The Ultimate Live Superstar - Chapter 397
Speaking room.
Lu Yu found two bamboo billets from the wood pile and dived into the furnace.
Slowly pinch out the red clay pots.
The hot copper water in the pot was covered with a thin layer of gray impurities as soon as it came out.
After carefully transferring the crucible to the mold.
Lu Yu smiled excitedly at the camera:
“Brothers, keep your eyes open!”
“The moment to witness the miracle is coming…”
Finished.
He tilted his hand.
The copper water in the crucible slowly flows out.
It’s all poured on the clay mold.
As the temperature drops, the copper water meets cold and quickly condenses.
“When the copper water is completely cooled and hardened, you can go to the mold.”
“This process may have to wait for a while…”
“Since kaolin is fine enough and free of sand, it is not the best casting mold for liquid metals, but it is also stronger than ordinary raw clay.”
“The crucibles used by ancient people to make copper were basically clay pots. Until the invention of the vertical iron-making furnace, the qualitative leap in gold-making technology appeared. The emergence of the vertical iron-making furnace has made Huaxia’s iron-making technology always in the top The forefront of the world is no exception to this day.”
Except for China.
Civilizations such as Indu, Babylon, Egypt, Greece and Rome have also mastered very perfect casting techniques.
Most early castings were made of gold, silver, copper and their alloys.
Discussing casting technology alone, although not as good as modern civilization.
But the invention and application of metalware was of great significance at the time.
Not only has productivity greatly increased, but human civilization has also ushered in its own moment of glory and completed a qualitative leap.
Embarked on the Kangzhuang Avenue of rapid development.
For Lu Yu, this is also a big improvement!
Although within a few days, he will leave.
But the challenge has not yet reached the last moment.
Any accident can happen…
Bad weather.
Unbearable sea breeze.
Heavy rain pouring down at any time.
Or a storm that is brewing.
Again.
Tomorrow and accidents, no one knows which will come first.
Before the task is over, even a trivial negligence can put yourself in an awkward position.
For a person who has died once, Lu Yu knows this better than anyone.
The more the last, the more stable it is.
Because of the narrow finals, every grass will be in danger!
The wilderness is plain, that is, the left is king.
No matter how hard, how embarrassed, how unsightly.
People can only remember the last one to live.
…
Wait for this time for the mold to cool.
Lu Yu first went to the river to fetch water, and then casually ate something to replenish his energy.
Soon, time came to the afternoon.
After a short nap.
The axe blade in the mold has also cooled almost.
Leaned over and looked at it for a while.
Lu Yu carefully disassembled the outermost tile mold.
First try the temperature of the clay by hand.
The remaining heat is still there.
But there is no problem.
Seeing this, he said:
“Okay, brothers.”
“Look at the effect…”
With that said, he broke the hardened clay around the edge of the axe and took out the axe inside!
Next second.
The texture and halo of simple copper appeared in front of the camera quickly.
The crescent-shaped arc blade is clearly visible.
Very chic.
The surface of the axe blade is uneven.
The rough meteorite pattern, don’t have a taste.
Of course, there are many shortcomings.
First of all, because there is not much copper material, the thickness of the axe blade is only more than one centimeter.
It looks a little thin.
Elemental copper is inherently soft.
This is a defect of the material itself.
If the thickness no longer meets the standard, it will have some effect.
Secondly, it may be the cause of the mold.
The shape of the axe blade is not ideal.
but.
These are not things.
Compared with the stone axe, the copper battle axe is more than enough to deal with daily production or crisis self-defense.
Anyway, this is also copper!
After the cutting edge, it is definitely a handy weapon.
After picking up the axe blade, Lu Yu showed it to the audience in all directions and attracted countless applause:
“Slot, succeeded?”
“One word: handsome!”
“Absolutely a technical job!”
“True TM is amazing, making copper by hand!”
“This is amazing, this…”
“I was a professional web sprayer, but after watching the live broadcast of Yushen, I sealed my keyboard!”
“6666666!”
Immediately.
After the flood-like barrage, a large wave of gifts flew!
“Two-sided personality presented to the anchor fish ball × 1000!-Tai Niu broke the trough!”
“Stealing Guevara as a gift to the anchor plane × 10!-This may be the hardest core live broadcast I have ever seen in my life!”
“Seventy times a night, don’t hurt the waist and give it to the anchor Super Rocket × 10!-It’s so fierce! Copper can be refined by itself!”
“Rainy Night with a knife and no umbrella is given to the anchor King Kong Jump × 10!-Nima, it’s really awkward~! Yushen, please take my knees!~”
This wave of ancient copper smelting has completely exceeded the imagination of the audience!
If it weren’t for seeing it with one’s own eyes, no one would believe that Lu Yu was able to complete such a complex project under the defenseless situation!
The seemingly unrelated materials in front of me, after Lu Yu’s ingenious work, finally completed the transformation he deserves!
The vast majority of the audience in the live broadcast room is mostly chased from the beginning of the broadcast to today.
I have also read a lot of hard and bizarre experiences here.
But after counting down, there seems to be nothing harder than this wave of operation today!
One second before, when the footsteps were still on the stone tools.
In an instant, the situation changes.
The Bronze Age has arrived!
Thanks to the water friends, Lu Yu continued:
“Although copper has limited hardness, it has been greatly improved for me…”
Recalling the difficulties at the beginning of landing on the island.
And the desire for cutting tools!
Lu Yu’s voice choked with sore eyes.
A lot of emotion in my heart.
“Brothers…I once said a word.”
“I am willing to use all my supplies and food in exchange for a Swiss army knife…”
“Now, although the saber is impossible, a Viking battle axe is also very important to me, not only is it better to live better…it is the reward of my hard work, and it is also my ultimate survival of more than fifty The greatest achievements of heaven. This is so rare…”
The friends of Lu Yu understood the mood of Lu Yu very well.
In a sense, this copper axe is far beyond its own value range.
Not just a testimony.
It is also an honor.
This time, in the process of confrontation with nature, Lu Yu first went to the city!
Overcome all difficulties~www.mtlnovel.com~ Created a unique chapter in this era!
And this copper axe is exactly the spoils of his bet!
