The so-called steel filling method is to use two kinds of iron with different carbon content to fuse. Wrought iron with low carbon content is placed in the furnace first, and pig iron with high carbon content is placed on the mouth of the furnace.

As the furnace temperature rises, the pig iron will begin to melt into molten pig iron. At this time, it is necessary to constantly stir the wrought iron in the furnace so that the molten pig iron is evenly poured on it.

In this way, the carbon in the pig iron will penetrate into the wrought iron, and the carbon content of the wrought iron will slowly increase, turning it into steel.

Pig iron, which has a reduced carbon content, will slowly turn into steel. In this way, the speed of obtaining steel is greatly accelerated, and if you want to obtain steel with different carbon content, you only need to adjust the ratio of pig iron and wrought iron.

However, Qin Ze only knew a rough idea, and how much proportion should be used, which Qin Ze didn't understand.

But Qin Ze also knew that for those masters, it was enough to test them a few more times.

Soon the master of the Ordnance Supervisor was called to the Lizheng Hall, a lean man, tall and tall, with his bare skin and a little shiny. Especially when Qin Ze noticed the other party's hand, his knuckles were protruding outward. At first glance, he is a master blacksmith who has been working all year round.

As soon as the other party came up, he saluted Li Er and the adults, but directly ignored Qin Ze on the side.

This is to blame, as a master craftsman, people are also six products in the register. Although he doesn't have any real power, he is much stronger than Qin Ze, a nine-rank product.

The master's surname is Wu, and it was only through Li Er's name that Qin Ze understood. Otherwise, people wouldn't even tell Qin Ze his name.

"Master Wu, you have been in charge of weapons for several years, have you ever heard of the steel filling method?" Li Er was the first to speak, and asked Master Wu about the steel filling method in Qin Ze's mouth.

The Tang Dynasty was a country established by overthrowing the Sui Dynasty, and in many ways it still used the personnel of the Sui Dynasty. And this master craftsman Wu has been a master craftsman of the Ordnance Supervision since the Sui Dynasty, and he has been in charge of the production of this weapon for six years.

But he really had never heard of this steel filling method. At the moment, he shook his head and said: "Weichen has been making weapons for so long, and he has only heard of the steelmaking and frying methods, and I really don't know what this steel-filling method is. ”

Hearing this, Li Er also nodded, and said to Qin Ze, who was waiting on the side: "You can tell me about the steel filling method in your mouth." ”

At this time, Master Wu noticed Qin Ze on the side, he subconsciously looked at Qin Ze's hands, but found that those hands were white and pure, where did they look like the hands of an iron striker.

Looking up at the other party's weak body again, I was even more suspicious that what kind of steel filling method was just nonsense.

Qin Ze also saw the disdain in the other party's eyes, and scolded short-sightedness in his heart, but he said the steel filling method again.

At first, Wu Dajiang was still an expressionless dead face, but when he heard that pig iron and wrought iron were going to be mixed together, his eyes lit up.

The layman looks at the bustle, and the insider looks at the doorway.

Although he only listened to Qin Ze's words, this method of using iron with different carbon content to fuse it also made him suddenly brighten.

On the other hand, Wei Chigong was in a daze, and he didn't know what Qin Ze was talking about. However, he waited until he finished speaking before he rushed forward and asked Master Wu, "How is it?" Is this kid's method? ”

When Wei Chigong said this, his eyes were looking at Cheng Lao You, and the meaning was very clear. As long as Wu Dajiang said a word, he would humiliate Cheng Laoyou.

Results......

Wu Dajiang didn't seem to hear it, his two hands kept gesturing in the air, and he was muttering about some pig iron and wrought iron in his mouth, as if he had been stunned.

"Well, isn't this Master Wu crazy?" It was Cheng Lao Demon who spoke, and he was also a little curious when he looked at Master Wu's behavior.

"Wonderful, wonderful." Just when Cheng Laoyou and Yu Chigong wanted to wake up Master Wu, this guy suddenly shouted.

Then he grabbed Qin Ze's hand and asked as if he had fallen into an evil spirit, "Where did you learn about this method of steelmaking?" But where did the teacher come from? ”

"Uh~"

Qin Ze looked at the other party helplessly, and really didn't know how to answer. I could only scratch my head and say: "I was injured in the brain before, and I can't remember these things clearly, but I don't know if this method can be used?" ”

Hearing Qin Ze say this, Master Wu was also annoyed. I was so disappointed that I couldn't meet a master who could come up with such a method.

Wei Chigong on the other side couldn't stand it anymore, and asked with a big grin at Master Wu: "What do you say about this method?" ”

His words also reminded Master Wu to pay attention to the current situation, but His Majesty Li Er was standing aside, and he couldn't tolerate such rudeness.

Master Wu hurriedly let go of Qin Ze's hand, and was about to confess to Li Er, but was directly interrupted by the other party: "I just want to know if this method is useful?" ”

"Although Your Majesty Hui has not experimented yet, judging from Weichen's experience, this method is absolutely useful."

It can make Wu Dajiang gamble on his reputation, which is enough to show the ingenuity of this steel filling method.

Li Er was also in a good mood when he heard this, and asked again: "Master Wu thinks that if this method is used, how far can my Datang's steel go?" ”

This is where Li Er cares, if there is enough steel. The strength of the army will definitely increase several times, and when the time comes, each person will make a pair of steel armor, what are you afraid of Turkic?

"Back to Your Majesty, it can be at least ten times more than what Weichen has seen." Master Wu was also ecstatic, as a master craftsman of the Ordnance Supervisor, he didn't want to have endless steel for himself.

The words came out of Master Wu's mouth, but they were much stronger than Qin Ze. At this time, even Wei Chigong frowned, standing aside without saying a word.

"Okay, okay." Li Erlian said two good words.

Du Ruhui on the side also walked out from the side, and took the opportunity to congratulate Li Ershi: "Congratulations for Your Majesty for this good plan, and congratulations for my Tang Dynasty soldiers." ”

This sycophant was patted, and even Qin Ze on the side couldn't help but want to give a thumbs up.

Li Er was also excited, and when he turned his head, he was about to reward Qin Ze, but he suddenly found that this kid was also looking forward to it.

Immediately Li Er calmed down, this kid's identity is unknown now, and he doesn't know his origin, so he really doesn't feel at ease to reuse.

So Qin Ze, who was waiting for Li Er's reward on the side, saw Li Er's head tilted to the side again, as if he didn't see himself.

"I'll go, it's for nothing, so why don't you reward a few copper coins?" Qin Ze felt that he wanted to cry without tears.

"In that case, I can't say anything more, so I'll allow you to go to the Ordnance Supervisor to make a few weapons." After speaking, he waved his hand and signaled that Qin Ze could go down.

"I didn't ...... Gone! ”

There was a twitch on Qin Ze's face, but there was nothing he could do about it. If he couldn't see what Li Er meant, he would have lived in vain for decades.

So Qin Ze withdrew from the Lizheng Hall empty-handed, but fortunately, his goal of making weapons was achieved, and it could be regarded as a gain.

And just after Qin Ze left, the few people in the Lizheng Hall couldn't hold it back anymore. All of them had ecstasy on their faces.

Li Er waved his hand, instructed Master Wu a few words, and asked him to retreat as well.

When there were only four of them in the hall, ecstasy turned to laughter.

Ten times the amount of steel, what is the concept, it can completely increase the military strength of Datang several times. This is not a good thing for Li Er. For the Tang Dynasty, which has always been invaded by the Turks, it is not a good thing.

"Your Majesty, I don't know who Qin Ze is? Why have you never heard of it? Du Ruhui was the first to speak, but he asked about Qin Ze's origin.

Li Er also shook his head and looked at Cheng Laoyou, this person still knew because of Cheng Laoyou. He also sent someone to check these days, but he didn't have a clue at all.

Qin Ze has a wooden plaque on his body that records his identity, and it is written as a person from Chengji, Longxi. Li Er also asked people to go to Jingzhao Mansion to inspect, but there was no record of this person at all.

It was as if he had fallen from the sky, and Li Er even doubted whether Qin Ze was a disciple of an immortal family who had been sent to the worldly world to practice. Otherwise, why would you act so strangely and yet come up with such a wonderful method?

Cheng Lao Demon also shrugged when he saw Li Er looking at him, and said: "A month ago, Xiao'er was looking for him in Chang'an, and he was taken in because he was pitiful, who knew that this kid was so weird. ”

"So even Your Majesty doesn't know the origin of this son?" Du Ruhui frowned, but his heart became more and more curious.

"Regarding his origin, I will check it slowly in the future. In short, he is still bent on Datang, as long as he doesn't suppress him too much, he won't do anything wrong. ”

Li Er's words are reasonable, as long as Qin Ze is facing himself and the Tang Dynasty for a day, he will not move him. After all, he surprises himself from time to time.

"I just can't give him a good face, this kid is a guy who climbs along the pole."

At the end, Li Er added another sentence in his heart.

Cheng Laoyou on the side smiled the most proudly, especially when he saw Wei Chigong on the side, his mood was even better.

"Old man Wei Chi, you remember your words, this time this kid made something, you right Wuwei can't touch it."

As the general of Zuo Wuwei, Cheng Laoyou, since he was trapped in Chang'an, joking with Wei Chigong and making small conflicts is also an activity on weekdays.

Although it seems that the two people are not convinced by each other, the other party knows in their hearts that they are grasshoppers tied to a rope. So the relationship is still very good in private.

"Isn't it just eating locusts in front of Zuo Wuwei? I hadn't eaten anything back then, and I was afraid it wouldn't work. Wei Chigong raised his chest, and said that it was an obligation.

"You ......"

Cheng Laoyou pointed at Yu Chigong and didn't say anything for a long time.

The two mixed river fish have thick skins. There are no scruples in doing things.

Of course, Qin Ze didn't know this, he had been worried about offending Wei Chigong since he left the Lizheng Palace.

This has just solved the problem of the basin, and I have added another hoop to myself, what have I done?

As for whether Wei Chigong would trouble Qin Ze, he was originally disdainful of his identity, and he was also mistaken for Qin Ze's arrogance when he was angry before. Now that I understand everything, the anger will naturally subside.

However, after looking at the happy expressions of Cheng Laodemon and Li Er, he suddenly felt that bullying and bullying Qin Ze seemed to be a good choice.
