"Didi-di-di-di-di-di..." The phone that had been set at the time rang on time, waking up Chen Xin who was still sleeping.
Chen Xin reached out to grab the phone and glanced at the time on it. Chen Xin put the phone back on the bedside table. After yawning, he rubbed his face and sat up from his bed.
Picking up the clothes on the bedside and just putting a shirt on, Chen Xin suddenly felt a chill passing from the clothes to his body.
Shivering at the coolness, Chen Xin hurriedly retreated back into bed.
After wrapping himself in a quilt and using the remaining warmth in the quilt to warm up his clothes, Chen Xin poked his head out of the quilt and thought about what was going on today that made it so cold.
This is not the same as before. If it suddenly became so cold in the morning before the disaster, it was probably due to a cold wave. It is not uncommon for the temperature to drop by more than ten degrees overnight in autumn and winter.
Moreover, the thermal insulation effect of ordinary houses in the south is just that. The outside temperature drops by more than ten degrees, and the temperature inside the house will drop by at least three to five degrees or even more without heating. It is normal to wake up cold in the morning.
But it's the end of the world now, and Chen Xin lives in a shelter with good thermal insulation effect. Logically speaking, it shouldn't be so cold.
Is there something wrong with the ventilation system? This thought flashed through Chen Xin's mind, but he quickly gave it up.
Although he feels cold now, it's just because he doesn't have many clothes on, and he has just climbed out of the warm bed and put on clothes with a relatively low temperature. In fact, the temperature is not unbearably cold. To a certain extent, at least there are still a few degrees.
If there is a problem with the insulation of the ventilation ducts, causing cold wind from outside to flow in directly, the temperature will be at least below zero.
In that case, what Chen Xin felt would not be cold but ice.
Moreover, he was only covered with a camel hair quilt last night. Although the thermal insulation effect was good, it was not to the extent that a quilt could withstand freezing temperatures.
Faced with this strange situation, Chen Xin stopped thinking about it, quickly put on the clothes next to him one by one, and climbed out of the bed.
After putting on his clothes, although Chen Xin still felt numb and cold because the temperature before the clothes was a little low, it was not to the point of being unbearable.
Especially after Chen Xin took out all the sweaters and cotton pants that he had kept in the closet and put them on, he no longer felt the cold.
Previously, due to the shelter's thermal insulation capabilities, even if the outside temperature dropped below zero, it would still be more than ten degrees Celsius inside the shelter. As long as he wore a thicker coat and had to work regularly, Chen Xin didn't feel cold.
But today's sudden temperature drop caught him off guard.
If it was before the disaster, Chen Xin would have been reading the weather forecast on his phone 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 by six degrees in one night. It's not that scary, right?" Chen Xin couldn't help but feel surprised when he saw that the temperature on the thermometer had dropped to single digits.
I am in a shelter. Not to mention the surrounding reinforced concrete walls and the insulation measures inside, even the ground temperature insulation brought by the more than 200 meters high earth mountain above my head will not reduce the temperature of the shelter overnight. It’s dropped so much!
Chen Xin felt so strange that he didn't even bother to eat breakfast, so he left the living room and came to the public space, intending to check the ventilation system.
However, looking at the ventilation system that was still running well and the obviously 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 much about it. This was not a problem with the ventilation system or the insulation of the shelter. Unless he upgraded the ventilation system again or upgraded the shelter as a whole, this problem would not be solved.
After returning to the bedroom, he pulled out a thermometer gun. After checking that it was still usable, Chen Xinyou took out a large tool hammer from the workbench, then went to the maintenance room and put on protective clothing. 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 he opened the door, a gust of cold wind came over the face, instantly causing a layer of ice to form on Chen Xin's protective mask.
Looking at the ice flowers 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 caring about it. It didn't affect his vision much anyway.
Turning on the flashlight, Chen Xin glanced around the inside of the small bunker. Sure enough, as he expected, a layer of ice had formed near the vents, and the gap connecting the small bunker to the outside world was even covered with ice. There was a thick layer of ice, almost covering the entire gap.
Carrying the hammer, Chen Xin walked to the gap, raised his hand and knocked hard on it.
Fortunately, the ice layer is not frozen very thick. Although it is quite strong, it can still be broken after a few hits.
And as Chen Xin broke the ice sealing the gap, more cold wind 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? Wasn't it -4 degrees below zero yesterday? Did it drop to 30 degrees overnight?" Chen Xin couldn't believe it. This drop in temperature was really terrifying, a bit like the moment he entered the glacier in the movie "The Day After Tomorrow" The times are terrifying.
However, if the temperature drops by 30 degrees overnight, it will indeed be similar to the effect shown in "The Day After Tomorrow". After all, the Ice Age was only 8-12°C lower than the normal temperature before the disaster, and it was not as cold as it is now. .
But Chen Xin couldn't help but worry about another problem.
Before the disaster, the climate of the Blue Star was actually somewhat abnormal. At that time, scientists said that it was because the environment was destroyed and the solar activity cycle entered a minimum period. The heat shining 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 just a statement. The Little Ice Age that scientists want to talk about has never arrived, although scientists predicted that the time would be within thirty years.
But the current situation of Blue Star is very likely to directly enter the Ice Age, or it is already an Ice Age now.
If we enter an ice age, it is expected that the hundreds of years of extremely cold nights may last even longer.
Humans are creatures that need a warm environment to survive. Although we have expanded our scope of activities to severely cold areas through construction, clothing, heating, etc., this does not mean that humans can face temperatures as low as tens of degrees below zero. Long-term survival.
Even for polar scientific expeditions, it is difficult to spend time outdoors for long periods of time. Most of the time, they stay at the scientific research station. (End of chapter)
