Ai Tiezhu is just a fool, and he can't hide anything in his heart.

As soon as he praised Zhu Qi, he suddenly frowned again and said, "Prince, your idea is pretty good, but we can't make this thing."

Zhu Qizhu was secretly proud of this foolish guy's words, and he didn't get angry after being wrong.

He coughed awkwardly, then said angrily: "What can't be done, you said."

Ai Tiezhu pointed to the sketch and said without hesitation: "Just say that the bolt of the gun must be round inside and the outside must be round too. Otherwise, either the bullet cannot be loaded into the bolt or the bolt cannot be loaded into the hole of the gun."

This guy is a little stupid, but he is still impatient?

Zhu Qizhuo nodded in praise and said, "Yes, what's wrong?"

Ai Tiezhu pointed to the barrel of the musket in his hand and said helplessly: "Prince, you can understand when you look at the barrel. We can only ensure that the inside is round. Not only does it need to be welded on the outside, but it also needs to be knocked and hit, which cannot be round."

Zhu Qizhu was completely stunned when he heard this.

He had just looked at the barrel carefully. The surface was indeed bumpy. If you use this method to make the bolt, it would be impossible to closely cooperate with the components on the butt stock.

What to do?

It seems that I have to change the processing method.

Just have to have a lathe now. Cast an iron rod, drill the inside and a truck outside, then press the sand with sand and sand, and the two sides will be basically covered.

Problem, I don’t even have electricity these days, and even if there is a lathe, I can’t open it!

By the way, there is also steam machine tool, which he seems to have seen in some book.

It seems that there is a novel that comes from the steam piston and all the way to the steam machine tool.

To be honest, he watched that passage for a long time before he understood it, because he was not a mechanical professional, and it was really hard for him to understand those things.

It's hard to understand something, do you do it?

He just hesitated for a moment and decided to do it!

Because, he knew that if he didn't do it, he would do it.

The countries in the continent are about to begin the crazy steam era. At that time, they will build strong ships, powerful guns, etc., and you are still playing with local guns, and you will not be bullied to death!

Therefore, it must be done, no matter how difficult it is.

If you do it, even the European powers will work together to make a comeback!

However, as soon as he thought about how to get the steam engine out, he was stumped.

Because he doesn't have copper in his hand, he needs too much copper to build a steam engine. He has to use copper for steam pistons, pipelines, and steam boilers.

Copper is more difficult than iron these days, because copper coins are made of copper, and cannons are also made of copper, and the imperial court's control is stricter than iron.

How to do it?

It seems that it is impossible to start immediately, so he can only ask Ai Tiezhu to lead his blacksmith to build a crossbow first.

The power of the hand crossbow is not very large, and the attack distance is not very long. The only advantage is that the speed of installing crossbow arrows is very fast. Ordinary people can almost do it in seconds if they practice it a little.

With this thing, there will be attack methods with a distance of less than fifty steps. If you use muskets and artillery, it will be short, medium and long, with full coverage, and fight, it will be a slap.

Because of its complex structure, it creates troubles and is not very powerful, the Ming army has not equipped many Ming army.

However, it doesn't matter if the red weapon is rubbish. After all, it will take a long time to make a new musket. If it is a cannon, it won't even be even a shadow. He can't let his blacksmiths stay idle and wait for the steam machine tool, right?

After arranging the matter of making a crossbow with Ai Tiezhu, he hurried back to the royal palace and ordered someone to summon Huang Weixian to come and meet him.

Huang Weixian was very energetic during this period, because the little prince Zhu Qizhu handed him over all the iron smelting and selling pig iron. Moreover, pig iron was calculated based on the black market price, and the extra bonus belonged to him.

In other words, even if all the pig iron he refined was sent to Aijiafang, the little prince would calculate the money for him. Apart from the money for the mine, it would be no problem for him to earn about 5,000 taels a month.

In the past, the reason why he was unable to get up even if he could not get up was that 10% of the profits of the Baotou iron ore and coal mine were not enough to pay wages to the people he hired.

At this moment, he didn't have to worry about wages. The iron mines, coal mines, and iron smelting were all under the young prince's men. They didn't even bother to work hard, but they didn't want him to pay a penny.

He has only been working for a few months and has earned more than 20,000 taels a little. He has also wiped out his original decadent momentum and is very energetic.

When Zhu Qizhuo saw Huang Weixian's smart and capable appearance, he couldn't help but nodded slightly. This person is indeed quite good, and he is quite reliable in doing things.

For example, he never cared about refining private iron, so he let Huang Weixian make trouble in his original nest in Neixiang. Not only was the private iron refined quickly, but it was of good quality and quite large quantity.

Leave the business in secret to this guy to manage, and there will be no problem.

He thought for a while and then said, "Weixian, how about the new mining supervisor? Is it easy to deal with?"

Huang Weixian said with a little disgust: "Prince, they all have the same virtue. As long as the money is in place, everything is easy to say."

Zhu Qizhuo smiled and said, "Oh, that's good, it's still 60,000 taels per month, right?"

The little prince started laughing again!

Could it be?

Huang Weixian couldn't help but say in surprise: "Prince, are we going to grab it?"

I'm so stupid, who told you that this has finally attracted the attention of the corrupt officials of the Ministry of War to Guanzhong. If you rob me again, even if you are stupid, you can guess that there is something wrong here.

Zhu Qizhe shook his head slightly and said, "I won't rob it. For the time being, the silver is enough, so there is no need to take risks anymore. I'm looking for you, mainly to ask, Nanyang, if there is a copper ore bag, will you smelting copper?"

Copper mine!

When Huang Weixian heard this, he couldn't help but be surprised and said, "There is one copper mine. It's right on Tongbai. I can find an acquaintance with copper smelting, but the price of copper mines is scary! The copper mines in Tongbai have been covered for many years, because no one can withstand such expensive mine loan costs."

It is understandable that copper ore is expensive.

Because, as long as you are brave enough to open a mold and cast copper coins directly, it is equivalent to digging for money!

Zhu Qizhu said lightly: "How expensive? It scares you so much."

Huang Weixian stretched out a finger and exaggeratedly said: "At least 100,000 taels per month!"

One hundred thousand taels?

This is indeed a bit expensive.

Damn, it takes 160,000 taels to spend just copper mines, iron mines, and coal mines in one month. These dead eunuchs really want to steal them a few more waves!

Fortunately, sweet potatoes and potatoes will mature one after another next month. If you add private salt transactions, you will barely lose money every month.

Alas, it’s not a big deal to make as much as you earn.

Zhu Qizhuo thought about it again, then asked: "Do you still have any contact with the private iron seller?"

When Huang Weixian heard this, he couldn't help but say excitedly: "Prince, do you want to sell private iron?"

Zhu Qizhuo nodded slightly and said, "Yes, we don't need too much iron yet. The inventory in Aijiafang has been enough for us for several years. We can do private iron transactions, and at least we can get some money back. I just don't know if you can contact us if you old customers."

Huang Weixian nodded excitedly and said, "Yes, I don't need to contact me. Many people have come to me secretly, but I just don't have the goods to give them."

Zhu Qizhuo heard this and said decisively: "Okay, from this month, all the private irons will be sold. In addition, you go find the dead eunuch to wrap the copper mine of Tongbai."

Damn, one month is one hundred thousand taels a month. At worst, you can make some copper coins to make a return.
Chapter completed!
