Who knows! As soon as I returned to the mountains to farm, I encountered a natural disaster.

Mu Xi nodded, with a serious look on his face: "I saw it...but my watch stopped moving when I went out just now."

"broken?"

Mu Xi shook his head: "No, when I bought it, it was said that this watch can withstand the lowest temperature of minus 65 degrees."

Zhao Yeqing opened his mouth silently, and the two of them looked at each other for a moment without saying anything.

In other words, the temperature outside must be below minus 65 degrees now.

It dropped from minus 50 degrees to below minus 65 degrees in three days...

No wonder the floor doesn't feel warm today. I have to wear a thick coat in the house.

"Can the watch still work? Is it just that it can't be used outside, or is it frozen?"

This thing is very precious. If it gets frozen, you won't even be able to see the temperature.

Mu Xi raised his hand and took a look: "Fortunately, it seems that the watch just can't be moved outside. It's my fault, I didn't expect it when I went out. It's below zero now indoors, and it must be much colder outside."

Zhao Yeqing shook his head: "No one expected such a low temperature. No southerner should have any idea about minus 60 degrees Celsius."

Then I thought about it, it’s more than minus 60 degrees in the south. Isn’t it possible that the north has touched the threshold of minus 100 degrees?

It’s scary to think about it.

Zhao Yeqing gathered his coat and pulled away the little black guy whose tail was too close to the fire and was about to fall into the stove.

"Don't get so close. Your fever will be gone soon and you will get even colder."

Mu Xi looked around the room and said, "The curtains around this room are no longer good. There are gaps in them that are not properly sealed. If the room can be made smaller, the floor heating will work."

It's not a built-up wall, so the sealing is definitely not enough. There will inevitably be gaps between the curtain fabrics.

If you want to keep it airtight, you have to find some airtight materials to cover or fill the gaps.

But the material of the curtains is soft after all, and it would be difficult to completely block and fill it with hard materials. The soft materials at home are airtight, and there seems to be nothing except the plastic film.

But the plastic film cloth is a bit thin, but the thermal insulation effect is pretty good. However, if this thing is combined with the curtains, it must be cut into a long strip and connected to the top of the curtains.

Once the tape is cut, it cannot be recycled and reused. When the greenhouse is needed, it will be troublesome if it is gone. This thing cannot be recycled.

Mu Xi suddenly remembered the large canvas of the yurt from before, "Didn't a small piece of the canvas from the collapsed yurt be cut off to shade the grapes? Half of such a large piece of cloth would be enough to split the house in two. "

If he hadn't said it, Zhao Yeqing would have almost forgotten about the piece of cloth. It was a good idea. The canvas was waterproof, so heat preservation would definitely not be a problem, and the thickness was sufficient.

"Is it a little heavy?"

The fabric that can be used as the outer building material of a house is definitely not light and thin. The accessory they use to support the current curtains is a Roman rod, and the gap is the top of the rod and the round hole through which the curtain passes.

Now, if you directly replace the curtains with canvas, you will definitely not be able to use Roman rods. Not only will there still be gaps, but they will also break.

The best way is to nail it directly to the ceiling. I wanted to do this with the curtains before, but the length was not enough, and the longest curtain in the entire tourist area was not long enough. The two of them were lazy and could have cut another curtain to lengthen it. After a while, I finally decided not to do it because it was too troublesome.

Who could have imagined that the temperature would be so low.

The temperature in the room has dropped to more than ten degrees below zero, and this is even with the floor heating on.

Mu Xi put on two thick coats before walking out of the house. Zhao Yeqing stood by the window and watched, fearing that he would accidentally slip and fall in the snow and be too cold to get up.

After the canvas was brought back, the two of them measured the length and began to cut it. After Zhao Yeqing drew the cutting lines on the cloth, he put his hands together to his mouth, breathed a sigh of relief, and quickly rubbed it to generate heat.

Mu Xi took the scissors and cut along the marked part. Seeing that her hands were cold and red, he said: "No need to help now, you can go to the fire first and I will do it. My body temperature is relatively high and I am not so afraid of the cold."

The location where the canvas is cut is in the front half of the house. This half does not have floor heating. Fortunately, there is not much space to place things, so the canvas can be spread out slightly here.

Zhao Yeqing didn't show any pretense, he threw the marked stone on the table and ran to the fire to warm himself up.

At this temperature, the gel pens at home could no longer produce water, so Zhao Yeqing used two talc ores that Mu Xi found while digging limestone to draw lines.

Zhao Yeqing removed the straw mat on the floor and sat directly on the ground, so that he could feel the slightest bit of heat coming up.

Now I have to go out to feed the livestock every day, and then run back to warm myself by the fire. I am so hot and cold without catching a cold. I have to say that my physical fitness has really improved a lot.

I used to work in the city, and I would catch a cold when I came back from outside to blow on the air conditioner in the summer. This winter has been here for so long, except for a little runny nose at the beginning, the two of them have never gotten sick once.

Otherwise, the environment trains people.

Zhao Yeqing warmed himself up by the fire and recalled the news and documentaries he had seen before. Before the Earth Split, there were many countries and regions with extremely low temperatures in winter. He remembered that there were two cities in Russia that could not see the sun for several months a year. It can get as cold as minus 70 degrees.

In the Xing'an Mountains in the north, temperatures can drop to more than 50 degrees below zero in winter.

Not to mention Siberia, which is notoriously cold.

People there will still go out for activities when the temperature reaches minus 60 or 70 degrees Celsius, and they won’t say that they will be unbearably cold as soon as they go out.

Zhao Yeqing comforted himself: It's okay, he can survive if he adapts.

Maybe after a while, if they continue to exercise in this weather, they will be able to swim in winter swimming in weather that is dozens of degrees below zero like the people of the fighting nation.

The constant hints calmed down her anxious mood. She didn't want to be anxious, but the sun hadn't risen for a long time.

In areas suffering from polar nights, many people there suffer from winter depression because they cannot see the sun.

Without sunlight, the body will suffer from vitamin D deficiency and endocrine disorders. Coupled with the long-term darkness and desolate scenery outside, the whole world feels cold and gloomy, and gradually suffers from mental illness. The suicide rate during that period was also the highest. .

But no matter what, there will be light in the polar night, there are stars and the moon, it's not like they are so dark that there is no light at all.

Coupled with the harsh changes in the environment, there are wild beasts watching eagerly outside, and I can't even go out for a simple trip. I am stuck in the house all day, and I really can't get through it without adjusting myself.

Fortunately, there is still someone around to talk to, otherwise in these few months in winter, no matter how cheerful a person is, he will become depressed.

Thinking of this, Zhao Yeqing poured himself another cup of hot milk with enough sugar in it.

At this time, sweets are the best medicine.
