Live Wilderness Adventure - Chapter 654 good luck

People who wonder why the fire in the igloo doesn't melt, essentially, they know too little about the concept of cold.

It is difficult for most people to understand what it feels like to turn on the air conditioner to the highest temperature in winter, and the power is full, but the room can still freeze to death.

But many northerners can.

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

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

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

The environment was dark, and although he couldn't see the sky, he could still tell that it was night. Bi Fang had to be extra careful to prevent snowflakes from falling into his shoes. In such extreme cold, it would be fatal to get wet shoes.

Fire bushes are easy to find, but edible food is hard to find.

Before the wind and snow came, the bushes were all exposed on the ground, and it was easy to see them. Just after a few glances yesterday, Bi Fang had memorized the locations of all the bushes with his strong memory.

Although Daxuemo Lake is far away, you can always find it by exploring more.

But things like moss and lichens, I bought under the snow before the blizzard came, and there was no place for Bi Fangji, so I could only search by luck.

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

In the blizzard, even staying for a minute is a huge test of physical strength. Bi Fang's limbs have begun to become stiff. If he hadn't been exercising, he would have been unable to move.

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

Tundra plants are mostly perennial evergreen plants that can make full use of the short vegetative period without having to spend time growing new leaves and completing the entire life cycle, but the short vegetative period makes tundra plants grow very slowly.

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

Bi Fang was in high spirits and dug them all up. No matter what young leaves were not young, he brought them back and said that they can be used for roasting even if they cannot be eaten.

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

The solitary Bi Fang staggered forward in the ice and snow, 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 up a second lichen. Bi Fang couldn't hold on any longer.

He lifted his legs that were frozen like popsicles, and drilled back into the hole along the rope.

"hiss."

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

The previously stored fat was consumed in a large amount. Although the whole person did not seem to lose weight, the change in body weight was still noticeable to Bi Fang himself.

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

In the cruel test of minus fifty degrees given by nature to Bi Fang, his life was all pinned on the fat of 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 snow in the storm was all-pervasive. Although his toes were completely frozen, he could still see that the socks were wet after the snow melted. When digging snow, you may face the risk of necrosis.

Excessive cold, necrosis of limbs, especially the toes, is a very common thing even in modern times.

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

Taking the dry branches and hay out of the backpack, Bi Fang picked out the right materials for a simple fire drill.

"There is no shortage of fuel in such an environment. Greenland actually has a large forest, but we don't have it here. There are only shrubs, but it is also a good material. And it is very dry."

"Don't look at these dead branches and leaves that seem to be buried in the snow and become very wet, but in fact they have very little moisture."

"This is a simple physical phenomenon. When it snows, the temperature is low, and 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 comes into contact with wet objects, it will make The moisture inside the object evaporates more and becomes dry."

[Except SpongeBob SquarePants. Can't get wet with water. 】

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

Bi Fang took off his gloves, unbuttoned his jacket and took out a match. He had to succeed at once, because his kung fu hand was frozen for a while.

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

A simple tool is formed by scraping a branch into a velvety shape with a knife.

Based on Bi Fang's current master-level experience, although the fingers are a little stiff, the drill actually relies more on the palm of the drill and the strength of the arm, and the black smoke is successfully ignited only once.

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

He put the shoes on the fire and lightly roasted them, and Bi Fang put them on his feet again. An indescribable feeling of comfort jumped up along the vertebrae of the Heavenly Spirit Cover, which made people want to stretch.

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

The fire is out.

Um?

Bi Fang raised his head in surprise, but found that the top of the arched snow roof had shed a thick piece of snow at some point, like a white wall that fell from the ceiling in disrepair.

The sudden accident stunned everyone.

After being silent for a full minute, Bi Fang's voice sounded again.

"The consequences of digging first and then rebuilding are like this."

If the snow house is to be built normally, it is natural to use snow bricks, and build the thick snow bricks one by one, but Bi Fang's method is to dig a large hole and then arch the top lake.

The ones made by this kind of engineering are naturally not as strong and stable as the pieces stacked together, and it is normal for one or two pieces to fall off occasionally.

Perhaps it was just under the change of temperature, which had undergone a slight deformation and detachment, and coupled with a slight vibration, the fire just ignited by coincidence.

Bi Fang had to start the fire again, this was his last chance, because his hands were no longer able to obey, his toes even started to tingle, he put on gloves and hit his thighs desperately until his hands felt again. .
