Martial: I Started The Technological Revolution In Ancient Times

He combined the mud and water into a state of moderate hardness.    

Then he kneaded it into a small stove to fill his stomach.    

It was very much like an inverted funnel.    

Then, he kneaded it carefully and made it almost as thick as a whole, leaving a hole up and down.    

Then, he ran to the hole, squatted there, and stretched out his hands to grab the ground.    

His fingers looked slender and fair, but when placed on the ground, they looked like rakes, small branches, pebbles, and some gravel the size of beans.    

To be more precise, it should be soil powder.    

Xiao Yun grabbed and rubbed them continuously.    

He separated the branches and stones, leaving only a pile of black sand.    

He gathered them and placed them in the small stove.    

Then, he placed all kinds of flammable branches and some dry grass on the stove. Then, he placed large pieces of wood on the stove.    

When everything was ready, Xiao Yun was not in a hurry to light the fire.    

Instead, he used wood to make a "drum."    

He used the leather to block the template, leaving two handles behind. As they opened and closed, strong wind blew out from the bag.    

Xiao Yun nodded and lit the fire.    

First, he slowly used the leather drum to blow, then he increased the speed, causing the wind to blow fiercely.    

He saw that the small stove was instantly burnt until white smoke rose up.    

The stove itself was emitting something similar to water vapor, while the stove's opening was emitting white smoke of plants and vegetation.    

Yes.    

White smoke.    

Not black smoke.    

What did Xiao Yun really want?    

It wasn't the light from the burning plants.    

It was the black smoke that appeared after the plants were burnt!    

Due to the problem with the furnace's structure, the black smoke would be left behind for a short period of time.    

Then, by blowing the air and increasing the amount of oxygen in the furnace, the black smoke would instantly become a new fuel!    

Furthermore, the temperature that it would burn out would be much more ferocious than that of plants and vegetation!    

This was "knowledge."    

This method was extremely simple, but in ancient times, it had been over a thousand years before it was discovered. It was only until a hundred years ago when Xiao Yun was still in that era that people finally understood the reasoning behind it.    

They understood what kind of high temperature some substances would produce after being fully burned.    

Even the "furnace explosion" that happened often in ancient times was actually because the ventilation was too good. Some sort of cyclone was formed inside the furnace, and the cyclone sucked oxygen into it. It caused the temperature of the furnace to rise rapidly, causing the furnace to be unable to withstand the heavy burden of the temperature. In the end, it exploded.    

It was a very dangerous thing.    

Want to solve it?    

Actually, it was very simple.    

As long as the overall structure of the furnace was slightly altered, it would be fine.    

And this small change was only achieved after nearly a thousand years in ancient times.    

After all, if knowledge mostly came from experience, then leveling up would be very difficult.    

And Xiao Yun knew the principle behind it.    

It was a level higher.    

When one's knowledge was higher, one could achieve the same goal by using a relatively simple method.    

The more the furnace burned, the sturdier it became.    

The temperature inside the furnace was also getting higher and higher.    

This process continued for about an hour. Xiao Yun added more than ten times of dried wood before finally stopping.    

He wiped his sweat and looked at the small furnace with a face full of joy.    

Wait! The temperature inside gradually dissipated. He used the wooden stick to pull out a black irregular object from the roots of the grass and wood ashes.    

It was like a black poached egg.    

He took it out and poured some water on it...    

A sizzling sound could be heard without an end.    

However, it quickly disappeared.    

Steam and white smoke were rising from it.    

This caused the two women to open their eyes wide at the same time, their faces filled with disbelief.    

This... This was clearly metal!    

Xiao Yun tried touching it, and then he held the metal in his hand and knocked it twice on the stone. Clang! Clang!    

He then rubbed it a few more times on the stone, and a metallic lustre immediately appeared on it.    

Xiao Yun was overjoyed.    

He changed to another rock wall and rubbed it crazily.    

He changed a few places in the cave.    

He ground each place for a period of time.    

Wait. After the grinding, he threw it in front of Tuoba Tian'er and said with a face full of arrogance, "What did you say just now?"    

Tuoba Tian'er picked up the metal.    

There was actually a blade on it!    

Smelling it, it was the smell of raw iron.    

Using the edge of the edge, he scraped off a piece of bark from the tree branch. The cut was quite smooth.    

She was a little stunned.    

She held up the pancake and said, "What... What's going on? How can forging iron... be so easy? "    

Iron.    

It was something every country in this world lacked.    

Even the rich like Sun Moon Country did not mean that every civilian family had a complete metal weapon.    

A kitchen knife might be.    

But a hoe, a shovel, and so on, that might not be the case.    

It was even harder to count on plowing.    

However, this was still much better than other countries.    

After all, even Xiao Yun had seen some civilians use wood to make kitchen knives!    

As for whether it was good to grind wood as a kitchen knife or not? To modern people, it was definitely not good to use, but to the people of Qin Country, it was still okay. At least it could be used.    

Why?    

Because the people of Qin Country could not eat meat every year!    

If it was cutting vegetables, the wooden knife could actually do it.    

It lacked iron.    

Salt iron and the like were indeed not lacking. It seemed like the Xiao family was the only place that existed in the world.    

And now, Xiao Yun had used such a simple thing to get the iron out in front of them in an instant? !    

Could such a thing be so simple?    

How did they, the North Wei, refine iron? That was quite troublesome.    

Even if it was the entire continent, the North Wei was still a large iron smelting country.    

Because they had a lot of iron ore!    

If one wanted to forge iron, the first thing to do was to have enough iron ore.    

Iron ore itself was a very evil place, and a strange thing often happened. Mining itself was risking one's life.    

After the iron ore was mined, they used the horse carriage to travel a long distance to the big town and handed it over to a specialized iron workshop.    

The workshop had to perform the ceremony of offering sacrifices to the three animals and opening the furnace.    

The master would personally arrange the raw materials and adjust the furnishings in the furnace. Then, he would have to rush to the right weather to start the iron smelting!    

This was a huge risk.    

The probability of the furnace exploding was about 30%.    

And once a furnace exploded, it often meant casualties.    

So this is also a very risky thing.    

Even if these are all done, the refined iron might not be able to be used.    

Some of the refined iron would not be able to be used to produce all kinds of tools. If one picked up a piece, even if one used their hands to break it, that thing would also be broken like a piece of earth!    

Refining iron was too difficult!    

What was the result?    

In front of her, Xiao Yun used something so simple that it could not be any simpler, and he actually refined iron? He didn't even use iron ore.    

Wasn't this a bit too much?    

Could this fellow really be an Immortal's disciple?    

She even wanted to knock Xiao Yun's head open right now.    

She wanted to see if there was a small white-bearded Immortal hiding inside.    

What Xiao Yun wanted to do wasn't over yet.    

He got some more black soil.    

This black soil was different from the black soil from before.    

Some black powder would automatically gather together, as if there was something sticky in the middle that stuck them together.    

Xiao Yun was overjoyed.    

He hurriedly took advantage of the fact that the furnace's temperature had not completely dropped and started another furnace.    

This furnace was different again.    

Because Xiao Yun had dug out a hole at the bottom of the furnace with sand and stone. It was in the shape of a nail.    

He then started the furnace again.    

Wait. After the metal was taken out, it actually had the shape of a nail.    

It was just that this nail was very big.    

It was thicker than a thumb and was half a foot long.    

After another round of grinding, it finally became a big shiny nail.    

However, its speed of melting was really fast.    

A layer of black rust soon appeared on it.    

Black rust was always better than yellow rust.    

One. Which means isolating the oxygen layer, one means rotting.    

Xiao Yun knocked the nail on the stone wall a few times and listened carefully.    

In the end, he sighed and threw the nail to the side as if he was throwing garbage.    

"Sigh, there are too many sand eyes. They are useless."    

Tuoba Tian'er hurriedly picked up the nail and carefully examined it. Then, she stared at Xiao Yun with a face full of resentment.    

This was not good enough?    

This was already much better than the things produced by the ordinary forging workshop in the North Wei.    

In the end, in Xiao Yun's eyes, it became too many sand eyes?    

Looking at the small, joke-like smelting furnace again, Tuoba Tian'er's expression became even more bitter.    

She even muttered softly, "Looks like capturing you is right. If you are allowed to help Qin Country continue to develop, in less than 20 years, the Northern Wei will be gone."    

Leng Yueling bit her lips and suddenly said from the side, "What you can do has already been done and done very well. Now that you are the Literary Sect's saintess of the Northern Wei, you are already dead. You are not going to let yourself go just because of you?"
