Chapter four hundred and fifty seventh fire is coming
Finally, finally!
The audience burst into tears when they heard that Bi Fang was finally going to talk about the third way to make fire.
One year, one year!
Does Fang Shen know how they spent this year?
[Lao Fang said he had several ways to make fire?]
[Forgot, six, seven, eighty-nine, right? 】
[A year has passed before I taught the third type. I’m afraid it won’t be a series in my lifetime until I teach them all]
[When Fang Shen has finished teaching all the methods and has not forgotten to tell Naiweng about the family sacrifices, use those methods to burn paper for me!]
[Drill wood to make fire, go around me, dog head.jpg]
[I seem to see a filial young man sweating profusely on a certain grave, drilling wood to make fire.]
Make fire?
In addition to the audience, Leonardo on the side had the same expression. After coming here for so long, he was finally going to participate in something with some symbolic meaning!
"Is it that exaggerated?" Bi Fang was amused. "After all, I haven't taught you how to make fire in the wild for a long time. In fact, the method of making fire with bare hands is also adaptable in different places."
"In addition to drilling wood to make fire and pump-type fire making, I also taught the ice lens fire making method in Mohe, which is based on local conditions. In the tropical rainforest, fire sawing is one of the most suitable methods."
【one?】
【I realized that things are not as simple as I thought】
"Most of the wood in the tropical rainforest is very moist, and at least a small part is relatively dry, such as bamboo, so one of the best materials for making jungle fires is bamboo. We need to choose dry bamboo that is about 60 centimeters long and 4 to 5 centimeters in diameter."
Is it difficult to find bamboo in the Yunnan tropical rainforest?
The difficulty is no less than reaching into your pocket to take something out.
To put it simply, explore the bag and get something...
"The origin of bamboo is China, and Yunnan Province is the province with the largest bamboo germplasm resources. The natural bamboo forest area alone is nearly 4 million acres. It can be said that there is nothing better than Yunnan in the world, or even in China.
It’s easier to find places for bamboo.”
Even Leonardo and Bi Fang had seen it several times on their way here.
Therefore, it didn't take long for Bifang to find suitable materials and use a relatively sharp stone to smash out the expected material.
Bi Fang erected the bamboo tube, put a stone against one end, and then smashed it down with a stone. The bamboo tube split into two halves instantly.
"We need to split the bamboo in half first. Lay one piece flat on the ground as a saw board, with the cut on the bottom and the curved side on top. If you only have one person, be sure to secure it. If there are others, you can call someone else
Help hold it down."
Leonardo held down the wooden board very consciously.
“Then we cut grooves in the curved surface to hold the saw in place.”
The bamboo board was firmly pressed, and Bi Fang held a sharp stone in his hand and cut a groove horizontally on the curved surface of the bamboo used as a saw board. This groove was used to clamp the main saw blade.
"We also use bamboo for our saw blades, and remove all the bamboo knots on the top. In order to clean and smooth one side of the bamboo blade, place the processed smooth and flat side vertically on the saw board.
"
Another saw blade was continuously polished by Bi Fang with stones, and the fallen bamboo fibers and debris were not thrown away, but collected.
This is also an excellent igniter.
Bi Fang put the saw blade into the slot on the saw board, kept the saw blade tilted to a certain extent, held both ends of the saw blade with both hands, applied a certain amount of pressure, and then began to rub it back and forth, not forgetting to explain to the audience while rubbing it
road.
"Similar to other methods of making friction fire, first push and pull the saw blade slowly on the saw board until the saw board smokes. Then you can increase the speed of pushing and pulling the saw blade and increase the pressure until a large amount of smoke comes out of the saw board.
When there is smoke or when the saw blade cannot be pushed or pulled."
"In this way, a charcoal fire will form in the gap under the saw board. This charcoal fire is also relatively weak, so some dry, fluffy and flammable materials should be used to ignite it, and be careful not to extinguish it."
"Like now!"
As he spoke, a faint smoke emerged from the tank.
Leonardo's eyes widened as he held down the saw board. He couldn't believe it. How long had it been before it started to smoke?
Seeing that the smoke was coming out, Bifang increased his speed, and at the same time, he kept spraying the smoke at home. The smoke became bigger and bigger, and even made Leonardo nearby want to cough.
Just when he was about to cough, Bi Fang quickly stopped and took out the saw blade. At this time, the smoke did not stop, but continued to roll: "If there is still thick smoke after taking out the saw blade, it means there is already a charcoal fire in the tank.
, it seems we were lucky and succeeded in the first attempt.”
Bi Fang happily gathered the bamboo chips and fibers he had just scraped off and placed them on the saw board. He carefully picked them up with both hands and blew them slowly.
Under Leonardo's incredible witness, the original thick smoke became more turbulent, and within a moment, a flame flashed between Bifang's fingers!
"There's a fire! There's a fire!" Leonardo, who witnessed the miracle happening on the sidelines, seemed more excited than Bifang himself, "It's incredible, it's incredible."
[Holy shit! Isn’t this too fast? 】
[Lao Fang’s method feels more powerful every time. Drilling wood is complicated and difficult. Although the pump type is simple, its assembly is very complicated. This fire saw is simple and fast! 】
[If you learn nothing, you will learn nothing]
【I’m going to set fire to the mountain tonight!】
Leonardo shouted excitedly: "Without personal participation, you will never be able to feel the sense of harvest and accomplishment. It's amazing, it's really amazing."
Far away from industrial civilization and human society, a flame was created out of thin air from nothing!
"If it were in the Middle Ages, you could even be a magician by relying on this!" Leonardo sighed with emotion.
Bi Fang twitched his lips, is this a compliment?
Fortunately, he didn't pay too much attention. He placed a stone slab on the stone platform where the construction was completed, and then poured the red mud in the leaf funnel onto it.
"The next step is to heat it. This process is very simple. Just keep stirring until it becomes dry sand. The whole process is the same as drying it in the sun to kill insects and sterilize it."
At this time, the drone lens showed a close-up of countless insects and ants scurrying around in the rolling red mud.
Many even died directly under high temperatures. There was nothing we could do about it. We had no choice but to bake them. There was no way to avoid the corpses of insects inside.
"When the sand becomes dry, we can pour clean water again and smear it on the body. Of course, if there is oil, you can add the oil directly. That would be better. Then after the water evaporates, the red mud will still not be there.
It will dry out and crack.”
While waiting, Bifang was not idle. He walked around and found a good cane.
"Actually, in addition to using a saw blade, we can also use a 90-120 cm long dry and soft rattan to make fire. At this time, the saw board is placed exactly opposite to the previous one, with the curved surface down and the incision facing up.
The strips were sawed over and over again.
This method is called the ‘rattan sawing method of making fire’, and it is also a very effective method of making fire after practice. What do you think, do you want to try it?”
