I, the King is a killer

Steel?

How expensive that thing is!

Want to use it on buildings?

That's impossible!

Now ordinary people, even if they want to use a set of metal tableware and kitchenware, are particularly hard.

Not to mention building houses with steel.

Everyone looked at Xiao Yun strangely at this time.

Xiao Yun curled his lips and muttered, "it's strange to see less."

He took a deep breath and said, "you should master the drawing as much as possible. As for the use of steel and main building materials, I have made the workshop ready. The first thing to do is to build the wall for me! "

"Wall?!"

A group of people were surprised again.

Then go to see the drawing immediately.

Sure enough, in a drawing, it did draw an existence similar to the city wall.

Surrounded the whole South City.

"This..."

A craftsman couldn't help but say, "young master, is this to build a city in the city?"

Xiao Yun stretched out a finger and shook it.

Then he said: "first of all, you should understand that the first requirement of the Nancheng I want to rebuild is safety, and the basis of safety is that outsiders can't go in and out at will. In fact, this is the same as the structure of the market, but the partition of the market is not so clear, and there is no feeling of such a high wall, but you should also know that the largest and best houses in the capital, In fact, there are high walls on the outside, but everyone has ignored it. "

When people think about it, it's the same reason.

They all nodded.

Just feel a little wrong in my heart.

Is such a city in the city really right? Really, right?

I always feel like there's something wrong.

Han Sui couldn't help asking, "what has been doing in the workshop, childe, but can that thing really be used as building materials?"

Xiao Yun laughed and said, "then please don't go with Ben. Go to the workshop and have a look. When you see something, you'll judge it."

Xiao Yun led the way, and a group of people followed.

In the carriage, naturally, he was calm and did not feel cold.

It was hard for the craftsmen who followed.

Rub your hands one by one.

When they came, they were paid a high salary. They were all in cars, but now Xiao Yun is in a car, they can't sit and can only follow behind.

That's the rule.

When he arrived at the workshop, Xiao Yun was naturally unimpeded. At that time, the craftsmen behind him, one by one, were almost stripped of the inner and outer floors.

It embarrassed them all.

Of course, some don't quite understand.

They are also the main craftsmen in the workshop.

There are also some secrets of the Xiao family.

On weekdays, you only have to guard against others. Today, it's your turn. It's really hard.

But when they enter the workshop, they will understand.

Why do you get so checked.

A wide field.

Several blast furnaces.

Some soil is stuffed into the blast furnace, then burned into white ash, taken out and placed in a huge mold on the ground.

Stir with water and sand.

Stir into paste.

Then put a few finger thick metal strips in the middle.

Then put it there and wait for it to cool down.

A lot of huge stone slabs produced by this mold have been placed next to it.

Several craftsmen came together.

Knock on the slate.

Reached out and touched it carefully.

Then there was a look of shock.

"Childe, this is... What material is this?!"

Xiao Yun smiled gently.

No direct explanation.

This is not cement!

Although it can be regarded as cement in terms of its use method.

After all, the origin of this name is water-soluble mud, which is different from traditional firebrick.

As for the production method, it is not so complicated.

Cumbersome is a little cumbersome, but it can be done by others. As long as Xiao Yun puts forward his ideas, his craftsmen can always find the right materials and the right ratio, and then make the action.

Day and night, they hardly rest until they get out.

He is the most competent craftsman.

Xiao Yun's method, that's the earth method.

The first is to find lime.

There are many kinds of lime in the world.

Which one is easier to use? Xiao Yun naturally doesn't know.

He could not distinguish the internal components and could not judge which was calcium oxide and which was silicate.

Try anyway.

All kinds of soil, all kinds of stones to burn.

It's always the most suitable one. As for its principle, Xiao Yun doesn't have to consider it.

Like Shennong tasting all kinds of grass.

Which kind of medicine treats which kind of disease, naturally I can't understand whether it contains polyacetic acid or sodium hydroxide. Anyway, it's just a test!

If you try more, the accuracy is higher.

Then there is volcanic mud, or volcanic ash.

The internal structure of this kind of thing is extremely complex. It can even be said that most of the elements can be found in lava.

As for this kind of thing, it's relatively easy to find.

After all, before the earthquake in the north and the dangerous situation in Chunwei, Xiao Yun knew that there must be places where the earth's crust is easy to change. Where there are many earthquakes, the volcano is not far away.

There is an extinct volcano about 300 miles northeast of the capital of the state of Qin.

All kinds of soil and stones around are volcanic rocks formed by volcanic mud in a long time.

Just bring it.

Lime burning, volcanic rock grinding, and then as long as it is stirred with water, it will become a natural binder.

Yes, this thing is actually an adhesive, not its own hardness.

Hard, mostly provided by the middle sand.

Not to mention sand.

Use river sand.

Unlike the rock weathered sand, the river sand is left by the scouring of rivers for thousands of years, which are the hardest essence of stone.

Finding diamonds from them is nothing new.

Plus an iron bar in the middle.

This has become the simple configuration in the simple configuration - reinforced concrete!

of course.

The materials of this world are great.

This thing is simple.

But the performance is not weak!

Solid, natural materials.

He looked frightened at the things he got out.

And this ratio can also be used as filling material.

Can achieve the best sealing effect.

In other words, it can also be used when building.

But on the other hand.

This is a sweatshop.

Without any protection.

When lime is burned, it will form a lot of dust.

This kind of thing enters the lungs and is difficult to be excreted by the body.

So Xiao Yun made a rule here.

The money is very high.

But not for long.

You can't plead.

If you work for a few days, you have to change people.

Then there is a long rest.

Wait a while before you come and work for a while.

Therefore, among craftsmen, it is also called "golden ash fire".

Everyone envies those who can work here.

Even though Xiao Yun has said the harm of this kind of thing.

But I can't hold these guys. They don't accept money or life!

In short, this thing is made.

And do it in batches.

Very fast.

As those craftsmen become skilled, their speed is faster.

Actually, I think so.

It took only a few months from Xiao Yun's idea to the fact that this kind of thing was really made, put into production and expanded its scale.

This is the task he left before he left the capital.

This is the fundamental reason why he wants to buy Nancheng.

It is also the main reason why he doesn't want to promote firebrick.

Compared with firebrick, this kind of thing pollutes the environment much less.

I'm introducing the use of these things to those craftsmen.

Next to him, a craftsman came running with a jar of crooked melons and cracked dates.

"Childe, childe, you see, we burned this when we burned sand!"

Xiao Yun didn't care at all. He took it up and looked at it.

Then the whole person is a little bad.

The corners of the eyes twitched violently.

"Is there any danger when burning this?" asked the trembling voice

"How do you know? At that time, the stove blew up and hurt people, but after several experiments, we gradually found out how to do it! "
