With coke, put the coal thing aside, he can't love this rain, if it doesn't work today, there will be tomorrow, anyway, it will be a long time before the coal will start to sell.

At the very least, we must wait until we can buy all the open-pit coal mines that can be bought, and start to promote coal stoves.

It's not bad for a day or two.

"Lao Wu, don't do it, if you get drenched, it's not a problem, let's burn some coke first, it's much more important than coal."

Wu Li was quite reluctant, how could this prince still have an idea for a while, it was not reliable at all.

However, since Li Chengyang said it, Wu Li also knew to do it.

This time, I didn't look for honeycomb coal, and just put the raw coal into the iron box.

It was still Wu Li who was watching, and Li Chengyang was desperately blowing on the side.

Because there was a bit too much this time, Li Chengyang deliberately extended the heating time.

It took more than an hour for Li Chengyang to put down the bellows in his hand.

When I opened the iron box, a pungent smell sprayed out, sour or sour, not smelly, and very unpleasant.

Li Chengyang was even happier, and this coke was right.

This is smoldering to remove all the magazines in the coal, because it is stuffed in the iron box, there is no time to discharge, and it is piled up.

He put a box of coke in the house and waited for him to dry naturally.

Li Chengyang dragged Wu Li to find the blast furnace for ironmaking.

Nowadays, the furnace is not called a blast furnace, but a shaft furnace, but it is almost the same, there are furnaces on the left and right, and the function is the same.

Naturally, there will be no large shaft furnaces in the Ministry of Industry, but there are many small ones.

The blacksmiths here sometimes use their own secret recipes to make iron, disdainful of the mass goods.

So Wu Li also built a small shaft furnace for everyone.

The small one is good, and the big one doesn't necessarily need much coke, just for more than an hour, Li Chengyang is tired enough, and he can lie down after a furnace.

Let's try the small ones first.

After going around the work department, they chose the best looking shaft furnace, and the two of them decided on their goal, and then went back to the house to move the coke out.

Put a little ignite under the shaft furnace, and then mix the coke, iron ore, and limestone and throw it in.

Finally, Li Chengyang still remembers something, there are not many materials for blast furnace ironmaking, just a few.

Put everything in place, and light the fire from under the shaft furnace.

And then there's the old-fashioned, desperate blowing.

Time passed slowly, and Li Chengyang and Wu Li were silent.

If it can really succeed now, then Datang will definitely usher in a leap forward.

Originally, Wu Li's iron-making method was to directly burn the iron ore with charcoal, because the temperature produced by the charcoal was relatively low.

Then they will get pieces of rotten iron, which are pieces of iron that contain a lot of magazines.

Nowadays people call it sponge iron, which cannot be called iron yet, at most it is the residue of iron.

Then, after repeated tempering, this can obtain a piece of pig iron.

And the temperature of the coke is high enough, plus the half of the blast furnace that Li Chengyang pieced together, you can directly get pig iron when it comes out.

If they succeed in this experiment, then Datang will fully usher in the Iron Age.

If the soldiers of the Tang Dynasty replace all the armor with iron plates on their current leather armor with iron armor.

So for now, no country is an opponent of Datang.

Just push it all the way through.

As time passed, a drop of molten iron flowed out of the shaft furnace and fell to the ground with a clatter.

"It's coming out, it's really molten iron, haha", Wu Li jumped up, and then cautiously lay down, carefully observing the drop of molten iron on the ground.

Li Chengyang saw that he was really successful, and the movements in his hands became more intense.

The drop of molten iron was pulled out by Wu Lipao and left the fire, and the drop of molten iron had quickly condensed into a small piece of iron.

Wu Li took him to his eyes with his clothes, and Bai Sensen's iron piece seemed to have become a peerless beauty in his eyes.

The hourglass iron smelting used by Li Chengyang before was not on the right track after all, and even if it could be practiced iron, it was not enough to attract Wu Li's attention.

After all, the best iron ore, the best equipment, and the best fuel, all of which are limited, and in the end, a little bit of iron is produced, which cannot be mass-produced at all.

But this time it's different, everything is readily available.

The coke can be smoldered for a while, and no matter what the quality of the iron ore is, just stuff it into the furnace, and just find a shaft furnace to train the iron out.

It can be produced on a large scale and in large quantities without any hindrance.

Carefully put the iron piece into the bag, and later make it into an heirloom, the first drop of molten iron in the world that was directly refined, which was his Wu Li's.

Turning his head to look at the shaft furnace, he didn't realize that a lot of molten iron was dripping from it.

Wu Li took out another tool, pried out a piece of iron that had been cooled, and held the iron block alive and dead.

The world's first piece of refined iron is also his, and I am excited to think about it.

It wasn't until Li Chengyang was tired of becoming a dog that the stove finally stopped dripping.

took out the remaining piece of iron and said to Wu Linunu:

"Let's go, what are you doing in a daze, follow me into the palace."

Needless to say, I know how important this thing is, if this thing is done by himself with his head stuffed like before, Li Shimin can eat him alive.

Wu Li also reacted that this matter should indeed be reported immediately.

After throwing out the tenth piece of refined iron in the world from his bosom, he moved.

Well, it's a little heavier, but it doesn't affect the activity too much, so he waved his hand at Li Chengyang:

"What His Highness said is extreme, let's set off."

Li Chengyang looked at Wu Li's huge belly dumbfounded, he had been facing away from Wu Li when he was blowing before, and he didn't pay attention to what Wu Li had done.

"I say, how did so much iron ore come out of such a thing."

I thought it was because of the blast furnace, but it turned out that this Wu Li had already put the previous practice in his arms.

Wu Li's face turned red, and he still said to himself: "How can I say that I also did a favor, why can't I divide something."

Li Chengyang glanced at him teasingly, turned his head and walked out.

The significance of this iron is indeed very great, and if you handle it simply, it is an heirloom, the first thing in the world, and I don't know how much it will sell for in the previous life.

The two of them went out of the door with their front and back feet and went straight to Li Shimin's study.

"Sons (ministers) see father emperor (majesty)".

In front of outsiders, Li Chengyang seems to be much more reserved, and his words and deeds are very disciplined.

"What are you two doing here? Are your iron cylinders made? Li Shimin looked at the two of them with interest.

Li Chengyang and Wu Li glanced at each other, their eyes full of helplessness.

I thought they were keeping it secret enough, but I didn't expect to be inquired about by Li Shimin.

"Let's not talk about that, father, come, show you a big baby", Li Chengyang shook his head, he was used to it.

Isn't it just surveillance, Drizzle, as long as he doesn't have any bad intentions towards Li Shimin, he doesn't believe that Li Shimin will move him for no reason.

Li Shimin let out an "oh" and stood up from behind his desk.

In the eyes of Li Chengyang in the past, nothing was a good thing, even if he Li Shimin's night pearl was only evaluated by Erer.

How high this kid's vision is, Li Shimin has a deep understanding.

Now that he has said that he is a good baby, it is impossible for Li Shimin not to pay attention to it.

"Tell me, what kind of baby is a good baby?" , Coming to the two, Li Shimin asked.

Li Chengyang touched the iron in his sleeve and shook his head, this piece is too small to have any eye-shocking effect.

One hand reached into Wu Li's clothes, fumbled for it, and picked the fastest one to take out.

Wu Li was stunned, this prince was so shameless, he stretched his hand into other people's clothes.

Li Chengyang handed this strange-looking piece of iron to Li Shimin: "This is a big baby."

Li Shimin took the piece of iron, his hand sank, turned upside down, and there was a look of seven or eight catties, and studied it carefully:

"Isn't this just a fast rail, what kind of treasure is it? Didn't you trick me, my skin is itchy again? ”。

I thought it was really a baby, but I didn't expect it to be such a piece of iron, and Li Shimin was quite disappointed.

Wu Li looked at the iron block in Li Shimin's hand on the side, and the corners of his eyes twitched.

There are two scratches on that piece of iron, what kind of iron is that, it is the second piece of fine iron in the world, if you don't want it, give it back to me, I want it.

Li Chengyang smiled: "It's right to be a fast iron block, but what if I tell you that this is what Wu Shilang and I just practiced directly from iron ore?" ”。

Li Chengyang's face was full of pride.

Li Shimin looked at the iron in his hand carefully, and was a little incredulous:

"You said you practiced it directly?".

He understood what Li Chengyang meant, if so, it was really a good baby.

Li Chengyang nodded, with a look of expectation.

"Let's go, take me to see, Xuanjia Army, Duan Zhixuan, come here, ask some people to go with me", Li Shimin immediately came to the spirit, beckoned people and walked outside the palace.

Under Li Shimin's repeated urging, the group soon came to the Ministry of Industry.

As soon as he entered the door, Li Shimin gave Duan Zhixuan a color, Duan Zhixuan nodded, and waved at the Xuanjia Army behind him:

"Fence me all up, and let no one go in or out."

Li Shimin called Wu Li over: "Lead the way, let me see what kind of thing can have such a miraculous effect."

When he arrived in front of the previous shaft furnace, Wu Li briefly introduced it, and Li Shimin looked around the shaft furnace.

"What's the difference? Isn't it just a plopping shaft furnace, prince, how do you do it, make it for me again", Li Shimin is no stranger to ironmaking, and there is nothing strange about the shaft furnace in front of him, how can it have such a miraculous effect.

"Father, this will take a long time", practice again? That might be late at night.

"It's okay, this kind of thing has to be seen in person to rest assured", Li Shimin waved his hand to show that he didn't mind, and sat down casually after finding a place.

Looks like I'm really going to spend it on this today.

There was no way, Li Chengyang and Wu Li restored the previous steps again.

Burn the coke, pull the bellows, burn the blast furnace, pull the bellows.

It was only when I tossed until the time of the child that I finally finished practicing a furnace of iron.

When the first drop of molten iron flowed down, Li Shimin changed his usual calmness and lay directly in front of the shaft furnace, carefully watching the molten iron slowly drip down.

It wasn't until there was no more movement in the shaft furnace that he stood up:

"Except for the two of you, but the rest of the people know about it?"

"No", Li Chengyang scratched his head: "Father, you also know that I have a strong sense of secrecy."

Li Shimin nodded, turned his head and instructed Duan Zhixuan behind him: "Bring everything back to me, and no trace can be left here."

Duan Zhixuan nodded, and began to beckon the Xuanjia Army to move everything away.

In order to thoroughly carry out Li Shimin's orders, even the stone bricks and soil on the ground did not escape the fate of being taken away.

Wu Li was also taken away at the same time with the stone bricks, and he originally wanted to take Li Chengyang away, but Li Chengyang glared back.

"Go back by yourself!" Phew, I don't have any face.
