"Come, Brother Su." Mu Ying took out the contents of the box one by one, beckoned to Zhu Su and said, "Come and see, this is the gunpowder and firearms commonly used by my Ming army today." ”

"I'll see." Zhu Su walked into the courtyard and saw that there were three or four firearms of different appearances on the ground, as well as a box of gunpowder.

"This gunpowder ......" Zhu Su squatted down, twisted the powder of gunpowder and looked at it. I saw that the gunpowder particles were black and full, and they did not look like they had a bunch of impurities as they imagined. couldn't help but mutter: "Didn't you say that the gunpowder in Taqing is strange, and everything like cinnabar, lead, mercury and the like is added to it, and most of it is useless impurities?" Why is this gunpowder in the early Ming Dynasty so pure? ”

I thought that I could show off a wave of black powder ratio and pretend to be a Boyi. But this gunpowder, it doesn't seem to be too much of a problem?

"What's wrong?" Seeing that he was stunned, Zhu Biao asked.

"Nothing, huh. Let's take a little light and take a look. Zhu Su said.

Zhu Biao took a lamp (similar to a fire fold), divided the gunpowder with a piece of paper, and lit it far away. After only a few sounds, the gunpowder quickly burned clean. Zhu Su smelled it and looked at its ashes, and felt that there was nothing wrong with it.

"Weird...... At the beginning of the Ming Dynasty, the ratio of gunpowder was already so close to black powder? Zhu Su was a little shocked by the wisdom of the ancients.

"Then why is it that at the end of the Qing Dynasty, the quality of gunpowder was not as good as that at the beginning of the Ming Dynasty. In the battles of Grand Horn and Sha Jiao, the British army captured a powder magazine of Qing gunpowder, but sank them all into the sea with disgust, and called it 'a shoddy and useless thing'......"

What Zhu Su didn't know was that in fact, under the disdain of several generations of ancestors, by the time of the Yuan Dynasty, the ratio of gunpowder had been refined to the extent that the ratio of saltpeter was sixty percent and sulfur charcoal was two percent each, which was very close to the optimal ratio of black powder.

In the Ming Dynasty, the ratio of gunpowder was further scientific, and the Ming people's exploration of gunpowder and firearms never stopped. In Qi Jiguang's "New Book of Discipline", the ratio of gunpowder is basically the same as the best ratio, and several breakthrough new types of firearms have appeared.

However, once Jiannu went south, barbarism replaced civilization. The process of firearms in Huaxia was cut off. His short-sighted sentence of "riding and archery is the foundation", and the development of firearms has directly regressed by a hundred years, and it is even inferior to the Song Dynasty.

Coupled with the shortage of basic science and the shoddy craftsmanship of craftsmen, the gunpowder of the Qing Dynasty only rotted into Zhu Su's impression after a few hundred years.

And the gunpowder of the Ming Dynasty at this time was the pinnacle of Chinese gunpowder in the feudal era.

"This gunpowder...... Nothing seems to be a problem. Zhu Su coughed and said. I originally wanted to pretend to be a boy, but I didn't expect to be slapped in the face by the wisdom of the ancestors.

He thought about it for a while, but still proposed a small improvement plan: "If the gunpowder powder is wrapped in egg white, so that the powder is condensed into small round particles, this power can be further improved." ”

"Oh?" Zhu Biao asked, "Why is that?" ”

"Because granular gunpowder can increase the gap for air to enter, it can better promote the combustion efficiency of gunpowder." Zhu Su explained.

Zhu Biao asked suddenly, but he didn't expect Zhu Su to explain casually.

It seems that this knowledge is not casual nonsense, but it is true. Zhu Biaoxin said.

"Well, it's a bit of a hassle, but you can give it a try." Mu Ying groaned. If you can increase the power, you can break through an extra layer of heavy armor.

"As for these guns...... "Looking at this pile of stupid black and thick things, these Raushs look quite like burning sticks, maces, weighted versions of suona and the like, but they don't look like muskets. Zhu Su was a little at a loss.

"That, Brother Ying, why don't you shoot me and my eldest brother a few times?"

"Okay." Mu Ying did not shirk. The courtyard on the left and right is also big, and there is nothing big going on. He looked left and right, and pointed to a big tree next to the wall: "Your Royal Highness the Prince, I'll use that tree as a target, okay?" ”

"It doesn't matter. Brother please do it yourself. Zhu Biao said. It's just a tree with a crooked neck, and if it's broken, it's just a transplant.

Mu Ying nodded, picked up a "burning stick" and began to prepare. I thought that Mu Ying was going to show him a wave of accurate marksmanship, but he didn't expect him to carry a "burning stick" and go straight to a place only ten steps away from the crooked neck tree.

"Hey, is it so close?" Zhu Su thought suspiciously.

Then, Mu Ying began to clear the chamber, charge, compact, load, load, fit, and ignite, step by step, Zhu Su almost didn't fall asleep. It wasn't until there was a loud "bang" that the sawdust on the tree exploded that Zhu Su suddenly came back to his senses in fright.

"This is the most common 'Hongwu Gong' in my Ming Army. Its power, even if the Northern Yuan heavy armored cavalry attacked head-on, it could also be shattered with one shot. What does Brother Su think? Mu Ying said.

"Hmm. The power is acceptable. Just, does it have to be that close? Zhu Su asked Mu Yingdao.

"If it's above the battle array, it doesn't have to be so close. It's just that there is no accurate head in this thing, and the foolish brother is afraid that the courtyard wall will collapse, so he leans closer. Mu Ying explained.

By the way, the firecracker at this time was not rifled. Because the projectile will only fly around, the range is also very limited.

found a point of improvement, and Zhu Su's self-confidence came back a little.

"Do you need so many steps to shoot every time? How many times can you shoot during tea time? Zhu Su continued to ask.

"It's a lot of steps, but it's also necessary, and if you don't do it well, you run the risk of blowing up or dumb fire. Tea time...... I guess I can shoot four or five shots. It also has to be skillful and the barrel does not overheat. Mu Ying said.

"Hmm......" tea time, there were only four or five rounds, and the rate of fire was also slow...... The ancient fire gun he imagined would have to shoot two or three shots at least a minute, right?

I didn't expect it to be slower than I expected.

This rate of fire, if faced with cavalry, is absolutely useless even with a three-stage attack. To weave a tight network of fire that the cavalry could not pass through, it would take at least seventeen or eighteen strikes.

“…… It's too slow. Zhu Su couldn't help frowning.

"Brother Su can improve it?" Mu Ying said excitedly.

"Hmm......" Zhu Su touched the barrel of the gun, and only fired a shot, and the barrel was already slightly hot. If you want to make thorough improvements, you have to accumulate basic technology and improve from scratch in terms of materials. ”

"A quick fix...... I see that my brother you grasp the gunpowder, compact, ignite the fuse, and so on, step by step, it is very troublesome. ”

"Why not use a paper shell and put the gunpowder you need for each round into the shell. When using, tear open the paper shell and pour it directly into it. In this way, wouldn't it save time and effort? ”

As soon as these words came out, Mu Ying was suddenly stunned. Then he patted his knee: "I didn't expect such a simple method!" ”

"And so there is a bonus! The biggest difference between a sloppy hand and a skilled sergeant is that he grabs too much gunpowder or too little. In this way, it will either be dumb or explosive. ”

"With this method, wouldn't this big problem be solved? It's so simple, for hundreds of years, no one even thought of it! ”

"Big brother, don't be disappointed. Although the method of 'paper wrapped in gunpowder' is simple, it will take decades before it is figured out! Zhu Su smiled. Now, I'll take it out first to cheapen my Ming Dynasty. ”

"Brother Su, you traverser, you can really do miraculous feats!" Zhu Biao also smiled. Decades later, things are taken out in advance, doesn't that mean that I am a Ming dynasty and have been decades ahead of this way?

"What about the others? You just said what if you want to make a radical improvement? Mu Ying continued to ask.

"Well, let's improve the material first...... The guns made of this material are really not durable and tight. You need to train a more refined steel. ”

"This involves a lot of knowledge, and it is really difficult for me to do it alone. There must be a few people who understand science, step by step to carry out research, and many skilled craftsmen ...... say, "If you continue to do so, do you want me to engrave rifling wires and rub machine tools and blast furnaces with my bare hands?" Zhu Su smiled bitterly in embarrassment.

Zhu Biao and Mu Ying glanced at each other, and were about to say something, when a shrill voice from an internal supervisor came from outside: "His Royal Highness the Prince, His Royal Highness King Wu, General Mu, there is a little grandfather of the Duke of Wei Mansion who is visiting with a gift, and I invite His Royal Highness the Prince, His Royal Highness the King of Wu must meet and talk!" ”
