Black powder, the formula mainly includes saltpeter, sulfur and charcoal, which is made by manual mixing and refining after reasonable proportioning.

The power of black powder is closely related to the ratio of the three substances.

Gunpowder is one of the four great inventions of the Chinese nation, black powder is a major contribution of the Han people to the world, since the invention of the late Tang Dynasty, to the maturity of the Song Dynasty after hundreds of years of experiments and practice, the proportion of black powder has become customized.

However, at this time, the ratio of gunpowder was not the so-called one nitrate, two sulfur and three charcoal, but saltpeter accounted for 80 percent, sulfur and charcoal each accounted for 10 percent.

In fact, after many experiments in later generations, the optimal ratio of modern black powder is 75% saltpeter, 10% sulfur, and 15% charcoal.

"My lord, I have some research on gunpowder, and we have a special gunpowder production workshop in our ordnance institute, so you can take your adult to see it!"

Song Yingxing was very modest, after all, the formula of gunpowder had long been solidified, and most of the craftsmen who had studied military affairs understood it.

The gunpowder workshop was built in the southwest corner of the entire armory, with a large wasteland outside the walls.

Although the production of gunpowder has been strictly processed, it is still far away from the Minzhuang settlement in the southeast for safety reasons.

The gunpowder workshop was not very large, only a dozen craftsmen were busy with something similar to masks, and the room was filled with the foul smell of saltpeter.

The craftsmen saw that the second gear head and the big gear head were here together, and they were a little cramped for a while.

"Don't be nervous, you're busy with yours, this official is here to see!"

Seeing that a few craftsmen who were dispensing gunpowder were in a panic, they actually scattered a bucket of black things on the ground, which gradually startled Liu Hong.

This is especially black powder, can you kid use dim sum, this official doesn't want to explain here.

Liu Hong gradually walked to the stove where the three substances were mixed, and stopped him when he saw that the craftsman was weighing each of the three substances with a weighing rod.

"Give the official one tael of sulfur, one tael of charcoal, and seven taels of saltpeter, mixed." Liu Hong gradually said to the craftsman who weighed him.

The craftsman naturally didn't dare to slack off, and immediately started weighing again, and after waiting for about half an hour, the black powder that Liu Hongjian wanted had been configured.

Liu Hong gradually took out two large porcelain bowls, took out about one or two from the original black powder, and took out the same amount from the newly configured black powder.

Song Yingxing didn't know why Liu Hongjian changed the proportion of black powder without permission, after all, the formula ratio of gunpowder had already been customized, and if there was a more suitable ratio, the ancestors would have proposed it a long time ago.

The two walked to the open space outside the gunpowder workshop and placed the two bowls on a stone bench.

Liu Hongjian played with ancient black powder for the first time, he was a little nervous, he held a lighter in his right hand, afraid of being burned, and found a long wooden stick.

He lit the stick with a lighter, and slowly poked his right hand into the original ratio of black powder.

Hearing a bang, the porcelain bowl containing black gunpowder erupted into a burst of strong light, and at the same time, a thick smoke filled the surroundings, and the bottom of the porcelain bowl was smoked black.

Liu Hong shook his head, and then poked the wooden stick at the black powder that had just been configured.

There was another bang, and the new ratio of black powder produced a bigger fire than just now, and there was even a bang in the smoke.

"Oops! I'm the second Olympics" Liu Hong gradually covered his arms and shouted, startling Song Yingxing on the side.

It turned out that the new configuration of black powder was too powerful, and it directly shattered the large porcelain bowl, and a piece of porcelain directly scratched Liu Hongji's left arm.

"Your Excellency, are you alright?" Song Yingxing couldn't help but sigh at the power of the new black powder, and hurriedly walked to Liu Hongji's side.

Fortunately, it was only a skin injury, and his arm was slightly bleeding, Liu Hong gradually took out Yunnan Baiyao from the ring, sprinkled some on it, and asked Uncle Song to help wrap a little gauze.

"Your Excellency even carries healing items with you!" Song Yingxing helped Liu Honggradually treat his wounds, and said strangely.

"This official also has the name of a miracle doctor, habits, habits!" Liu Hong gradually snorted, he can't say that he has a storage space!

"Where did you get this proportioning method, looking down, this new recipe is more than twice as powerful as the original gunpowder, you see this porcelain bowl, it has been blasted to pieces.

If this is loaded into the chamber or breech, it will definitely increase the range a lot, which is a miracle, it seems that I am still too ignorant below! Song Yingxing sighed from the bottom of his heart.

There is no extreme and absolute in the road of scientific research, this is a never-ending road, what we have to do is to constantly break our original judgments and make them closer to the end.

"Ha, this is also what the official himself pondered at home the day before yesterday, a small matter, a small matter, not enough to worry about!" Liu Hong gradually became modest.

You can't say you have a plug-in, right?

The more humble Liu Hong became, the more Song Yingxing felt that the young man in front of him was unfathomable.

Is this still a trifle? If this new type of gunpowder had been made earlier, the firing range of the cannon would have been at least doubled, if not to mention anything else.

What does this mean? It means that the two armies are fighting, and when the opponent's artillery is not yet within range, our artillery can overturn the opponent's defenses!

"Old Song, in addition to this new formula, this time the official has a task for you." Before he felt anything, Liu Hong gradually felt a hot pain in his arm.

"What's the matter, my lord? I make up my mind to do my best for adults. The two returned to the hall in the middle of the armory.

"Look at this thing, can we make it in our workshop?" Liu Hong grinned and took out a drawing from his waist.

It reads 'Paper Shell Bullet' illustration on it.

"Paper bullets?" The illustration shows that although it is a simplified character, except for some rare characters, the text of the late Ming Dynasty is not much different from that of later generations.

Song Yingxing read the instructions carefully, sometimes frowning, and sometimes looking suddenly realized.

"My lord, according to the understanding below, this is a fixed device made of projectiles and gunpowder, and it is packed in a paper tube, well, this is a novel usage, I think it can increase the loading speed of soldiers!"

Now Song Yingxing no longer asks why, because the surprise given to him by the young man in front of him has made him numb.

He guessed that Hou Ye was either guided by a master, or he was born a god.

Otherwise, no one can explain, why is he the same person, why is Hou Ye so good?

In fact, the paper shell device that Liu Hongjian gave to Uncle Song was the final version, and when the Europeans first put it into use, they only used a paper tube to stabilize the gunpowder, and the projectile had to be manually pressed into the chamber of the gun.

This method was used for decades, and then I don't know who had the whim to put the projectile in it.

Sometimes it's so weird in research, and when you make something, it doesn't feel like that.

But why couldn't I think of it at the time?
