Doomsday Bunker Upgrade Chapter 99: Blizzard

"DiDiDi...DiDiDi..." The phone that had set the time 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.

Picking up the clothes on the bed, and just putting a shirt on, Chen Xin suddenly felt a gust of cool air pass from the clothes to him.

Chen Xin hurriedly retracted into the bed again after being shivered by the coolness.

　　 was wrapped in a quilt, and after warming 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 the past. If it suddenly becomes so cold in the morning before the disaster, it is estimated that it has encountered a cold snap. It is not uncommon for the temperature to drop by more than ten degrees in the autumn and winter.

　　 And that’s the same thing about ordinary houses in the south. The outside temperature is reduced 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. matter.

But now it's the end of the world, and Chen Xin lives in a shelter with good thermal insulation. Logically speaking, it shouldn't be so cold.

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

Although he feels cold now, it's just because he doesn't have much clothes on, and he just climbed out of the warm bed and put on clothes that are cooler. In fact, the temperature is not so cold The unacceptable level, at least there are still a few degrees.

　　 If there is a problem with the heat preservation of the ventilation pipe, which causes the cold outside 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.

Moreover, he only covered a camel hair quilt last night. Although the thermal insulation effect is good, it is not yet to the extent that a quilt can withstand the freezing temperature.

Faced with this strange situation, Chen Xin stopped thinking about it, 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 of the clothes was a bit low, Chen Xin felt that he was still sitting on the numb and cold, but it was not to the extent that he could not stand it.

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

Because of the shelter's thermal insulation ability, even if the outside temperature dropped below zero, the temperature inside the shelter would still be more than ten degrees Celsius. As long as he wears a thicker jacket and usually has to work, Chen Xin doesn't feel that it will be cold. .

　　 But the sudden temperature drop today caught him by surprise.

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

"Seven degrees? The temperature dropped six degrees overnight, isn't it so scary?" Chen Xin couldn't help but be surprised when he saw that the temperature on the thermometer had dropped to single digits.

　　 I’m in a refuge, not to mention the surrounding reinforced concrete walls and the insulation measures made inside. The ground temperature and warmth brought by the two hundred meters high earth mountain above the head will not make the refuge. The temperature dropped so much overnight!

Chen Xin was so surprised that he didn't even bother 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 was still working 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 a problem 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.

Returning to the bedroom, he pulled out a thermometer gun. After checking that it was still usable, Chen Xinyou took a large tool hammer from the workbench, and then came to the equipment room to put on protection. After putting on the protective mask, he took the flashlight and climbed through the passage in the corridor to the small bunker where the communication antenna was placed.

As soon as the door was opened, a gust of cold wind came over the surface, instantly making Chen Xin's protective mask form a layer of ice.

Looking at the ice flower on the protective mask in front of him, Chen Xin reached out and touched it. Seeing that it couldn't be wiped off, he didn't care anymore. Anyway, it didn't affect his vision much.

　　 turned on the flashlight, and 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 visible. It was covered with a thick layer of ice, almost covering the entire gap.

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

Fortunately, the ice layer is not frozen very thick. Although it is quite strong, it can still be broken after a few knocks.

And as Chen Xin smashed the ice that sealed the gap ~IndoMTL.com~ more cold air poured in.

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

　　 "Isn’t it? Didn’t there still be minus 4 degrees yesterday? It dropped 30 degrees in one night?" Chen Xin was a little bit incredulous. The cooling was really horrible, something similar to the one in the "The Day After Day" movie. Instantly entered the horror of the Ice Age.

　　 But if the temperature is really reduced by 30 degrees overnight, it is indeed similar to the effect shown in "The Day After Day". After all, the ice age is 8-12 degrees lower than the normal temperature before the disaster, and it is not cold enough. So exaggerated now.

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

　　Before the disaster, the blue star’s climate had already been abnormal. Scientists said at the time that the environment was destroyed and the solar cycle entered a minimum period. The heat irradiated on the blue star was weakened. The star is about to enter a little ice age.

It's just that this has always been just a statement. The Little Ice Age that scientists want to talk about has never come, although scientists predict that the time is within 30 years.

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

If we enter the ice age, then the extreme cold and long nights that are expected to last a hundred years may be longer.

Humans are creatures that need a warm environment to survive. Although we have extended our range of activities to cold areas through construction, clothing, heating and other means, this does not mean that humans can face dozens of minus zeroes. low temperature for long-term survival.

Even if it is a polar scientific expedition, it is difficult to spend a long time outdoors, and most of the time is spent in the scientific research station.
