With the emergence of refined steel.

Zhang Feng is also very excited, but now if you want to make fire guns, you think it's a little early. At least, this batch of steel can't be made now.

This thing must be a high-precision seamless steel pipe, otherwise it is easy to cause the danger of blasting, so Zhang Feng dare not be careless. He can only think about it again and again in his heart while trying to find a way.

But Li Shimin couldn't wait. Seeing that Zhang Feng was like this, he hurriedly asked, "Fengzi, how is this thing? Can you use it? Tell me if you can use it?"

"If not..."

Zhang Feng couldn't help staring at the speech and said, "well? Who told you that my refined steel is not working? Let me tell you the truth, I've not only made this thing, but also very, very good, which is much beyond my imagination. However, if this thing wants to be made into what I said, it's still a little hot, at least..."

Zhang Feng's words haven't finished yet, but seeing Li Shimin's anxious face, he hurried to say again: "what's your hurry? What's your hurry? You listen to me."

Zhang Feng was speechless.

On the contrary, Li Shimin didn't care at all at this time. Seeing Zhang Feng looking at him, he said, "can you do this thing? It's really hard for you to lift people's appetite like this. If you put someone else, you'll want to go up and beat people tomorrow morning."

Yu Shinan's people couldn't wait at this time. Seeing this, they hurried forward and stared at the iron in Zhang Feng's hand, with a dignified face.

Although they don't want Zhang Feng to do this thing, after all, in their view, this thing is simply not doing business, but then again.

They are not really stubborn, but they can't see Zhang Feng wasting his energy elsewhere.

For others, these things are really good things, but for Zhang Feng, what is this? This is a waste of time!

Yu Shinan asked eagerly, "Fengzi, can you do this thing? If not, let's focus on our studies."

Li Shimin was a little unhappy for a moment.

What is this saying?

Do you mean that you can do whatever you want with others, but here in Zhang Feng, he just doesn't do his job?

However, it's hard for Li Shimin to say it. He just glanced at Yu Shinan and others with some bad intentions, but Yu Shinan didn't see it. He was still persuading Zhang Feng to focus on his studies. These heresy would only make him waste his studies and so on.

Zhang Feng saw several people talking more and more urgently. He couldn't help interrupting several humanitarians: "I didn't say this thing can't work. Why are you talking more and more urgently? I just have time to do it."

Argynon and others who pestle aside are actually more eager than everyone present, including Li Shimin.

Because this time, although Zhang Feng has promised their gold and future smelting, and even promised that they would send letters to their families, the arrival of their families is particularly important in their hearts.

And there's one more thing. After all, they really don't know whether this thing can work or not.

As craftsmen, what they want most is to make achievements, but now Zhang Feng hangs them with a word.

They did not dare to ask. They could only watch several people quarrel.

Zhang Feng was a little annoyed by the noise. He wanted to pretend to be mysterious. How did this happen? Everyone was suspicious of this thing?

Zhang Feng quickly stopped the crowd: "this thing is very good, but although it is said that he can't make the barrel of a fire gun, if he makes rifling or binding, it's more than enough, and he's heavier..."

Before Zhang Feng finished, Li Shimin quickly interrupted him: "I don't understand and don't want to hear what you said about rifling and framing the barrel. Just say, this thing is OK or not, isn't it?"

"As for such a big bend?"

See.

Yu Shinan and Al Jinnong also showed a confused expression.

Zhang Feng could only shake his head and sigh.

What a shame!

If this is something that even three-year-old dolls know in future generations, why do these people here know nothing?

I don't want to explain more.

But I don't know how to say it.

Zhang Feng sorted out his thinking, smashed his lips and said: "I can't tell you clearly. Well, I don't say it's so complicated. I'll just say one thing. This thing is a part of making fire gun, and it's also a very important part. As for fire gun, these things have to wait for the next step. Only by mastering the secondary superposition forging and the gun barrel poured out after secondary smelting, can they be counted Make a complete fire gun. "
