Now the efficiency of the large-scale manufacturing of bows and crossbows and cold weapons in the Ming Dynasty is four or five times that of before, thanks to the improvement of production technology brought about by the advancement of steelmaking technology.

Although the guns are still made by hammering and molding, because of the assembly line production and the improvement of metal materials, the guns of the Ming Dynasty still rank first in the world, beating the current Manchu Qing Dynasty.

In addition, there is an even more impressive technology: the continuous improvement of the firing mechanism of the flintlock pistol.

He is now specialising in this area.

Now the best main battle musket of the Ming Dynasty has progressed from the Chongzhen 17-type flintlock pistol to the Chongzhen 19-type flintlock pistol.

The biggest difference of the Chongzhen 19 flintlock pistol is the improvement of the barrel material and shape, the hexagonal shape makes the barrel have a simple or early analogue of the rifled gun.

In this way, it is undoubtedly that the rate of fire and range and even accuracy of the Chongzhen 19-type flintlock pistol are stronger than those of the Chongzhen 17-type, and it is no longer a problem to effectively shoot the enemy within 200 steps.

But what Zhu Youzhen didn't expect was that Bi Maokang had already designed another new gun.

And this new gun can be said to be a real epoch-making killer in the field of Daming flintlock pistol manufacturing!

Because this new musket has not been improved into a rifled gun.

(Why it has not been described in the previous chapter, I will not repeat it here)

But this new musket has been greatly improved in terms of reloading, because it is a rear-loading gun, that is, two rounds of bullets at the rear end of the gun.

This firearm was originally invented by a man named Dai Zi during the Kangxi reign of the Manchu Qing Dynasty.

Now under Zhu Youjian's point, Bi Maokang directly let it be launched in advance.

"As Your Majesty has mentioned, there are two rounds of bullets in it, a total of twenty-eight bullets, and when the first trigger is pulled, gunpowder and lead bullets can fall into the cartridge automatically;

The second round then turns, and the flint is fired;

After the first round, the second round can be played;

This saves reload time and improves reloading efficiency, and the burst ability is greatly enhanced, and on the basis of Chongzhen 19 style, it can make its range and accuracy higher, plus according to the requirements of His Majesty, the three-point and one-line aiming and shooting method can also improve the user's shooting accuracy. ”

After Bi Maokang said this, Zhu Youzhen nodded: "When will this plan be put into production?" ”

"It is expected to be January next year, it is still in the experimental stage, some parts have not been standardized, and there is no way to implement grinding machine processing, and some precision places still need skilled craftsmen to polish, but this gun is indeed much better than Chongzhen 19 style, Weichen means to speed up the production progress while focusing and training more skilled craftsmen to create a batch of non-absolute standardization trial use on the battlefield this time;

Actual combat is also the best way to test firearms, if it were not for the Chongzhen 17th style in the development and production of the war soon after, we would not have been able to improve the Chongzhen 19 style so early. ”

Bi Maokang's opinion, Zhu Youzhen agreed very much, so he asked Bi Maokang to first build a batch to equip a co-ordination of 1,000 people.

"This kind of gun will be named Chongzhen 21 flintlock pistol at that time, so is there anything else that can be improved, such as whether this firing device can also be improved;

The current firing method is to ignite the gunpowder by generating sparks from the flint, but many times the flint will fail or the strength is not enough, resulting in the need to hit several more times, which delays the shooting time, which is very fatal on the battlefield, and the cost of flint is too high;

We can find out if there is a flammable material that can be used to ignite the gunpowder instead of flint, such as paper or better, and ignite the gunpowder directly by hammer impact. ”

Zhu Youzhen is talking about the firing gun, while Bi Maokang is a little embarrassed:

"Your Majesty's meaning, Weichen understands, but what Your Majesty said about this kind of gun paper is not very good, easy to get wet, I have a rainy south of the Ming Dynasty and now the climate is cold, Weichen is thinking about whether there are better materials, these days have also tried a lot such as oilcloth, but in the end there is still no way to replace flint."

"This requires you to create your own substance, I remember that there is a material that can, this is called mercury thunderate, which is coated on the copper plate as a hammer, and then collides with a sharp structure, it will directly ignite the gunpowder, this kind of thunder mercury is mercury thunderate, mercury, presumably Ai Qing already knows what it is, as for thunder acid, it may be a little difficult for you, and after this war is over, I will personally help you how to extract thunder acid and make mercury thunderate."

This can indeed only be taught by Zhu Youzhen himself at that time, and Zhu Youzhen himself has to remember it well.

Daming can now produce some natural products and rough processed products such as alum, alum, fire salt, salt, sulfur, quicklime, trona, ferrochrome, mercury, plant ash, etc.

However, mercury thunderate still needs further experimental and technological breakthroughs for Daming.

It may not be difficult for modern times, but for the era of the Ming Dynasty, people don't even know what a thunder root is.

But it's not without the possibility that it can't be realized.

Because first of all, the easiest way is to make use of the silver mirror reaction.

After the silver mirror reaction for a long time, the organic acid of thunder acid will be produced, and then the mercury oxide reaction can produce mercury thunderate, and the silver mirror reaction uses silver nitrate and aldehyde group reduction to produce silver reaction, this experiment is not difficult, Zhu Youjian can operate.

Daming can now use sulfuric acid and fire nitrate to produce nitric acid, and then there is no difficulty in producing silver nitrate.

Aldehydes can be found from glucose, and glucose is a monosaccharide, most of the sugars in our lives are polysaccharides, of course, it is not without glucose, such as blood and some fruit juices, but the amount is too small.

In order to obtain glucose on a large scale from an industrial point of view, a certain concentration of dilute hydrochloric acid is required to extract from starch, which naturally comes from potatoes.

However, Zhu Youzhen does not plan to use the silver mirror reaction to produce thunder acid.

Because he didn't know how much thunder acid the silver mirror could put out for a long time when it reacted.

He decided to choose another method, that is, the reaction of silver nitrate and saturated ethanol solution to obtain thunder acid, and then react with mercury oxide to produce mercury thunderate, which is not difficult.

But Zhu Youzhen now has to teach Bi Maokang and other Ming people how to prepare the solution.

After all, whether it is the use of silver mirror reaction or the use of ethanol, it is necessary to prepare a solution, and this is actually the chemistry knowledge in middle school, but Bi Maokang and others do not know, they may not know the difference between solution and suspension at all.

Song Yingxing, because he was in charge of the Iron and Steel Smelting Bureau, made alloy steel, and obtained the alloy steel technology by calcining natural compounds at high temperatures.

Zhu Youzhen hopes that Bi Maokang can master the use of chemical reactions to extract and manufacture the compounds he needs, and perhaps mercury thunderate is just the beginning.

When it comes to mercury thunderate, we have to admit that it is a highly toxic substance.

Zhu Youzhen didn't plan to touch it himself, he felt that he needed to find a Western fan to operate at that time, and he would guide him from the side.

Once the mercury thunderate can be manufactured, the firing pistol can be manufactured.

In addition, Daming now has the technology of rear-loading guns, if it breaks through rifling manufacturing in the future, it can produce rear-loading rifled guns, and Daming may really be invincible in the world at that time.

Zhu Youzhen began to fantasize.

But in fact, now with the current gun industry of the Ming Dynasty, it is enough to be invincible in the world.

This is only technical production, as well as a complete set of industrial systems in the Ming Dynasty, and Zhu Youzhen still continues to inspect his military base.
