After visiting Wu Yuechan from Yin County and returning home, Zhao Qi stopped going out. He locked himself in the study and wrote and painted for seven or eight days, and made a lot of drawings.

"It's probably about the same!"

Looking at a musket drawing in his hand, Zhao Qi stretched and stood up.

As a time traveler, firearms are naturally a must-have. The structure of this thing is simple and not difficult to manufacture. The craftsmanship of the Song Dynasty is enough to build. The quality of steel smelting is not up to standard, the casting process is not good enough, and there are no equipment and machines such as lathe milling machine grinding and polishing. It relies entirely on hand manufacturing with poor accuracy and output, but no matter what, you have to make a few rods first to see the effect.

If you want to confront the Mongolian army in the future, you have to make sufficient preparations in advance and start working hard to make some technology trees.

If a traveler who has seen too many aircraft, cannons, tanks and machine guns, has to compete with ancient people with pure power such as swords, guns, sticks, and bows and arrows, it must have been that his head was wormholes when traveling through time.

Put a stack of drawings in a handbag and go straight to the blacksmith shop in the village.

Now Xiaolongwan Harbor has completely gotten on track, and the main pressure of logistics services is no longer tools and manpower, but building materials. Therefore, Yang Dahu's work has also been much easier. He spends most of his time in the blacksmith shop in the village to train his disciples.

The main job of the blacksmith shop is to help the carriage factory build axles, turn rivets and collars, and this summer and autumn grain harvesting begins to use threshers. In order for the threshers to be more practical, some big dog owners also require steel to build a central axis, which has led to a large number of orders in the village, and ordinary sickles and hoes are too lazy to take orders.

When Zhao Qi came to the blacksmith shop, Yang Dahu was wearing a bare-handed leather skirt and was smacking irons with several apprentice helpers. When he saw Zhao Qi coming, he handed the hammer in his hand to an apprentice.

"Xiaoqi, why did you suddenly come to me if you have time?" Yang Dahu wiped the sweat from his forehead.

"Uncle Dahu, I have a few things I want to ask you to help create..."

"You want something, just ask someone to say, why don't you invite me?" Yang Dahu interrupted Zhao Qi with dissatisfaction.

"It's really hard for others to explain this. Uncle Dahu, come and see!" Zhao Qi walked under the awning and took out a drawing.

"This... what are these things?" Yang Dahu picked up the musket picture, looked around several times and found that he didn't know what it was.

"Uncle Dahu, this thing is called a musket, and it is used to kill people!" Zhao Qi said in a low voice.

"Murder?" Yang Dahu's face shook his hands and was nervous for a moment. He quickly lowered his voice and said, "Xiaoqi, are you in trouble? It's better not to do this kind of thing in person. Who do you want to deal with? Let me tell you, Uncle Dahu helps you think of a solution, find a few thugs to kill them at night and throw them into the sea and even the gods can't be found?"

Zhao Qi was amused and crying.

"Uncle Dahu, I didn't say I wanted to kill someone. There's no trouble recently. Are I doing well?"

"Then why are you doing this strange thing?" Yang Dahu breathed a sigh of relief.

"On the Mid-Autumn Festival, I saw people setting off fireworks. They put gunpowder in bamboo tubes. After igniting the lead wire, the fireworks will be sprayed out from the outlet. The cigarette cartridges inside are even enough to spray up to a height of more than ten feet. I have been idle lately, so I thought that since the fireworks can be sprayed out, if we use steel to make a pipe, fill it with gunpowder, and then install iron bullets, can we spray it out far after ignition? If these iron bullets hit people, they might be able to kill people..."

"Uncle Dahu, look, this is a gun barrel. It must be made of good cooked iron. It must be firm. Below this is a wooden stock. Fix the iron pipe on the stock. The gunpowder and iron bullets are loaded from the barrel..."

Zhao Qi pointed to the drawings to introduce it. Although Yang Dahu was skeptical, he still nodded constantly.

Zhao Qi is now an all-round person in Maowan Village who appears in the minds of the mountain god. He is omnipotent and omnipotent. He is also the leader of their group of people getting rich. Many people have even begun to discuss privately that Zhao Qi will be elected as the village official in Maowan Village.

Therefore, Yang Dahu would not refute Zhao Qi's whimsical idea at all. Moreover, Zhao Qi is not nonsense. The reason is indeed valid. Fireworks can be sprayed more than ten feet away. If you use a solid iron pipe, use more gunpowder, and spray it out to injure people.

After understanding the basic principles, Yang Dahu pointed at the sight, trigger and hammer in confusion and asked: "Xiaoqi, then what are these extras?"

"This is called a sight. When we shoot an arrow, we usually aim at the target with our eyes in the direction of the arrow when we pull it open. This sight is used to aim at the target..."

"The one behind is called a hammer, and the one below is called a trigger. These two form a linkage mechanism. As long as the trigger is pulled, the punctured hammer will fall and hit a piece of flint at the fire door. The splashing sparks can ignite the gunpowder on the fire door, and then ignite the gunpowder in the barrel, and then blast..."

Zhao Qi pointed his hand forward.

"The gunpowder ignites and explodes, and it will spray all the iron bullets in the barrel, and then hit people with crackling sounds!"

"Uncle Dahu, do you think my idea is good?"

Zhao Qi looked at Yang Dahu.

Yang Dahu looked at the drawings in his hand with a confused face for a long time, then slowly organized the picture described by Zhao Qi in his mind. Finally, he touched the beard with a steel needle on his face and nodded vigorously, "Xiaoqi, your idea is definitely fine, but it is very troublesome to do it. It's easy to say that the barrel of the gun is, and it's just cast a piece of iron..."

"Uncle Dahu, it is probably unsafe to cast the barrel. There may be trachoma. If the gunpowder is put too much, it will explode. However, if the gunpowder is put less, it will be afraid that the iron bullet will be sprayed out without strength and will not hit far. However, it does not require too high strength at the moment. If it is cast, it will have to be reprocessed and forged. Look at these drawings..."

Zhao Qi took out a few pictures from the bag, each of which was placed on a shabby wooden table.

"Whether this musket is very powerful or not has much to do with the quality of the barrel. Therefore, the most important part of this musket is the barrel. In order to create this barrel, we designed a special grooved anvil and concave hammer..."

"You first cast the iron pipe, and then use a straight steel bar with a diameter of four minutes into the middle to continue forging repeatedly, striving to ensure that the iron pipe has no cracks or trachoma. In fact, it is best to make it completely forged with cooked iron..."

"As for hammer and trigger, look at this one..."

Zhao Qi pointed to a side sectional view with a musket trigger and hammer drawn.

"The mechanism between the hammer and the trigger is not complicated. A clamping wheel and a shrapnel. When the hammer is broken up, the clamping wheel rotates to press down the shrapnel. When the trigger is pulled, the clamping wheel will release it, and the shrapnel will bounce up and hit the flint with the hammer..."

Yang Dahu understood quickly.

"Xiaoqi, what you said sounds like nothing wrong, but it will take a lot of effort to do it!"

"Of course, these things are very small in size and require very fineness. It is indeed not easy to combine them together to work, especially this shrapnel must be very thin and elastic. Just like a steel knife, it cannot be easily bent and broken. But you can take these slowly. Don't worry, Uncle Dahu will first help me build a barrel, and then help me get some iron sand and lead tin. I will verify whether it can be used first. The size and style of this barrel are here..."

Zhao Qi pointed to a picture, and the barrel was drawn on it, and it was marked with length, aperture and pipe wall size data.

"After the barrel is built, it is required to be straight, the inside is required to be smooth and there are no burrs. The tail end must be nailed into the iron pile to block it without gaps or cracks. Finally, it is to drill a hole, use the hardest steel to create a drill bit, drill the fire hole at the position of the fire door..."

"Drilling?" Yang Dahu's face shook violently.

"Well, it's actually not difficult to drill out. I have also designed a lathe for drilling..." Zhao Qi took out a few drawings from his handbag and placed them one by one on the table.

Looking at these more complicated drawings, Yang Dahu felt his hands and feet were a little weak and his head was a little lacking in oxygen.

"Uncle Dahu, these are all lathes designed by me. They have different functions, including drilling, polishing, cutting, and polishing. The structure is very simple..."

These lathes are really simple. The so-called lathe is just a few simple tools for stepping on foot or hand-cranking. The drilling lathe is a hand-crank drill bit, but it has an additional fixture, and the polishing, cutting and polishing are almost the same.

"Don't worry, Uncle Dahu, these are really simple. In fact, they are similar to threshing machine and spinning machine. They just have changed some of their uses and structures. If you don't understand it, go to the carriage factory to ask a few carpenters..."

Zhao Qi muttered and whispered to introduce these lathes and then flipped the handbags. Yang Dahu covered his heart and gasped beside him.

"Okay, nothing, that's all right now!" Zhao Qi shook his head regretfully after flipping through the bag.

"Huh~" Yang Dahu breathed a long sigh of relief, shook his forehead and said with a pale face, "Xiaoqi, if you made all these, it would probably take a few months. I still can't understand some of these pictures!"

"Uncle Dahu, you're not in a hurry. Now you can get a gun barrel out and then talk about it. You can study the lathe slowly. If you don't understand, ask me. Also, don't tell me this. If others ask, you say it's what I want and don't know the use..."

"Don't worry, I won't say a word!" Yang Dahu nodded quickly.

"That's it. You have packed all these drawings and do them slowly when you have time. I'm not in a hurry. Just tell me if you make them out!"

Zhao Qi left, Yang Dahu sat under the dilapidated pergola, holding a beard like a steel needle, looking at the drawings all over the table in a daze.

He was very confused.

Last time, Zhao Qi just wanted to build a wasteland and built a warehouse, but it turned into a Xiaolongwan Harbor.

This time I just watched the fireworks set off, and it was even more overwhelming and made a bunch of things I couldn't understand at all.

If the musket is made and if it can really kill people, what does Xiaoqi want to do?

After a long time of dazed, Yang Dahu suddenly shivered and hurriedly put away a lot of drawings. Then he walked into the blacksmith shop and shouted to find the best cooked iron to prepare to open the furnace.
