Li Yang, who was forced by He Zhang's cheap thunder to be scorched and tender, also had no choice but to reiterate clearly: "Its name has been decided, it is called firecrackers and firecrackers!" Can't you call it a yang whip, am I clear enough? ”

He Zhang nodded with admiration and praised: "My lord really regards fame and fortune as nothing, honor as dung, gunpowder, firecrackers and other inventions that are as famous as papermaking, but they can resolutely abandon it, this kind of indifferent realm of fame and fortune really makes his subordinates admire." Since the adults decided to give up naming this thing after themselves, the subordinates were disrespectful, and I decided to call it what medicine and chapter whip! ”

I'm chapter your sister!

You bitch, you're just brazen!

Li Yang was completely speechless, and said decisively: "Didn't you hear clearly, you are not allowed to call yang medicine and yang whip, let alone He medicine and chapter whip, you can only call gunpowder, firecrackers, and firecrackers, and you can't change a word." ”

"Aren't they all whips?" He Zhang, the slut, couldn't help pouting, and muttered unhappily.

However, seeing Li Yang's tough attitude, he also knew that the names of gunpowder and firecrackers could not be named by himself, so he turned to say: "My lord, how do you make these gunpowder and firecrackers?" ”

Li Yang said: "If you want to make gunpowder, you need three basic raw materials, saltpeter, charcoal, and sulfur. Then put it together in proportions to make gunpowder. ”

"Oh? It's that easy! ”

When He Zhang heard it, it turned out that the gunpowder that could be as famous as papermaking was so simple to make, it was just the ratio of three raw materials, and he couldn't help but be overjoyed: "Saltpeter, charcoal, and sulfur will be ready-made in the house, and the adults told me how to match the proportions, and my subordinates will order someone to mix hundreds of catties of gunpowder." ”

Li Yang thought to himself, you still don't know the characteristics of gunpowder at all, just prepare a few hundred catties, once it explodes, won't you all be blown up?

So he waved his hand and said: "Don't worry, this thing is a dangerous product, once ignited, it is very dangerous." ”

"Oh? Gunpowder is dangerous? ”

He Zhang finally became vigilant.

Li Yang nodded: "That's right, the power of gunpowder is huge, and after ignition, it will instantly release a huge amount of heat, resulting in an explosion." ”

"Explosion?"

He Zhang was stunned and puzzled: "My lord, what is an explosion?" ”

Li Yang said: "Well, if you get a few hundred catties of gunpowder, once it is ignited, your workshop will be flattened by the tension generated by the huge heat it releases." ”

"Huh? The entire workshop was razed to the ground! ”

At this moment, He Zhang became solemn and exclaimed: "The lethality is so huge, if it can be used in army combat, wouldn't it be even more powerful than the Qin crossbow?" ”

Li Yang glanced at him in surprise, thinking that this guy was really a talent, just by listening to the characteristics of gunpowder, he knew that it had great potential in the military.

At this moment, Li Yang really admired this slut. Although this is a bit cheeky, it ...... A piece of gold indeed.

You must know that although there were alchemists in China during the Warring States period who used saltpeter and other materials to make alchemy, strictly speaking, gunpowder was actually invented by Ge Hong of the Jin Dynasty. Moreover, China invented gunpowder, but in its long history, it was only used for firecrackers and fireworks, and it was really carried forward in the military.

And this He Zhang in front of him, according to the sentence that gunpowder will explode, immediately thought of its military use, this kind of vision, is very rare.

Li Yang nodded with satisfaction: "You are right, once gunpowder is used, it will definitely be able to replace today's weapons in the future, and it will even change the way the army fights, as well as the form of war." ”

Speaking of this, Li Yang, in order to better understand He Zhang, added: "It is no exaggeration to say that as long as you can use gunpowder to develop advanced thermal weapons, the Qin State can easily become the world hegemon and quickly dominate the Qin Ball, in short, the military potential of gunpowder is unlimited." ”

Li Yang didn't lie to him, gunpowder is a weapon of war, directly ending the era of cold weapons that has lasted for thousands of years!

When He Zhang heard Li Yang's words, his eyes were already shining, his face was flushed, his blood was boiling with excitement, and he hurriedly said, "Have you already thought of how to use gunpowder to make weapons?" ”

Li Yang nodded and said, "I do have some ideas, but ...... For now, let's prepare gunpowder first, make some firecrackers first, and how to use it and develop it into weapons will be discussed later. ”

He Zhang nodded: "Yes, after the invention of gunpowder, we will invent gunpowder weapons that can raze houses to the ground." ”

…………

On the same day, Li Yang personally went to the Jiangzuo Mansion to prepare gunpowder.

There was no shortage of saltpeter in the Shosaku Prefecture, because saltpeter had been used as medicine during the Warring States period. In particular, the alchemists attached great importance to saltpeter, saying that it was "born of the air of the sea and the salt, and it is the most divine thing of heaven and earth,...... It can make seventy-two petrified and turn into water, soften the hardware, and refine the eight stones, although the Great Dan is not willing to give up." Therefore, in the early Chinese Danshu, saltpeter was the protagonist.

In the Qin Dynasty, a large number of saltpeter mines existed.

Saltpeter in nature is often formed by the decomposition of nitrogen-containing organic matter in the soil under the action of bacteria, oxidized into nitric acid, and then combined with potassium in the soil. Therefore, whenever the autumn season is high and cool, it usually precipitates out in the form of a crust or salt flower, covering the ground and the foot of the wall, which is called ground frost. Especially in the corners near pigsties, stables, and toilets.

The nitrate people sweep this kind of soil containing nitrate, put it in a bucket, and soak it in water. After filtration, the filtrate is boiled or dried to obtain saltpeter crystals. In addition, it can occasionally be found on certain rock faces, caves, or salt marsh areas.

And sulfur has long been mined and used in large quantities, so the raw materials of black powder are complete, and for Li Yang, the most important thing is the proportion of black powder.

The folk saying "one nitrate, two sulfon, and three charcoal" refers to the mass ratio of the three components of black powder.

It's just that the formula formula of black powder "one sulfur, two nitrate and three charcoal" should not have been handed down very early, because the proportion of gunpowder preparation in ancient times is not like this, so it can be seen that the saying of "one sulfur, two nitrate and three charcoal" is likely to be the memory formula of later generations, and I suspect that most of it was done by middle school chemistry teachers.

Of course, as a traverser, Li Yang was very aware of the proportion of black powder.

The standard ratio of gunpowder preparation should be, potassium nitrate:sulfur:carbon = 15:2:3

The chemical reaction is based on black powder of 1 sulfur, 2 nitrate and 3 carbon, and the actual mass ratio is: potassium nitrate accounts for 75%, sulfur accounts for 10%, and carbon accounts for 15%. (2KNO3+S+3C=ignition=K2S+N2+3CO2)

For Li Yang, who knew the proportion of gunpowder, the production was extremely simple, and when He Zhang ordered someone to take the raw materials, Li Yang would grind saltpeter crystals, sulfur, and charcoal into powder, and then mix them together in proportion.

In a short time, the black powder was simply prepared and put in a bowl, which was enough for a bowl.

Looking at the black powder mixed with the three raw materials, He Zhang asked with a somewhat questioning expression: "My lord, this is an invention comparable to papermaking, gunpowder?" ”

Li Yang nodded: "That's right, this is gunpowder." ”

He Zhang looked left and right, a little incredulous, no matter how you look at it, this is too simple, it is difficult for people to compare it with papermaking.

"Come on, let's experiment!"

Li Yang actually wanted to know whether the black powder he had prepared would work or not.

So he immediately took a spoonful, placed it on a piece of paper, and then stretched out a branch to ignite it.

I only heard a "snort", and a ball of fire suddenly burst out, igniting a puff of smoke. Seeing this scene, Li Yang knew that the black powder was a success!

"Wow!"

He Zhang's face was bright, obviously thinking that this little experiment was very interesting.

So he picked up the small branch that was still burning from the ground, and stabbed it at the bowl of black powder on the ground......

Li Yang looked at it, and it!

Directly frightened, he exclaimed, and just wanted to stop it, but it was too late, only to hear a "bang", a fierce firelight exploded, and suddenly Li Yang only felt that his eyes were dazzled, and he couldn't see anything.
