After taking a while, Bi Fang rushed to his own cabin and looked at his cabin across the river.

Intact.

The sloping roof didn't pile up much snow, only three inches thick, and above the door of the hut hung a pale, hideous cow skull.

Although it is a little scary, it adds a wild and angry atmosphere.

[To be honest, this picture is a bit beautiful.] 】

[Indeed, the ice fields, rivers, wooden houses, and the faint purple starry sky are beautiful]

[It's so beautiful, I really want to travel to the North Pole]

[Already booked tickets]

【Where can I buy a ticket for the Tesis, I want this】

Some sailors sighed and sent out a barrage, looking as if they wanted to live in it directly and stick to nature at close range.

In such an atmosphere, Bi Fang said quite sadly: "There is no modern equipment in it, the food is not good, the seasoning is only salt, and you have to be careful to freeze your little brother when you go to the toilet, I really can't stand most of the people who live in, oh, one thing is still good, that is, using snowballs as toilet paper, it does feel much better than paper." ”

[Hmm, don't spoil my beautiful fantasy! 】

[Indeed, without Fang Shen's ability, most people can't experience comfort at all, and can only feel the feeling of struggling in a desperate environment]

[Woo woo, leave some beauty for me]

Ignoring the wails of the sailors, he crossed the river and returned to the shelter, and instead of rushing to find fuel, Bi Fang went to the place where he had buried the musk beef.

After a closer inspection, he breathed a sigh of relief after confirming that there were no traces of damage, and smiled at the audience: "Luckily, there have been no small animals breaking in in the two days we have been out, or we have not found the 'treasure' buried here." ”

If you want to say what Bi Fang is most worried about when he goes out, there is no doubt that it is the musk ox buried in the ground, for fear that some animal will come to dig a pit and snatch away his hard-earned booty.

When the time comes, I will fall into a passive state again, although there is still fish and meat to supplement, but there is always a lack of security in my heart.

After simply taking some meat, Bi Fang changed places and continued to dig the pit, and then put the excess musk meat back into it and buried it again.

"When we dig it up, the excess snow mixes together, and there will inevitably be some smell on it, which is easy for animals to spot, so we have to rebury it so that it is safe enough."

After getting the food and giving the three fools a full meal, Bi Fang began to collect fuel.

"First of all, it's fuel, put more peat soil, they have a high calorific value."

Bi Fang put the mud bricks frozen into blocks one by one into the basket, and the bricks that were frozen like rocks were hard and neatly stacked.

The basket is made of woven wooden strips in a cylindrical shape, and there are many gaps around it after adding mud bricks, which are filled with hardwood.

"Hardwood burns longer, 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 the average peat soil, but from building the kiln to burning, it takes at least three hours, and we will not waste that effort."

This pile of fuel, almost twelve or thirteen kilograms, is enough for three days to save a little use.

"A kilogram of charcoal can theoretically burn for eight hours, of course, the environment in the Arctic will accelerate this process, so we need shelter, even if we don't have charcoal on hand, but peat soil and hardwood, but three days, three hours a day, it's more than enough to keep warm, or cook something."

Bi Fang made a simple calculation with the audience, and then placed the basket on the sleigh, then the food, and some tools, the total weight of which added up to the weight of an adult.

After all, there are only three sled dogs, and the weight of two people is already the limit of being able to run continuously, and any more may affect efficiency.

Getting his things ready, clearing the snow from the wooden roof, Bi Fang drove the sleigh out of the shelter and back in front of the Tesis.

Under the night sky, the Tesis was fighting against the ice, and the most amazing thing was that the expedition ship was slowly falling to one side, and the spectators screamed wildly.

[the groove, the groove, what's going on???? 】

[Are you going to fall?] Is it going to fall? 】

[Why did the ship sink suddenly??? 】

[It's over!! 】

"Don't be surprised, it's normal."

Bi Fang's tone was flat, not frightened by the tilt of the Tesis.

You call this normal operation!?

The sailors stared at the Tesis with a huge inclination angle, and their faces were incredulous.

"Of course, to put it simply, the icebreaker uses the downforce of the bow to break the ice, and there are generally three ways to break the ice, which are continuous, ramming and swinging."

"When encountering ice no more than 1.5 meters thick, the icebreaker will use the continuous icebreaker method, using the power of the propeller to climb the hull on the ice first, and then slap down to smash the ice, but the driving force of the propeller is not vegetarian, it runs like a knife, and it can chop the ice in minutes."

"When the thickness of the ice layer exceeds 1.5 meters, it is necessary to use the collision icebreaking method, first use the bow of the ship to crush the thick ice layer into pieces, and then backwards for a distance and then sprint forward, at this time the momentum is enough to hit the broken ice blocks, and use the power of the hull itself to repeatedly hit it many times to open up a new channel."

"When the Tesis first appeared, it was a direct collision, because it was close to the coast, the ice was very thin, and it could even be said that some of it was ice floe, so it could advance more than 100 meters at once, and then it was not so easy."

"Although such a violent icebreaking method is not only inefficient, but also a huge damage to the hull itself, which needs regular maintenance, so the new ship icebreaking structure is still being studied, but no matter how foolproof the icebreaking method is, it will also encounter special situations, such as being stuck in the ice and so on."

"In the past, when European icebreakers broke the ice in the Arctic Ocean, the ice was too thick to move on the stuck glacier, and now the cool swinging icebreaker method is used."

Bi Fang stretched out his hand and pointed to the swaying Tesis.

Seeing this, the sailors faintly realized in their hearts, the swing method, is it the swing method now?

"When the hull is stuck in the ice, just pump one side of the tank, and the boat will tilt to one side, and conversely, if the other side tank is pumped, the boat will tilt to the other side, so that the water is pumped back and forth, and the hull will sway from side to side, and then the full horsepower can get the boat out of trouble."

I see!

The audience suddenly realized.

【Magical】

[The first time I knew that I could do this]

Standing in the distance to see the Tesis break the ice, there are not only people on the deck who can stand on the rocking method to break the ice, it is easy to cause dangerous conditions, and it is not comfortable, so there are many tourists standing on the ice field, and Captain Harvey is also among them.

Seeing Bi Fang coming with a sleigh, many people were attracted to it, and Captain Harvey came over and said solemnly: "The ice is thicker than we thought!" ”

"Guessed."

Bi Fang also had a headache, the normal icebreaker should not be so slow, it could only be that the ice was too thick, and Tesis was not professional enough, so it became what it is now.

It's just that at the current rate, there is no problem in rescuing the whales.

After a brief conversation, the two confirmed this consensus.

"Have you eaten?" Captain Harveys, who ended the conversation, extended an invitation.

"No, I'm still trying to survive." Bi Fang explained the reason, a little curious, "Is it lunch or dinner?" ”

Captain Harvey blinked, not surprised, and smiled, "It's breakfast." ”

"Okay, I happen to be a little hungry too, do you want some musk beef?"

"Of course."

Just because Bi Fang can't accept help or food doesn't mean that others can't accept his help and food.

The two of them left the crowd, dug a small pit and sat down on the ground, Bi Fang spread out the musk cowhide from the sleigh and took out a stick in it.

It was a combination of two wooden sticks, one large and one small, like sleeves put together in winter.

Harvey saw Bi Fang take off the big one, a faint dust came out of the stick, and in the darkness, the spark could be faintly seen.

"Is this tinder?"

"That's right."

"How?"

"It's very simple, it's wood chips that haven't burned completely."

Bi Fang made velvet, poured out the sparks in the stick, blew slowly, and soon lit the flames.

"Controlling fire to provide heat and light was one of the great early achievements of mankind. Early humans kept fire from the sources of fire produced in nature. Later, he learned to use the method of drilling wood for fire or striking flint to obtain fire. ”

"For wilderness survival, fire is our life. We need fire to keep warm, dry our damp clothes, disinfect water, cook food, drive away wild animals, and give us confidence. ”

Harvey nodded unconsciously.

"But it's not easy to start a fire, and even if it does, you will need to leave, go out, or move your position, so it's important to keep the fire."

Stringing musk beef on a tree branch, Bi Fang explained it to Harvey and to the audience.

"The easiest way is to find a piece of wood that is relatively thick, preferably at the roots, and not too dense. If the density is too large, it is easy to extinguish. Ignite it and extinguish the flames, leaving only sparkling to burn. ”

"So you can carry a long distance, and when it's about to burn out, ignite the next piece and repeat it, you can carry a long distance."

"During this period, be careful not to let the spark go out, and when it is about to go out, blow on it and let it burn. When you need to ignite, just put the igniter on it and blow into it to ignite it. ”

Captain Harvey nodded, and when he saw the stick in Bi Fang's hand, he knew that this was the method.

"In addition, you can also use bamboo tubes, roll tree bark into tubes, or make clay into tubes or pots by hand. The cylinder is fully ventilated at one end and half of the vent is left at the other end. Put semi-wet combustibles first, such as rotten leaves, moss, etc., and then set fires. Wait until smoke starts to come out inside. Seal half more with clay. This type of carrying can generally be carried for about 2 hours at a time. ”

[Two hours is a bit short, right?] 】

[I also think that this is not a daily remaster? 】

[Isn't it over when you sleep on the bonfire at night, the fire is still kept]

Bi Fang shook his head: "After making one, open it every two hours to blow and blow it to continue the time, it's not so troublesome, and when all the dry and wet substances in it are burned out, at least it can be used for a day or two." ”

The peat soil burned incessantly, emitting an astonishing amount of heat, roasting the dark red musk beef to the point of golden oil, and a faint aroma began to fill the air.

"If you have the conditions, you can also find a piece of fire starter, that is, something that grows on a tree like a big mushroom, which is particularly large and hard, and it is actually more common in the forest."

"Once found, use fire to ignite some sparks in the middle of it, and blow it to smoldering inside."

"If you want to put it in your backpack, you can put some green moss in the smoldering area to prevent it from igniting the backpack and carry it with you."

"How long do these things last?"

"Generally, one of these ignition bacteria can be smoldered for four or five hours. The earliest primitive people have carried fire in this way, and when it is necessary to ignite the ignition, put the ignition on it, and then blow the air to let it ignite the ignition. ”

"It's just that we don't have such conditions in the Arctic."

[The fire fold is also a similar principle]

[It is the burning relationship between oxygen and fire]

[It's really easy to say, but it's still more difficult to do]

"Eye-opening!" Captain Harvey's eyes lit up and he was amazed.

"You have to have some real skills to eat from this." Bi Fang smiled, turned the barbecue over the surface, took out a bag of salt on his body, and sprinkled some in the appropriate place.

The oil is constantly secreted at high temperatures, and the fragrance becomes more and more intense, which is appetizing.

Captain Harvey was quite surprised, and accepted Bi Fang's invitation, just to try it, after all, he had never eaten musk beef, so he was quite curious, but he didn't have much expectation for the taste, and now it was quite unexpected.

Looks like it's pretty good?

Finally, sprinkled with a thin layer of salt, Bi Fang handed the prepared barbecue to the captain: "Taste it." ”

After the high temperature, a large amount of fat overflows, such a rich fat, but under Bi Fang's exquisite roasting, there is no waste, once again penetrates into the meat fiber, and finally sprinkles with a thin layer of salt, which makes people appetite.

With such a simple treatment, it is impossible to say that it is so delicious that it falls off your tongue, but the taste is indeed quite good.

At least Captain Harvey thinks normal people can't make such delicious food with just meat and salt.

A whole piece of thick gravy is rich in water and eats it cleanly.

"Do you want more?"

Harvey waved his hand: "No, it's not easy to digest if you eat too much meat in the morning, be considerate of the stomach of the elderly." ”

"The captain is not old."

Bi Fang looked at him, and Harvey looked like he was about fifty years old.

Harvey smiled and didn't answer the question further, instead getting up and continuing to observe the Tesis as it broke through the ice.
