"That's fire!"

"Fire is an indispensable thing to survive in the wild. It can provide light and heat, drive away wild beasts, and bake food. ”

"But more importantly, it allows people who have been lost in the wilderness to regain their confidence and move on more resolutely!"

At this time, some viewers asked: "Yushen, how can you make a fire without a lighter?"

Lu Yu smiled.

Just one sentence left the audience speechless: "In primitive times, our ancestors did not have the tools to make fire, but they could get fire anytime and anywhere." Alright, guys, now I'm going to collect some materials to make fire, and show you how to make fire when you leave civilization!"

The words fell.

Lu Yu walked into the jungle.

"It's very humid in the rainforest, so in order to be able to make a fire, I try to collect some dry starters and firewood. ”

"The core of the palm tree is a good choice. ”

As he spoke, he walked up to a palm tree, broke off the top leaves, peeled off the verdant bark, and took out a mass of cotton wool from it.

"It's the core of the palm tree, because it's hidden in the deepest part of the palm tree, and the core stays dry even when it's wet. ”

Putting the core of the tree into his trouser pocket, Lu Yu broke some dead branches of trees along the road, wrapped them in his jacket, and carried them back to the camp.

He then walked around the shelter again.

When he returned, he was already holding a stone with yellow-brown spots growing in his hand.

Holding the stone and shaking it in front of the camera, Lu Yu said: "You can't make a fire without the help of a blade, 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 waiting for an explanation, the people in the live broadcast room asked again:

"Stone Age?"

"How do you make a knife from a stone?"

"I think it should be possible! Otherwise, how did the ancestors survive?"

......

Looking at the stone in his hand, Lu Yu thought for a while.

Then he quickly got up, came to a rock, and after finding an angle, smashed the stone very the rock next to it.

"Bang ——!"

Moment.

Flint, torn apart.

Scattered all over the place.

After bending down and picking it out, Lu Yu picked up a fairly sharp stone chip and put it in the palm of his hand and brought it to the camera: "Look." ”

"This piece of stone, isn't it sharp? Maybe you don't believe it, but it can easily cut through my T-shirt—"

As he spoke, Lu Yu immediately demonstrated it to the audience.

Raise the stone knife and cut it lightly on your T-shirt.

Soon, the audience heard a "stab".

Looking at Lu Yu's T-shirt again, a long opening has already appeared.

Seeing this scene, everyone's eyes lit up!

Never thought that you could make a knife out of just stones?

"Damn, it looks pretty sharp!"

"Feather God, you're such a clever little ghost!"

"I said a long time ago that stones can be made into knives, and you still don't believe it!"

"A fire in the winter is given to the anchor plane× 5—— do it yourself, and you have enough food and clothing!"

"No chest, hard squeezing, giving to the anchor Super Rocket× 1—— is too good B!"

......

In front of the shelter.

Lu Yu sat on the ground.

According to the first, second and third levels of the ignition material, the size and thickness are classified one by one.

When everything was ready, he slowly spoke:

"Firewood is there, and blades are there. Next, I will show you a very primitive method of making fire - drilling wood to make fire!"

The audience in the live broadcast room is no stranger to this word.

Many people know about drilling wood for fire, and they also know the historical evolution of primitive societies.

However, in this world of extremely advanced technology, the way of making fire by drilling wood for fire is still forgotten by many people.

Almost no one has seen with their own eyes the so-called "drilling wood for fire".

The impression of drilling wood for fire is only derived from books or science and education documentaries.

If it weren't for Lu Yu's reminder, most people wouldn't have thought that he would use such a primitive way to raise a fire.

"it!"

"Drill wood for fire?"

"How is this possible, don't blow it to the anchor!"

"I've only seen in books about drilling wood for fire, and I've never seen anyone play like this!"

"Sit and wait!"

"Really, fake?"

Ignoring the barrage in the live broadcast room, Lu Yu continued:

"There are three ways to drill wood for fire, namely hand drilling, rope drilling, and bow drilling. ”

"Because of the limited conditions and time, today I will demonstrate to you the relatively simple hand drilling method. ”

"The hand drilling method is very different from the other two methods of ignition, 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 flat plank to use as a drill plank, and then we need to find a small wooden stick to use as a drill pipe. ”

Rummage through the firewood.

It took a lot of effort for Lu Yu to find a wooden board and stick suitable for use as a drill board and drill pipe.

"Wait, I need to dig a hole in the edge of the drill plate to make an ember groove that is easy for the embers to dump, and then use one end of the drill pipe to resist the ember groove and rotate it constantly, as long as I have accumulated enough embers, I can put it in the ignition and blow it to help combustion. ”

As he spoke, 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.

Because of the limitations of the tool, the shape is not very regular, but it is not a big problem.

Immediately afterwards, he found another dried leaf and put it under the hole.

"This leaf, there's a term, it's called an ember disk. ”

"When the drill pipe rubs against the drill plate, it generates a large amount of embers, which is the fuse that ignites the ignition, and the task of the ember disc is to gather the fuses together and maintain the temperature. ”

Lay out the drill plate.

Lu Yu used a stone knife to repair the drill pipe to make it more regular, and then took out the palm tree core from his trouser pocket and put it next to it for later use.

Soon.

Ready to go.

He moved his shoulders a little and aimed the tip of the drill pipe at the small hole in the drill plate.

Then, gently clamp the drill pipe with both hands and rub it back and forth repeatedly!

"Boom——!"

Time was passing minute by minute, and the live broadcast room was filled with the sound of wood rubbing.

Everyone's eyes fell on Lu Yu's hands.

"Damn, what kind of hand speed is this?"

"At least 20 years single!"

"I like the unicorn arm of the feather god!"

“233333”

"The muscles are really strong!"

As time passed, Lu Yu could clearly feel that his palm was starting to heat up!

The boreholes in the planks also rise sharply due to friction.

Gradually.

The wood begins to change color.

Through the lens, you can even see wisps of black smoke......
