Seeing Xia Yuan's release, Zhu Houzhao shook his head secretly, what does it mean to put it like this, it seems that the master's attainments in artillery battles are far inferior to this palace.

Thinking to himself, he squatted down at the gate of the courtyard, made a small hole in the snow on the ground with his fingers, stuffed the firecracker in, and covered it with snow, leaving only a short lead outside.

Then the lit incense was brought close to the lead, and with a snort, the lead was ignited, Zhu Houzhao turned his head and ran, bang, firecrackers exploded, and snowflakes splashed.

"Haha, master, have you seen it, how is my cannon?"

"Very good, good Raines."

Xia Yuan nodded perfunctorily, buried the cannon in the snow, lit it, turned around, and acted in one go.

Bang!

There was another crunching sound, snow slag splashing and white smoke wafting out, emitting a wonderful smell of sulfur.

At this time, many passers-by stopped, those hired workers who helped to load New Year's goods, and the entourage brought by Zhu Houzhao, all eyes from all over the world were focused here, all watching them set off the cannonball.

Xia Yuan's mood unconsciously became happy, and the more onlookers, the happier he was when the cannon battle was released.

Another cannon was lit and thrown out, Xia Yuan got up and took a few steps back, glanced at Zhao Yuerong and noticed Zhao Yuerong, Xiao Chuzi ran out at some point, and was standing at the gate of the courtyard and watching.

At this time, her little face was flushed, she was breathing, and her big eyes were staring at the lit cannon without blinking, her expression was a little worried, but there was a little excitement in her melancholy.

There was a bang, a firecracker exploded, and her eyes lit up visibly.

Taking in this scene, Xia Yuan smiled secretly, walked over and asked, "Do you want to put one in the little camellia?" ”

Hearing this, Zhao Yuerong was a little moved, but after hesitating, she still shook her head, "I don't dare." ”

"Also, what kind of cannon does the girl's family fire, how dangerous it is, you should be an onlooker and watch your husband put it on you."

The whole cannon battle with a whip was completed by the two of them in various ways, and they basically tried all the methods of firing guns that they could think of and could do at present.

Dig a pit, detain a container, stuff it into a hole in a wall or a snowdrift, and keep a program, break the firecracker, pour out the gunpowder inside, and release the flowers.

After playing a game, Xia Yuan suddenly felt a little boring, the reason is that the power of this firecracker is too small, and the strength is not big enough, such as deducting a teacup on the top, just a muffled sound, but the teacup does not move much.

There were no cans in the Ming Dynasty, so this teacup replaced the role of cans, as we all know, stuffing a cannon under the can, if the can is not blown up, it is soulless.

"Don't play, don't play, I'll go back to the yard to finish building the snow lions, and then go back to my hometown for the New Year."

Xia Yuan felt bored, and was ready to get rid of the snow lion, and then took his daughter-in-law back to his hometown for the New Year, but Zhu Houzhao felt that he was still unsatisfied, not to mention that he had now recognized Xia Yuan's attainments in firing artillery, and the master was also a person who could play.

So he hurriedly persuaded: "Master, don't go, I haven't had enough fun." ”

"This firecracker is too powerful, it's not fun to play, you can play it yourself."

"Shall we set off fireworks?"

"What's the point of setting off fireworks in broad daylight?"

"Master, don't you think firecrackers are too powerful? I have a way to make firecrackers more powerful. ”

Xia Yuan paused, then turned back again, "Say it and listen to it." ”

Speaking of this, Zhu Houzhao obviously got momentum, and immediately danced with his eyebrows; "This method is something I figured out myself, get out all the gunpowder in a whole firecracker, and then wrap it together to make a big cannon again, it's so powerful that I don't usually dare to play like this in the palace."

Xia Yuan thought that this thing had figured out some way, but after listening to him, he was disappointed, that's it?

In his previous life, he would have played like this when he wore open crotch pants.

However, he still changed his mind, "Okay, let's see the division make a cannon battle for you." ”

"The master can also make his own cannons?"

Xia Yuan rolled his eyes, "How fresh, this thing has no technical content at all, and it's not like I'm blowing it to you, the artillery battles I made are definitely much more powerful than the ones you did before." ”

Zhu Houzhao said in a sullen voice: "I have used at most one whip of gunpowder before, if the master you use the gunpowder of two whips, the artillery battle you make will definitely be more powerful than what I do." ”

The more gunpowder is used, the more powerful it is, and fools understand this truth, but Xia Yuan said that the young man was too naïve, and he wanted to make the power of the cannon battle bigger, not only because of the increase in quantity, but also because of the progress of the production process.

When he put the flowers before, he found one thing, the ratio of this gunpowder was wrong, and there was obviously a lot of sulfur and charcoal, especially charcoal, which was ridiculously large.

The price of charcoal skyrocketed in winter, and those craftsmen even put so many firecrackers, which were worthy of being made for the emperor, and they really didn't care about the cost.

Of course, it may also be that the craftsmen of this era did not figure out the correct proportions of gunpowder.

One nitrate, two sulfur and three charcoal.

This recipe for the ratio of black powder is catchy, but many people don't figure it out, and one, two, and three here are not a unit of measurement at all.

Not to mention that it should be deployed in a ratio of one to two to three.

The correct meaning is one pound of potassium nitrate, two taels of sulfur, and three taels of charcoal, and the proportion of potassium nitrate must reach at least 75 percent.

But according to Xia Yuan's visual measurements, potassium nitrate accounts for half of these gunpowders, while sulfur accounts for 20%, and charcoal accounts for 30%.

The ratio is not right, the power of this firecracker can be so big that it will be a hell of a thing.

In response to this problem, Xia Yuan could only break the firecracker, pour out the gunpowder inside, and then pick up a small wooden stick and pull out the extra sulfur and charcoal in the gunpowder.

Zhu Houzhao squatted next to him and yawned, he didn't know what Xia Yuan was doing, he felt tired and panicked when he looked at it.

Xia Yuan was even more tired, and this was still a delicate job, after only dialing a few, he lost his patience, turned his head to Gu Dayong and greeted: "Who, please go and bring the fireworks, I will use the gunpowder in there for artillery battles." ”

Hearing this, Zhu Houzhao seemed to be a little shocked, "How can the gunpowder in the fireworks be used for artillery combat?" ”

Xia Yuan seemed even more shocked, "Why can't the gunpowder in the fireworks be used for artillery battles?" ”

"The cannon battle is bang! The fireworks are flying into the sky and banging., different. Zhu Houzhao said and gestured, raised his arms together and raised them high above his head, and then unfolded them, making a gesture of hugging the sun, and his mouth also emitted inexplicable onomatopoeia.

Xia Yuan completely understood the meaning of this product, and asked rhetorically after following his appearance: "Then do you know why the fireworks are bang. Wow, and the artillery battle is just a bang? ”

"Why?"

"Because one is sealed and the other is not sealed, but it is the same gunpowder, which means that if you plug the muzzle of the firework tightly, it will just bang, and it won't fly into the sky and bang. Wow. Do you understand? ”

"Is that so?"

Zhu Houzhao was a little incredulous, and his eyes were full of confusion about knowledge.

At this time, Gu Dayong brought over a box of fireworks, and Xia Yuan ignored the somewhat stupid His Royal Highness the Prince, took the fireworks, poured out the gunpowder inside, and then pulled it a few times with his hand.

Obviously, the ratio of gunpowder in this is also wrong, and the gunpowder contained in it is much more than in a small firecracker, so it is more intuitive to see.

Potassium nitrate is indeed only 50 percent, sulfur 20 percent, charcoal 3 percent.

This time, Xia Yuan didn't take the little stick and pull it slowly, and set out the excess charcoal and sulfur, but asked the following question: "Where is the potassium nitrate sold?" ”

"Xiao Xiao acid nails?" Zhu Houzhao was a little confused.

"Oh, that's it. I mean saltpeter after purification. ”

Gu Dayong understood the meaning, leaned over and said, "What Master Xia said is fire and fire?" ”

"Yes, yes, yes."

"If Master Xia wants to buy nitrate, it's not easy to buy, but there are a lot of them in Wang Gong's factory."

Wang Gong factory?

Xia Yuan's brain twitched, and he blurted out, "The one that exploded?" ”

“？”
