Doomsday Bunker Upgrade

　　 "Dididi...dididi..." The time-fixed cell phone rang on time, waking up Chen Xin who was still sleeping.

　　 reached out and grabbed the phone and glanced at the time on it. Chen Xin put the phone back on the bedside table, and after yawning, he rubbed his face and sat up from the bed.

　　 picked up the clothes on the bedside, and just put a shirt on him, Chen Xin suddenly felt a chill passing from the clothes to him.

　　 Shivered by the chill, Chen Xin hurriedly retracted into the bed.

　　 Wrapped in the quilt and warmed up the clothes with the remaining warmth in the quilt, Chen Xin poked his head out of the quilt, thinking about what happened today, it will become so cold.

　　 Now is not before. If it suddenly became so cold in the morning before the disaster, it is probably due to a cold current. It is not uncommon for the temperature to drop more than ten degrees overnight in autumn and winter.

　　 And the heat preservation effect of ordinary houses in the south is the same. The outside temperature drops by more than ten degrees, and the house will drop by at least three to five degrees or more when there is no heating. It is normal to get cold in the morning.

　　 But now is the end of the world, and Chen Xin lives in a shelter with good warmth, so it shouldn’t be so cold.

　　 Could it be a problem with the ventilation system to keep warm? Chen Xin passed this thought in his mind, but quickly dispelled it.

Although it feels cold now, it’s just because he didn’t wear much clothes, and he just got out of the warm bed and put on clothes with a relatively low temperature. In fact, the temperature is not unacceptably cold. Degree, at least there are still a few degrees.

　　 If there is a problem with the warmth of the ventilation pipe, which causes the external cold air to flow in directly, the temperature will be at least below zero.

　　 In that case, what Chen Xin felt was not cold but ice.

　　 And he only covered a camel hair quilt last night. Although it keeps warm, it hasn't reached the point where a quilt can withstand freezing temperatures.

　　 Facing this strange situation, Chen Xin didn't think about it anymore, and quickly put on the clothes next to him one by one, and crawled out of the bed.

　　 After putting on the clothes, although the temperature before the clothes was a bit low, Chen Xin felt that he was still sitting on hemp and cold, but he was not too unbearable.

　　 Especially after Chen Xin turned over the sweater and trousers that had been in the closet and put it on, it didn't feel cold anymore.

　　Because of the shelter’s thermal insulation ability, even if the outside temperature drops below zero, there are still more than ten degrees in the shelter. As long as he wears a thicker coat and works at ordinary times, Chen Xin does not feel cold.

　　 But the sudden temperature drop today caught him by surprise.

　　 If it were before the disaster, Chen Xin would have touched the phone to check the weather forecast before he was out of bed, but now he can only look at the thermometer hung on the wall in the living room after brushing his teeth and washing his face.

　　 "Seven degrees? The temperature dropped six degrees in one night, isn't it that scary?" Chen Xin couldn't help feeling surprised when he watched the temperature on the thermometer had fallen to single digits.

I’m in the refuge, not mentioning the surrounding reinforced concrete walls and the insulation measures made inside. The ground temperature brought by the two hundred meters high earth mountain above my head will not keep the temperature of the refuge overnight. Drop so much!

　　 Chen Xin was very surprised, he didn't even care about breakfast, so he left the living room and went to the public space, planning to check the ventilation system.

　　 However, looking at the ventilation system that was still functioning well, and the cool breeze blowing from the ventilation system, Chen Xin couldn't help but touch his face. He already understood what was going on.

　　 Chen Xin didn't think too much. This is not a problem with the ventilation system, nor is there something wrong with the insulation of the shelter. Unless he upgrades the ventilation system again or upgrades the shelter as a whole, this problem will not be solved.

Back in the bedroom, I found a temperature measuring gun. After checking that it was still usable, Chen Xinyou touched a large tool hammer from the workbench. Then he came to the maintenance room and changed into protective clothing. After putting on the protective mask, he took the flashlight and climbed through the passage in the tunnel to the small bunker where the communication antenna was placed.

　　 As soon as he opened the door, a gust of cold wind came on the surface, instantly causing a layer of ice to form on Chen Xin's protective mask.

　　 Looking at the ice flower on the protective mask in front of him, Chen Xin stretched out his hand and touched it. When he saw it couldn't be wiped off, he didn't care about it. Anyway, it didn't affect his sight much.

Turning on the flashlight, Chen Xin scanned the inside of the small bunker. As he expected, a layer of ice had formed near the vent, and the gap between the small bunker and the outside world was even more covered. The thick layer of ice almost smeared the entire gap.

　　 walking to the edge of the gap with the hammer, Chen Xin raised his hand and knocked it hard.

　　 Fortunately, the ice layer is not very thick. Although it is strong, it can be broken with a few taps.

　　 As Chen Xin smashed the ice covering the gap, more cold wind was poured into UU Reading www.uukanshu.com.

　　 Chen Xin raised the temperature measuring gun in his hand and pointed it towards the gap in the small bunker that was pouring cold wind into it. The temperature displayed was -34°C.

"Isn't it? Didn't it still have minus 4 degrees yesterday? It dropped by 30 degrees in one night?" Chen Xin was a little bit incredulous. The cooling was really horrible. Something similar to the moment when it entered the ice in the "The Day After Day" movie. The horror of the times.

However, if the temperature is reduced by 30 degrees overnight, it is indeed similar to the effect shown in "The Day After Tomorrow". After all, the ice age will be 8-12 degrees lower than the normal temperature before the disaster, and it is not as cold as it is now .

　　 It's just that Chen Xin couldn't help but worry about another problem.

Before the disaster, the blue star’s climate was actually abnormal. At that time, scientists said that because the environment was destroyed, and the solar activity cycle entered a minimum period, the heat irradiated on the blue star weakened and the blue star was about to enter. A little ice age.

　　 It’s just that this has always been a statement. The Little Ice Age that scientists wanted to talk about has never come, even though the time scientists predicted is within thirty years.

　　 But now that Blue Star is in this situation, it is very likely to directly enter the ice age, or it is already an ice age.

　　 If we enter the ice age, it is expected that the extreme cold and long nights of a hundred years may take longer.

Human beings are creatures that need a warm environment to survive. Although we have extended our activities to severely cold areas through construction, clothing, heating, etc., this does not mean that humans can face low temperatures of tens of degrees below zero. Long-term survival.

　　 Even for polar scientific expeditions, it is difficult to spend a long time outdoors, and most of the time I stay in scientific expedition stations.
