I, the King is a killer

In a hurry, Xiao Yun turned on the stove regardless of the heat.

The heat wave gushed out and directly burned several of his hair.

But without fear, he was surprised and said, "the temperature is coming up!"

Ba Dao was puzzled and asked, "young master, why is this?"

Xiao Yun explained, "are you still a martial artist? How can you perceive your surroundings so slowly? Before you pull the bellows and do your best, it will take half an hour to see the sweat. After half an hour, the back of your clothes will be wet, but how long has it been now that your sweat has come down? First, you don't feel cold. Second, you don't go natural and unrestrained at night. Naturally, it's not a disease of physical weakness. It can only be because the furnace temperature rises and the heat wave leaks out. Your body feels hot! "

Ba Dao was stunned for a moment, and then immediately said, "yes, it's much hotter than usual!"

"Go on, go on, add carbon blast! It seems that the stone can be refined today! "

The most primitive smelting is actually quite simple.

In nature, metals are embedded in rocks in granular form, which can be regarded as physical fusion rather than chemical fusion and become other substances.

If it is chemical fusion, it requires some chemical reactions to extract metals, which is not what Xiao Yun can do now.

But it is still possible to extract those particles.

There are many components in stones, but most of them are things with extremely high melting point, which is easy and impossible to melt.

More than a thousand degrees, the metal melts and the stone is still intact, so the metal appears liquid, flows out of the stone and gathers, which is a less pure metal block.

It's actually that simple.

The so-called smelting technology is just to control the temperature. For example, when melting copper, let the temperature be more uniform. Don't let other metals melt and flow out together, so that the copper will be slightly pure.

Just a little.

There are many metals with melting points similar to copper. Gold is one of them, so copper is usually made of alloy.

Change a way of thinking to see, in fact, "gold and copper are not separated". I'm afraid it also exists in the form of associated minerals in nature because the melting points of gold and copper are the same!

Of course, it's all gossip.

The key is that the piece of black metal Xiao Yun got from the blacksmith's shop is already a complete piece of metal. Xingxing iron, which sounds cute, is really something out of heaven!

As long as it is melted a little, there is no need to refine, let it dissolve and easy to shape.

This actually involves the difference between "forging" and "melting".

One is high technology, the other is high technology.

There is no distinction between high and low.

The design content is somewhat complex.

Xiao Yun thought he didn't have to think about it.

Just melt it all.

But

get the opposite of what one wants!

He needs to make two pieces of metal.

One is Star iron and the other is soft gold.

It's all extraterrestrial.

The reason why the furnace temperature has to reach 1890 degrees is that the melting point of Roujin is the same as that of chromium.

Sure enough, soft gold entered the furnace, and soon the golden metal solution flowed out of the stone. It looked like life. It vibrated and flowed, and finally gathered in the crucible, as if it were beating gold, which was loved by people.

And then burn off some of the impurities, especially the melting point of some impurities is very low, resulting in their boiling point and vaporization point is also very low, so they are the same as water vapor, directly burning and flying away!

After waiting for a while, Xiao Yun took out the crucible and poured it into the long finished tank for shaping, followed by grinding, quenching and other processes.

This will be done later.

Now it is more important to melt the star iron.

But... When things go in, they just burn red and soft. If they want to melt, they are always one step away!

Xiao Yun couldn't help sighing.

This is the best stove in the Qin Dynasty. After its own transformation, it has reached the acme of science and technology in the world.

But... Still not.

However, it is a lucky thing in misfortune. If there is no chance for smelting, there will be a chance for forging!

Yes, the smelting method is very simple. Put the purified metal in the tank and shape it directly.

But if the melting point is not reached, it is impossible to melt completely, that is, how can we not raise the furnace temperature? What should we do?

And even if the melting point is reached, there is no corresponding ability to remove impurities

Even Xiao Yun's previous life was decades ago.

It's very hard. Extremely difficult!

You can't get it out with a pat on the forehead.

But before that, what should people do if they want high-performance steel? Forge!

Use craft to make up for technology.

Just like what the generals do, when they don't have enough technology and don't master new energy such as coal, they can only use extremely complicated skills to improve as much as possible.

Forging means that things are not melted and cannot be molded. What if you want to eliminate impurities? Smash! What if you want to shape? Smash!

All kinds of beating, Xiao Yun is full of strength, from day to night, and from night to day. The soft is metal, the hard is debris, and the splashing is impurities.

This came and went, and when it was time to rest at midnight on the third day, the metal finally didn't change.

Burning red, more like a piece of hot tofu.

A metal ingot weighing dozens of kilograms was smashed into ten kilograms!

And because the density of this object is too high, the remaining material is only the size of a fist.

Xiao Yun's eyes turned. He didn't eat or sleep. He forged it all night and forcibly forged it into a crescent moon.

It's called crescent knife. It's curved and has a single edge.

Other people's crescent knife is three feet long. His one is less than one foot. It looks more like a beautiful work of art.

Others have a blade on the inner side. It is used like a sickle and has excellent cutting effect.

But Xiao Yun has a blade on the outside.

When you cut something, go outside. If ordinary people use it, it will hurt the skin but not the muscles and bones.

The biggest difference is that the star iron was dark when it first appeared.

At this time, it is as white as silver!

That kind of white, white fresh and bright, white as snow and velvet!

Even Xiao Yun himself was frightened.

I don't understand why the original black metal turns white after forging, which is too big.

However, Xiao Yun didn't think much about it. At this time, when he picked it up, he had to sharpen the edge. But when he grinded, he found that only stone powder fell off the grindstone, but no meat fell off the knife!

No, where's the sharpness?

I tried several grindstones, but I couldn't grind it off. Finally, I even used diamond. As a result, the diamond didn't move, and it didn't move!

This is not to say that its hardness reaches the level of diamond, but that it has too high toughness, strength and wear resistance.

But I turned my eyes and could only burn and smash again. Using my own techniques, Shengsheng knocked out a cutting edge!

Then you don't even need quenching, and you can directly cool it.

On the other side, Roujin also cooled down, and then returned to the furnace for annealing, beating and shaping. Carefully, Xiao Yun knocked wildly with a small hammer. With a short palm sized knife, he knocked hundreds of thousands of times!

Knock it into a perfect mirror, that's all.

Look back, double knives have become!

One is as white as a crescent moon, and the other is as golden as the sunrise.

The sun and moon double blades are made here.

Better than Xiao Yun had expected.

With two knives sandwiched between his fingers, Xiao Yun laughed and was extremely satisfied.

Badao can finally rest.

He's been pulling the bellows crazy these days. He feels that his arms are not his own, and his upper body is numb!

But he also came up curiously and asked in a low voice, "young master, your knife is beautiful and thick, but it doesn't have a handle. How can you use it? If the concealed weapon is bigger... "

Xiao Yun said with a smile, "handle? It's in your own hand. The blade, as long as the blade is good. "

"Does this... Work?"

Xiao Yun smiled, his palm shook, a white awn flashed, the moon blade flew past, stabbed into the anvil next to him, and the blade point cut into the iron!

The saber glared round his eyes.

If he wants to do this, he can do it, but he needs a good knife to accumulate strength and cut it fiercely.

Xiao Yun's move is too light.

So it seems a little scary.
