Li Yang, who was so thundered by He Zhang, had no choice but to make it out of stock, so he had to reiterate clearly: "The name of it has been decided, it is called firecrackers and firecrackers! It cannot be called Yangbian. Is it clear enough?"

He Zhang nodded with admiration and praised: "I really regard fame and fortune as nothing, and honor as dirt, gunpowder, and firecrackers, which are as famous as papermaking, but can resolutely abandon it. This state of indifference to fame and fortune really makes my subordinates admire him. Since I decided to give up naming this thing after my own name, my subordinates are disrespectful. I decided to call it He Yao, Zhangbian!"

I, Zhang, your sister!

You bitch, you're simply shameless!

Li Yang was speechless and made a stern decision: "Did you hear clearly? You are not allowed to call Yang Yao or Yang Wu, let alone He Yao. Zhang Wu can only call gunpowder, firecrackers, and firecrackers. You can't change a word."

"Aren't they all whips?" The bitch He Zhang couldn't help but curl his lips 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: "Sir, 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 you can make gunpowder together in proportion."

"Oh? It's so easy!"

When He Zhang heard this, it turned out that gunpowder, which was as famous as papermaking, was so simple to make, but it was just a comparison of three raw materials. He couldn't help but be overjoyed: "Saltpe, charcoal, and sulfur will be ready for the house. The master told me how to match the proportions. I will then order people to compare hundreds of kilograms of gunpowder."

Li Yang thought to himself, you still don’t know the characteristics of gunpowder at all, so you just make hundreds of pounds. Once it explodes, you won’t be able to kill you all?

So he waved his hand and said, "No hurry, this thing is a dangerous product. Once it is ignited, it will be very dangerous."

"Oh? Gunpowder is dangerous?"

He Zhang finally became alert.

Li Yang nodded: "Yes, gunpowder is powerful. After igniting, it will instantly release huge heat, resulting in an explosion."

"explode?"

He Zhang was stunned and asked in confusion: "Sir, what is an explosion?"

Li Yang said: "Well, if you get hundreds of kilograms of gunpowder, once it ignites, your workshop will be radiated to the ground by the tension generated by the huge heat it releases."

"Ah? The whole workshop was razed to the ground!"

At this moment, He Zhang became solemn and said in surprise: "The lethality is so huge. If it can be used for military combat, wouldn't it be stronger than Qin Crossbow?"

Li Yang looked at him in surprise, thinking that this guy is really a talent. Just by hearing the characteristics of gunpowder, he knew its huge potential in military aspects.

At this moment, Li Yang really admired this bitch. Although this guy was a little shameless,... it was indeed a piece of gold.

You should know that although Chinese alchemists used saltpeters to refine alchemy during the Warring States Period, strictly speaking, gunpowder was invented by Ge Hong of the Jin Dynasty. Moreover, China invented gunpowder, and in the long history, it was only used in firecrackers and fireworks. They truly promoted it in the military, invented guns, cannons, or foreigners.

The He Zhang in front of him was based on the sentence that gunpowder would explode, and immediately thought of its military use. This kind of vision was 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 and the form of war."

Speaking of this, in order to better understand He Zhang, Li Yang added: "It is no exaggeration to say that as long as you can use gunpowder to develop advanced thermal weapons, Qin will be able to easily become the world overlord and quickly rule Qin's ball. In short, gunpowder has unlimited potential in military aspects."

Li Yang did not lie to him. Gunpowder was a powerful weapon in war, and directly ended the era of cold weapons that had lasted for thousands of years!

He Zhang's eyes were already lit when he heard Li Yang's words, his face flushed, and his blood was boiling with excitement. He quickly said, "Have you thought about how to use gunpowder to make weapons?"

Li Yang nodded and said, "I do have some ideas, but... I should prepare the gunpowder first and make some firecrackers first. As for how to use it into a weapon, I will talk about it later."

He Zhang nodded: "Yes, after gunpowder is invented, we will invent gunpowder weapons that can razor the house 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 mansion, because saltpeter was used as medicine during the Warring States Period. In particular, alchemists attached great importance to saltpeter, saying that it was "generated from the qi of the sea, and it was the most magical thing of heaven and earth... It can transform seventy-two petrols into water, soften the hardware, and refine eight stones. Even the great elixir is unbearable." Therefore, in early Chinese alchemy techniques, saltpeter was the protagonist.

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

Saltpeter in nature is often formed by decomposing nitrogen-containing organic matter in the soil under the action of bacteria, oxidizing it into nitric acid and combining with potassium in the soil. Therefore, whenever the autumn season is clear and cool, it usually precipitates out in the shape of a shell or a salt flower, covering the ground and the foot of the wall, which is called ground frost. Especially in pigpens, stables, and toilets, there are many corners of the walls.

The nitrogen sweeps out the tinea block, puts it in a barrel, and soaks it in water. After filtering, the filtrate is boiled or dried to obtain saltpeter crystals. In addition, it is occasionally found on the surface of some rocks, caves or salt marsh areas.

Sulfur has been mined in large quantities and used, so the raw materials for black gunpowder are complete. For Li Yang, the most important thing is the preparation ratio of black gunpowder.

The folk saying "one nitrate, two sulfonates and three charcoals" refers to the mass ratio of the three components of black gunpowder.

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

Of course, as a time traveler, Li Yang is very clear about the preparation ratio of black gunpowder.

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

The chemical reaction is based on black gunpowder with 1 sulfur, 2 nitrate and 3 carbon. 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 knows the ratio of gunpowder to prepare, the production is extremely simple. After He Zhang ordered people to take the raw materials, Li Yang grinds saltpeter crystals, sulfur and charcoal into powder and mixes them together in proportion.

Soon, the black gunpowder was prepared simply and put in a bowl, with a bowl.

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

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

He Zhang looked left and right and couldn't believe it. No matter how you look at it, it was too simple, and it was difficult for people to compare it with papermaking.

"Come on, let's experiment!"

Li Yang actually wanted to know whether the black gunpowder he prepared was good or not.

So I immediately took a spoonful, placed it on a piece of paper, and then stretched over it with a branch to ignite it.

Only a "sneer" sound was heard, a ball of fire suddenly rose, igniting a thick stream of smoke. Seeing this scene, Li Yang knew that the black gunpowder had succeeded!

"Wow!"

He Zhang looked brilliant, obviously thinking that this small experiment was very interesting.

So he picked up the ignition branch from the ground, stabbed it at the bowl of black gunpowder on the ground...

Li Yang saw it and said, "Damn it!"
