After taking some time, Bifang arrived at his exclusive cabin and looked at his cabin across the river.
In perfect condition.
There was not much snow accumulated on the sloping roof, only three inches thick, and a pale and ferocious cow skull hung high above the door of the wooden house.
Although a little scary, it adds a wild and lively feel.
【To be honest, this picture is a bit beautiful.】
[Indeed, the ice fields, rivers, wooden houses, and the faint purple starry sky are so beautiful]
[It’s so beautiful, I really want to travel to the North Pole]
[Already booking tickets]
[Where can I buy tickets for the Tesis ferry? I want this]
Some water friends posted comments with emotion, as if they wished they could live in it and be close to nature.
In such an atmosphere, Bi Fang said rather grimly: "There are no modern facilities here, the food is not good, the seasonings are only salt, and you have to be careful to freeze your little brother when you go to the toilet. I don't think most of them can stand it if they live in it."
, Oh, one thing is good, that is, using snowballs as toilet paper, it does feel much better than paper."
[Well, don’t ruin my beautiful fantasy, Hun Dan! 】
[Indeed, without Fang Shen’s ability, most people would not be able to experience comfort at all, and could only feel the feeling of struggling in a desperate environment]
[Woo woo woo, leave some good things for me]
Ignoring the wails of the water friends, Bifang crossed the river and returned to the shelter. Bifang did not rush to find fuel, but first went to the place where he had buried the muskox meat.
After careful inspection, he breathed a sigh of relief after confirming that there were no signs of damage. He smiled at the audience and said, "We're lucky. No small animals broke in during the two days we came out, or we didn't find anything buried here."
Treasure'."
What Bi Fang was most worried about when he went out was undoubtedly the musk oxen buried underground. He was afraid that some animals would dig holes and snatch away the trophies he had worked so hard to obtain.
At that time, I will fall into a passive state again. Although there is still fish and meat as a supplement, I always lack a sense of security in my heart.
After simply taking some meat, Bi Fang changed places and continued to dig the hole. Then he put the excess musk meat back into it and buried it again.
"When digging it out, the excess snow will be mixed together, and there will inevitably be some smell on it, which can be easily discovered by animals, so we have to bury it again to make it safe enough."
After obtaining the food and letting San Sha have a good meal, Bi Fang began to collect fuel.
"The first thing is fuel. Put more peat soil in it. They have a high calorific value."
Bi Fang put the frozen mud bricks into the basket one by one. The frozen bricks were as hard as rocks and were neatly stacked.
The basket is made of woven wooden strips and is cylindrical. After adding mud bricks, there are still many gaps around it, which are filled with hardwood.
"Hardwood burns longer, so you can prepare more. In fact, the best way is to prepare charcoal. The calorific value of charcoal is about 27.21~33.49 megajoules per kilogram, which is higher than ordinary peat soil. But from building a kiln to burning
, it will take at least three hours, so we won’t waste that time.”
This pile of fuel weighs about twelve or three kilograms. If you use it sparingly, it will be enough for three days.
"One kilogram of charcoal can theoretically burn for eight hours. Of course, the Arctic environment will speed up this process, so we need a bunker. Even if the charcoal we have is not charcoal, but peat soil and hardwood, but for three days, it will burn for three hours a day.
It's more than enough for heating or cooking something."
Bi Fang made a simple calculation with the audience and placed the basket on the sled, followed by food and some tools. The total weight was almost the weight of an adult.
After all, there are only three sled dogs, and the weight of two people is already the limit for continuous running. Any more may affect the efficiency.
After preparing his things and clearing the snow on the wooden roof, Bifang drove the sled out of the shelter and returned to the Tesis.
Under the night sky, the Tethis was fighting tenaciously against the ice. The most surprising thing was that the expedition ship was slowly falling to one side, causing the audience to scream wildly.
【Holy shit, shit, shit, what’s going on, what’s going on????】
【Is it going to fall? Is it going to fall?】
【Why did the ship suddenly sink????】
【Ruined!!!】
"Don't be surprised, this is normal operation."
Bi Fang's tone was very calm, and he was not alarmed by the tilt of the Tesis.
You call this normal operation!?
The sailors stared at the extremely tilted Tesis with expressions of disbelief on their faces.
"Of course, to put it simply, icebreakers use the downward pressure of the ship's bow to break ice. There are generally three methods of icebreaking, namely continuous, collision and swing."
"When encountering an ice layer no more than 1.5 meters thick, the icebreaker will use the continuous icebreaking method, using the power of the propeller to first climb the hull on the ice, and then slap it downwards to smash the ice layer. However,
The driving force of the propeller is not insignificant, it runs like a knife and can chop ice cubes in minutes."
"When the thickness of the ice exceeds 1.5 meters, the collision ice breaking method must be used. First, use the bow of the ship to crush the thick ice into pieces, then retreat a certain distance and then sprint forward. At this time, the momentum
It is enough to knock the broken ice away, and use the power of the hull to hit it repeatedly to open up a new channel."
"When the Tesis first appeared, it used a direct collision method. Because it was close to the coast, the ice surface was very thin, and it could even be said that part of it was ice floes. It could only advance more than a hundred meters at a time. After that, it would not be so
It’s easier.”
"Although such a violent ice-breaking method not only has low ice-breaking efficiency, it also causes huge damage to the hull itself and requires regular maintenance. Therefore, new ship ice-breaking structures are still being studied. However, no matter how foolproof the ice-breaking method is, it will also encounter special circumstances.
, such as being stuck by the ice, etc.”
“In the past, when European icebreakers broke ice in the Arctic Ocean, they got stuck on the glacier because the ice was too thick. At this time, the cool rocking icebreaking method was used.”
Bi Fang stretched out his hand and pointed at the swaying Tesis.
Upon seeing this, the water friends had a vague realization in their hearts. Is the Swinging Method now the Swinging Method?
"When the hull of the ship is stuck in the ice, you only need to pump the water tank on one side, and the ship will tilt to one side. On the contrary, pump the water tank on the other side, and the ship will tilt to the other side. This way, water will be pumped back and forth.
, the hull will sway left and right, and at this time, adding more horsepower can help the ship get out of trouble."
I see!
The audience suddenly realized.
【magic】
[This is the first time I know it can be like this]
Bi Fang was not the only one watching the Tesis break the ice from a distance. No one can stand on the deck when the ice is broken by the rocking method. It can easily cause a dangerous situation and make people feel uncomfortable. Therefore, there are still many tourists standing on the ice sheet.
, Captain Harveys was among them.
Seeing Bifang arriving with a sled, many people were attracted to it. Captain Harveys walked over and said solemnly: "The ice is thicker than we thought!"
"guessed."
Bi Fang also had a headache. Normally, the speed of an icebreaker should not be so slow. It could only be that the ice was too thick and Tesis was not professional enough, so it ended up like this.
But at the current speed, there is no problem in rescuing the whales.
The two had a brief conversation and confirmed this consensus.
"Have you eaten?" Captain Harveys invited after ending the conversation.
"No, I'm still trying to survive." Bi Fang explained the reason and was a little curious, "Is it lunch or dinner now?"
Captain Harveys blinked, not surprised, and smiled: "It's breakfast."
"Okay, I happen to be a little hungry too. Would you like some musk musk?"
"certainly."
Just because Bi Fang cannot accept help or food for free does not mean that others cannot accept his help or food.
The two left the crowd, dug a small hole and sat on the ground. Bifang unfolded the musk ox hide from the sled and took out a stick-like object from inside.
It was two wooden sticks put together, one big and one small, like sleeves put together in winter.
Harveys saw Bifang take off the big end, a faint cloud of dust emerging from the stick, and sparks could be vaguely seen in the darkness.
"Is this fire?"
"That's right."
"How did you do it?"
"It's very simple, it's just incompletely burned wood chips."
Bi Fang made tinder, poured out the sparks from the stick, and blew slowly with a big mouth, which quickly lit the flame.
"Controlling fire to provide heat and light is one of the great achievements of early mankind. Early humans retained fire from fire sources produced in nature. Later, they learned to actively obtain fire by drilling wood or knocking flint."
"For survival in the wilderness, fire is our life. We need fire to keep warm, dry our wet clothes, disinfect water, cook food, drive away wild animals, and give us confidence."
Harveys nodded unconsciously.
"But making a fire is not an easy task, and even if you start a fire, you will encounter situations where you need to leave, go out, or move your position. At this time, it is very important to keep the fire."
Bifang explained how to skewer muskox on branches, both to Harveys and to the audience.
"The easiest way is to find a piece of dry, thick wood, preferably a tree root, that is not too dense. Too dense wood will easily burn out. After igniting it, extinguish the open flame, leaving only smoldering sparks."
"In this way, you can carry it a long distance. When it is about to burn out, ignite the next piece and repeat this process, and you can carry it a long distance."
"Be careful not to let the sparks go out during this period. When they are about to go out, blow on them to let them burn. When you need to ignite, just put the tinder on it and blow on it to ignite the tinder.
.”
Captain Harveys nodded, and when he saw the tree stick in Bifang's hand, he knew that this was the method.
"In addition, you can also use bamboo tubes, bark can be rolled into tubes, or clay can be hand-made into tubes or basins. One end of the tube can be fully ventilated, and half of the vents can be left on the other end. Put semi-moist combustible materials first, such as rotten
Leaves, moss, etc., and then put fire. Wait until the inside starts to smoke, then seal half of it with soil. This method of carrying can generally be carried for about 2 hours at a time."
[Two hours is a bit short, right?]
[I also think, doesn’t this need to be remade every day? 】
[Wouldn’t it be enough to just light a bonfire when sleeping at night? The fire should still be kept]
Bi Fang shook his head: "After you make one, open it and blow air every two hours to extend the time. It's not that troublesome. Once all the dry and wet substances inside are burned out, it will last at least a day or two.
.”
The peat soil is constantly burning, emitting amazing heat, roasting the dark red musk meat until golden oil emerges, and a faint fragrance begins to fill the air.
"If you have the conditions, you can also find a fire-starting fungus, which is something that looks like a big mushroom growing on a tree. It's very big and hard. It's actually quite common in the forest."
"After you find it, use fire to ignite some sparks in the middle, and then blow air to let it smolder inside."
"If you want to put it in a backpack, you can put some green moss in the smoldering area to prevent the backpack from igniting and carry it close to your body."
“How long will these things last?”
"Generally, a fire starter like this can smolder for four or five hours. The earliest primitive people carried fire in this way. When it was time to light the fire starter, they would place the fire starter on it and then blow on it to ignite the fire starter."
"It's just that we don't have such conditions in the Arctic."
[Huozhezi has a similar principle, right?]
[It’s the burning relationship between oxygen and fire]
[It is really simple to say, but it is still difficult to do]
"It's an eye-opener!" Captain Harveys' eyes lit up and he was full of admiration.
"You have to have some real skills to make a living from this." Bi Fang smiled, turned the barbecue over, took out a bag of salt from his body, and sprinkled some on the appropriate places.
The oil is continuously secreted under high temperature, and the fragrance becomes more and more intense, which makes people's fingers itch.
Captain Harveys was quite surprised. He accepted Bi Fang's invitation just because he wanted to have a try. After all, he had never eaten musk beef before. He was quite curious, but he didn't really expect much about the taste. Now he was quite surprised.
Looks pretty good?
Finally, sprinkled with a thin layer of salt, Bi Fang handed the prepared barbecue to the captain: "Try it."
After the fat has been heated to high temperatures, a large amount of fat overflows. Such rich fat is not wasted at all under Bifang's superb grilling. It penetrates into the meat fiber again and is finally sprinkled with a thin layer of salt, which makes people appetite.
With such a simple preparation, it is impossible to say that it is so delicious that it will fall off your tongue, but the taste is indeed quite good.
At least Captain Harveys felt that normal people would never be able to make such delicious food using only meat and salt.
A whole piece of thick meat is juicy and you can eat it thoroughly.
"anything else?"
Harveys waved his hand: "No, eating too much meat in the morning is not easy to digest. Please be considerate of the stomach of the elderly."
"The captain is not old."
Bi Fang looked around and saw that Harveys looked about fifty years old.
Harveys smiled and did not answer this question. Instead, he stood up and continued to observe the Tesis breaking through the ice.
