In the narrow boulder cave, flames licked every corner, and the unique smell of smoke from burning plants spread around.

Inside are all dead branches that Bifang specially collected from trees, and the smoke is not too big.

"The drier the materials for making a fire, the better. The easiest way is to pick up dead branches. Generally, the dead branches that fall on the ground are relatively moist, especially in humid places. However, the dead branches that are still in the air should be drier. Use a wooden stick to

If you hit the lower branches, the ones that will fall off will naturally be dead branches.”

In order to prevent the flames inside from breaking out and causing a fire, Bi Fang dug a ditch around it. There was no water in it, but the plants that could easily cause burning were dug out, leaving only the moist soil at the bottom.

Taking advantage of the time to use flames to sterilize and kill insects, Bi Fang and Bao Weiss began the long tree-lugging session.

"Stones and wood are the easiest materials to obtain for survival in the wild, and they are also two materials that can bring great help. The former is hard and can be made into weapons, while the latter is adaptable and can also be made into various tools."

Two men carried two stone axes and raised the thick tree stump, preparing to split it.

"When using a stone ax, be careful not to swing it at any part of your body." Bi Fang guided Bauwis on the correct posture for using the axe.

"First spread your legs, and then place the thing you want to chop directly in front of you."

Placing the thick tree stump in front of him, Bifang raised the stone ax and chopped it straight down from top to bottom.

"The direction of the force must be in a straight line. Assuming there is no object in front of you, the swinging ax will make a circle around your shoulder and reach the space between your legs."

"Many people are prone to deflection due to muscle groups, lack of strength, and lack of mastery of skills. But the less strength they have, the more they have to do as I say."

Bauwis asked: "Isn't it because you don't have enough strength to lose control and hurt yourself more easily?"

Bi Fang nodded.

The correct direction of exerting force should be from the legs, where the strength is accumulated, and then to the waist as the core explosion zone, rather than simply using arm strength.

"But most people don't know how to exert force, and due to the difference between their left and right hands, they often turn the front chop into an oblique chop. If the position is incorrect, once they break away, it will be easy to chop on their calves or even thighs. The former

There may be fractures, which may split a major artery."

Bowers' hand trembled.

But they saw that Bi Fang had already raised the ax in his hand, standing straight with his legs spread apart, and then slashing downwards. His whole body was like a loosened big bow. After the strength was accumulated to a certain level, he loosened the bowstring.

Bi Fang did not use all his strength. As he said, it is easy to lose control of his full strength and injure himself in an accident.

The sharp stone ax cut through the air and struck directly into the texture of the tree stump. The stone rubbed against the wood and squeezed in forcefully.

boast.

Accompanied by a clear sound of wood splitting, the audience's eyes widened as they watched the entire tree stump split into two halves!

【High-end game player!】

[Fuck, awesome, 666, three consecutive unrivaled results!]

【I want to learn this!】

Bi Fang smiled and said: "This is a pine tree, the most common tree in the wilds of Yang country. Its wood is not good, it is very soft. It is known as one of the worst solid woods. Split it along its grain.

If you have enough strength and master the skills, it is not difficult to separate at one time, and many veteran workers in the lumber mill can do it."

Furthermore, the tree stump itself is not thick. With my current explosive power, it is strange that I cannot split it in one go.

But even so, it was enough to surprise Bowers.

A veteran of the lumber mill?

They all use sharp iron axes!

Let Bauwis try to split the wood by himself, while Bi Fang laid the split wood horizontally on the ground and used daggers and stones to cut grooves.

"In fact, many times, the hand saw is a very useful tool in wilderness survival, and can even completely replace an axe."

"The ax is used to cut down trees. It is not as efficient as a hand saw and requires more effort. The ax can be used as a hammer, but not a saw. But the function of the hammer can be easily replaced. Just find a thick stick or stone. After all, the scene where the hammer is used is

Not much. For the function of chopping firewood, the knife can replace the axe.”

"The disadvantages of axes are: first, they are heavy. Most of them weigh 1,500 grams, while hand saws only weigh 300 to 400 grams. Second, they are dangerous and more likely to hurt themselves. Many experienced hands are prone to missteps."

[Then why does Lao Fang still use an ax?]

"Because I can't make a saw in the wilderness." Bi Fang smiled, but paused and denied, "Actually, it's not impossible. I can make steel just like I made the dagger before, and then make a rough saw.

saw blade, but the cost would be too high.”

It is impossible to spend more than ten or twenty days just for a saw blade.

With this time, all the work that the ax can do has already been done.

"Wet wood saws for gardening, Japan's Red Fox, and Okada are relatively famous. Domestic ones are also available. The more expensive ones are sharper. The difference is not too big. You can save 10 to 20% of your time. There is not much difference in the hardness of the saw teeth.

, finish the game as if you’ve hit a rock.”

"Some saw blades are softer and more elastic. If you push hard, they will bend if they get stuck, but they will not break. The saw teeth are divided into thick and thin models. If you only bring one, you will naturally buy the medium size. The length of the saw blade is more than 20 centimeters.

suitable."

"The back of the hand saw can be polished in advance to sharpen the blade, so that it can be used for two purposes."

"Don't think about sawing a tree that is too thick. An arm's length is enough. You need to saw the tree into sections first and then chop them thinly. Just use a knife and a wooden stick to chop each section of log."

Although he had never used it before and probably never had the opportunity to use it, Bi Fang still shared with the audience the usage and function of a saw.

After all, my own survival is closer to extreme survival, but in fact, bringing a few tools can make survival much easier.

Knock the handle of the dagger with a stone, hollow out the semicircular wooden stake bit by bit, and make a large wooden trough. Then use a knife to dig out small holes little by little on both sides of the wooden trough and weave it with bark.

The thick rope that comes out is passed through, which makes it easier to drag.

Bowes followed Bifang's example and made a wooden trough, but the speed was much slower. When Bifang finished, he only took out less than half of it.

Bi Fang took this time to go to a small river not far from the cave, fetched some water, poured it into the wooden trough, picked out a few rocks that were blackened by the fire, clamped them with branches and threw them away.

Go in.

Not to mention other countries, there are also many rivers. You can encounter lakes or rivers within a few kilometers.

With a sneer, a large amount of white water vapor evaporated.

After the stone cooled, Bi Fang picked it out with a branch and placed it in the stone three times. The water in the wooden tank was close to boiling.

At this time, the flames in the cave were almost extinguished, and the plant ash inside was not cleaned and collected. Bifang directly spread it over.

Then fill the gaps at the bottom of the cave with small stones.

The gap is quite large, about half a hand wide, which is very suitable for some small bugs to live. If it is not blocked, mosquitoes will gather here again in less than two days.

Wait until the stones are almost filled, then pile plant ash in to completely block the small gaps.

The floor of the cave appears to be very flat.

Bi Fang then started to pile up stones on the other side. They were all big stones that had been moved out before. One by one, they were careful to size and shape, and they were piled up smoothly, just like playing Tetris.

"You must be a good player at Tetris." Bowes knelt down and looked at the perfectly fitting stones, exclaiming in admiration.

They are obviously just ordinary stones without any cutting, but Bi Fang seems to be able to remember all their shapes at a glance, and then naturally knows how to match them, leaving no big gaps and keeping them all within one finger.

The stones only filled half of the cave. It is not difficult to see that Bifang wanted to make a "stone bed".

"The next step is to use clay."

Bi Fang walked out of the cave, poured the previously dug clay into another wooden trough without boiling water, then poured a small amount of boiling water into the other wooden trough and began to mix thoroughly.

Then a handful of clay and a stone were used to raise the stone bed like cutting bricks, leaving no gaps.

But Boweis soon noticed that Bifang left a long groove of about twenty centimeters in the middle of the stone bed.

Bi Fang saw Bao Weisi's expression and explained: "This is a thermal insulation tank. You can burn a fire in it, so that the residual heat will spread over the stone bed, and it will also play a fixed role later. In China, this is a

A very common architectural form, especially in high latitudes."

It is said to be a thermal insulation tank, but it is actually an earthen kang in the Northeast. However, Bifang explained it in a more understandable way, saying that it is an electric blanket in the wilderness.

[I understand, slate barbecue]

[About Bi Fang’s trip to the north]

[Handmade by master, exquisite]

Bowes wiped the sweat from his forehead. Although he was sweating, it was caused by exercise. The air was still cool, far from cold, so there was no need to keep warm, right?

"Of course it's not necessary, but I'm more interested in showing off my skills."

Bowes was stunned.

"Our lives seem very calm and peaceful, and many accidents seem far away from us, but in fact everyone is at certain safety risks. In real life, accidents can happen at any time, including various natural and man-made disasters.

It threatens our safety all the time."

"Earthquakes, floods, fires, car accidents and other sudden disasters happen from time to time, and there are always small tribulations in life, such as malfunctioning elevators, burning buildings, aircraft breakdowns, car distress, accidental injuries, sudden illness, food poisoning, etc.

wait......"

"In the face of emergencies, we cannot survive by chance, but need to master the necessary knowledge. Knowing self-rescue and first aid knowledge, learning some self-defense skills, and understanding wilderness survival knowledge can enable us to survive in various situations.

Everyone can live peacefully wherever the circumstances arise.”

"Various sudden dangers are unpredictable and irreversible in nature, and all situations require timely treatment. In the face of disasters, many people panic because of their lack of self-rescue and first aid knowledge, and miss the best rescue time, leading to tragedies.
