When Chan came down to inspect the gunpowder factory, Mai got an unexpected surprise...

"Is this granulated gunpowder?"

Yes, what was placed in front of Wang Dou was no longer the powdered black powder, but the formation of small granules, uniform in size, like tiny black pearls.

With this granular black powder II, Wang Dou's fire rao soldiers can use less gunpowder than now, but the range and power of the fire system is greatly improved, and the estimated effective lethality is nearly 100 steps. Can be compared to the original old-fashioned bird lock. Much more than the smoothbore guns used by Western armies in the form of granular black powder in the contemporaneous period.

The reason why Daming's fire prosper hits far and accurately is that in addition to sparing the body, there is a light door in the back, plus the front sight. Form a three-point-one-line aiming advantage. The fire of the West. Until the beginning of the nineteenth century, except for a small front sight, there was not even a light door behind the lock, so how to hit far and accurately?

Lin Daofu, Li Maosen, and the surrounding craftsmen all looked at Li Zhifen with envy, just turning the gunpowder from powder to granular, he had to be so praised by the Lord of Ethics, it seemed that he had unlimited prospects. Li Zhifen didn't expect that he had inadvertently achieved a research result, and he didn't know what the prospect was. But the adults of ethics have more confidence than themselves, so they have to sigh that they have met the Lord, know the grace of the encounter, and forget the last tooth.

A smile bloomed on his round face, and when Wang Dou asked him to produce this granular black powder in large quantities, he respectfully accepted the order, but then he remembered something: "My lord, if the gunpowder factory wants to produce this granular gunpowder in large quantities, it needs a lot of sulfur. This matter still needs to be worried about by adults. Wang Dou nodded, the formula of black powder is nothing more than saltpeter, sulfur, charcoal, the army makes black powder, no matter where it is, the source of charcoal is always not worried, there is a place for Shunxiang Fort to collect nitrate. The source of the nitrate in Wang Dou's army is also not a problem.

However, the sulfur component in it, although the proportion is not large, is very important. In black powder, sulfur is a binder that can mix the three components evenly, and only black powder containing sulfur can be made into granular black powder of almost the same size. In this place of Baoanzhou, Wang Dou did not know whether there were sulfur minerals, and with the increase in the use of firearms in the future, obtaining a stable source of sulfur was also a big problem.

He buried his thoughts in his heart, and just said: "You don't have to worry about this matter, this official will solve it." You can make a child medicine with peace of mind. ”

A few days later, after the operation of Wang Dou and Li Maosen. Lai Yuanlong, the ambassador of the Security and Guard Ordnance Bureau, came to Baoan Zhou City, and this Lai Yuanlong was about forty years old. ”

Wang Dou was in a very happy mood, the two major problems were expected to be solved, it seemed that the role of talents was really extraordinary, and he asked another question.

Lai Yuanlong: "Lu Mirao? I didn't expect adults to know about it. Speaking of which, Xia Guan once went to the Ordnance Bureau of the Ministry of Industry, and was fortunate to see the real objects and systems of Na Lu Mirao. ”

He shook his head again and again: "I want to make this thing." Hard, very hard. ”

Relying on what Yuan Long said, Na Lu Mi Rao was actually very rarely used in the Ming army, mainly because it was extremely difficult to fight and the cost was too high. The all-metal structure of Lumi Town, the body is heavier, it is a small caliber, the range of the excellent Lumi Rao can be one hundred and fifty steps, and the initial height of the projectile is basically the same as that of the rifles of later generations. It was the firearm used by the Qing army in the Opium War in later generations, and it may not be stronger than Lu Mirui in terms of performance.

Its essence lies in the double-layer milling pipe, the pipe body is integrated, there is no number of segments, and the internal and external pipes are connected in the opposite direction, and the safety is excellent. However, the manufacturing method is extremely complex, relying on what Yuan Long said, just the two can be closely intertwined to control the production and polishing. You need an old technician who has been in the art for decades.

In particular, the final casing is almost a strong drill, and a rather complex and sophisticated machine is required. The machine was intricately crafted, almost two people high. Only this kind of complex machine can ensure that the axial direction of the two rao tubes is consistent, and then slowly drill into it little by little.

In short, it is very painstaking and laborious to make Lumi locks. The requirements of each method are very high, and Wang Dou frowned when he heard it.

According to what Lai Yuanlong said, with his current technical reserves. Even if the Lumi system is developed, what is the point if it cannot be mass-produced? Maybe when the time comes, I will make some small batches in the future. Give it to the elite troops and let them use it as snipers.

Thinking of this, Wang Dou suddenly remembered the rifled guns of later generations, and he told Lai Yuanlong what he knew, Lai Yuanlong thought for a long time, and finally said: "My lord, this rifled fire system is actually the same as Lu Midi, and Xia Guan may be able to develop it, but if you want to make it in large quantities, I'm afraid it will be difficult ()." ”

Jidou smiled and said, "This official knows it in his heart. Ambassador Lai will go to Shunxiang Fort first, where the defense officer, Lord Lin Daofu, will arrange everything for you, and you will first develop Zisheng Fu Rao and Huomen Zeng, and wait for these two to be successful. Let's consider Lu Mirao and rifled fire. ”

Soon, Lai Yuanlong came to Shunxiang Fort. In Shunxiang Baojing Machinery Factory, Lai Yuanlong has a spacious and bright studio, and there are many raw materials for him to dispose of, and there are no mundane worries. Without the elbow of the officials, without the yang and yin of his colleagues, and the intrigue, Lai Yuanlong only felt that his whole body was full of infinite strength.

There was a "boom", and a stout wild boar was knocked over on the woods on the sunny slope. Several of the fire soldiers of the general A team surrounded him with a grin, this guy is fast, clever and fierce, if everyone is not a small person who wants to knock down this wild boar, it is not an easy task.

When they approached, everyone saw that the wild boar had a strong body, a straight mane, and exposed fangs, and they were afraid that it would weigh hundreds of pounds.

One of the firelock soldiers said excitedly, "Good fellow. With such a big boar, we can have a good tooth sacrifice tonight. ”

Several of them happily carried the wild boar away. As they descended the mountain, they also met the brothers in the team from time to time. Everyone is carrying river rats, rabbits, pheasants, yellow sheep and other things, and it seems that everyone has gained more than seeing the wild boars carried by these people. Everyone was still surprised, and they all praised: "Good guy, such a big boar is really rare." ”

Everyone came to the bottom of the mountain freely, gathered into a team, and checked the harvest of the whole team, everyone was smiling, it seems that the brothers did not harvest these prey, not only these Wu brothers stationed in the silver mine can eat meat, but the miners in Shangjinggou can also eat big fish and meat these days.

The sergeants of the Cheng General A team laughed and laughed, along the large Pingchuan of the Wofosi Township and the Black Mountain Temple Township in the later generations. Just head northeast. In later generations, these places were densely populated, and then at this time they were still a wasteland, quietly uninhabited.

Old White Bull: There is another chapter in the evening.
