Chapter 100

"Diddidi "Diddidi..." Set the time of the mobile phone on time, wake up the still sleeping Chen Xin.

After grabbing the mobile phone and taking a look at the time above, Chen Xin puts the mobile phone back on the bedside table. After yawning, he rubs his face and sits up from the bed.

He picked up the clothes at the head of the bed and just put a shirt on his body. Chen Xin suddenly felt a cool air passing from the clothes to him.

Shivering with this coolness, Chen Xin quickly retracts the quilt.

After wrapping himself in the quilt and warming his clothes with the help of the extra heat in the quilt, Chen Xin poked his head out of the quilt and thought about what happened today. It would be so cold.

Now is not the past. If it is so cold in the morning before the disaster, it is estimated that we have encountered a cold current. It is not uncommon for us to cool down more than ten degrees a night in autumn and winter.

In addition, the thermal insulation effect of ordinary houses in the south is the same thing. The outside temperature drops by more than ten degrees, and the inside temperature drops by at least three or five degrees or more without heating. It's normal to get cold in the morning.

But now it's the end of the world, and Chen's new residence is a shelter with good heat preservation effect, which should not be so cold.

Is there something wrong with the heat preservation of the ventilation system? Chen Xin thought of this idea in his mind, but soon dismissed it.

Although he feels cold now, it's just because he doesn't have many clothes on him. He just climbed out of the warm quilt and put on clothes with low temperature. In fact, the temperature is not so cold that people can't accept it. At least he has a few degrees.

If there is something wrong with the heat preservation of the ventilation pipe, which leads to the direct inflow of cold air from the outside, the temperature will be below zero at least.

In that case, what Chen Xin feels is not cold but ice.

And he only covered a camel hair quilt last night. Although the effect of warmth preservation is good, it is not so good that a quilt can resist the zero temperature.

In the face of this strange situation, Chen Xin didn't think about it any more. He quickly put on the clothes one by one and crawled out of the bed.

After wearing the clothes, although Chen Xin still feels numb and cold because the temperature before the clothes is a little low, he can't stand it.

Especially after Chen Xin turned over all the sweaters and cotton trousers that he had put in the wardrobe, he didn't feel cold.

Previously, because of the shelter's thermal insulation capacity, even if the outside temperature fell below zero, there were still more than ten degrees in the shelter. As long as he wore a thicker coat and had to work at ordinary times, Chen Xin didn't think it would be cold.

But today's sudden drop in temperature caught him off guard.

If it was before the disaster, Chen Xin might have felt his mobile phone to read the weather forecast before he got out of bed, but now he can only brush his teeth and wash his face to see the thermometer hanging on the wall of the living room.

"Seven degrees? The temperature dropped six degrees in one night, isn't it so terrible? " Chen Xin was surprised when he looked at the single digit temperature on the thermometer.

I'm in the shelter. Not to mention the reinforced concrete walls around and the insulation measures inside, even the earth temperature brought by the earth mountain more than 200 meters above my head will not make the temperature of the shelter drop so much in one night!

Chen Xin felt very strange, and even did not care to eat breakfast, so he left the living room and went to the public space, intending to check the ventilation system.

However, looking at the ventilation system that still works well, and the cool air blowing from the ventilation system, Chen Xin can't help touching his face. He already knows what's going on.

Chen Xin didn't think much. It's not the ventilation system or the heat preservation of the shelter. Unless he upgrades the ventilation system again or the shelter as a whole, this problem can't be solved.

Back in the bedroom, he turned out a temperature measuring gun. After checking that it could still be used, Chen Xinyou felt a large tool hammer from the workbench. Then he came to the servicing room and put on protective clothing. After putting on a protective mask, he took a flashlight and climbed to the small cover with communication antenna through the corridor.

As soon as the door was opened, a cold wind came from the shop, which immediately made Chen Xin's protective mask ice.

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

Turning on the flashlight, Chen Xin scanned the inside of a small shelter. As he expected, a layer of ice had formed near the vent, and the gap between the shelter and the outside world was covered with a thick layer of ice, which almost covered the whole gap.

Carrying a hammer to the edge of the gap, Chen Xin raised his hand and knocked hard.

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

As Chen Xin broke the ice that sealed the gap, more cold air poured in.

Chen Xin raised his temperature measuring gun and pointed to the gap of the small bunker filled with cold air. The temperature displayed was - 34 ℃."No? Wasn't there another one at minus four yesterday? 30 degrees in one night? " Chen Xin can't believe it. It's really terrible. It's similar to the horror of the ice age in the movie the day after tomorrow.

However, if the temperature drops by 30 degrees overnight, it will be similar to the effect shown in the day after tomorrow. After all, the ice age is 8-12 ℃ lower than the normal temperature before the disaster, which is not so exaggerated.

But Chen Xin can't help worrying about another problem.

Before the disaster, the climate of the blue star was already abnormal. At that time, scientists said that the blue star was going to enter a little ice age because of the destruction of the environment, the solar activity cycle entered the minimum period, and the heat shining on the blue star weakened.

But this has always been just a statement. The little ice age that scientists want to talk about has never come, even though the time predicted by scientists is within 30 years.

But now the situation of Bluestar is likely to enter the ice age directly, or it is already the ice age.

If we enter the ice age, it is expected that the extremely cold night of a century will last longer.

Human beings need a warm environment to survive. Although we expand our scope of activities to cold areas through construction, clothing, heating and other means, it does not mean that human beings can survive in the low temperature of tens of degrees below zero for a long time.

Even for polar scientific research, it's hard to be outdoors for a long time. Most of the time, they stay in the scientific research station.
