Gao Yiye slowly walked to the position of about half a step behind Li Daoxuan, and stood still, just like the two female secretaries in the autumn and winter when they stood behind her.

Next, Thirty-two, Tan Liwen and other people who worked in the main fort also heard the sound, and after a while, people like Cheng Xu and Wang Er who were outside the main fort also came, and the small craftsman well was full of people, all surrounding Li Daoxuan, and the momentum was really huge.

Li Daoxuan thought to himself: I sat here to get my nails trimmed, but as a result, so many of you came to watch, which made people feel so uncomfortable.

He was about to complain and let the guys scatter.

I saw Xu Dafu, director of the Firearms Bureau, coming out of the crowd, this guy walked very carefully, looking left and right, looking like he was about to walk into the tiger's den in Longtan.

Li Daoxuan smiled at him and said, "Xu Dafu, why are you careful like this?" ”

Xu Dafu: "Qiku Tianzun, although there is the blessing of Tianzun here, after all, where weapons such as knives and guns and firearms are made, there are murder weapons everywhere. If the villain is not careful, if he touches something that should not be touched, the sledgehammer will fall down, and he will also stone me to death. ”

Everyone: "......"

There is no reason to talk about this guy who is afraid of choking to death when he drinks saliva, Li Daoxuan: "You got out of the crowd, you have something to say, right?" ”

Xu Dafu excitedly took out a small round ball from his arms, and held it with both hands: "Fire hat, the villain has finally succeeded, using the strange gunpowder that Tianzun gave me that will explode when I fall, and repeatedly blending it, finally, hehehe, I made this thing that is placed in the chamber of the gun and ignites when the firing pin hits." ”

As soon as he said this, the attention of everyone who played with technology turned around.

Look closely at what he's holding in his palm.

It was a very small thing, only the size of a fingernail, and it was not a pure round, it was the shape of a round cake.

When Li Daoxuan looked at this shape, he thought to himself: This is the small piece at the bottom of the "bullet", when the trigger is pulled by a modern firearm, the spring pushes the firing pin and hits the bottom of the bullet, that is, it hits the fire cap.

When the fire cap is hit, it burns, igniting the gunpowder, and when touched, the bullet is pushed out.

Li Daoxuan was still thinking about these technical problems in his heart, and saw Li Da take out a fire gun from the blacksmith shop.

This is the early rear-loading rifle that Li Daoxuan gave him to make when he first met him, the Chasebo rifle, after solving the problem of the spring, it is not difficult to build this firecracker, the difficulty lies in the bullet.

Now that the fire cap problem is solved, it is equivalent to the bullet problem being solved.

Xu Dafu compared the chamber of the Xia Sebo rifle, took out a piece of paper, and began to make bullets on the spot.

In the early days of rear-loading rifles, all "paper-wrapped bullets" were used, which were basically hand-wrapped, and the bullets were very large, more than twice as large as copper bullets.

The front end of the bullet is wrapped with a small lead bullet, the middle part is black powder, and the back part is a fire cap.

Li Da opened the chamber of the gun and loaded the paper-wrapped bullet that Xu Dafu had just wrapped into the chamber, and the whole process only took a few seconds, which was much more streamlined than the complicated loading action of the front-loading rifle.

Then he picked up his gun and aimed it at a wooden target on the wall on the other side of the craftsman's well.

The trigger was pulled, and there was a bang, and a large hole appeared in the middle of the target.

The clerks present couldn't see anything, but Cheng Xu and Wang Er applauded violently: "Good thing, good thing, the loading speed of this thing is faster than ordinary firecrackers, I don't know how many times, it's too powerful." ”

Wang Er: "The rifled guns, because the loading speed is too slow and the attack interval is too long, so we dare not equip the militia in large quantities, so we can only let a few people use it, and the main force still has to use smoothbore guns to ensure the rate of fire." In the future, once the master uses this kind of gun that can be loaded with bullets in the back, there is no need to worry about rifling affecting the load. ”

Cheng Xu nodded: "In other words, all of our smoothbore guns can be slowly eliminated and replaced with this kind of breech-loading rifled gun." ”

A whole bunch of new tactics immediately flashed through the minds of the two......

However, Song Yingxing, who was not far away, spoke: "I think, there is a big problem with this gun. ”

Everyone: "? ”

Li Daoxuan's eyes lit up: Yo, do you see it?

Song Yingxing said: "The tail of this gun has a complex bracket, a firing pin, a spring, a slide and a lot of things, so that the air tightness of its tail is not very good, and the impact force generated when the gunpowder explodes will leak out from the edge of various brackets...... As a result, the force of its propulsion becomes weaker, don't you notice? The power of the bullet just now was weaker than the rifling of the front. ”

As soon as he said this, everyone suddenly realized that it was true that the power of this gun just now was lower than that of a rifled gun, and they only needed to look at the target to see it.

Song Yingxing sighed: "This problem, in fact, is also the problem that my steam engine is currently encountering, due to the poor air tightness, the steam made by boiling water, will also leak out from the various gaps of the machine, wasting a lot of power, if the problem of air tightness can be completely solved, then the power of this fire gun can exceed the front gun, and the efficiency of the steam engine will be greatly improved." ”

Li Daoxuan secretly praised in his heart: It is worthy of Song Yingxing, these eyes are quite sharp, but you have no way to solve the air tightness, with the materials science technology of this era of the Ming Dynasty, you can't do it.

As soon as he thought of this, he saw a strange look on Song Yingxing's face: "I just found a material that can be used to solve the problem of air tightness." ”

Everyone: "Speak up and listen." ”

Song Yingxing stretched out his hand and pointed at Li Daoxuan: "Use the material of the statue of Tianzun." ”

Everyone: "Poof! ”

It turned out that Song Yingxing reached out and touched Li Daoxuan's statue just now, and he was turning this idea in his mind at that time, Tianzun's statue material seems to be very convenient to solve the problem of air tightness......

"Bold!"

At least seven or eight people shouted at Song Yingxing at the same time: "What kind of crooked brains are moving in your head? Want to chop up the statue of Tianzun to mend the cracks in the machine? What a rebellion. ”

Li Daoxuan smiled: "Hahaha! Don't be so excited, Song Yingxing is an engineering man, he only thinks about technical issues, and doesn't think about other issues, you don't want to go online. ”

He smiled and said to Song Yingxing: "Compared with the material of my statue, there is actually a material that is more suitable for solving the airtightness of the steam engine and the rear-loading gun, but unfortunately your chemistry has not been studied to that point, so I will give you some first." ”

After saying this, in the next moment, his consciousness had returned to the body outside the box. Reaching out and grabbing the rubber that had been prepared a long time ago, he lowered it into the craftsman's well.
