Between words.

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

Slowly clip 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 oven.

After carefully transferring the crucible to the mold.

Lu Yu smiled excitedly at the camera:

"Brothers, keep your eyes open!"

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

After speaking.

He slanted his hand.

The copper water in the crucible flows out slowly.

All of them were poured on clay molds.

As the temperature drops, the copper water is cold and quickly condenses.

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

"This process may have to wait for a while......"

"Because kaolin is fine enough and sand-free, it is not the best casting mold for liquid metal, but it is more powerful than ordinary virgin clay. ”

"The crucible used by the ancient people to smelt copper was basically a clay melting cup, and it was not until the invention of the vertical iron-making furnace that the alchemy technology made a qualitative leap. The emergence of vertical iron-making furnaces has made Huaxia's iron-making technology at the forefront of the world, and it is no exception to this day. ”

Except for Huaxia.

Civilizations such as Indo, Babylon, Egypt, Greece and Rome have also mastered very perfect 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 comparable to modern civilization.

However, the invention and application of metal tools were of great significance at that time.

It not only greatly improves productivity, but also allows human civilization to usher in its own highlight moment and complete a qualitative leap.

It has embarked on the broad road of rapid development.

For Lu Yu, this is also a big progress!

Even though in a few days, he was leaving.

But the challenge is not yet at the last minute.

Any accident can happen......

Inclement weather.

The sea breeze that doesn't stop.

Heavy rain can pour down at any moment.

Or maybe it's a storm brewing.

Again, that's the same sentence.

Tomorrow or the accident, no one knows which will come first.

Before the mission is over, even a trivial oversight can put you in an embarrassing situation.

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

The more you get to the end, the more you have to be steady.

Because of the narrow finals, every bush will be in danger!

To put it bluntly, survival in the wilderness is the king of the leftovers.

No matter how hard, embarrassed, and unsightly it was in the early stage.

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

……

This time to wait 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 a little.

Soon, the time came to the afternoon.

After a nap.

The blade of the axe inside the mold has also cooled almost to the core.

Leaned over for a moment.

Lu Yu carefully dismantled the outermost tile mold.

First, I tested the temperature of the clay with my hands.

The residual heat is still there.

But there are no more problems.

Seeing this, he spoke:

"All right, brothers. ”

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

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

The next second.

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

The crescent-shaped curved blade is clearly visible.

Very chic.

The surface of the axe blade is uneven.

The rough meteorite pattern has a different taste.

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 little thin.

Elemental copper is already on the soft side.

This is a defect in the material itself.

If the thickness is not up to standard, it will have more or less an impact.

Secondly, it may be the cause of the mold.

The shape of the blade of the axe is not ideal.

But.

None of this is a thing.

Compared with stone axes, copper battle axes are more than enough to cope with daily production and crisis defense.

Anyway, this is also copper!

After the blade, it is definitely a weapon to take advantage of.

After picking up the axe blade, Lu Yu showed it to the audience in an all-round way, attracting countless cheers:

"Damn, did you succeed?"

"One word: handsome!"

"It's definitely a technical job!"

"It's really awesome, smelting copper with bare hands!"

"This is amazing, this ......"

"I'm a professional troll, but after watching Feather's live stream, I sealed my keyboard!"

“6666666！”

Followed by.

After the flood barrage, a wave of gifts rushed in!

"The two-faced personality gave the anchor fish ball× 1,000 —— is too good to break the groove!"

"Stealing Guevara gave the streamer a plane × 10—— this is probably the most hardcore extreme live stream I've ever seen in my life!"

"Seventy times a night without back pain, give it to the anchor Super Rocket× 10 —— is so vigorous!

"Bring a knife without an umbrella on a rainy night and give it to the anchor King Kong jumping × 10—— Nima, it's really too good~!Yushen, please take my knee!~"

This wave of ancient copper smelting has completely exceeded the imagination of the audience!

If he hadn't seen it with his own eyes, no one would have believed that Lu Yu could complete such a complex project without being armed!

These seemingly unrelated materials in front of him, after Lu Yu's ingenious workmanship, finally completed the transformation they should have!

Most of the viewers in the live broadcast room have been chasing all the way from the beginning of the broadcast to today.

I have seen a lot of difficult and bizarre experiences here.

But counting it down, it seems that there is nothing more hardcore than today's wave of operations!

A second ago, his footsteps were still stuck in the stone tool.

But in the blink of an eye, the situation changes.

The Bronze Age has arrived!

After thanking the sailors, Lu Yu continued:

"Although the hardness of elemental copper is limited, for me, this is already a great improvement ......"

I recall the difficulties I had at the beginning of my landing.

And the desire for cutting tools!

Lu Yu's voice was choked, and his eyes were red.

I felt a lot of emotion in my heart.

"Brothers...... I once said a word. ”

"I'm willing to trade all my supplies and food for a Swiss Army knife......"

"Now, although a saber is not possible, a Viking tomahawk is also very important to me, not just to live better...... It is the reward of my hard work, and it is also the greatest result of my extreme survival for more than 50 days. It's so rare......"

Lu Yu's mood is very understandable to sailors.

This bronze axe, in a sense, has gone far beyond its own value.

More than just a testimony.

It's also an honor.

This time, in the process of fighting against nature with his bare hands, Lu Yu went down first!

Against all odds.

Created a beautiful chapter that belongs to this era!

And this bronze axe blade is the spoils of war that he gambled his life for!

——————————

PS: In the past few days, the pain in the cervical spine has been severe, which once spread to both shoulders and back, and my hearing has also been affected.

Ran to the hospital twice.

Constant renewal is the limit.

Also, the desert island dungeon is coming to an end soon.

The next plot has to be sorted out.

Feel relieved.

Even if you can't get out of it, you absolutely guarantee that there will be a change every day.
