In the dark cave, Bi Fang's face was half-lit. Even though there was more than one meter of snow, the audience in front of the screen could still hear the clear howling of the wind, which was quite strange.
It's not like digging a snow cave to take shelter, it's more like being buried alive.
If your mental endurance is low, you will not be able to stay in this kind of environment.
But if you go out, you will probably die. The environment is already cold, and the snowstorm is more like a large heat extraction machine, leaving no heat on the earth.
The wind and snow that blocked the sky even cut off the sunlight, making it impossible to receive any heat radiation.
[This situation, this situation, is a bit like being buried alive]
[The wind today is very noisy]
Bi Fang leaned against Bai Xue and was removing the string originally used to block the snow bit by bit.
He has built the entire roof in the cave into a semicircle. This is the most stable structure, so these ropes are naturally unnecessary.
Building the entire snow roof into a semicircle is time-consuming and labor-intensive.
Not knowing that a blizzard was coming, Bifang dug a very crude snow ditch. The ropes were used as branches, and the upper "snow quilt" was covered on top. Now it has become an arch, so naturally it is no longer needed.
But just for this complete snow house, Bifang spent most of the day digging. It can be seen that compared to a snow trench that only requires one pit, the snow house is really laborious.
After doing all this, Bi Fang stuck the shovel in the ground and lay down in the snow to rest. Although he had tried his best to avoid sweating, he suddenly stopped and there were still faint beads of sweat on his forehead.
The diameter of the entire cave is about 1.6 meters. It doesn't need to be too big for a single snow house. If it's too big, it won't be able to store heat. This size is just right.
It's just that in a cave of 1.6 meters, it is impossible for a tall man who is over 1.8 meters square to lie down flat. There is no space for him to lie down, and the cave cannot accommodate him if he just lies down.
Fortunately, there is an extra step to put the calf, but it can barely fit in, and it is still a relatively comfortable position.
The entire cave is not completely dark, but with the help of a ten centimeter diameter opening above the head, an extremely dim white light is emitted.
How dim is it? It's probably just before you can see it clearly, but the drone needs to turn on the night mode.
This vent is completely parallel to the air outlet, so there is almost no cold wind flowing in. Instead, the air is continuously converted under pressure, ensuring the air quality in the cave.
“When camping in the snow, wind protection is the most important thing. This is the most dangerous thing in a snowstorm and can easily lead to death. Therefore, when building a shelter in a snow-covered environment in the wild, you must remember that it is always easier to dig down than to build up.
Dig around those big trees or where the universities end up."
"The three major types of snow shelters are adapted to different places. The igloo is suitable for hard and heavy snow. Just like now, blizzards have packed the snow on the ground hard and thick."
"Snowdrift shacks are suitable for building in powdery snow, which is the case before it snows, while snow caves are more suitable for use in emergencies."
Bi Fang leaned in the snow, as if lying on a soft sofa, telling the audience some key points intermittently.
"And ensure air circulation. When the body's heat heats the entire shelter, the surface of the snow will melt slightly, forming a good seal. Therefore, ventilation openings must be left or regular inspections must be made to prevent excessive carbon dioxide in the shelter.
Causing poisoning."
Although dry powdery snow cannot be held, if the pressure is strong enough, or the surface receives heat and melts slightly, the snow will crystallize and become half snow and half ice.
Many people have seen this happen, but never noticed it.
That is, after a heavy snowfall, there will often be sunny days, but stepping on the snow at this time has a completely different feeling. When you step on it at this time, you will make a clear and crisp sound, which is different from the quiet sound when it is snowing.
Silence is completely different.
In fact, the surface snow melts slightly after receiving sunlight, and then recrystallizes at low temperatures to form a layer of ice crystals, but it is very thin, and it makes a crunching sound when you step on it.
"Ha~~~"
Bi Fang took off his gloves and took a breath of hot air. He could finally feel some warmth. Because of the movement just now, the entire cave was full of heat. The temperature of the cave was about minus ten degrees to minus five degrees.
But after another half hour, it may stabilize at about minus ten degrees. Although it still sounds very cold, at least it is a warm paradise compared to the low temperature hell outside which may be minus fifty degrees.
【Are we going to wait completely now? 】
[I think something has been done]
[Perhaps we could have done something at the beginning, but now that the wind and snow are raging, it is completely too late]
The water friends' British dialogue is well-organized and makes people laugh when they think about it.
Bi Fang held the rope in his hand, shook the ice chips on it, and sighed as he felt his growling belly.
If the snowstorm really persists for three days, I'm afraid I won't lose ten pounds if I keep waiting.
Leaving aside eating and drinking in a cave, it is really hard to survive in the wilderness. Surviving in the wilderness is not just about having excellent survival skills, these little things are equally important.
Although there is nothing to eat in the past few days, and there is no demand for the large size for the time being, the small size is unavoidable, because water is always drunk. In the past few days, Bi Fang tried his best to solve these needs at once during the day when the sun was shining.
Drop it to avoid the temperature being too low at night and accidentally freezing it.
It's not impossible. If the temperature exceeds 30 degrees, it is possible to pour water into ice.
That's too bad, even the skin will die quickly when exposed to the air, let alone the fragile little brothers.
But there is no solution to this, we can only endure it.
It is impossible to wait for such external weather. Not counting the moss that I ate yesterday, I will be really hungry for a week. I am afraid that I will be too weak to even walk, and I will undoubtedly fall into a vicious cycle.
The only option now was to go out in the snow and wind to see if I could find something to eat around.
"We have to go out and search to see if we can find food, otherwise we can only wait to die here."
The audience was shocked by Bi Fang's decision, but felt it was reasonable.
Bi Fang stuck the dagger on the ground, tied a long rope around his ankle, and tied the other end tightly around the handle of the knife.
"There is too much wind and snow outside, and the visibility is less than five meters. Once you go out, you are likely to get lost in the blizzard. In this case, it is useless to mark, because the traces of the marks will soon be washed away by the wind and snow, and you must use a rope
Only then can I find my way back, but this also limits my movements."
