The Ultimate Live Superstar - Chapter 393

Carry a bamboo basket.

Come to the river.

Lu Yu quickly found the borrow point of the last earthen kiln.

Because it just rained a few days ago.

The soil layer has been loosened a lot.

Only for a while.

It was a basket full of buckles.

“Copper smelting requires charcoal, in addition to temperature, there is an important reason -“

After finishing the harness, Lu Yu carried the bamboo basket full of clay on his body.

Swept across the muddy clay layer in one fell swoop.

Say while walking:

“That is, charcoal can be used as a reducing agent.”

“It can reduce the copper in copper oxide very well.”

“And this is the key to copper smelting by fire.”

“This method has been around since ancient times. To this day, there are still many professional smelters who will choose high-quality charcoal during their operations. The reason is this.”

“If you want to separate the copper in the ore powder, charcoal is essential.”

“In this way, how to obtain better quality charcoal has become the first thing we should consider now.”

Speaking of which.

Lu Yu secretly patted the bamboo basket behind him, and gestured to everyone:

“The clay can help us.”

“With it, we can try to build a reusable charcoal kiln for burning charcoal, and with the charcoal kiln, this problem will naturally be solved.”

These original technologies that Lu Yu talked about are unheard of to most people in front of the screen.

Curious at the same time.

Everyone heard the fog and kept asking questions in the barrage.

See the water friends so enthusiastic.

Lu Yu smiled and explained:

“It may be complicated to say, but it is actually very simple. Don’t worry, it will be clear later.”

…

All the way back to the camp.

Lu Yu put down the clay.

Come directly to the storage room.

A lot of firewood was collected and placed next to the earthen kiln.

Then he chose an open space about the size of an earthen kiln and started planning.

“This is it.”

“The first step in making a kiln is to pile these firewood into a cone.”

Talk and do.

It took less than five minutes.

He piled up the pre-prepared firewood into a slender pyramid.

“Eucalyptus branch is a very good raw material for charcoal production. As long as it is handled properly, the burned charcoal will be perfect, both hard and durable.”

“Of course, it is possible to use ordinary tree branches, but the effect will definitely be greatly reduced.”

After the wood pile has a preliminary large size.

Next, as long as you follow this shape, add firewood one circle at a time.

this work.

It seems quite simple.

But in fact, it is very particular.

It is necessary to allow the firewood to keep enough clearance, and at the same time, it must not be too loose.

Because of the stacking of wood piles.

Will directly affect the success of firing.

If the gap is too large.

The branches are difficult to fully burn, and the yield rate will be greatly reduced.

But too loose and too full burning will not work.

In order not to affect the yield, Lu Yu spent only half an hour to complete the process of stacking wood piles.

The pile of wood is more than a meter high.

It covers almost two square feet.

The bottom end is round.

From a distance, it looks a bit like a fire pit.

But it is more particular than the general fire.

The branches are next to each other.

Very neat.

“Okay, almost…”

“With a pile of wood, the next thing to do is to use clay to enclose them circle by circle to make a kiln shape.”

“It should be noted that the mud layer should not be too thick, just like the palm of the hand, try to keep the interval between one centimeter and two centimeters.”

Clay by the stream.

The humidity is just right.

It can be used directly without secondary processing.

Save a lot of things.

If it is dry clay, it may be busy.

Just the link with mud is enough to torture people.

After a brief chat, Lu Yu was busy again.

Drag the bamboo basket to the side.

Take out the clay.

Along the edge of the pile, pile up one circle after another.

It’s like building a clay kiln.

The whole process has nothing to say.

After a while, it wasn’t until the seal was about to begin that Lu Yu spoke again:

“There is an opening at the top of the charcoal kiln that cannot be completely sealed.”

“The size of the opening depends on the size of the pile of wood. There is no established standard, just grasp it yourself.”

to here.

The prototype of the entire charcoal kiln is ready.

From a distance, it looks like a small earth bag.

Very interesting.

However, this is not over yet.

For a complete charcoal kiln, it is necessary to open a vent at the bottom to plan a “door line”.

The vent is to facilitate the observation of the burning speed of charcoal and to facilitate timely blocking.

And the door line.

After the charcoal is burned, the wall of the kiln can be easily lifted to remove the charcoal.

These two details are equally important.

Especially the vents on the chassis are not impossible.

…

At the bottom of the charcoal kiln, after buckling four vents.

Lu Yu took out the stone knife again and drew an arched arc outside the kiln wall.

“Feather God, why is this used?”

“Ghost knows!”

“Xianshu?”

“You can recognize this formation?”

After glancing at the barrage, Lu Yu shook his head and explained:

“Brothers, this is the goal line.”

“After the charcoal is burned, the kiln wall will become very hard.”

“If you don’t want to damage the kiln itself, it’s a technical job to take out the charcoal.”

“So, the door line has its place.”

“At that time, as long as you gently touch it, the kiln wall will collapse along the outline of the door line, which is very convenient. The most important thing is that it will not affect the subsequent use of the earthen kiln.”

When the audience heard it, they suddenly realized that Lu Yu was a little ghost!

“6666!”

“Show!”

“Precautions!”

“Show me scalp numbness!”

…

After the charcoal kiln is done.

Lu Yu took the fire in the fire and placed it in the upper opening.

The wood pile wrapped in charcoal kiln was lit.

Supporting the kiln wall.

Lu Yu blows up the combustion, while holding back the thick smoke, squeezing his eyebrows and saying:

“At that time, the fire will burn down from the opening.”

“The opposite of the upward airflow.”

“After a period of combustion, when the fire is transferred from the top to the bottom, the firewood in the kiln will be converted into charcoal.”

quickly.

When the fire spread completely, the fire above the pile became bigger and bigger.

Seeing this, Lu Yu then explained:

“The flame above the wood pile is volatile gas, and CO and H2 are burning. If you can see these gases, it means that the temperature in the kiln is changing. This is normal.”

With that said, he controlled the drone again and flew it to the bottom vent of the charcoal kiln.

“There is nothing that needs special attention during the entire firing process, but one thing to note is that you should observe the vents every once in a while. If you can see the flames at the vents, you must use it for the first time. Clay blocks all air inlets, including the opening in the top of the charcoal kiln. When the temperature is completely cooled, the charcoal is burnt.”

“666666!”

“Lying trough, the anchor is so professional!”

“Brother is stable!”

“I’m very curious. Where did the feather **** learn from this, this bizarre knowledge?”

“interesting!”

“The volatilized ash fertilizer will be blackened and presented to the anchor plane × 1!-Powerful!”

“The invincible two devil animal king gave the anchor energy drink × 1!-666, it’s too bad!”

…

Thank you for your gift.

Lu Yu gasped and wiped the sweat on his forehead:

“Burning charcoal is very time-consuming, and it will take at least five or six hours even if everything goes well.”

“This time, we have to make good use of it. Brothers, show you something fun, Comeon!”

Nani?

Something fun?

After listening to Lu Yu’s words, the audience instantly became energetic and kept barraging:

“What’s the situation? Fun stuff?”

“Inverted shampoo, or a five-speed electric fan?”

“The whole job?”

“Anchor, please start your sultry performance!”

…

Speaking room.

Lu Yu drew a eucalyptus tree more than one meter long from the firewood pile in the storage room.

Then I went back to the campfire again and sat on the floor.

The eucalyptus branch in his hand was carefully examined in front of his eyes.

then.

He took out the stone knife decisively, peeled off the bark, and incited against the campfire.

“By inciting the bark, you can raise the temperature of the campfire…”

Before Lu Yu finished speaking, the audience in the broadcast room became noisy.

I feel like I’m being fooled by Yushen…

“this one?”

“Anchor, this is not fun…”

“Inflammation?”

“Fuck things?”

“Brothers, I think things may not be that simple.”

…

Lu Yu did not ignore the barrage.

While inciting the bark, he continued:

“This is the principle of the blower.”

“Using this principle, we can instantly increase the temperature of the fire by several grades!”

After all, Lu Yu used a stone knife to divide the bark into two.

It becomes two rectangles about 20 cm long and 5 cm wide.

then.

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

At this time.

The bark becomes a cross-leaf!

After a small show to the camera.

Lu Yu brought a straight wooden stick with him.

Using a stone knife on the top of the stick, split a cross-shaped opening to fix the fan blade on it.

Tighten with rope.

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

Then he put the fan in front of him.

Hold the stick with both hands.

Use it as the axis.

Rub the sticks back and forth by drilling wood for fire.

In contrast, the wind power of the fan is much larger than the bark.

As the fan turned, the charcoal fire in front of him turned red and dark.

The temperature also suddenly increased a lot.

At this time, Lu Yu finally said:

“This is the original blower.”

“Although the principle is simple, it is very practical.”

“It is also with this thing that the original talents really learned to’play with fire’ and mastered the technology of smelting metal.”

When the live broadcast came here, the audience suddenly realized that they finally understood the meaning of Lu Yu’s words.

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

“Anchor, you are so amazing!”

“Thief 6!”

“Awesome characters like Feather God, if you go back to the primitive era, you can be a **** in minutes!”

“Lying trough, I have to take a good look at it and learn it. I can use 233333 in case of crossing.”

“Brother, you should be soft with your sister-in-law, why not!”

“Hahahahahahaha, I laughed off the bed!”

“If Feather God has been here for ten years, can even a gun be made?”

“Be confident, remove it!”

…

Set the cross leaf aside.

Lu Yu took some clay from the bamboo basket and fell on the slate in front of him.

First, knead it into a round mud cake.

Then, take the mud and rub it into several sticks.

Circle by circle.

Carefully surrounded the edge of the mud cake.

When he finally closed his mouth, he also deliberately left a long “outlet”.

Looks.

It looks like a gourd scoop.

The only difference is that the bottom of this thing is flat compared to the scoop.

“This thing that looks similar to a night pot is the shell of the blower.”

“Of course, this is just a prototype, and then we need to enrich the details -“

“666, is the night pot OK?”

“This is a tasteful live broadcast!”

“Feather: Next I will show you how to use this chamber pot!”

“Yes, it does have that taste!”

“I have a bold idea!”

“It’s a bit like Peggy!”

“What a night pot is actually a **** button!”

“Don’t talk, brother, don’t say it, I’m eating!”

…

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

“Brothers, can’t you talk about this kind of tasteful topic…I almost believed it.”

Just finished.

There was another laugh in the live broadcast room.

It has been a long time before this topic has ended.

Then.

Lu Yu used a part of the mud~www.mtlnovel.com~ to enrich the outer wall of the fan.

Make it more mellow.

then.

In order to facilitate the entry and exit of the drill rod, the bottom of the mud cake also needs to dig a round hole slightly smaller than the slap.

The role of the blower is to incite the wind to ignite and increase firepower.

Therefore, the air outlet also needs to spend more time to concentrate the wind.

Therefore, at the end of the final, Lu Yu made a surprise.

Extend the spout a few centimeters.

Made into a funnel-shaped cylinder.

“Well… if conditions permit, it is better to fire it, which will be more durable. If it is not available, it can be used directly, but before use, it is best to dry by the fire.”

Having said that, Lu Yu took the fan blade he had made and placed it in the fan casing.

And upside down the shell.

At this time, the drill rod on the fan blade can just pass through the round hole at the bottom.

As long as the drill rod is rubbed, the wind generated by the fan blades can be blown out along the mouth of the fan.

Then warm up the fireworks!

In order to prove the feasibility of the fan, Lu Yu gripped the drill pipe and roughly demonstrated it to the audience.

“Hoohoo!”

result.

As expected.

With the rotation of the fan blades in the fan, the flame of the bonfire burns more and more.

The sound of whistling!

Very rhythmic!

Seeing this scene in front of them, the audience shined.

One after another launched the barrage:

“666666666666666!”

“Trenching, there is such awesome operation!”

“Nima, the blower is done!”

“Anchor, were you the leader of the Mingjiao Fire Banner in your last life?”

“Bright blind my titanium dog eyes!”

“Awesome!”
