I, the King is a killer

Xiao Yun sighed.

He likes the woman in his arms from the bottom of his heart.

In fact, in terms of emotion, Xiao Yun seldom reveals his inner thoughts.

It makes him sometimes seem ruthless.

Whether it's Linglong or fox eye, I always think this guy's heart is made of iron.

No matter how good he was, he looked unmoved.

But in fact, heart is not action.

Even the expression will not change at all.

It's not Xiao Yun pretending to be cold.

He's just afraid.

What he was not qualified to have is now in front of him, and he dare not take it.

Emotionally, he is a poor man.

But being poor doesn't mean he won't do anything.

The way he expresses his feelings is different from others.

He likes a person and wants to do something for her.

Secure protection and make each other happy.

In this way, Xiao Yun is very happy.

Unspeakable strange feeling.

Xiao Yun even felt that he might have the potential to lick a dog.

With a bitter smile, I can only wait quietly.

When Tuoba tianer was tired of crying.

Just take her back to bed.

Just lying down, she soon fell asleep.

Obviously, she was tired during this period, which had consumed her physical strength.

Leng Yueling sighed and said, "I'm really a poor man. The days between the cracks are the hardest."

Xiao Yun nodded and looked at Leng Yueling.

Leng Yueling said with a smile: "I don't care. I should give it back to the state of Qin. I have returned it. I am worthy of the country and the family. I am clear. I can always have my own choice."

Xiao Yun nodded again.

Yeah.

Leng Yueling has paid off. No one can say that she has not paid off.

In her good years, she was injured, scarred and imprisoned for years... She gave everything she could give back to her family, country and the world.

In the next days, she should live for herself.

She earned it herself!

She went over and put her arm around her shoulder until she leaned against herself.

"At the first meeting, although you were gentle, there was a dead breath in your eyes, which was like the interruption of the vitality of your soul. Now it's different. "

Leng Yueling was obviously stunned for a moment. Recalling the past, she suddenly smiled.

"It's also a good thing."

I just don't know how good it is.

……

The two women were resting.

Xiao Yun teaches the villagers forging outside.

Forging.

It is a traditional steelmaking technique.

Steelmaking is very difficult. It needs higher furnace temperature and more impurity removal technologies. It needs to involve something at the chemical level.

Xiao Yun doesn't have the ability to achieve it overnight.

Even if it is a simple forging, its emergence is not so easy.

For hundreds of years, even thousands of years, countless craftsmen have worked hard and devoted themselves to professional research. Every progress is the result of hard work.

They have no way to know the principle or the microstructure.

You can only think of one way, just try one.

Every new technology has to go through countless years of testing and dissemination.

Such as forging.

As the most suitable smelting means of cold weapons, it has not changed for a thousand years!

It's called ancient forging with a slightly better name.

It's better than ever, that is, there has been a certain improvement in raw materials, chemistry and furnace temperature.

But the truly epoch-making thing has not yet come.

Someone tried.

And it worked.

In previous lives, there were many new ways to make metal, and some other materials different from metal were used to produce tools.

But

If you want to popularize it, it will not take a year or two. Even in a rapidly developing society, it will not be possible to do it for decades.

But it also shows from another aspect that ancient forging is indeed the most reliable means of making weapons and can stand the test of the times.

As a killer, Xiao Yun has to make some handy weapons for himself from time to time. Naturally, he knows this skill very well.

There are several ways to clamp steel alone.

Now, what Xiao Yun taught them is the simplest one.

"This iron embryo is the blade body. First, it is much easier to make the basic shape of the blade, such as a kitchen knife. Just see the square. But if it is a weapon blade, it needs to have requirements for length, width and thickness, even weight and center of gravity. Then when the embryo is formed, it is necessary to start the layout and design, such as the dagger made now."

Xiao Yun knocked on the red iron for a few times.

The color of the iron block that has been forged into steel is very conspicuous. It even looks a little pink and tender. It looks very cute. People want to touch it.

Of course, this one can burn two fingers.

Xiao Yun beat it a few times and made it into the shape of a dagger.

"The current style is just the foundation. You see, its thickness is here. If you want to reach the thickness required by the dagger, you have to flatten it. Then the blade will become longer, wider and longer. We can cut off the long one, but it's very troublesome to trim the wide one. Therefore, when you knock, pay attention to the width and stretch it as long as possible. Of course, in this process, we must pay attention not to use too much force. When beating, we must step by step, because steel also has lines, like wood as stool legs, whether to use vertical lines or horizontal lines, which will completely affect the service life of a chair, and the lines of metal are not as easy to see as wood, This depends on experience, and the first step is that we should know in mind how many times we have broken it, how thick each time, whether it is uniform, which hammer falls hard, and how to repair it. We should know in mind and remember it well, so as to master its grain. Do you understand? "

The most important thing to forge a weapon is the grain.

Xiao Yun couldn't tell them in detail about the micro molecular structure. They couldn't understand it. Instead, they were afraid of hands and feet.

The villagers listened with their ears pricked.

Very serious.

Of course, most of what Xiao Yun said goes in the left ear and out the right ear. It's not that they don't want to learn, but... Due to talent.

"When it is formed, we need to clamp good steel. The forging of good steel is the most difficult. Good steel is the top priority for the quality of the same knife!"

A piece of scrap iron, which can definitely be called scrap iron, needs to be "refined" to be refined into steel.

The so-called refining into steel.

This refining does not mean burning, nor does it mean that iron will become steel after burning a hundred times.

Refining is a process.

Burn soft, decarbonize, anneal, forge, cool, burn, decarbonize again, anneal, forge, burn again

The most rotten iron, so a hundred times, can become steel!

And the formed steel is still high carbon steel!

Just so desperate.

After all, the way to remove impurities in the world is really limited.

Of course, there are magic weapons in this world.

But none of those things is not iron ore itself!

That's not a problem in a million. It's not easy for a mine to produce such a perfect ore.

For example, Uzi steel in the previous life is a ready-made good steel. It is not only more refined than Bailian, but also contains some trace elements that can strengthen the properties of steel.

But... Even in a world as big as the previous life, there is only one place on the whole earth to produce a small amount of Uzi steel. It has been excavated and disappeared in hundreds of years.

The world also has this kind of steel.

Even better than that.

For example, Xiao Yun's double knives on his wrist at this time.

If you put it in your previous life, no matter how much it costs, Xiao Yun will try his best to get it! This is already a treasure level thing. It is a treasure in which world and civilization!

But... Too few.

Circulation is impossible.

What can really circulate is only the most common raw materials and the technology that is most easily copied.
