Chapter 457 The Fire is Coming
Finally, finally!
When the audience heard that Bifang was finally going to talk about the third way to make fire, their eyes were filled with tears.
It’s been a year, it’s been a year!
Does Fang Shen know how they spent this year?
[Lao Fang said he had several ways to make fire? ]
[I forgot, six, seven, eight, nine, right? ]
[A year has passed, and I have only taught the third type. I am afraid that I will have to teach all of them in my lifetime.]
[After Fang Shen has taught me all the methods, don’t forget to tell your father during the family sacrifice, and then burn paper for me using those methods! ]
[Drilling wood to make fire, spare me, dog head.jpg]
[It was as if I saw a filial young man sweating profusely while drilling wood to make fire on a grave.]
Make fire?
In addition to the audience, Leonardo on the side had the same expression. After being here for so long, he was finally going to participate in something with some symbolic significance!
"Is it that exaggerated?" Bifang laughed. "It's been a while since I taught you how to make fire in the wild. In fact, the method of making fire with bare hands is adaptable in different places."
"In addition to drilling wood and pumping fire, I also taught people how to make fire using an ice lens in Mohe. That is to adapt to local conditions. And in the tropical rain forest, making fire with a fire saw is one of the most suitable methods."
【one?】
[I realized that things were not as simple as I thought]
"Most wood in the rainforest is very wet, only a small part is relatively dry, such as bamboo, so one of the best materials for making fire in the jungle is bamboo. We need to choose dry bamboo that is about 60 cm long and 4 to 5 cm in diameter."
Is it difficult to find bamboo in the Yunnan tropical rain forest?
It's as difficult as reaching into your pocket.
Simply put, take something out of your bag...
"The origin of bamboo is China, and Yunnan Province is a province with abundant bamboo germplasm resources. The natural bamboo forest area alone is nearly 4 million mu. It can be said that there is no place in the world, or even in China, where bamboo is easier to find than Yunnan."
Even when Leonardo and Bifang came here just now, they saw it several times.
Therefore, it didn't take long for Bifang to find the right material and use a relatively sharp stone to smash out a piece of suitable material.
Bifang stood the bamboo tube upright, propped one end against it with a stone, and then smashed it down with a stone , and the bamboo tube instantly split into two halves.
"We have to split the bamboo in half first. Lay one of the pieces flat on the ground as a saw board, with the cut side at the bottom and the curved side at the top. If you are alone, make sure to hold it in place. If there are others, you can ask them to help hold it down."
Leonardo pressed the wooden board very consciously.
“Then we cut grooves in the curved surface to hold the saw in place.”
The bamboo board was held down firmly, and Bifang 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 hold the main saw blade.
"We also use bamboo for our saw blades. We remove all the bamboo nodes. We clean one side of the bamboo and process it smooth and flat. We place the smooth and flat side vertically downward on the saw board."
The other saw blade was continuously polished by Bifang with a stone, and the fallen bamboo fibers and debris were not thrown away but collected.
This is also an excellent ignition material.
Bifang put the saw blade into the groove on the saw board, kept the saw blade tilted to a certain degree, pressed both ends of the saw blade with both hands, applied a certain amount of pressure, and then began to rub it back and forth, while explaining to the audience.
"Like any other friction fire-making method, start by slowly pushing and pulling the saw blade on the saw board until smoke comes out of the board. Then you can increase the speed and pressure until a lot of smoke comes out of the saw board or the saw blade can no longer be pushed or pulled."
"This will form charcoal fire in the gaps under the saw board. This charcoal fire is also relatively weak, so it should be ignited with some dry, fluffy and flammable materials, and be careful not to extinguish it."
“Like now!”
As he spoke, a light smoke was already coming out of the trough.
Leonardo, who was holding down the saw board, widened his eyes in disbelief. It had only been a short time and yet it started to smoke?
Seeing that smoke was already coming out, Bifang increased his speed and continued to apply pressure. The smoke became thicker and thicker, even making Leonardo, who was standing next to him, want to cough.
Just as he was about to cough, Bifang quickly stopped and took out the saw blade. The smoke did not stop but continued to roll: "If there is still thick smoke after taking out the saw blade, it means that there is charcoal fire in the trough. It seems that we are lucky and succeeded in one try."
Bifang happily gathered the bamboo shavings and bamboo fibers that had just been scraped off and placed them on the saw board. He carefully held them up with both hands and blew them slowly with big breaths.
Under Leonardo's incredible witness, the originally thick smoke became even more turbulent, and in a moment, a burst of fire flashed between Bifang's fingers!
"It's on fire! It's on fire!" Leonardo, who witnessed the miracle, seemed even more excited than Bifang himself. "It's incredible, so incredible."
[Fuck! This is too fast, isn't it? ]
[The old method seems to be more powerful each time. Drilling wood is complicated and difficult. The pump method is simple but the assembly is complicated. This fire saw is simple and fast! ]
【Learning is useless. Learning is useless.】
【Let’s set fire to the mountain tonight! 】
Leonardo shouted excitedly: "If you don't participate in it in person, you will never be able to feel the sense of achievement. It's amazing, really amazing."
Far away from industrial civilization and human society, a ball of fire was created out of thin air from nothing!
"If it were in the Middle Ages, you could even use this to become a charlatan!" Leonardo said with emotion.
Bifang curled the corner of his mouth. Is this a compliment?
Fortunately, he didn't care too much. He placed a stone slab on the stacked stone platform, and then poured all the red mud in the leaf funnel onto it.
"The next step is heating it. This process is very simple. Just keep stirring it until it becomes dry sand-like. The whole process is the same as sun-drying to kill insects and bacteria."
At this time, the drone camera gave a close-up, showing countless insects and ants fleeing everywhere in the rolling red mud.
Many even die directly under high temperatures. There is nothing we can do about it. Without drying them in the sun, they can only be baked, and there is no way to avoid the dead bodies of insects inside.
"Once it becomes dry sand, we can pour clean water into it and apply it on our bodies. Of course, if there is grease, we can add the grease directly, which will be even better. In this way, when the water evaporates , the red mud will still not dry out."
While waiting, Bifang was not idle. He walked around and found a good vine.
"In addition to using saw blades, we can also use a 90-120 cm long dry and flexible rattan to make fire. At this time, the saw board is placed in the opposite way to before, with the curved surface at the bottom and the cut facing up, and the rattan is used to saw repeatedly on it. This method is called the 'rattan sawing fire method', and it is also a very effective way to make fire after practice. How about it, do you want to try it?"
"I?"
Leonardo looked at Bifang with some surprise.
But then, his eyes became eager to try .
