He opened the notebook and began to flip it up one by one, the more he looked at it, the bigger his eyes became, the more surprised he became, and even his hands trembled when he looked at it, and suddenly he closed the notebook, held his hands above his head, and knelt in front of Yu Xiaotian with a plop, and said to Xiaotian with a trembling voice: "Big boss!" Thank you for giving such a baby to the little one! The great master god man also! Please take a small bow! ”

Yu Xiaotian accepted his worship, thinking that he knew the importance of this notebook for a person who loves machinery, if ordinary people don't understand machinery, they may use this notebook as waste paper to wipe their butts and think it is not soft enough, but as a blacksmith, he must understand the importance of this notebook.

So for Blacksmith Zhang, this book is a treasure, a treasure more important than anything else, and this notebook is very likely to open the door to an industrial age, at least it can be called a key.

This also embodies his countless days and nights of hard work, and now he hands it over to Blacksmith Zhang, and it is only natural that he will be worshiped by him.

After the blacksmith Zhang kowtowed, Yu Xiaotian stretched out his hand to pick him up, and said to him: "For the time being, you are still working in the gun, the name I gave you is the director of the gunsmith's technique, and he is only responsible for the craftsmen's craftsmanship and technical affairs, and I can't let you get rid of it all for the time being!"

This book,You must put it away properly.,Because I only have this one.,There's no second one! And you read this book for yourself first.,If you don't understand, you can ask me when you go back to see me.,I'll figure it out with you! It must be thoroughly eaten, and then gradually passed on to the apprentices, but it cannot be easily revealed, let alone let it flow outside! This is related to the future of our sea wolves, you must remember! ”

Blacksmith Zhang's face was flushed with excitement at this moment, and he nodded again and again and swore to the sky: "Please rest assured, the big boss has written it down!" This book is more important than a small life.,Small is death.,Can't let it be lost or destroyed! This small book will look at it carefully.,And then copy it down.,After the small copy is finished.,The small one will return it to the big boss immediately! Thank you to the big boss for trusting the small, the little one doesn't know how to repay the big boss in this life! As long as the small one still has a breath, this life is the big one! Wherever the big boss goes in this life, the little ones will follow! If there is a repentance, let the little one not die well, and everything must not be overborn! ”

Yu Xiaotian nodded and said, "It's good!" I trust you, that's why I'll give you this thing, you can copy a copy, and by the way, you can eat more things!

In addition, you can choose a few apprentices who like to do this, not necessarily very smart, but they must like to do this in their hearts, accept them as your apprentices, and pass on what you have learned to them, I don't want them to become masters, they will beat the iron very well, in that case, at most they are rough craftsmen, I want them to learn to think more in the future, to create new things, no need to do it themselves, as long as they can draw what they think, as for the manufacture of nature by others to help you do it!

I'm going to teach you how to make mechanical drawings, and I'm going to get some drawing tools! Well, so be it! ”

Blacksmith Zhang was so excited that he followed Yu Xiaotian's buttocks, at this time he almost regarded Yu Xiaotian as a god, and he couldn't wait to eat that notebook in his stomach to feel at ease.

Yu Xiaotian took a look at the production of guns here, and was quite satisfied with the production here, at least this place no longer looks like a workshop-style blacksmith shop, but has a bit of a factory feeling, this feeling is very good, even if it is hot here, he is willing to stay in this kind of place for a while.

Yu Xiaotian personally inspected several flintlock pistols produced, focusing on the operation of the flintlock mechanism, the accuracy and quality of manufacturing, and the other is the condition of the barrel.

After such a long time of exploration and training, the craftsmen of the gun have been quite experienced in making such a barrel, although the material is wrought iron, far from being comparable to the alloy steel of later generations, but in this era, even Europeans are using such materials to make barrels, but the life is relatively short.

In terms of process quality, the barrel that Seawolf is currently making itself is comparable in quality to the barrel quality produced by craftsmen from any country in the world of this era, so that another weapon he has been considering has initially met the conditions for production.

Yu Xiaotian took Blacksmith Zhang to a quiet place in the gun, stood still in front of a table, and said to Blacksmith Zhang: "Old Zhang, do you remember the incident I mentioned to you before?" ”

Blacksmith Zhang was a little dizzy with excitement at this time, and he didn't think of what Yu Xiaotian had mentioned to him before for a while, so he scratched his head and said: "At this time, the little one is only happy, and I can't remember what the big boss is referring to!" Please make it clear! ”

Yu Xiaotian sweated, smiled and asked Blacksmith Zhang to put down the notebook first, talk quietly, and then say to him after drinking a sip of water: "It is a gun that I brought up to you when I came, which can take people's lives two hundred steps away, and even fight farther, and it is a gun that hits extremely accurately!" ”

When Blacksmith Zhang heard this, he patted his head and said, "It turned out to be this matter!" The big boss can make the small one suffer, since the big boss mentioned this matter, the small one can't let go for many days, it's really a hundred claws scratching the heart, and I've been thinking about it!

The little one really can't think of any way, and he can hit the gun so far, and it is as easy as probing to take someone's life from 200 steps away! Later, I was too busy, so I gradually put this thing down!

Is the big boss going to tell the little one today, how to make this thing! Please don't sell it anymore! Tell the little one! In the future, the small ones will have idle time, as long as the big boss says it, the small one must hurry up! ”

Yu Xiaotian nodded and said, "That's right, after seeing your craftsmanship here today, I think I can leave this matter to you!"

Actually, the kind of thing I'm talking about is not much different from the flintlock pistol right now! Just carve a few lines into the wall of the bore of the barrel bore! I call it a rifled rifled gun......" Yu Xiaotian said as he spread out a piece of paper and roughly explained the rifling matter to Blacksmith Zhang with a charcoal pen.

"Grooves in the chamber? I'm afraid this is not easy to do! The barrel is so thick, how can it be carved? I can't get off the guy! If you carve a straight line, it's better to do it, you can get a knife for the small one, stuff it in and pull it out a few more times, and you can get it out!

But the big boss has to carve a groove on the inner wall of the gun chamber, and let this groove rotate, which is probably really difficult to do! The small ones have to think about it and think of a way!

But after carving such a few lines in the chamber of the gun, can it be possible to make the gun hit far and accurately? What's the point? ”

"This is actually not complicated, let's talk about why after engraving the rifling, the gun can hit far and accurately! ......" So Yu Xiaotian began to tell Blacksmith Zhang in detail about the role of rifling and the advantages of rifled guns, and after using it for a while, he finally understood the benefits of doing so.

"I see! I can't imagine how the big boss figured out these things, if there are so many benefits, then it is really powerful!

By the way, if you do this, I'm afraid this gun won't be easy to get! If it's too big, I'm afraid it won't fit into the barrel, and if it's small, there will be a few grooves in the chamber of the gun, and it will still be deflated? It doesn't work! After hearing this, Blacksmith Zhang finally understood the problem of the rifled gun, but he was now able to think about it, and immediately thought of the problem that existed.

Yu Xiaotian immediately thought of this question when he heard Blacksmith Zhang, and was really surprised by Blacksmith Zhang's reaction speed, and couldn't help but look at him a little more impressed.

"Good! It's great that you can think of that! But this matter is another thing to say, don't worry about it for now, the gun of the rifled gun is different from the gun of the straight smoothbore gun we make now, now we use the round gun, the rifled gun will be long, and the weight is much heavier than the gun of the current smoothbore gun! The mass is large, the muzzle velocity is large, the natural hit is far, and the flight is rotated, so it will fly naturally and steadily, this thing will wait for you to make the rifling, and I will tell you how to get it not too late.

As for the rifling problem, I've already thought about it, come on, bring me the drawings I drew during the New Year! Yu Xiaotian said.

Liu Wang immediately took out a roll of paper from a whale skin waterproof round leather bucket on his back, sent it to Yu Xiaotian, spread it out on the table, found a few wooden blocks as paperweights, and suppressed the drawings.

A mechanical sketch of a drill machine appeared on the paper and appeared in front of the blacksmith's eyes.

Blacksmith Zhang immediately lay down on the table, and like a dog that had been hungry for a few days and suddenly saw a bone, greedily began to study the sketch.

For an old craftsman like Blacksmith Zhang, who already has a certain amount of experience, Yu Xiaotian doesn't have to explain too much to him, and he doesn't have to draw a three-sided diagram to mark the size clearly, these details of things, Blacksmith Zhang will naturally improve it himself, he only needs to give him a general idea, which saves Yu Xiaotian a lot of effort.

As a military fan, especially those who like weapons, many people are very curious about how guns are made, especially how things like rifling can be made, so Yu Xiaotian is no exception.

Therefore, he still has a certain understanding of how to make rifling, of course, although he knows the way of modern machinery to manufacture rifling, but he has no conditions to make it, and can only use some primitive means and techniques to make this rifling.
