"That's fire!"
"Fire is an indispensable thing for survival in the wild. It can provide light and heat to drive away wild animals and roast cooked food."
"But more importantly, it allows people who are lost in the wilderness to regain their confidence and walk more firmly!"
At this time, some audience members asked: "Yu Shen, without a lighter, how do you make a fire?"
Lu Yu smiled.
In just one sentence, the audience was speechless: "In the primitive era, our ancestors did not have the tools to get fire, but they could get fire anytime and anywhere. Well, everyone, now I'm going to collect some fires The material shows you how to start a fire after leaving civilization!"
The words fall.
Lu Yu stepped into the jungle.
"The humidity in the rain forest is very high. In order to be able to get fire successfully, I will try to collect some drier firewood and firewood."
"The palm tree core is a good choice."
With that said, he approached a palm tree, broke off the leaves at the top, peeled off the green bark, and took out a mass of cotton wool from it.
"This thing is the core of the palm tree, because it is hidden in the deepest part of the palm tree. Even if the surrounding environment is wet, the core of the tree can always be kept dry."
Putting the core of the tree into his trouser pocket, Lu Yu folded some dead branches of the tree along the road, pocketed it with his jacket, and took it back to the camp.
Then he walked around the shelter again.
When he returned, he was already holding a stone with yellow-brown spots.
Holding the stone and shaking it in front of the camera, Lu Yu said: "The fire can't be without the help of a cutting tool, because I don't have a knife, so I have to find a way to solve this problem."
"This is flint, a very sharp stone. As early as the Stone Age, humans have learned to use this stone to make stone knives."
Without explanation, the people in the live room asked again:
"Stone Age?"
"How do stones make swords?"
"I think it should work! Otherwise, how did the ancestors survive?"
...
Looking at the stone in his hand, Lu Yu thought for a while.
Then he quickly got up and came to a rock, and after finding the angle, he smashed it hard against the rock beside him.
"boom--!"
moment.
Flint, torn apart.
Scattered all over the place.
After bending down and choosing something, Lu Yu picked up a fairly sharp piece of stone and put it in his palm. He took it in front of the camera: "Look."
"Is this piece of stone very sharp? Maybe you don't believe it, but it can easily cut through my T-shirt--"
With that said, Lu Yu immediately demonstrated it to the audience.
Raise the stone knife and cut it gently in his T-shirt.
Soon, the audience heard a "thorn".
Looking at Lu Yu's T-shirt, a long mouth has appeared.
Seeing this scene, everyone's eyes shined!
Unexpectedly, a knife can be made with only stone?
"Lying trough, it looks pretty sharp!"
"Feather, you are such a clever ghost!"
"I said long ago that stones can be used for knives, and you don't believe it!"
"A fire in winter is presented to the anchor plane × 5!-Do it yourself!"
"Bustless squeeze gift to the anchor super rocket × 1!-Too Niu B!"
...
In front of the shelter.
Lu Yu sat on the floor.
According to the first, second, and third levels of the firelighters, they are divided into categories.
Everything is ready, he slowly opened his mouth:
"Firewood is there, so is the cutting tool. Next, I will show you a very primitive method of getting fire-drilling wood to get fire!"
The audience in the live broadcast room is no stranger to this term.
Many people know how to drill wood for fire, as well as the historical evolution of primitive society.
However, in this extremely technologically advanced world, the method of making fire by drilling wood is still forgotten by many people.
Almost no one has ever seen the so-called "drilling for fire".
The impression about drilling for fire is only derived from books or science and education documentaries.
If it were not for Lu Yu to remind, most people did not expect him to use this primitive way to raise a fire.
"Lying trough!"
"Drill wood for fire?"
"How is this possible, don't blow the anchor!"
"I have only seen logs and fire in books, and I have never seen anyone play like this before!"
"Wait!"
"real or fake?"
Ignoring the barrage in the live broadcast room, Lu Yu continued:
"There are three methods of drilling wood for fire, which are hand drilling, rope drilling, and bow drilling."
"Because the conditions and time are limited, today I will show you a hand drill that is relatively simple to operate."
"The hand drill method is very different from the other two methods of making fire. It is simple, easy to operate, and does not require any special tools. The only drawback is that the success rate is not as good as the first two."
"First of all, we need to find a relatively flat wooden board to serve as a drill board, and then find a small wooden stick as a drill rod."
Rummaging through the firewood.
It took a lot of effort before Lu Yu found a suitable wood board and stick for drilling boards and rods.
"Wait a minute, I need to dig a hole in the edge of the drill plate to make an ember groove for the ember to dump, and then use one end of the drill rod to resist the ember groove and turn it continuously, as long as enough ember has accumulated, It can be put in a firelight to blow air to support combustion."
With that said, Lu Yu began to demonstrate to the audience.
Picking up the stone knife, he first dug a hole in the edge of the drill plate.
Due to the limitations of the tool, the shape is not very regular, but the problem is not big.
Immediately afterwards, he found another dry leaf and placed it under the hole.
"This leaf has a term called the ember disk."
"During the friction between the drill rod and the drill plate, a large amount of embers will be generated. This is the fuze that ignites the fire source, and the task of the ember disk is to gather the fuses together and maintain the temperature."
Arrange the drill plate.
Lu Yu repaired the drill rod with a stone knife to make it more regular, and then took the palm tree core out of his trouser pocket and set it aside.
quickly.
Ready to work.
He moved his shoulder a little, aligning the tip of the drill rod with the hole in the drill plate.
Then, gently clamp the drill rod with both hands and repeatedly rub back and forth!
"Oh, uh--!"
Time elapsed in one minute and one second, and the live broadcast room was filled with the friction sound of wood.
Everyone's eyes fell on Lu Yu's hands.
"Slot, what hand speed is this?"
"At least 20 years of being single!"
"Like Feather God's Unicorn Arm!"
"233333"
"The muscles are really strong!"
Over time, Lu Yu could clearly feel that his palm began to heat up!
Holes in wooden boards also have a sudden rise in temperature due to friction.
Gradually.
The wood began to change color.
Through the lens, I have even seen plumes of black smoke...
