Poor family mother and son

What can't be done when people are pushed to the limit?Do you still use men and women?

That is to say, if Chu Qing knew the principles of these simple firearms, he would copy them directly, otherwise, Chu Qing would have to come up with something himself.

Right now, there are craftsmen who have come up with ideas for making firecrackers. If the imperial court pays attention to the innovation of craftsmen, Chu Qing estimates that it will not be difficult for them to equip the army with firearms within a few years.

It's just that, as Kang Xi said, the things he made spray sand, stones or iron filings, and the range is not far, and they can't penetrate soldiers' armor, so they don't do much damage.

How is this different from fireworks?

The research and development of a weapon needs to carry out a series of processes such as the development of pilot technology, key components and prototypes of manufacturing weapons, as well as the development of production processes, product manufacturing, and product upgrading, based on the premise of operational concepts and equipment requirements.

Different research and development and production institutions are required to participate in the process, each performing its own duties and cooperating with each other to jointly complete the development of weapons and equipment.

It is not enough to rely on one person's one idea.

For example, Kong Xi said that he installed his "frightened gallbladder" on the shaft of a long spear and pointed it at the cavalry's horse's head with a single blow, causing the opponent to turn his back on his back. This is based on the idea of ​​​​infantry fighting cavalry.

But Kang Xi is not a soldier, all he thinks about is the sudden effect of the fire and gravel sprayed out by "Scared", but he doesn't think about whether the infantry will have a chance to ignite the "Scared" when they are only one gun away from the cavalry. guts".

And this is also the limitation of "Scared Out of the Brave", because if the distance is extended, the sand and stones ejected will not cause much damage to the enemy's armor.

If you rely on the flames and high-heat gas to increase the damage, you will have to shorten the distance again.

Although Kong Xi also proposed the idea of ​​firecrackers, but under the premise that his "scaring the guts" can't create much power, no one would think of investing money, materials and time to try it.

And the most important point is that the quality of gunpowder itself is not too hard.

Coupled with the lack of strong demand for war, and the interference of middle-level officials such as bureaucracy, peach picking, and profiteering, the innovations of these craftsmen are not valued by Shangguan, let alone Shangda Tianting.

Presumably, this is also the reason why such items will not be improved and developed at present.

Therefore, under the premise that it is possible to develop firearms in this dynasty, the quality of gunpowder will become the decisive factor in combat power.

For the extraction of high-purity potassium nitrate from saltpeter, although the method is simple, and the process of redissolving-heating-cooling is sufficient, no one really knows.

After all, at the current level of science, no one should know the chemical and physical principles of producing potassium nitrate, and no one can distinguish potassium nitrate and sodium nitrate, two substances with similar chemical and physical properties.

Gunpowder can only be configured based on experience and feeling.

Otherwise, like Kang Xi and the others, they wouldn't form big dead lumps because the gunpowder was damp, and they would smash it into powder, and then cause an explosion, hurting people and themselves.

Agglomerated by damp, and formed large dead lumps, it can be seen that the proportion of sodium nitrate in gunpowder is too large.

Therefore, Chu Qing agrees with Master Lu's statement, unless he can rest assured that these craftsmen will not be exposed to black powder.

Then, the formula and production method of black powder have become the top priority that must be kept secret.

Compared with these skilled craftsmen, Chu Qing trusted Hou Ze and his group more, because he believed in Xiaobao's vision, Wei Chengyi and his father Shui Maomao.

"Mom, pistol, can you do it?" Xiao Bao looked at Chu Qing's diagram of the firecracker drawn on the ground, pulled Chu Qing to a distance, and Thieves asked quietly.

Chu Qing: "Uh... pistol, I can figure out the structure, but I can't make it."

Pistols and firecrackers are too different, Chu Qing thinks about it, and probably can draw a similar structure diagram, but in terms of practice, I'm afraid I don't have the skills and materials, right?

Xiaobao: "I don't want you to do it, there are these craftsmen!"

Chu Qing: "That belongs to precision craftsmanship, and the current processing methods cannot achieve it."

Xiaobao: "I'm not talking about modern pistols, like the thing you drew on the ground just now, smaller ones that can be held in your hand, make one?"

Chu Qing really had a blueprint in his hand. He stayed up late last night to draw a blueprint for a flintlock rifle.

The structure of the flintlock gun is not very complicated, but it is not easy to process. For example, at least four to five pairs of screws of different types are required, as well as a super hard spring, which needs to be manually ground.

The hardest part is rifling.

Without rifling, it is a smoothbore, with limited range and low accuracy, and it belongs to where to hit; with rifling, it can achieve a certain degree of accuracy, and there may be a chance to hit the bull's-eye.

How to design the rifling, clearly not.

Chu knew clearly that the rotation angle of the rifling needs to be considered according to the weight, length and speed of the bullet, but how many riflings are needed, whether they are left-handed or right-handed, and how to engrave them into the inside of the barrel are all things that he can't figure out.

The reason why he thought of the flintlock rifle was because with the number of people in his family, even if you count the three religions that Xiaobao knew, it was just a group of infantry, and the weapons were not neat, not all in one hand.

So far, only Xiaobao and Chu Qing's more than 50 guards can have standard weapons.

Chu Qing had seen the fight between the Salt Gang and the Beggar Gang, and the weapons in their hands were also very messy, mostly axes and hatchets, but there were quite a few people. Thousands of people participated in the gang fight.

If you count all these people, you will find that there are no long-range attack troops.

If Chu Qing knew that Xiaobao and Lao Yu were secretly building a cavalry team, he might be able to feel a little comfort, but even if there was, bows and arrows as long-range weapons were not easy to equip.

So when there are not many iron ingots, it is very cost-effective to produce a weapon such as a flintlock rifle that can be used with a little training.

Xiaobao was still waiting anxiously for Chu Qing to reply, Chu Qing knew that he wanted a positive answer, but he could only say: "I'll discuss it with your Grandpa Lu later, it's too much."

Little Treasure's eyes were slightly disappointed, so Chu Qing had no choice but to return a troubled smile: "If I had known there would be a day of time travel, I would have studied hard and read more science and engineering books."

Xiaobao couldn't bear to make his mother unhappy during the New Year, so he comforted: "Mom, you are good enough. If Dad comes, he is a liberal arts student, so there is nothing wrong with him?"

To this, Chu Qing objected: "It would be great if your father came, and go directly to the imperial examination! Our mother and I don't have to bother!"

After thinking about it, it was wrong: "Bah, bah, bah, bah, bah, bah, bah, bah, bah, bah, bah, bah!"

Xiao Bao scratched the back of his head, folded his hands obediently and worshiped the sky: "Bah, bah, oh my god, you just pretended I farted, and you didn't hear anything!"
