Daqin started with offering immortal medicine

Thinking of this, Li Yang said to He Zhang: "He Zhang, there is actually something whose sound is much louder than beating gongs and drums!"

"Oh?"

As soon as He Zhang heard this, he immediately became interested, and hurriedly asked, "My lord, what is it?"

Li Yang said: "Firecrackers, also known as firecrackers!"

"Firecrackers? Firecrackers?"

He Zhang frowned, thought for a while, and said: "This subordinate has never heard of this thing."

Li Yang smiled: "Of course you can't have heard of it, because it hasn't been invented yet."

He Zhang was taken aback, and immediately recognized it, and hurriedly said, "Your Excellency, have you made another invention?"

Li Yang nodded: "Yes, this firecracker is a good thing. Not only is it loud, but it also sounds more atmospheric than beating gongs and drums. With it, there will be atmosphere in the New Year; with it, there will be a New Year in the New Year Taste; put a hang on New Year’s Eve to bid farewell to the old year; hang a hang on the first day of the new year to welcome the New Year; hang a hang on weddings and ceremonies to create a lot of excitement and joy; firecrackers are really a must-have for New Year’s Eve, weddings and celebrations, and rewarding children ah."

"Oh, it sounds very good. Is it difficult to make it?" He Zhang has a natural interest in novelty, but if he just listens to the sound, if it is too difficult to make, it is obvious that he is not very motivated.

After all, he is now also a man who invented paper, printing, saddles, stirrups and other fetishes.

As for gadgets, it's not too cold.No way, this guy's heart has grown bigger.

Li Yang saw that he was not very interested in firecrackers, so he added: "It is not difficult to make this thing, but if you want to make firecrackers, you must first invent another thing. Call it 'gunpowder'."

"Gunpowder?" He Zhang frowned again, another new term.

Li Yang nodded: "That's right, gunpowder is amazing. In my opinion, gunpowder is an important invention that can be as famous as papermaking and printing. Of course, if you don't want to do it, then forget it, and I will go." Looking for Li You and Fu Su, these two guys should be very interested."

When He Zhang heard about the invention, which is as famous as papermaking and printing, he immediately yelled!He quickly grabbed Li Yang, nodded repeatedly and said, "My lord, I want to do it. I'm really interested in the so-called gunpowder and firecrackers."

Li Yang waved his hand: "Hey, why do you have to force yourself, I'd better go find Li You and Fu Su."

He Zhang hugged Li Yang's thigh and begged, "My lord! If my lord doesn't hand over this matter to my subordinates, my subordinates will definitely feel that life has lost its color, and life has no meaning. It's better to die!"

Li Yang saw it, sighed, and nodded, "Well, since you're so cheap, I'll let you invent it!"

He Zhang was overjoyed, and hurriedly said: "Don't worry, my lord, my subordinates have a conscience. As long as the firecrackers are made, I will name it Yangbian, and my subordinates will never take up the name."

Yang whip?

When Li Yang heard this, he almost stumbled and fell to the ground!

"I whip your mother so hard!"

Chapter 266 Gunpowder

Li Yang, who was driven into a frenzy by He Zhang, had no choice but to reiterate clearly: "I have already decided on its name, and it is called firecrackers and firecrackers! It cannot be called Yang Whip, have I made it clear enough?"

He Zhang nodded in admiration, and praised: "Your Excellency really regards fame and fortune as nothing, honor as dung, gunpowder, firecrackers and other inventions that are as famous as papermaking, but can resolutely abandon them. This state of indifference to fame and fortune , I really admire the subordinates. Since the adults decided to give up naming this thing after themselves, the subordinates will be disrespectful, so I decided to call it He Yao, Zhang Bian!"

I chapter your sister!

You bastard, you have no shame!

Li Yang was completely speechless, and snapped decisively: "Didn't you hear clearly, it is not allowed to be called Yang Yao, Yang Whip, let alone He Yao, Zhang Bian, it can only be called Gunpowder, Firecracker, Firecracker, and you can't change a single word. "

"Aren't they all whips?" He Zhang, a bastard, couldn't help curling his lips, and muttered angrily.

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

Li Yangdao: "To make gunpowder, you need three basic raw materials, saltpeter, charcoal, and sulfur. Then mix them together in proportion to make gunpowder."

"Oh? So easy!"

When He Zhang heard that gunpowder, which is as famous as papermaking, is so simple to make, it is only the ratio of three raw materials, and he couldn't help being overjoyed: "Saltpeter, charcoal, and sulfur are readily available in the general government. My lord told me How to match the ratio, the subordinates will order people to match hundreds of catties of gunpowder."

Li Yang thought to himself, you still don't understand the properties of gunpowder at all, so if you just prepare several hundred catties, once it explodes, won't you all be killed?

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

"Oh? Gunpowder is dangerous?"

He Zhang finally became vigilant.

Li Yang nodded: "That's right, gunpowder is very powerful. After it is ignited, it will release huge heat instantly, resulting in an explosion."

"explode?"

He Zhang was startled, and asked in confusion, "My lord, what is an explosion?"

Li Yang said: "Uh, if you get hundreds of catties of gunpowder, once it ignites, your workshop will be completely flattened 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 serious, and said in surprise: "The lethality is so huge, if it can be used in the army, wouldn't it be stronger than the Qin Nu?"

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

At this moment, Li Yang really admired this bitch.It's a bit brazen, but... it's gold.

You must know that although China had alchemists in the Warring States period who used saltpeter and other substances to make alchemy, strictly speaking, gunpowder was actually invented by Ge Hong in the Jin Dynasty.Moreover, China invented gunpowder, but in the long history, it was only used in firecrackers and fireworks, and it was really carried forward in the military. It was a foreigner who invented guns and cannons.

And this He Zhang in front of him, based on the saying that gunpowder will explode, immediately thought of its military use. This kind of vision is very rare.

Li Yang nodded in satisfaction: "You are right. Once gunpowder is used, it will definitely be able to replace the current weapons in the future, and even change the way the army fights and the form of war."

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

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

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

Li Yang nodded and said: "I do have some ideas, but... for now, let's prepare the gunpowder first, let's make some firecrackers first, and how to use 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 Jiang Zuo's mansion to prepare gunpowder.

There is no shortage of saltpeter in Jiangzuofu, because saltpeter was used as medicine in the Warring States period.In particular, alchemists attach great importance to saltpeter, saying that it is "born from the air of sea brine, and it is the most divine thing in the world... It can turn 72 petrochemicals into water, soften hardware, and make eight stones. Even the great pill will not give up. this".Therefore, in early Chinese alchemy, saltpeter was the main character.

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

Saltpeter in nature is often formed by the decomposition of nitrogen-containing organic substances in the soil under the action of bacteria, oxidized into nitric acid, and then combined with potassium in the soil.So whenever the autumn season is high and crisp, it usually precipitates out in the shape of a shell or salt flower, covering the ground and the foot of the wall. This is the so-called ground frost.Especially in the corners near pigpens, stables, and toilets.

The nitrater sweeps up this nitrate-containing clod, puts it in a bucket, and soaks it in water.After filtering, the filtrate is boiled or dried to obtain saltpeter crystals.Also, it is occasionally found on certain rock faces, caves, or salt marshes.
