In the dark cave, Bi Fang's face is half light and half dark, even if it is separated by more than a meter of snow, the audience in front of the screen can still hear the clear wind whistling, which is quite weird.

It's not like digging a snow cave to take refuge, it's more like being buried alive.

Psychological endurance is almost there, and this kind of environment can't last.

But going out is mostly death, the environment is already cold, and the blizzard is more like a large heat extractor, leaving no heat on the earth.

The wind and snow that obscured the sky and the sun blocked the sunlight and could not receive any heat radiation at all.

[In this situation, the height is a bit like being buried alive]

[Today's wind is very noisy]

Bi Fang leaned back against the snow and was removing the string that was originally used to keep the snow away.

He had already built the entire roof inside the cave into a semicircle, which was the most stable structure, and these ropes were naturally not needed.

Forming the entire snow roof into a semicircle is time-consuming and labor-intensive.

I didn't know that a snowstorm was coming, but the snow ditch dug by Bi Fang was very simple, and the rope was used to act as a branch, and the upper layer of the "snow quilt" was covered on it, but now it has become an arch, so naturally there is no need for it.

But for this complete snow room, Bi Fang dug for most of the day, which shows that compared to the snow trench that only needs one pit, the snow room is really laborious.

After doing all this, Bi Fang stuck the shovel on the ground and lay down in the snow to rest, although he had avoided sweating as much as possible, but at this time he suddenly stopped, and there were still faint beads of sweat on his forehead.

The diameter of the whole cave is about one meter six, and the single snow room does not need to be too big, it is too big to store heat, and the size is just right at the moment.

It's just a cave of 1.6 meters, Bi Fang is more than 1.8 meters tall, it is impossible to lie flat, there is no space for him to lie down, and this cave will not accommodate him if he lies hard.

Fortunately, there is an extra step for the calf, but it can barely be stuffed, and it is still a more comfortable position.

The entire interior of the cave was not completely dark, but with the help of a ten-centimeter-diameter opening overhead, emitting an extremely dim white light.

To what extent is it dim, probably because Bi can see clearly, but the drone has to turn on the night mode.

This vent is completely parallel to the air vent, and there is almost no cold air pouring in, but it constantly changes the air under the action of pressure, ensuring the air quality in the cave.

"When camping in the snow, the most important thing is to protect yourself from the wind, which is the most dangerous in a snowstorm and can easily lead to death, so when building a shelter in the wild in a snowy environment, you must remember that it is always easier to dig down than to build up, and dig around those big trees or the last place where the university is stacked."

"The three major types of snow shelters are also adapted to different places, and igloos are suitable for hard, heavy snow, just like now, when blizzards crush the snow on the ground hard and thick."

"Snowdrift huts are good for setting up in powdery snow, which was the case before it snowed, while snow caves are better suited for emergencies."

Bi Fang leaned against the snow, as if lying on a soft sofa, and intermittently told the audience some points.

"And to ensure air circulation, when the body's heat heats up the entire dwelling, the surface of the snow melts slightly, creating a good seal, so it is important to leave vents or check regularly to prevent poisoning by excessive carbon dioxide in the shelter."

Although the snow is dry and powdery to hold, if the pressure is high enough, or if the surface receives heat and melts slightly, the snow will crystallize and become half snow and half ice.

Many people have seen this situation, but they have never paid attention to it.

That is, often after a heavy snowfall, there will be a sunny day, but at this time stepping on the snow, the feeling is completely different, at this time, stepping on it, there will be a crisp clattering sound, and the silence when the snow is falling is completely different.

In fact, the snow on the surface melts slightly after receiving sunlight, and then recrystallizes at low temperatures, becoming a layer of ice crystals, but it is very thin, and it will make a clattering sound when you step on it.

"Ha~~~"

Bi Fang took off his gloves and took a breath of heat, and finally felt some warmth, because of the exercise just now, the entire cave was full of heat, and the temperature of the cave was about minus ten degrees to minus five degrees.

But if you wait another half an hour, it may stabilize to about -10 degrees Celsius, and although it still sounds cold, at least compared to the low-temperature hell that may be at minus 50 degrees outside, it is already a warm paradise.

[Is it just a matter of waiting for now?] 】

[I think something has been done]

[Maybe we could have done something at the beginning, but now that the wind and snow are raging, it's completely too late]

The British dialogue of the sailors is clear-eyed, and the thoughts make people laugh.

Bi Fang held the rope in his hand, shook the ice chips on it, felt the gurgling stomach, and sighed.

If the snowstorm really lasts for three days, if you keep waiting, I'm afraid you won't lose ten pounds.

Eating and drinking in the cave aside, Lazar is really too tormented, and survival in the wilderness is not only about having excellent survival skills, but also about these small things.

Although there is nothing to eat these days, there is no need for large ones for the time being, but small ones are inevitable, because the water has always been drinking, and the first few days Bi Fang tried to solve these needs at one time during the day when the sun was in full bloom, so as to avoid the temperature being too low at night and accidentally freezing.

It's not impossible, more than thirty degrees, it's completely possible to splash water into ice.

That's too bad, even skin can die quickly when exposed to air, let alone a fragile little brother.

But there is no solution to this, so we can only endure it.

With such external weather, it is impossible to wait, the moss I ate yesterday does not count, I am really hungry for a week, Bi Fang is afraid that he will be so weak that he can't even walk, and there is no doubt that he will fall into a vicious circle at that time.

The only option now is to brave the wind and snow to go out and see if you can find something to eat in the surrounding area.

"We have to go out and look for it and see if we can find food, or we'll just die here."

The audience was shocked by Bi Fang's decision, but felt that it was reasonable.

Bi Fang stuck the dagger on the ground, tied one part of the long rope to his ankle, and the other end was firmly tied around the hilt.

"The wind and snow outside are too big, the visibility is less than five meters, once you go out, you are likely to get lost in the blizzard, this situation is useless to mark, because the traces of the mark will be quickly washed away by the wind and snow, and I have to use a rope to find my way back, but this also limits my movement."

"Good luck to me."
