The Ultimate Live Superstar

"Even if everything goes well, it may take another hour."

"During this period, you must keep an eye on the furnace temperature. If necessary, add charcoal in time..."

The words fell.

Lu Yu summoned the drone in front of him, pushed the camera closer, and took a picture of the situation inside the fireworks.

The system's drone is made of special materials.

Not afraid of high temperatures.

Even extremely violent means cannot destroy it, let alone the furnace fire of 1,800 degrees, even if it is probed into the magma, it is a trivial matter.

The next second.

After the camera zoomed in.

The audience clearly saw the changes in the copper material in the crucible!

It was amazing!

"6666666666666"

"It really melted!"

"Fuck, awesome!"

"Isn't Yu Shen's drone too hardcore? It's okay to stick it into the fire?!"

"After all, it's exclusive to the rich!"

"I feel that the drone is still more awesome!"

"233333333"

...

Soon.

Another hour passed.

During this time, in addition to chatting with the audience, Lu Yu added another batch of charcoal to the furnace.

At this moment.

The continuous high temperature finally burned the crucible red, which was very eye-catching.

And the copper material inside seemed to have turned into water.

Seeing this scene.

Lu Yu wiped the sweat from his forehead and said:

"It's basically done when it burns to this degree."

"Okay, next, let's find something to clamp the crucible out, and then pour the copper water inside on the clay mold-"

)

While talking.

Lu Yu found two bamboo blanks from the firewood pile and probed into the furnace.

Slowly clamped out the red clay crucible.

The boiling copper water in the pot was covered with a thin layer of gray impurities as soon as it came out of the furnace.

After carefully transferring the crucible to the mold.

Lu Yu smiled excitedly at the camera:

"Brothers, open your eyes!"

"The moment to witness the miracle is coming..."

After saying that.

He tilted his hand.

The copper liquid in the crucible slowly flowed out.

All of it was poured on the clay mold.

As the temperature dropped, the copper liquid quickly solidified when it was cold.

"Wait until the copper liquid is completely cooled and hardened, then you can remove the mold."

"This process may take some time..."

"Because kaolin is fine enough and has no sand particles, it is not the best casting mold for liquid metal, but it is better than ordinary raw clay."

"The crucibles used by ancient people to smelt copper were basically clay melting cups. It was not until the invention of the vertical iron smelting furnace that alchemical technology made a qualitative leap. The emergence of the vertical iron smelting furnace has kept China's iron smelting technology at the forefront of the world, and it is no exception today."

In addition to China.

Civilizations such as India, Babylon, Egypt, Greece and Rome have also mastered very complete casting technology.

Most of the early castings were made of gold, silver, copper and their alloys.

In terms of casting technology alone, although it is not as good as modern civilization.

But the invention and application of metal tools were of great significance at the time.

Not only did it greatly improve productivity, but it also brought human civilization its own highlight moment and completed a qualitative leap.

It embarked on a road of rapid development.

For Lu Yu, this is also a big step forward!

Although I will leave in a few days.

But the challenge has not yet reached the last moment.

Any accident may happen...

Bad weather.

The sea breeze that can't stop.

Heavy rain that can pour down at any time.

Or a storm that is brewing.

Again.

Tomorrow and accidents, no one knows which will come first.

Before the mission is completed, even a trivial negligence can put oneself in an embarrassing situation.

For a person who has died once, Lu Yu knows this better than anyone else.

The closer you get to the end, the more you have to stay stable.

Because in the narrow final circle, every bush will be full of dangers!

To put it bluntly, survival in the wilderness means survival for the last one standing.

No matter how difficult, embarrassing, or unsightly the early stage was.

People can only remember the one who survived to the end.

…

During the period of waiting for the mold to cool down.

Lu Yu first went to the river to fetch water, and then ate something casually to replenish his energy.

Soon, it was afternoon.

After a nap.

The axe blade in the mold was almost cooled down.

He leaned over and looked for a while.

Lu Yu carefully disassembled the outermost tile mold.

He first tested the temperature of the clay with his hands.

The residual heat was still there.

But there was no problem.

Seeing this, he said:

"Okay, brothers."

"Let's see how it works..."

As he said that, he broke up the hardened clay around the axe blade and took out the axe blade inside!

The next second.

The texture and halo of the single copper soon appeared in front of the camera.

The crescent-shaped arc blade was clearly visible.

Very unique.

The surface of the axe blade was uneven.

The rough meteorite pattern has a unique flavor.

Of course, there are many disadvantages.

First of all, because there is not much copper, the thickness of the axe blade is only more than one centimeter.

It looks a bit thin.

Copper is soft.

This is a defect of the material itself.

If the thickness does not meet the standard, it will have some impact.
