"Don't use stones that have been picked up from the riverbed or are very wet. Stones maintain the heat of the flame, help prevent sparks from splashing onto the sleeping pads, and can ensure adequate oxygen circulation under the fire. ”

"To reduce smoke in the house, use wood that is not susceptible to smoke, i.e. dry, without bark or moss, and without resin."

Bi Fang explained while carefully building the fire kang, the inside is the fire kang, and on the outside, he is also ready to extend out to make a suggested stove.

By the time the cabin was completely completed, it was already three days later, and although it took a lot of time and effort, it was worth it in terms of results.

In the cold Arctic snowfield, a small, but unusually neat cabin appeared in the woods.

Each log was straight, giving the house a square look, and a thin layer of frost had accumulated on the sloping roof, but no thicker layer of snow had accumulated due to the slope.

On the other side of the wooden house, a stove made of stones stands out, with a faint gray smoke at the bottom, and a layer of black ash at the bottom, which is the dregs of the burning peat.

Bi Fang opened the door and yawned.

Last night was definitely the most comfortable night he slept on, even the bed was warm.

Burning a fire underneath, separated by a thick layer of rocks, and then covering a soft and thick, clean musk cowhide sleeping bag without peculiar smell, is simply the pinnacle of life.

That's right, musk cowhide was made into a sleeping bag by Bi Fang, and it is said to be a sleeping bag, but in fact, the edges are folded in half and sewn with bark rope.

Since there was no daylight, Bi Fang couldn't tell the time, and because his biological clock was out of order, he didn't know what time he slept until it was.

But judging from the barrage of viewers in the live broadcast room, it should be around ten o'clock in the morning in Greenland.

Thinking of this, Bi Fang picked up his own small horse, which he made himself, covered with a thick layer of musk cow leather, which was taken from the leg of the musk ox, and it was very comfortable to sit on and fish, warm and very soft at the same time.

"Comfort~"

Bi Fang couldn't help but say.

The gray-brown wooden houses were covered with a thin layer of snow, and the small stove beside it was still bubbling with extinguished embers, and the meandering glacier flowed out of the cracks in the low mountains, flowing into the invisible distance, and beyond, endless ice fields, and the dark night emitted a lilac light.

The Arctic is undoubtedly beautiful, but this beauty can only be fully enjoyed when there is no danger to life, and Bi Fang at this time is undoubtedly enjoyed.

"Hah, I'm hooked!"

Bi Fang lifted the fishing rod, and the delicious live fish kept struggling, he pulled the bone hook out of the fish's lip, walked a few steps, and threw the live fish into a puddle, where he could see the other three fish that had also been caught.

Until noon and twelve days, Bi Fang looked at the sky in the distance, and the sun never rose again, nor did he have any daylight.

Eternal night through and through.

Bi Fang breathed a long sigh of relief: "It seems that we won't see daylight until the end of the live broadcast after today." ”

[I've never seen the polar night in my life]

[To be honest, the polar night in the North Pole is brighter than I thought]

[Indeed, and it's purple, why is this]

"When sunlight hits the atmosphere, it is scattered when it encounters atmospheric molecules and particles suspended in the atmosphere. These atmospheric molecules and particles do not emit light on their own, but because they scatter sunlight, each atmospheric molecule forms a scattered light source. ”

"According to Rayleigh's scattering law, light in the solar spectrum with shorter wavelengths such as violet, blue, and cyan is most easily scattered, while colors such as red, orange, and yellow with longer wavelengths are very transmitted. So the clear sky is always blue, and the blue light is emitted in all directions. ”

"It's the same with purple, it has the shortest wavelength, and there's so much snow and dust in the Arctic sky, so it's easy to show up when it's scattered, and we'll see a purple night."

Bi Fang explained briefly, quickly lifted the fishing rod in his hand, and another big fish was caught by him.

[I feel that Fang Shen has no problem surviving for a hundred days]

[yes, I think so too]

[Fang Shen is awesome! 】

"That maybe, we can't sit back and eat, one musk ox is definitely not enough, and the energy intake of all lean meat is definitely not enough in the Arctic, at most a month, and we need salt, and we have to go to the shore, because I have just finished building a wooden house, and I am only going to rest for two days."

"Wait a minute, I'm going to make a dog sled with the rest of the wood, take it to fetch some seawater, extract sea salt, and see if I can harvest some more prey, these three guys, eat so much meat from me every day, it's time to work."

Thinking of the amount of food that the three fools ate Bi Fang, he was not angry, and he was fooling around in the woods all day long, doing nothing, but he ate a lot.

It's just that the three fools ate too much, and Bi Fang had to come out and take fishing as a rest activity.

It's time for them to know what it means to work in exchange for pay.

Three sled dogs are more than enough to pull a hundred kilograms of things, after all, eight can pull three hundred kilograms of goods, run thirty or forty kilometers a day, and bring a person and some portable things more than enough.

And these three are very large, although I don't know how long I have been hungry, but they are still unexpectedly strong, and it is definitely okay to take myself to fetch sea salt.

Thinking that he was galloping on the snowfield with the three fools, Bi Fang was a little moved, and immediately stuffed the big fish he had just harvested into the pit, selected the suitable wood, and after a while, knocked on the pile of wood again, and put the selected long branches on the fire to tann.

In order to carry as much stuff as possible, the weight of the sled had to be small, so it was best to make it with strong branches and make it hollow.

Therefore, the appearance will look like a recliner woven of bamboo strips.

"Dog sleds have always been a lifeline for the North and South poles, transporting medicines and supplies, but now that airplanes and snowmobiles are widespread, dog sledding has become more of a sport, mostly used by locals."

Place the two tanned long sleds on the ground, polish them with stones, and polish all the burrs quickly, which can effectively reduce the resistance and let the three fools pull more things.

After grinding, Bi Fang dug out a chute, and then added a curved guardrail in the front, stuck the guardrail with the groove on the warp head, and then tied it with a rope, which can avoid jamming to the greatest extent and become more sleek.

"I plan to use a mortise and tenon structure for the whole sled, but because of the tool, the processing accuracy is very limited, so I can only use it, which may not be firm, so I have to add glue and fix it with a rope, so it is a little safer."
