night, but it must be kept during the night watch.  Turn on the heating of your clothes, otherwise you won¡¯t be able to bear it.¡±

    After hearing what Han Ping said, Chen Xin motioned for the two of them to sit down and then glanced at the observation window of the observation room that was blocked by glass. He shook his head and said helplessly: "As long as you can bear it, you can go down at night if you can't."  Go to sleep. It¡¯s too cold, and no one will come here in this bad weather.¡±

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

    Faced with Han Ping's attitude, Chen Xin couldn't say anything to him, but he complained in his heart about the snowstorm that came without warning.

    Shortly after Li Tou and Ding Ning arrived, a blizzard suddenly blew that night, and the temperature dropped sharply again. From the originally tolerable minus 30 degrees, it suddenly fell below minus 70 degrees.  And it's accompanied by strong winds that can blow over an ordinary car.

    The blizzard arrived without any warning, as if it blew up in an instant and swept everything before people could react.

    Chen Xin can understand the occurrence of this kind of weather. After losing the protection of vegetation and the regulation of atmospheric circulation, the weather system on the entire earth's surface has completely collapsed. The wind has lost its resistance and has become more violent. The appearance of extreme weather is just weather.  One of the effects of system crash.

    In the past, the cold wave in winter would cause widespread cooling across the country. Now that the weather system has collapsed, the cold brought by this snowstorm will also affect many places, and what is different from the past is that once the temperature  Once it falls, it is difficult to recover.

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

    At this time, strong winds exceeding level 12 were howling outside the shelter, rolling up countless amounts of heavy snow. If there was still sun, you would be able to see the sky and the earth being completely white.

    But 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 temperatures, which is commonly known as dry ice.

    The extreme low temperature has obviously exceeded the limit of most buildings to withstand the cold. Even Chen Xin's upgraded shelter could not withstand it, so Chen Xin had 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 ground source heat pumps as heating equipment. It is affected by the ground temperature and has a limit to the temperature rise.

    Although there are currently no problems with his shelter because it is deep underground, if the blizzard continues and the temperature cannot rise for a long time, the deep layer may not have any impact, but the shallow layer will definitely reduce the temperature.

    This will undoubtedly affect the ground source heat pump equipment, which mainly relies on the temperature of the shallow strata to obtain heat, and reduce the heating effect.

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

    Now, the temperature in the upper observation room on the surface has dropped to more than 20 degrees below zero. This is the result of Han Ping and Han Ze keeping the stove on in the room.

    It was precisely 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 too cold up there, and he was a little worried that the two brothers couldn't bear it.

    But Han Ping insisted on staying up there and kept vigil with his brother.

    Unable to persuade Chen Xin, he could only let Han Ping and his brother stay on the upper floor of the shelter. However, for safety reasons, Chen Xin still prepared a stove and two sets of emergency protective clothing for them to prevent them from being trapped in the shelter.  Frostbite and frostbite in low temperature environments.

    With protective clothing, the two brothers Han Ping and Han Ze actually feel that the temperature is quite bearable.After all, it was like having an electric blanket wrapped around me, and there was also a stove that could cook something hot at any time to replenish body heat. Except for the fact that the night watch was a bit difficult, it was actually fine.

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

    "Other places? If the cold protection and warmth are not done well, it may not only be a problem of getting colder, but also freezing to death." When Han Ping asked this question, Chen Xin couldn't help but shook his head.

    Temperatures of more than 40 degrees below zero can still be encountered in Yanguo in the north, but temperatures of more than 70 degrees below zero are already very extreme.

    Under this kind of temperature, the scene in the movie "The Day After Tomorrow" where the helicopter flying in the sky freezes to the ground will really happen.

    The temperature in the polar regions makes it difficult to even start 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 to death.

    The urban area relies on coal-fired boilers for heating, which should still work normally in this weather. However, most of the urban shelters are not the type that go deep underground, and most of the cold protection and insulation were installed before the disaster.  It was temporarily renovated in three months, which inevitably made Chen Xin worried about the situation in the city.

    ¡°But in this environment, even Chen Xin did not dare to go out. The snowstorm outside was enough to put any vehicle into dire straits. Even his modified crawler car could not guarantee that nothing would happen in this environment.

    Maybe only the heavy-duty carrier vehicles in "The Wandering Earth" can cope with such a harsh climate, right?

    With this thought in Chen Xin's mind, his attitude that had become comfortable due to the improvement of living conditions became tense again, and he felt the crisis of survival.

    Although Chen Xin can now live without worries about food and clothing, it does not mean that he does not have an existential crisis anymore.  (Remember the website address: www.hlnovel.com
