The black powder of this era, or the black powder of the entire ancient era, has a very serious problem of combustion efficiency, because after all, it is a mixture of three powders, and it is impossible to achieve complete fusion of proportions, and it is impossible to play full combustion.

In addition to the burning problem of black powder itself, it is not very stable when transporting, storing and fighting. In the terrible road conditions of the Middle Ages, even if the storm carriage had the best shock absorption system in the world, the gunpowder in the powder keg would still be constantly bumping.

The density of each gunpowder material is not the same, for example, charcoal powder is the lightest of the three, so it will move up relatively when transporting, while sulfur and saltpeter will dive, after a long time of bumpy movement, there will be a situation of layering up and down the raw materials, and the powder of the upper and lower parts of the same barrel of gunpowder will have a clear difference in the bullet force, so the early gunpowder needs to be exported and remixed before it is officially used, otherwise it may not be able to hit.

In addition to the delamination during transportation, how to prevent gunpowder from moisture is also an important issue, which does not mean that the gunpowder is directly exposed to rain or water sources. It is because the saltpeter and charcoal in the gunpowder formula itself has strong water-absorbing characteristics, as long as the humidity in the air is large, it is very likely to be damp and cause the gunpowder to agglomerate, so there is naturally no way to use such gunpowder.

Moreover, even if the gunpowder is poured out to dry, the dust of the gunpowder will fill the air, which will very likely lead to a fire or explosion. This is like the explosion of some dust in a flour mill and so on, as long as the density of dust in the air reaches a certain amount, it will simply turn the entire space into a powder keg, which is why the discipline requirements in the musket factory are the highest in the entire Storm Castle factory, and even alcohol is strictly forbidden and so on.

It is because there are too many possible problems with gunpowder, so the flint will be very worried, whether the appearance of the lord is a crime of Xingshi, he really can't think of anything else.

"Flint, don't worry, I just want to talk to you about gunpowder. Is there a quieter room here, I'd like to have a good chat with you. ”

Duke said this as gently as he could, intending to find a space to enclose the point. Because what he is going to say to Flint next may be related to the future improvement method and direction of gunpowder, even in the modern country, it is one of the top secrets of the state, and Duke naturally wants to prevent the leakage of the secret recipe of gunpowder.

Although these dwarven craftsmen have nothing to say at the moment, it is impossible to guarantee absolute loyalty to all people in this world. Even if he was very loyal, it was impossible to guarantee his family or friends, or coercion and inducement, so Duke still chose to speak secretly.

"My lord, in front of me is my office, where you can talk quietly. ”

Flint didn't realize Duke's secrecy, he simply thought that Duke wanted to know a quiet space to speak, after all, in the powder shop, the noise of all kinds of grinding would also be affected. Another point is that black powder is actually not a secret in this world, basically there are records in the royal library of any country, but the human kingdom can't look at these things, even if they know, they have never been put in their eyes.

Coming to Flint's office, this is not a standard office, more like a laboratory, it seems that Flint is not resting on his laurels, just thinking about the current power of gunpowder is enough, he must also be experimenting with the effects and power differences brought by various formulas.

So when he saw this scene, Duke was very happy, after all, he was weak in the hands-on formula of gunpowder, even if he knew the principle, he needed a hands-on person to help Duke complete the experimental steps. Therefore, the completely different way flint and stove treat gunpowder is that Duke needs to find a gunpowder expert, not a simple gunpowder worker!

"Flint, my main purpose in approaching you this time is to find a way to improve the current power of gunpowder. You also know that now the rifling of the Storm Gun has appeared, which has greatly improved the range accuracy, and more importantly, the Storm Gun has now begun to be produced and developed, and the demand for gunpowder and power are greater. ”

"The current black powder, both in terms of power and storage, is actually not very convenient, and it cannot meet some of the needs of the Storm Army's future operations. So I want to improve the black powder, or make another more powerful gunpowder to meet the needs of the Storm Army in the future, what are your suggestions for this idea?"

Hearing Duke say this, Flint's face was simply full of surprise, because he didn't expect that Lord Lord actually had the same idea as himself, that is, he was not satisfied with the current power and storage and transportation of black powder, and wanted to improve all this. You must know that not to mention the human lords, even the dwarves have been rare for thousands of years, and Flint can't believe that Duke would say such a thing.

"Lord Lord, I'm so excited, because this is the first time since I have been engaged in gunpowder research, someone has told me to improve the current black powder, they are all satisfied with the current gunpowder power and production, you are the real wise man, you see the future vision!"

In the face of Flint's heartfelt praise, Duke was a little embarrassed, the reason is actually very simple, that is, Duke did see the future, but this was not because of how far-sighted he was, but because Duke himself came from the future, how could he not see the development of gunpowder in the future?

So Duke said with a rare blush: "Flint, do you have any discoveries or achievements now?"

Duke asked rhetorically, wondering if the flint had already produced some results that might be able to supplement his own approach.

"Tell my lord, I have been experimenting with the ratio of gunpowder to these people, such as how much saltpeter should be used in artillery, how many stones should be fried, and how many muskets should be used. At present, I already have the most suitable ratio of musket gunpowder, which can make the gun's discharging speed by 10%, increase the power of the musket by 15%, and have a certain chance of penetrating the iron armor at a distance of 100 meters. ”

"Very nice. Duke nodded, the fifteen percent increase in power was already a significant increase, but Duke's purpose for coming this time was not just that, he had a way to increase one hundred percent!
