The glow sticks glow orange and illuminate the small space beneath the tarp.

At this moment, the drone is aside, Chen Ya can only lie flat on the dry grass, and when he looks up, he can touch the tarp, and it is difficult to turn over, let alone sit up.

The army-green tarpaulin can isolate the cold air, in addition, Chen Ya also hugged Tu Feiyuan in his arms and wrapped it in a wool blanket, otherwise the withered grass would be a little prickly.

Such a small space also made netizens roll a barrage.

"Juggernaut chat: I'll go! This space is too small, right?"

"Willow Spirit: It's a bit like a single bed, and I can't sit up yet. ”

"He Laoshi: No, no, no! It should be said that it is like a green coffin, and it feels very depressing!"

"Sui A Feng: It's really a little depressing, doesn't the anchor feel dull?"

"Traveling in a plane: what's boring? If you stay outside, you're going to freeze to death!"

"Montenegro Zhiqiu: That's right, it's good to have a shelter now!"

......

Coffin?

When Chen Ya saw the barrage, he immediately rolled his eyes, and then said:

"Although the space is small, a little oppressive and dull, for me, it means safety. ”

After tens of millions of years of evolution, human beings have become accustomed to living indoors, so a small space, although dull, can still bring a sense of security.

This is the same reason as hiding under the covers in the middle of winter.

Especially now......

Chen Ya opened his mouth to speak, and white gas erupted from his mouth, and the outdoor temperature displayed on his mobile phone had reached minus 3 degrees Celsius.

It is clear that the temperature is dropping dramatically.

And Chen Ya, who was hiding in the pit at the bottom of the pot, blocked most of the cold air through a tarpaulin, and his body was also wrapped in a thick woolen blanket, and the soil in his arms was like a small warm pot.

Even if there was no fire, Chen Ya didn't feel cold, but as time went by, the temperature at night would definitely be even colder.

Time: 21:09

Outside temperature: -8°C

Only half an hour later, the outside temperature dropped by five degrees again, and Chen Ya was not sleepy at all, because he knew in his heart that tonight's low temperature had just begun.

Really......

In the following hour, Chen Ya kneaded the soil in his arms, chatting with netizens in the live broadcast room from time to time, and the outdoor temperature dropped rapidly, soon approaching minus 20 degrees Celsius.

Time: 22:03

Outside temperature: -19°C

Woo!~

And at this moment, outside the pit at the bottom of the pot, there was a whining cold wind, and just listening to the sound made people feel a chill coming.

Even though Chen Ya hid under the tarp and was wrapped in a woolen blanket, he was still a little cold and couldn't stand it, so he immediately spoke:

"No, I'll have to get into my sleeping bag. ”

After speaking, Chen Ya shuddered, quickly opened the sleeping bag, and got into it very carefully to avoid the excessive range of movements, which would make the tarp notched.

At this time, the netizens in the live broadcast room did not feel depressed, but a small space that could make people feel safe.

Soon......

Chen Ya got into the sleeping bag, tarp + wool blanket + sleeping bag, and Tu Feiyuan warmed his body, and finally felt much better.

After all, there is no fire to radiate heat, the human body must rely on its own body to warm clothes, you know, the cold equipment used now is to keep warm, not to let the heat loss.

And Chen Ya, who got into the sleeping bag and only showed his head, couldn't help but fantasize about the fire, if he could drink another cup of hot water, it would be perfect.

Of course!

Listening to the cold wind blowing outside, Chen Ya couldn't help but make up his mind:

"Tomorrow, we must dry the cow dung, which is the most important thing at the moment. ”

As soon as this remark came out, it was immediately approved by netizens, and after Chen Ya finished speaking, he quietly listened to the whistling sound of the cold wind until the outdoor temperature exceeded minus 20 degrees.

Under the illumination of the glow stick, Chen Ya's eyes looked at the tarp above his head, and sure enough, there were some water droplets, so he smiled and quickly took out the military kettle.

But I saw that Chen Ya unscrewed the lid and began to collect water droplets on the tarp, and said at the same time:

"In a closed or confined environment, when the outdoor temperature drops, and the difference between the indoor temperature and the indoor temperature is more than 16 degrees, thermal condensate ...... will occur."

To put it simply, because of the large temperature difference, the water molecules in the air will form hot condensate, which is the same as the vegetables grown in greenhouses.

If you look closely, you will find that there are many fine water droplets hanging in the plastic greenhouse.

Affected by the temperature difference, the water molecules form water droplets, which collect under the tarp, somewhat similar to distilled water, but the problem is ...... Where do water molecules come from?

These water molecules come from the ground, from Chen Ya, and even from the soil.

As long as it contains water, it will inevitably flow slowly, for example, when Chen Ya speaks, the white gas coming out of his mouth is actually water molecules with heat.

After listening to this explanation, netizens suddenly realized that no wonder they drank all the kettle before, it turned out that Brother Ya planned to use this method to collect fresh water.

"No, there will be more condensate than hot condensate!"

Chen Ya shook his head and said, stretched out his hand and knocked on the tarp, and sure enough, he made a sudden sound, and even felt a little heavy, and then smiled:

"Outside the tarp, it's icing. ”

Obviously, the low temperature outside gradually froze the tarpaulin, and even showed that the condensate had turned into ice, which meant that Chen Ya would have more fresh water tomorrow morning.

Hearing this, netizens became even more excited, no wonder Brother Ya would exchange for a tarp, while Chen Ya smiled and continued to use the kettle to collect water droplets under the tarp.

Half an hour later......

Chen Ya stretched out his sleeping bag with his arms, and after half an hour of busy work, he collected a small amount of fresh water, barely enough to drink two or three sips, so he shook his head and said:

"Tomorrow morning, we'll go out again. ”

After speaking, Chen Ya tightened the lid, quickly withdrew his arm, and hugged the soil fat round in his arms.

Chirping!~

His cold hands immediately made Tu Feiyuan open his mouth to protest, Chen Ya smiled, but immediately, he couldn't laugh.

Whew!~~

At this time, Chen Ya faintly heard a wolf howl, and his pupils immediately shrank, while the netizens in the live broadcast room were frightened, and various barrages quickly appeared.

"Turning into a love fish: it! Was it a wolf howling just now?"

"I wish you the wind: there are wolves on the Qinghai-Tibet Plateau, but listening to the sound, I feel that it is far away. ”

"Thomas with the wind: Afraid of hair, except for wolves, our brother Ya is not false at all!"

"Brain-dead: That's right, donkey-headed wolves can kill them, and you're still afraid of wild wolves?"

"Lan Yibing: It's better to be careful, it's not a good thing to have wolves!"

"Uncle Pink: Can you know what kind of wolf it is?"

......

Seeing the barrage, Chen Ya couldn't help but shake his head and said:

"Rest assured, the wolf howl is far away from us, and ...... There are only two species of wolves on the Tibetan Plateau. ”

Then, in the orange light, Chen Ya spoke briefly.

It has been said before that there are only two kinds of wolves in Tibet, the first is the alpine wolf, which looks like a jackal and is not very large, and the second is the snowy plateau wolf, which is a bit awesome.

But no matter how awesome it is, Chen Ya will not be afraid, unless it is a wolf pack, he really doesn't care about two or three plateau wolves.

After all, when he was in Shennongjia, Chen Ya killed two donkey-headed wolves, which was the living ancestor of the wolf, the highest-level existence.

Of course!

The wolf howl also aroused Chen Ya's vigilance, and it seemed that the sound was still in the northwest direction, which was where the snow-capped mountain was located.

At this moment, after Chen Ya briefly introduced the two kinds of wolves, he said with a serious expression:

"For me, the most dangerous beast on the Tibetan Plateau is not a wolf, but a bear!"

This is the most dangerous creature on the plateau, because of his homework, Chen Ya clearly knows that there are only two kinds of bears on the Qinghai-Tibet Plateau, namely the big black bear and the little brown bear.

In terms of numbers, there are many black bears and few brown bears, among which the large black bear has five or six hundred kilograms, which is equivalent to the size of a medium yak.

But black bears have a gentle temperament, and as long as they don't provoke them, they won't take the initiative to attack humans.

Turn......

The little brown bear is dangerous, although the size is slightly inferior, but the temper is very hot, more aggressive, as long as you see a human, most of them bared their teeth, puffed out their shoulders, and rushed over!

This guy is the 'Tibetan Horse Bear' that often appears, also known as the Tibetan Brown Bear, a ferocious one!

Chen Ya only hopes that in the next ten days, he will not encounter Tibetan brown bears, otherwise he will ...... It's indispensable to fight to the death.

That's it......

In Chen Ya's story, time passed quickly, and soon it was early in the morning, officially entering the extremely cold night.

Time: 00:12

Outside temperature: -31°C

Whew!~

At this moment, the cold wind was howling outside the pit at the bottom of the pot, and Chen Ya, who was hiding under the tarp, was still shivering with cold even if he got into the sleeping bag.

At this time, the water droplets hanging inside the tarp all formed frost, and it was obvious that the temperature of the shelter was also below zero.

Chen Ya, who was trembling, hugged the soil fat round in his arms, which was the only source of warmth that he could feel, and then forcibly cheered up his spirits and said:

"It's early in the morning, everyone rest early, let's ...... See you tomorrow morning. ”

After speaking, in the barrage of farewell from countless netizens, Chen Ya withdrew from the live broadcast room, and then breathed a sigh of relief and fought with the low temperature alone.

Tonight......

The biting cold made Chen Ya sleepy, so he could only choose to resist hard, and he didn't even dare to sleep, because he was worried that he would never wake up tomorrow if he fell asleep.

But no matter what, tonight is definitely unforgettable for Chen Ya!

But this ......

And that's just the beginning!

......
