The three of them came to the edge of the school field, and then set up a rectangular template about a hundred meters (thirty-three zhang), Yang Tingjian took the gun and began to load, while explaining to Shen Lian and the onlookers:

"The Kamui Musket has a total of five loading steps,

1. Pull off the hammer under the chamber.

2. Turn the crank on the right side of the gun, and the chamber is externally rotated up.

3. Take out the paper shell from the ammunition bag, and then tear off the paper cap at one end of the paper shell with your mouth.

4 paper shell bullets are stuffed into the chamber.

5. Turn the crank, return the chamber, insert the barrel, and complete the locking.

…… Do you understand? ”

Shen Lian and the three of them all nodded, indicating that they understood, the loading action of this Shenwei musket was a few fewer reloading actions than the musket they usually used, and there was no need to tamp the gunpowder loaded into the barrel through the strip, and the whole loading action was very fast.

Of course, Shen Lian and them, as Jinyi guards, usually have a lot of opportunities to use muskets, and they found a very special difference, that is, Yang Tingjian used paper shell bullets, and the gunpowder and bullet were wrapped in paper in advance, this idea was so ingenious, and the three of them couldn't help but applaud their masters.

"My lord, your paper shell bullet is simply too easy to use, just this paper shell bullet can more than double the rate of fire."

"Of course, it's useless to shoot fast just because it's fast, and it depends on the power and accuracy, so let me shoot you first!"

After Yang Tingjian finished speaking, he aimed at the target a hundred meters in front of him, and the loud sound of "bump" almost deafened people's ears, and the wooden planks in front of him also splashed sawdust, and a fist-sized hole suddenly appeared.

This power, this precision scared Shen Lian and the three of them at that time, in fact, this hole was already in the left position, and Yang Tingjian was in the middle of the aim, and it seemed that he still needed a school gun.

Shen Lian and the three of them all ran to the front to look at the plank, while Yang Tingjian took out a small wrench and gently adjusted the aiming circle on the top of the barrel, according to the displacement of the impact point just now, you can know how much position needs to be adjusted, if you have an accurate measurement tool, you can completely calibrate the gun in one step.

After Shen Lian and the others finished reading the situation, the faces of the three of them were all emitting red light, and Shen Lian asked impatiently:

"My lord, will our Jinyi Guard be equipped with this kind of divine musket in the future? This musket is so powerful. ”

Yang Tingjian replied with a smile:

"Of course, in the future, we will not only be equipped with this Shenwei musket, but also with Shenwei cannons."

At this time, even Lu Jianxing was shocked, and hurriedly asked:

"My lord, what are we doing with the cannons of the Jinyi Guard! If Your Majesty knows about it, I'm afraid it's going to be in trouble. ”

"Lu Baihu rest assured, this is allowed by His Majesty, and if it goes against the holy decree, I, Yang Tingjian, will not do it yet."

Although Shen Lian and the three of them are Yang Tingjian's apprentices, it is absolutely unrealistic to let them, the hereditary brocade guards, Chongzhen, at least for now.

Le Yichuan took over the conversation and continued:

"That's good, as long as we have muskets and cannons in the future, if anyone is not convinced, we will go and destroy him."

As soon as Le Yichuan's words were finished, he was kicked on the ass by Shen Lian:

"Second brother, why are you kicking me?"

"Pig head, you know how to fight and kill at night, can't you use your brain more? Our emperor is pro-army, not robbers and bandits. ”

"Oh......"

"Huh...... Then go to a wooden plank of sixty zhang trees......"

(In order to make it easier to read, in the future, the unit of rice will be used, and in ancient times, it was used in zhang and step.) ）

After more than a dozen tests, the Shenwei musket can hit 500 meters away, but it is no longer very powerful, and the accuracy is even worse.

At 400 meters, the impact point deviated by about six centimeters, which was barely acceptable, and at this time, the Shenwei musket could penetrate a three-centimeter-thick plank, and this power would have no problem killing an unarmored enemy.

At 300 meters, the bullet point deviates by four centimeters, and the Shenwei musket can penetrate a six-centimeter-thick plank, and the enemy wearing two or three layers of leather armor will definitely not be able to block the penetration of the Shenwei musket.

At two hundred meters, the point of impact is only one centimeter, and the power of the Shenwei musket is getting stronger and stronger, and the ten-centimeter-thick wooden plank can penetrate it, and the enemy with a layer of iron armor is definitely only a dead end.

What if the enemy is 100 meters away? At this time, the Kamui musket can penetrate sixteen centimeters thick wooden planks, and enemies wearing two or three layers of iron armor will have to die.

Yang Tingjian looked at the hot eyes of the three apprentices, and knew that the three of them also wanted to try, so he casually handed the musket to Lu Jianxing:

"You three can take it and practice on your own! Practice according to the movements I just did, but I don't have a lot of ammunition right now, so I can use it more leisurely...... During this time, I can't relax in the queue training, and I have to teach the craftsmen how to make this musket. ”

"Your Excellency, don't worry! I can't keep it wrong. ”

In the next ten days, Yang Tingjian taught the selected recruits how to make muskets and use machine tools. This is not an easy job, even if it is just to teach them how to use it, Yang Tingjian needs to explain and demonstrate countless times before these recruits can barely do it.

Of course, these recruits don't have to return to the army, but Yang Tingjian's secret craftsmen, there must be no problem with their loyalty, even if there is a problem, they know the method of making muskets, but without modern machine tools, they can't reveal the secrets of Shenwei muskets.

After these craftsmen learned the basics, they made very few qualified parts, and Yang Tingjian had no choice but to let them continue to practice and guide them on the side, but fortunately, the seamless steel pipes that Yang Tingjian brought back from modern times were relatively sufficient.

Even the scrapped seamless steel pipe is also useful, after re-melting, you can use the stamping machine tool to create other parts of the musket, such as spring blades, triggers, etc., and the remaining leftovers Yang Tingjian will not let go, and it will also be used, because at this time, Daming's steel can't make a good musket at all, and Yang Tingjian can't afford to waste it!

As for artillery, it is relatively simple, because the Fran machine cannon is no secret in Daming, these new craftsmen have also seen it, and even the physical Yang Tingjian has also found one, which is more intuitive.

Of course, the Shenwei artillery was also the first to be manufactured by Yang Tingjian, the barrel is one meter and a half long, made of 120 mm seamless steel pipe, and the rifling is cut out with a machine tool, and the craftsmen have mastered it, and Yang Tingjian does not need to bother.

The gun chamber is made of 130 mm seamless steel pipe, and then welded to the gun barrel, of course Yang Tingjian will use it, but these craftsmen can't, they don't need to understand the principle, Yang Tingjian is only responsible for teaching them to use, as long as they are not stupid, they can still learn.

Yang Tingjian is equipped with ten sub-guns for each gun, and the sub-guns are of course 120 caliber seamless steel pipes.

Yang Tingjian selected 120 mm and 130 mm seamless steel pipes, the wall thickness of 120 mm seamless steel pipes is 5 mm, and the inner diameter of 130 mm seamless steel pipes just coincides with the outer diameter of 120 mm seamless steel pipes.

[Note; Scientific testing shows that the gap between the wisdom of the Ming Dynasty and the modern people is only a few percent, and those who say that the modern people are much smarter than the ancient people can rest, and the gap between the Ming Dynasty and the modern times is science and technology, not the wisdom of people.

Falling leaves said this to show that the people of the Ming Dynasty could definitely use CNC machine tools and steam generators skillfully under the teaching of the protagonist, but they didn't understand the principle and why a wire could make a machine tool work.

But does Yang Tingjian need them to understand? Not at all, as long as they can use the CNC machine tools that Yang Tingjian bought, the Ming Dynasty's smart Cheng dù is enough for them to learn the machine tool operation knowledge given to them by Yang Tingjian. 】
