Section 531

…

Thank you all for the gifts.

Lu Yu took a breath and wiped the sweat on his forehead:

"Burning charcoal is very time-consuming. Even if everything goes well, it will take at least five or six hours."

"We have to make good use of this time. Brothers, let me show you something fun. Come on!"

Nani?

Fun stuff?

After listening to Lu Yu's words, the audience instantly became energetic and kept posting comments:

"What's going on? Something fun?"

"Wash your hair upside down, or use a five-speed electric fan?"

"The whole job?"

"Anchor, please start your sexy performance!"

…

While talking.

Lu Yu pulled out a one-meter-long eucalyptus tree from the pile of firewood in the storage room.

Then he returned to the bonfire and sat on the ground.

He held the eucalyptus branch in front of his eyes and looked at it carefully.

then.

He decisively took out the stone knife, peeled off the bark, and kept fanning the bonfire.

"By fanning the bark, the temperature of the campfire can be increased..."

Before Lu Yu could finish speaking, the audience in the live broadcast room started to make noise.

They all feel that they have been tricked by Yu Shen...

"That's it?"

"Anchor, this is not fun at all..."

"Following the fire?"

"Making trouble?"

"Brothers, I think things may not be that simple."

…

Lu Yu ignored the barrage.

While fanning the bark, he continued:

"That's how the blower works."

"Using this principle, we can instantly increase the temperature of the fire by several levels!"

After saying this, Lu Yu used a stone knife to cut the bark into two parts.

It becomes two rectangles about twenty centimeters long and five centimeters wide.

then.

He then cut a 2.5cm gap in the middle of the rectangular bark and inserted the two gaps together.

At this time.

The bark turns into a cross fan blade!

After showing it briefly to the camera.

Lu Yu casually took out a small straight wooden stick.

Use a stone knife to cut a cross-shaped opening on the top of the wooden stick, and fix the fan blades on it.

Tighten with rope.

In this way, a cross-shaped simple fan is ready.

Then he placed the fan in front of him.

Hold the stick with both hands.

Use it as an axis.

Use the method of drilling wood to make fire by rubbing the stick back and forth.

In comparison, the wind power of a fan is much greater than that of tree bark.

As the fan rotates, the charcoal fire in front of you turns red and darkens.

The temperature also suddenly increased a lot.

At this time, Lu Yu finally spoke:

“This is the original blower.”

"Although the principle is quite simple, it is very practical."

"It was precisely with this thing that primitive people truly learned to 'play with fire' and mastered the technology of smelting metal tools."

At this point in the live broadcast, the audience suddenly realized that they finally understood what Lu Yu meant.

It turns out that this guy is going to build a blower!

"Anchor, you are really awesome!"

"Thief 6!"

"If a person as awesome as Yu Shen could travel back to the primitive era, he could become a god in a matter of minutes!"

"Damn it, I have to watch and study hard. I can use 233333 in case I travel through time."

"Brother, just give in to your sister-in-law, why bother!"

"Hahahahahahaha, I laughed so much that I rolled off the bed!"

"If Yu Shen had lived here for ten years, he would have been able to make a gun, right?"

"Be confident and remove the bar!"

…

Set the cross fan blades aside.

Lu Yu took some more clay from the bamboo basket and threw it on the stone slab in front of him.

First knead it into a round mud cake.

Then, take the mud material and knead it into several mud strips.

Round and round.

Carefully, I circled the edge of the mud pie.

When he finally closed his mouth, he deliberately left a long "air outlet".

It seems.

It looks like a gourd and a gourd.

The only difference is that this thing has a flat bottom compared to a scoop.

"This thing that looks similar to a chamber pot is the shell of the blower."

"Of course, this is just a prototype, and the details need to be enriched next -"

"666, is the chamber pot okay?"

"This is a live broadcast with flavor!"

"Feather God: Next, I will show you how to use this chamber pot!"

"Yes, it does have that taste!"

"I have a bold idea!"

“Kind of like Peppa Pig!”

"What a chamber pot, it's actually a shit button!"

"Fuck, brother, stop talking, I'm eating!"

…

After looking at the strange barrage, Lu Yu smiled bitterly and said:

"Brothers, can you please stop talking about such sleazy topics...I almost believed it."

As soon as I finished speaking.

There was another burst of laughter in the live broadcast room.

It took a long time to end this topic.

Subsequently.

Lu Yu used some more mud to enrich the outer wall of the fan.

Make it more rounded.

then.

In order to facilitate the entry and exit of the drill pipe, a round hole slightly smaller than a palm needs to be dug at the bottom of the mud cake.

The function of the blower is to fan the flames and increase the firepower.

Therefore, the air outlet also needs more thought to concentrate the wind force.

So, in the end, Lu Yu made another big move.

He extended the mouth of the pot by a few centimeters.
