Seeing that the bronze Buddha entered the iron box and was about to ignite the fire, Li Zhang asked in a trembling voice: "It's really... going to melt?"

This is a statue of god...

Are you not afraid of the gods and immortals punishing you?

Li Chengzhi almost threw the clay on Li Zhang's face.

I took off my pants, tell me this?

He glared at Li Song fiercely: How did you do ideological mobilization?

Li Song cursed with hatred, "How did you tell me before? If you don't refine this bronze statue, where did you get the iron forging armor? Could it be that you will rush to the formation with your shirtless?"

Shirtless?

Li Zhang lowered his head and said with a roar of roar, "It's not impossible!"

"Bang!"

Li Song threw the clay tablet in his hand over and hit Li Zhang's head accurately: "It's okay to make you stupid... It doesn't matter if you die, grandpa, what about your uncle, what about your brother? How many bottles of dead objects are more important than the lives of your closest relatives?"

Seeing his father getting angry, Li Zhang hugged his head and didn't dare to say anything.

It's still people of his age who understand him.

Li Liang hugged his shoulder and muttered in a low voice: "My Li family started with military merits and only served as the military leader (Chiyou). When did you believe in this mud-shaped copper-cast mortal? Besides, didn't you still yell yesterday that you wanted to ask your husband to give you a sharp weapon like the fourth uncle (Li Song)? If you don't melt this copper, what should you use to exchange iron materials and what should you use to buy mulberry gun rods?"

Listening to the first half of the sentence, Li Zhang was still indifferent, but when he heard the second half of the sentence, his eyes were like electricity, and it suddenly lit up.

What about Sangtuo Muka's spear?

"Well...then melt..."

Li Song's face turned blue with anger.

It sounds like you said you didn’t melt, but today it won’t melt?

Just as the husband said: I really itchy...

Li Song thought that there would definitely be people questioning, and there were indeed some questions: such as younger brother Li Bai and cousin Li Feng.

After all, this is a god and a Buddha. Anyone will have a sense of awe, including him.

As for Li Chengzhi?

Most of the time, Li Song disregarded him...

When Li Song said, "I can't say that these wealth will be the foundation of my Li family's uprising." Li Bai and Li Feng were like Li Zhang in front of him, his eyes lit up...

If one day you really succeed, this will be a matter of shining for generations and honor, and you are still afraid of how many bottles of Buddha will be melted?

But Li Song didn't expect that Li Bai and Li Feng could understand Li Zhang, who was obedient to him on weekdays, was reluctant?

Fortunately, I didn’t bring Li Xian, otherwise I would have to jump up!

Two idiots...

Although Li Zhang is straight-hearted, he is very strict. Besides, with Li Song pressing him down, he definitely dare not speak nonsense.

Seeing that he stopped talking, Li Chengzhi didn't comment anymore.

He quickly filled the clay, sealed the box, and instructed Li Zhao and Li Ming to add coke to the furnace.

The process is actually very simple, much easier than steelmaking. Just be careful not to be too high, don’t refine the iron box, and wait until the copper juice is drained and overturned the iron box, don’t smash the pottery fen inside...

Not long after it burned, the burning liquid flowed out of the pottery ditch at the bottom of the blast furnace.

The furnace temperature at this time is only three to four hundred degrees, so where can I melt the copper?

This is the tin and lead inside copper.

After the clay was dried, the furnace was resealed, and less than half an hour later, a large amount of copper juice flowed out.

Li Chengzhi immediately stopped two windmills, leaving only two, and evenly simmered the wind in.

After two moments, Li Chengzhi breathed a sigh of relief when he saw the thin iron bars inserted into the chimney standing straight.

The temperature control is pretty good...

Li Song took Li Feng and his three nephews to quickly move the steel plate with mud sticks, carefully allowing the copper juice to flow into it, trying not to waste a drop.

Each steel plate is one foot square, with ten clay molds neatly attached to it. The copper ingots cast from each clay mold are roughly ten kilograms.

This template can cast 100 kilograms of copper. Li Chengzhi used up all the steel he refined in the past two days and night, and only barely made 100 pieces.

After using these templates, they were only about 10,000 kilograms, so he never wanted to leave a little copper slag for the monks from beginning to end...

As the flames went out, the surface of the copper ingots in the mud sphere slowly turned black. Li Chengzhi asked Li Song and others to quickly smash the mud ingots and poured all the copper ingots into the pool next to them.

There was a boiling sound in the pool, and mist rose all over the sky.

Li Bai asked in confusion: "Langjun, why does copper also need to be quenched?"

"What kind of quenching? This is copper washing!" Li Chengzhi replied lightly, "Didn't you see that the copper that just burned is all black?"

Can it be washed with water?

Everyone thought it was strange and admired Li Chengzhi even more: Mr. Lang knows so much!

Li Chengzhi couldn't explain to them what "copper oxide hydrogen reduction" means.

In fact, this way, it cannot completely wash the black surface of the copper ingot. Li Chengzhi's main purpose is to make the copper softer, so that when you start, you will know that this is pure copper without lead-doped.

When the fog was gone, he pointed at Li Zhang and used his claw fence to fish out all the copper ingots, and ten copper ingots were neatly placed in front of Li Chengzhi.

Under the reflection of the torch, each piece exudes an intoxicating brilliance.

Except for Li Chengzhi, there are one counts one, and everyone can't stop their heartbeat and breathing is worsening.

It’s not that they have never seen copper, but that they have never seen such beautiful copper.

Nonsense, can it be not beautiful? It’s gold-filled...

The two have similar melting points, so it is very troublesome to refine them alone. Another gold content is not much, so Li Chengzhi just did it.

What is refined in this way is called bonus, also called rose gold...

However, there is only one side of each piece of copper that is of this color, while the other five sides are still red and black.

Anyway, they were going to spend it soon, but Li Chengzhi was very calm and ordered Li Song and others to take copper juice, quench water, and catch copper ingots in an orderly manner.

An hour later, no copper liquid flowed out of the pottery ditch. Li Chengzhi immediately stopped the bellows and counted the cast copper ingots.

The fourth template has just been used up, with about 400 kilograms of copper ingots and about 300 kilograms of tin and lead.

Li Chengzhi's face was a little dark.

Is this equivalent to just half the copper content?

The monk who has lost his heart even cheated on the Buddha?

The others didn't speak, just looked at him quietly.

They had advised Li Chengzhi before, no matter whether he was lead or tin, what was melted out, wouldn’t it be enough to cast it all for him?

It was Li Chengzhi who insisted on refining pure copper.

But the loss is not large.

The color of the copper ingot is so bright that as long as you know that it is mixed with gold, the price will not be much worse even if it cannot double the price of 37 bronze...

Next, the most critical step is: cast iron statue.

This is related to whether Li Song and Li Bai, Li Feng, will the backbone of the Li family like Li Feng support him in melting all these bronze statues, so Li Chengzhi was particularly serious.

He used iron chains and leverage to turn over the iron boxes to confirm that the model was not damaged. Li Chengzhi commanded Li Zhang and Li Liang to pour the refined iron juice into it.

The ceramic column used as an inner mold is a bit large, so after filling thirteen crucibles, the iron box is full.

He calculated that he would only be four hundred pounds if he had to die.

Save a little bit...

Half an hour later, when he put down the iron box and smashed the pottery film, he saw the true appearance of the iron statue, Li Chengzhi laughed like a nervousness.

Not to mention facial features, even the lines of the bun and the folds of the clothes are exactly the same...

Li Song and others were even more excited and could not speak.

What the husband said is exactly the same?

This is tens of thousands of kilograms of copper...

...

When the second attendant statue melted, the sky was already light.

In case someone spyed, Li Chengzhi asked several younger generations to sleep directly in the hall, and asked Li Song, Li Bai and Li Feng to pack the cast copper ingots.

He counted and it was only eight hundred kilograms.

At this ratio, you can get at most more than 6,000 kilograms of copper in the end.

But it is enough to deal with the current difficulties.
