Live Wilderness Adventure

Chapter 657 What a coincidence

People who wonder why the igloo won't melt even when warmed by a fire, in essence, still have too little understanding of the concept of cold.

Most people find it difficult to understand how it feels to turn on the air conditioner at the highest temperature and fully power it in winter, but still freeze people to death indoors.

But many northerners can.

What can't be done with modern air conditioners, how can a fire for only one person be able to do it?

"The insulation of the ice is so good that the outside and inside are completely different temperatures, so the ice and snow on the inner surface will indeed melt, but under the subsequent cold air, it will freeze again and become ice. So lighting a bonfire in the cave, not only doesn't melt the igloo, it makes it harder."

Bi Fang shook his body, explained briefly, and continued to plow the snow.

The environment is dim, and although the sky cannot be seen, it can be judged that it is night. Bi Fang must be extra careful to avoid snowflakes falling into his shoes. In such extreme cold, getting wet shoes is fatal.

Bushes to make a fire are easy to find, but edible food is not.

Before the snowstorm came, the shrubs were all exposed on the ground, and they were easy to see. After just a few glances yesterday, Bi Fang memorized the locations of all the shrubs with his powerful memory.

Although the distance was blurred by the heavy snow, if you explore more, you can always find it.

But things like moss and lichen were buried under the snow layer before the blizzard, and there was no place for Bi Fangji, so he could only search by luck.

As soon as I touched it, I touched it for nearly twenty minutes.

In the blizzard, staying even for a minute is a huge test of physical strength. Bi Fang's limbs have already started to become stiff. If he hadn't been exercising all the time, he might not be able to move long ago.

Fortunately, after digging for nearly five or six meters, a touch of green finally appeared on the screen.

Most of the tundra plants are perennial evergreen plants, which can make full use of the short vegetative period without taking time to grow new leaves and complete the entire life cycle, but the short vegetative period makes the tundra plants grow very slowly.

Although there are not many mosses and lichens in front of him, Bi Fang still regards them as treasures. These are good things that can save lives.

Bi Fang was so energetic that he dug up all of them, regardless of whether the leaves were young or not, and brought them back, even if they couldn't be eaten, they could be used to warm the fire.

In a world of ice and snow, plants are the most precious resources.

Alone, Bi Fang staggered forward in the ice and snow. He was cold and hungry, and his hands and feet were almost on the verge of losing consciousness. Fortunately, his brain was still clear and he would not have hallucinations. An hour after leaving the cave, he dug the second lichen Bi Fang couldn't hold on any longer.

Lifting his legs that were frozen like popsicles, he followed the rope back into the hole.

"hiss."

Bi Fang shook off all the snowflakes on his body, and every muscle wailed and shivered under the severe cold.

The previously stored fat has been consumed in large quantities. Although the whole person does not look obviously thinner, the change in body weight is still something that Bi Fang can perceive.

Of course, it is impossible for ordinary people to lose weight directly without eating for three days, but in the Arctic, this situation may occur.

In the cruel test of minus 50 degrees Celsius given to Bi Fang by nature, his life was all based on the fat all over his body, and his previous weight did not increase in vain.

In the cave, Bi Fang took off his shoes. Although he was very careful, the snowflakes in the storm penetrated everywhere. Although his toes were completely frozen, he could still see that the socks were wet after the snow melted. Digging snow may face the risk of necrosis.

Under excessive cold, limb necrosis, especially toes, is very common even in modern times.

After eating or something, Bi Fang now has to build a campfire to dry his shoes, otherwise it will completely freeze his feet.

Taking all the dry branches and hay out of the backpack, Bi Fang selected suitable materials and simply drilled wood to make fire.

"There is no shortage of fuel in such an environment. There are actually large forests in Greenland, but we don't have them here. There are only shrubs, but they are also good materials. And they are very dry."

"Don't look at these dead branches and leaves as if they are buried in the snow and will become very humid, but in fact there is very little water in them."

"This is a simple physical phenomenon. When it snows, the temperature is low. When the temperature is low, the saturated vapor pressure of the air is low, so the air can carry very little water vapor. When dry air touches wet objects, it will make The water inside the object evaporates more and becomes drier."

[No wonder I always feel that my skin is so dry in winter]

[Except for SpongeBob SquarePants. There's no way it's going to get wet. 】

[Dry climate in autumn and winter is the mainstream of global climate]

Bi Fang took off the gloves, he had to succeed once, because his kung fu hands were already frozen for a while.

He didn't have any fire tools on him, so he could only use the most primitive way of drilling fire, and even because of limited materials, he could only use wood drilling to make fire.

A tool is simply formed by scraping a twig into velvet with a knife.

With Bi Fang's current master-level experience, although his fingers are a little stiff, he actually relies more on his palms to rub the drill and the strength of his arms to successfully ignite the black smoke just once.

The bonfire was lit, and Bi Fang put his hand close to the flame, and his blood immediately became active.

Putting the shoes on the fire and roasting them slightly, Bi Fang put them on again. An indescribable sense of comfort ran up the spine, making people want to stretch.

Bi Fang wanted to change to a more comfortable position, so he leaned against the wall of the cave, and suddenly, the snow fell.

The fire went out.

Um?

Bi Fang raised his head in surprise, only to find that a thick piece of snow had fallen off the top of the originally arched snow roof at some point, like the white wall skin falling from the ceiling that had been in disrepair.

The sudden accident stunned everyone.

There was even a full minute of silence before Bi Fang's voice sounded again.

"This is the consequence of digging first and then rebuilding."

If it is a normal construction of a snow house, it is natural to use snow bricks, and build thick snow bricks one by one, but Bi Fang’s method is to dig a big hole, and then paste the top into an arch shape.

The products produced by this kind of engineering are naturally not as strong and stable as those stacked piece by piece, and it is normal for one or two pieces to fall off occasionally.

Perhaps just under the change of temperature, there has been a slight deformation and detachment, coupled with a slight vibration, it is a coincidence that the fire has just been ignited by smashing it out.

Bi Fang had to start the fire again. This was the last chance, because his hands were no longer in control, and his toes even started to feel tingling. He put on gloves and beat his thigh desperately until his hands regained consciousness. .
