Martial: I Started The Technological Revolution In Ancient Times

How expensive was that thing!    

You want to use it on buildings?    

That was simply a fantasy!    

Now, even if they wanted to use a set of metal utensils, it would be extremely difficult.    

Not to mention using steel to build a house.    

Everyone looked at Xiao Yun with a strange expression.    

Xiao Yun curled his lips and muttered, "Don't be ignorant."    

He took a deep breath and said, "You guys try to master this blueprint as much as possible. As for the use of steel... As for the use of the main construction materials, I have already asked the workshop to prepare them. The first thing you need to do is to build the city wall for me! "    

" City wall? "    

The group of people were shocked once again.    

Then, they immediately went to look at the blueprint.    

Sure enough, within the blueprint, there was indeed an existence similar to a city wall.    

It surrounded the entire South City.    

"This..."    

One of the craftsmen couldn't help but ask, "Young Master, are you going to build a city in the city?"    

Xiao Yun stretched out a finger and shook it.    

Then he said, "First of all, you must understand that I want to rebuild the South City. The first requirement is safety, and the foundation of safety. It is that outsiders are not allowed to enter and exit as they wish. In fact, this is the same as the structure of the shop. However, the partitions of the shop were not that clear, nor did they have the feeling of a high wall. However, you should also know that the biggest and best outpost in the capital... In fact, there are high city walls on the outside, but we've all overlooked them."    

Everyone thought about it and agreed.    

They all nodded.    

However, they still felt that something was not right.    

Was this city in the city really correct? Was it really right?    

He kept feeling that there was something wrong with it.    

Han Sui couldn't help but ask, "The workshop has been doing something, Young Master. But can that thing really be used as building material?"    

Xiao Yun laughed and said, "Then I'll have to trouble everyone to follow me to the workshop. When you see the things, you can judge them."    

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

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

It was the craftsmen who had to suffer.    

Each and every one of them rubbed their hands together.    

When they came, they were treated very well. They were all sitting in cars, but now that Xiao Yun was sitting in a car, they could not sit in it anymore. They could only follow behind.    

This was the rule.    

When they arrived at the workshop, Xiao Yun would naturally be unimpeded. At that time, the artisans at the back would be inspected one by one, and they would almost be stripped naked.    

It made them feel a little awkward.    

Of course, they also didn't quite understand.    

Logically speaking, they were the main craftsmen in the workshop.    

They also had some secrets of the Xiao family on them.    

Usually, he was the only one who guarded against others, but today, it was his turn. It was really not a good feeling.    

However, when they entered the workshop, they understood.    

Why did he receive such an inspection?    

It was a very wide area.    

A few blast furnaces.    

Some of the soil was stuffed into the blast furnace and burned into white ash. After being taken out, it was placed in a huge mold on the ground.    

It was mixed with water and sand.    

Stirred into paste.    

He then stuffed a few finger-thick metal strips in the middle.    

Then, he placed them there and waited for the cool down.    

At the side, there were already a lot of huge stone plates made from this mold.    

A few craftsmen moved over.    

They knocked on the stone slabs.    

They reached out and touched it carefully.    

Then, his face was filled with shock.    

"Young Master, what... what material is this? "    

Xiao Yun smiled.    

He did not explain it directly.    

This was not cement!    

Although from the way it was used, it could be considered cement.    

After all, the origin of this name was cement, and it was different from traditional bricks.    

As for the production method, it was not that complicated.    

It was a little complicated, but it could be done by other people. As long as Xiao Yun suggested the idea, the craftsmen like him could always find suitable materials, make suitable proportions, and then make the movements.    

Day and night, before they made it, they almost never rested.    

It could be said that they were the most competent craftsmen.    

Xiao Yun's method was the earth method.    

The first thing he needed to do was to find the lime.    

There were many types of lime in this world.    

Which one was more useful? Xiao Yun naturally did not know.    

He could not differentiate the internal components and could not determine which one was calcium oxide and which one was silica salt.    

He would try anyway.    

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

It was most suitable for burning. As for the theory behind it, Xiao Yun didn't need to think about it.    

It was just like how Shennong tasted all sorts of herbs.    

What kind of medicine could cure which kind of illness? Naturally, he could not figure out whether it contained polyethyric acid or sodium hydrogen oxide. In any case, it was just a test!    

If he tried too many times, the accuracy would be higher.    

Then, it would be volcanic mud or volcanic ash.    

The internal structure of this thing was extremely complicated. It could even be said that most of the elements could be found in lava.    

As for this thing, it was relatively easy to find.    

After all, the previous earthquake in the north and the dangerous situation in spring hunting had let Xiao Yun know that there was definitely a place in the vicinity where the earth's crust changed easily. The location where there were many earthquakes was not far away from the volcano.    

About three hundred miles northeast of the Qin Country Capital, there was a dead volcano.    

All kinds of soil and rocks in the surroundings were volcanic rocks formed from volcanic mud that had existed for a long time.    

He took them directly.    

Lime burned, volcanic rock grinded, and as long as it was mixed with water, it would become a natural adhesive.    

Yes, this thing was actually a adhesive, not that it was hard on its own.    

Hard, most of it was provided by the sand in the middle.    

And there is no need to talk about sand.    

Using river sand.    

Different from the sand that was weathered by rocks, river sand was left behind by thousands of years of washing by the river. It was the hardest essence of the rocks!    

Finding diamond from within was nothing new.    

In addition, there were iron tendons in the middle.    

This became the simplified model in the simplified version - reinforced concrete!    

Of course.    

The materials in this world were too good.    

Although it was a simplified version.    

However, its performance was not weak at all!    

It was a genuine natural material.    

Even he himself was afraid of the things he created.    

And this ratio of materials could also be used as a filling material.    

It can achieve the best sealing effect.    

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

But on the other side.    

This could be considered a blood sweat factory.    

There was no protection.    

When the lime was burnt out, it would form a lot of dust.    

When this thing entered the lungs, it was very hard for the body to excrete it.    

Therefore, Xiao Yun set a rule here.    

The money for example was very high.    

But he couldn't do it for too long.    

He couldn't even plead.    

After working for a few days, he had to change people.    

After that was a long period of rest.    

After a while, he would be able to come over and work for a while.    

Thus, among the craftsmen, this was also known as the "Golden Gray Flame."    

Those who could come here to work were all envious.    

Even though Xiao Yun had already mentioned the danger of such a thing.    

They could not resist the fact that this group of fellows refused to accept their fate even if it was money!    

In short, this thing was made.    

And it was made in bulk.    

It was very fast.    

As the craftsmen became skilled workers, their speed became faster.    

Actually, that was true.    

It only took a few months from the time Xiao Yun proposed the idea to the time when this kind of thing was really produced and put into production to expand the scale.    

This was the task he left behind before he left the capital.    

This was also the main reason why he wanted to buy South City.    

It was also the main reason why he didn't want to promote fire bricks.    

Compared to fire bricks, this kind of thing was much less polluting to the environment.    

He was explaining the usage of these things to the craftsmen.    

A craftsman beside him ran over with a broken jar in his hand.    

"Gongzi, gongzi, you see, when we were burning the sand, we even burned this out!"    

Xiao Yun didn't care about it at first, but he casually picked it up to take a look.    

After that, he felt a little uncomfortable.    

The corners of his eyes twitched violently.    

He asked with a trembling voice, "When the fire is burning at this time... what kind of danger is there?"    

"How does the young master know? The stove was blown up, and someone was injured. However, after a few experiments, we gradually found out how to deal with it! "
