Before Zhang Yingquan left Zhan's house, he handed over the peach wood mountain card that roared six to Zhan Yuqing, and advised: When you encounter mountain bandits again when you go to the goods, show the mountain card, it works!

Then he took Zhan Erlian back to the mountain town together, and there was a shortage of scholars who could write and calculate in Zhangjia's craftsman's shop. Although his addiction to smoking in the past two days is much smaller, it is because he has not smoked for a long time and can be controlled, and he dare not say that he has completely eradicated it. There is no big smoking in the mountain town, and there is a foreign doctor John, who has many benefits for quitting smoking.

The shopkeeper Zhan is grateful in his heart, he is thinking about the Zhan family!

"Then ...... No thanks! ”

A few days after leaving the mountain town, there have been many changes, and the affairs in the shop are in order, after all, there is a daughter-in-law who is educated and can run the house.

The ash is still made, Zhang Hengshan finally found self-confidence, I don't know if he is a precedent in the Qing Dynasty, at least there is another core product in his hand.

With it, the so-called Ande Mansion is not a dream.

The matter of the Baoquan Bureau was dealt with quickly, what 'when fifty'? Don't worry about it! As for the title of the Nine Rank Master, what is it? The small officials who don't enter the stream can't look down on it at all, and few people in the mountain town know about it, so they can't afford to lose that person! The so-called 'rather be a chicken head than an oxtail', not to mention the back of the ox's tail, a small miscellaneous hair at the very end.

Zhang Yingquan focused on the matter of building guns.

Long hair may also hit Jinling next year, in his later teaching books, only two or three years after the Taiping Army uprising in Nanjing, a catastrophe is getting closer and closer to Zhejiang, other things can be put away, this gun is a strong man's weapon, can not be without, first made, grasp in the hand to have confidence, a philosopher said: "The gun is out of power." I'm not going to deceive you!

At present, the guns equipped with the imperial firearms battalion are miserable, and they are still in the stage of arquebuses and guns, which are two generations behind, and the foreigners who show off their power in the land of the Qing Dynasty are not very well equipped, and they generally use front-loading flintlock pistols, that is, they can lower spears and swords and arquebuses.

From John's mouth, I learned that the mainstream equipment in the West is the front-loading flintlock pistol, and there are also new front-loading fire cap guns, and there is no generation gap in technology. The breech-loading gun is still under development, the rifled gun has not been heard, and later generations remember that it was in the last years of the Qing Dynasty, the technology that appeared during the Westernization period.

It is impossible to build a gun in one step, but it must not lag behind the world trend, and it is necessary to give full play to the technical conditions that we can master at present.

First of all, it is determined that it is a smoothbore gun, and the water-driven earthen machine tool can not pull out the rifling, even if the rifling is cast by the lost wax method, polishing is also a big problem.

Secondly, consider the breech fixed gun, which is the trend, the difference between the breech gun and the breech, like the cross-era musket revolution. Although the technical difficulty is great, it is not a cut that cannot be overcome, Zhang Yingquan has the theorem foundation of later generations, and the starting point is high, without hesitation.

It adopts the latest Western fire cap firing technology.

The little brother of later generations has only touched guns such as automatic rifles during military training, and has never studied the guns used by his predecessors, which is designed out of thin air! Fortunately, the principle is the same, I have professional knowledge of machining, people say 'interlaced as separated mountains', and some people say 'interlaced is not separated', everything can not stand up to pondering.

First, use wood to stake out, determine the size of each part, simulate mechanical action, and determine the accuracy of the 'fit' of the breech, as well as the degree of locking and fitting of the bolt. The whole gun is divided into: fixed breech (barrel), detachable sliding breech, slide rail, bolt lock, trigger, firing machine, etc.

The most troublesome thing is the firing device, if there is no mercury material, you have to find another way.

Fortunately, John is an expert in chemistry and is also interested in this, he does not advocate the use of mercury, one is that mercury is toxic, its chemical properties are extremely unstable, easy to go off, and there is indeed no mercury material here.

He formulated a new gunpowder, which turned out to be a technology for matches, that is, matches that could catch fire with a single wipe without red phosphosphor skin. The stability of this gunpowder is relatively good, and strong impact can also deflagrate, strong impact is not a problem, and the strength of the steel spring can be strengthened, but the vibration will affect the shooting accuracy, but this is the best solution allowed by the current conditions.

Of course, most of the components are still cast with the most mature and skilled skills - lost wax method, so that the parts made in this way have guaranteed dimensional accuracy and can be interchanged, and assembled after grinding, charcoalizing, quenching, and baking!

Add wooden butt, with spear stab (the head of the gun can be equipped with a single-edged bayonet).

This is not over, there is still a problem ahead, that is, fixed ammunition.

If we refer to the bullets of later generations, without complete sets of machinery and equipment, if you want to mass production, you can't dream of it.

There is an alternative: first carefully make a batch of steel or copper shells, since it is not possible to make a big belly like the later generations, it is also feasible to make a general coarse and lengthened one, nothing more than to lengthen the breech design accordingly, so as to ensure the amount of charge.

Rounded rear small trumpet-shaped warhead. When the bullet is fired, the horn is in the back, which plays the role of sealing the gas. When the bullet flies, the gravity is in the front, and the horn plays a role in stabilizing the fall. This design refers to the principle of the air bullet of later generations. The bullet is dipped in paraffin, stuffed into the shell filled with gunpowder, half of the head is exposed, and the fire cap is stuffed into the bottom eye, which is a complete bullet.

But this kind of bullet can only be manufactured in small quantities, the cost is too high, not to mention, due to the high precision required, the amount of labor is also large, relying on manual mass production is simply unrealistic, can only be less than a few bullets per gun, and prepare gunpowder, warheads, fire caps, after shooting, recycle the cartridge shells, and charge their own charges, warheads, and fire caps. In fact, it is not difficult to charge, isn't the breech gun its own charge? The same process is just a temporary charge, a pre-loaded, this design, as well as the idea of repeated use, made John also surprised, praised: Oriental people are too smart!

When the guys were there, the most excited was John, in the face of murder weapons, he didn't seem to be a clergyman, but he could also understand that he was a chemist interested in technology, and gunpowder was prepared by him, among which this smokeless gunpowder was still made according to the production method provided by Zhang Yingquan, which was very simple to say, Zhang Yingquan remembered a story in later generations, the content was to soak cotton in nitric acid and sulfide liquid, and dry it to become smokeless gunpowder. At first, I was skeptical, but after a try, it was like discovering a new continent. According to John, this is definitely a new discovery.

"Bang!" John fired the first shot.

The wooden target of one hundred and twenty paces overturned in response, and another hundred and fifty paces.

"Bang!"

"Bang!"

Two hundred steps, the effective range can reach two hundred steps, that is, one hundred and fifty meters in later generations.

Among all the people present, only Zhang Yingquan disdained, shot a shot, pulled the bolt back, stuffed the bullet, pushed the bolt down, and shot again... Again..., this is an antique in later generations, the 'old sleeve' and the 'singles one', or the kind of old tooth goods without rifling.

In John's eyes, this is absolutely invincible artifact, roughly estimated, every four ~ five seconds can complete a shot, those guys with breech guns, it's time to go home and rest!

The sound of gunfire echoed through the valley.

This gun has a name that can't be more foreign: SHH1852-1G

It means "S", "H", "H", "H", 1852, "G", a type of gun.

The people in the craftsman's shop, a black line!

The second brother didn't understand, and he didn't want to understand: "What 'love snipe' and 'love snipe' are called 'sniper' guns!" ”

"It's a good name, it's called the 'Sniper' gun."

"Huh?"

Zhang Yingquan gathered the people involved in the gun making and declared:

First, the performance of this gun must be kept secret.

Second, for everyone, including wives and children, the caliber is the same, so it is said that this gun is a Nanyang shotgun, which is obtained from foreigners.

Everyone understands, what is the crime of making weapons privately, and you can't run away from any of them after deep investigation, even if the emperor is far away, you can't publicize it, even if the official family doesn't pursue it, recruit you to serve hard labor in the Firearms Bureau of the Ministry of War, and build muskets for the imperial court, can you refuse? Surely I can't live in peace!

It is difficult to say that the people in the mountains are innocent of holding foreign shotguns, and they are more advanced than the Qing army or even the foreigners.

In addition, these five guns are enough for testing, and the family has a thin foundation that cannot be wasted, and the manufacture of breech guns will start tomorrow.

Why?

The breech gun has a low cost and high output, which can be used for training, self-defense, and money! The guns are high-profit, and foreigners are not soft to earn silver, so they don't take us with us? As for how to skillfully 'export to domestic sales'? Hey~! Just make an idea in John, a real foreign priest.

The breech-loading musket cap gun is currently considered advanced, at least one step further than the breech-loading flintlock pistol currently equipped with mainstream equipment.

The breech gun is much simpler than the breech gun, the main part is basically a barrel, and after casting, there is only the work of grinding, of course, there are fragments of the hairpin and trigger, how many barrels are cast in a day, how many guns are basically made, and there is no problem in making an average of twenty guns a day, which is in Zhang Yingquan's eyes, it is silver, silver with white flowers.

It's time to talk to John once.
