Only then can we resist the peeps of Li Zicheng and Zhang Xianzhong and the invasion of the alien Jurchen Qing army in the north.

"I don't want you to be able to make the steel you want to make, but you want to make me cast iron that is hard and very brittle."

Li Yue smiled indifferently and said coldly.

Hearing the word cast iron, Tang Yonggang was stunned for a moment.

Cast iron is too simple, it is just scrap steel that has not been successful in refining tank steel.

"Young master, if you want cast iron, it's very simple, and now there are more than 100,000 catties of cast iron in the workshop."

Tang Yonggang said excitedly.

Hearing this, Li Yue couldn't help but smile bitterly and shook his head.

"I want a kind of white cast iron that is brittle and hard, and the bearing capacity is not strong, this kind of cylinder should be easy to refine, and I will give you a mold, directly into the mold."

Li Yue said very seriously.

Hearing this, Tang Yonggang immediately became excited, knowing what Li Yue was talking about.

Moreover, there are many so-called white cast iron, which are almost all scrap materials and have no effect.

"Young Master, don't worry, I will give you as much as you want now, this refining technique is very simple."

Tang Yonggang said excitedly.

"Okay, I'll draw a model for you now, you find someone to make it, and after the production is completed, you must divide the work day and night to make it, I want a very large amount."

Li Yue was also a little excited, and after finishing speaking, he directly raised his feet and entered the room.

When he found pen and ink, he began to draw the warhead of a grenade with his own imagination.

"Since I can't make steel-filled steel that can make firearms, I'll take this convenient and durable good thing first."

Li Yue sighed secretly in his heart while drawing the picture.

After a while, the drawings were finished, and Tang Yonggang immediately asked a craftsman to make a model according to the drawings.

It's just that today's craftsmen do not make models with machine tools, but by hand.

At the same time, Li Yue sent someone to find a carpenter and began to make the wooden handle of the grenade.

The craftsman who made the mold and the carpenter who made the handle were called together.

Li Yue looked calm at this time, looking at the two top craftsmen, and didn't know how to explain his thoughts.

When they saw the two of them holding their drawings and looking at them carefully, they both frowned.

When he didn't know how to start, Li Yue suddenly remembered the porcelain thunder he had created.

"Come on, any of you still have porcelain thunder in your hands, bring me two."

Li Yue looked urgent and shouted loudly.

As his voice reached the outside, in the blink of an eye, a guard entered, placing the two porcelain rays he was carrying on the table.

"Young master, although this thing is easy to use, it is very dangerous, and if you are not careful, it will explode by itself."

The guard said with a worried expression.

Hearing this, Li Yue was still a little impatient.

The porcelain lei was researched by himself, and it is certain that there is danger, but when someone says this, I feel that my ability is not enough.

"Okay, don't talk about this, you go down first, I'll call you if there's something."

Li Yue said impatiently.

Hearing this, the guards hurriedly withdrew from the room, and only Li Yue, Tang Yonggang and two craftsmen were left in the room.

"You all saw that, right? That's what I wanted, it's not convenient to be portable right now, and it's extremely unstable. ”

Li Yue was very careful and began to introduce the porcelain thunder in front of him.

Hearing this, Tang Yonggang also understood that this thing was extremely dangerous, and he couldn't wait to retreat to the end.

"Young master, do you want us to make this kind of porcelain vase out of white-mouthed broken steel?"

Tang Yonggang asked tentatively.

"You're right, that's what I meant, but this vase isn't made according to the mold pattern I just painted."

Li Yue said with a serious face.

"According to the young master's meaning, I can still forge this kind of cast iron bottle."

The blacksmith said confidently, holding the drawing in his hand.

"I'm not asking you to tell you to forge this mold to forge the iron kettle I described, but to work with him, you know?"

Li Yue was a little angry, it seemed that the blacksmith in front of him had not heard what he had said and began to answer.

The blacksmith who heard this also felt Li Yue's unhappy expression, and immediately lowered his head and acquiesced.

The carpenter, who stood silent, took his drawings and looked at them carefully, as if he wanted to find the mystery.

Li Yue was a little relieved to see this, after all, the other party was really serious.

Otherwise, like the blacksmith next to him, there is not much need.

"How's it going? Do you see the point of the wooden handle I asked you to make? ”

When Li Yue spoke, his helpless expression had already been revealed, and he undoubtedly seemed to be a little disappointed with the two craftsmen in front of him.

"Young master, if my guess is correct, you should want me to make a wooden handle that can be perfectly integrated with the iron bottle."

The carpenter asked tentatively.

Hearing this, Li Yue immediately got up excitedly.

"Okay, you're not a stupid person yet, so I'll let you two work together to put two different things together, and it's easy to disassemble and assemble."

Li Yue looked at the voices of the two with a solemn expression, both with a bit of stress, as if he was paying attention to this matter.

"Young master, I know clearly, I will definitely make what you say, the model will be produced in one day, and ten thousand bottles can be mass-produced in two days."

The blacksmith said very solemnly.

"Okay, just do it, remember, it's detachable and fitted, it's a perfect fit, that's what I requested."

Li Yue was very satisfied, and immediately got up and left, after all, more important things were still waiting for him at this time.

After Li Yue left, the whole workshop began to increase its horsepower, and it seems that the success rate of this kind of cast iron is extremely high.

After all, in their opinion, the so-called white cast iron is nothing more than scrap steel.

It is hard to practice steel, but it is very labor-saving to make scrap steel.

Tang Yonggang was almost at full power, and while refining cast iron, he began to study more tenacious steel filling.

After Li Yue left, he ran all the way to Huai'an City.

It was already dark when I left, and by the time dawn I had already arrived in Huai'an City.

However, Tang Yuan and the others had already left with the army for nearly two days.

Li Yue, who had been on the road all the way overnight, returned to Huai'an City and ran directly to Li's Mansion.

Li Yue, who had a frosty face, looked at the old lady Li who he hadn't seen for a long time, and he was also very excited.

Originally, it was already sleepy to travel overnight for two nights and a day, but this moment dissipated.

Especially Mrs. Li, when she saw Li Yue return to the house, her excitement was beyond words, but she pretended to be solemn.

"Grandpa, it's good that you're okay."

Li Yue said excitedly.

"You kid, you're too impatient to do anything, if you can take your time, it will be more secure than now."

Old Lady Li said with a solemn expression.
