"Prince, we have already made the first batch of gunpowder according to the proportion, and we ask the prince to check it."

Shaofu Gong Cheng Zhanghan walked into Zhao Tuo's official office, looking a little excited, and reported to Zhao Tuo the results of this latest project called "gunpowder".

"Hey, I got it out so quickly, Shaorong is really capable."

Zhao Tuo was slightly surprised and praised Zhang Han.

It's only been a few days, and it's been done too quickly.

Zhang Han said with a smile: "Junhou gave a specific gunpowder formula, we only need to find the three materials, and then mix them according to this formula, so it can be completed quickly." ”

The gunpowder project was the first order issued by the Marquis of Gonggong after he took office in the Shaofu, and it was completed quickly, because the Marquis of Gonggong gave the proportion of the gunpowder formula recorded on the fragment at the beginning.

One nitrate, two sulfonate, three charcoal.

You don't need to explore too much, just find the three materials and mix them into powder according to this ratio, and you're done.

So not long after the project was launched, Zhang Han quickly completed it and presented the results to Wugong Hou.

"Well, let's go check it out."

Zhao Tuo had anticipation on his face.

Go with Zhang Han to a testing ground belonging to Shaofu.

Half an hour later.

Bang.

Listening to the popping sound that came to his ears, he watched the paper tube filled with black powder burn in front of him, exploding, and flashing a bright light.

Zhao Tuo's face was expressionless.

Zhang Han next to him was full of surprise.

Wugong Hou had an order that he must not touch the fire when he got this thing, so until now, Zhang Han didn't know that those black powders had such an effect, it was really amazing.

"Prince, this thing can emit light and explode, I don't know what the use is?"

Hearing Zhang Han's question, the corners of Zhao Tuo's mouth twitched slightly.

Use?

It can probably be used to make firecrackers for the emperor to hear.

Maybe after the First Emperor read it, he would frown and say to him Zhao Tuo: "You Zhao Tuo took my money and got this thing out?" ”

What a gunpowder.

Good a large firecracker.

This is what Zhao Tuo has been looking forward to for a long time, but it turned out to be this kind of bear.

Facing Zhang Han's inquiry, Zhao Tuo pushed it on the head of the ancestor with his hand.

"The fragment only says that if this thing can be made, it will have great effect, and it may be a powerful weapon, far more powerful than a cannon. It is a pity that the fragments are broken, only the recipe of the raw materials remains, and the process of how to use and improve is not recorded, perhaps it is lost, or it may be that the male loser has not had time to study it thoroughly. ”

Zhao Tuo sighed faintly.

Zhang Han was full of regret when he heard this, and said: "The male loser is a sage of the ancients, since he said that this thing is stronger than a giant cannon, naturally there will be no fake, but it is a pity that the fragment is lost, it is really a loss for my Qin State." ”

Listening to Zhang Han's sigh, it was a pity.

Zhao Tuo secretly smiled bitterly, he thought about it carefully, and found that the situation in front of him was actually normal.

It seems that gunpowder was originally only used for juggling, fireworks, and the like, and was not used in military affairs. Because the power of the original black powder was too weak, it could hardly hurt anyone.

In the Song Dynasty, under the threat of powerful nomads in the north, the Song people attached great importance to the testing and production of gunpowder and gunpowder weapons, and after a series of technological innovations, they could be used as weapons, and firearms such as assault muskets were produced.

Zhao Tuo knew the earthy formula of black powder, so he could easily figure it out.

But those technical problems in the middle, Zhao Tuo is not clear.

He estimated that the power of black powder was also related to the purity of its raw materials, preparation process, compression and sealing and other supporting technologies.

These things are by no means something that can be solved overnight, and it takes a lot of experimentation, and I am afraid that we can only explore it slowly.

"Looking at it this way, I'm anxious, the powerful gunpowder can't be made in a moment and a half, it's not enough to have a formula, and other supporting technologies have to keep up. So those who made gunpowder and killed all sides as soon as they traveled to ancient times, isn't it nonsense. ”

Zhao Tuo muttered in his mouth.

In fact, the current Qin State is prosperous and prosperous, and it is the top power in the world, and it does not need the blessing of gunpowder.

Zhao Tuo studied this thing, and he didn't expect this thing to be effective in war.

Because gunpowder is not only used to fight wars, but also has a great future in civilian use.

For example, it can be used for mining, road construction, water conservancy, engineering blasting, metal processing, etc., which can save manpower and material resources to a great extent, and is of great benefit to the improvement of national strength.

To put it bluntly, gunpowder is a must-have for an infrastructure powerhouse.

At the same time, it is also a necessary technology for the development of human civilization.

"You can keep a project team first, engage in long-term projects, and let people slowly carry out research. It's a pity that those alchemy monks were all killed by me, and I didn't even leave any seeds, otherwise with their participation, the result would be twice the result with half the effort. ”

Zhao Tuo shook his head.

After he served as the Shaofu, the first thing he thought of getting the gunpowder out was actually related to the fact that those alchemy alchemists were killed by him.

Zhao Tuo remembered that gunpowder originated from alchemy, and it was the product of those monks who used fire alchemy.

But the problem is that in this time and space, alchemy has just sprouted, and it was snuffed out by Zhao Tuo.

The pill is poisonous.

Let the Marquis of a country Lun eat poisoned in bed, the first emperor was furious, and killed all the medicine refining prescription doctors left in Xianyang.

When the alchemy practitioners in Shandong heard about this, they were so frightened that their souls scattered and changed their careers overnight.

Now in the entire Great Qin world, no one dares to openly preach the art of alchemy and immortality.

This matter is a very big blow to alchemy, with the First Emperor and Zhao Tuo as examples in the front, I am afraid that the emperors in the back will not believe in this kind of thing anymore.

And with Zhao Tuo's intervention, Lu Sheng, Xu Shi and other scholars came up with a mature immortal cultivation system, which dealt a huge blow to other factions that sought immortality, such as the overseas immortal seeking faction, which was directly killed.

Judging from the current situation, maybe the future Huaxia immortal cultivation system will only have one way to cultivate the inner pill, and the alchemy will directly lose the soil for its existence.

Without alchemy, the invention of gunpowder would naturally be gone.

Zhao Tuo took this into account, so he simply pointed out this technology, and easily pushed the invention of gunpowder to the public loser.

Regardless of whether he can make powerful gunpowder or not, he will let future generations know that such a thing exists. If it weren't for the death of Zhao Tuo, and at the same time the alchemy disappeared, I don't know how long it would take for gunpowder, one of the four major inventions, to be made.

The power of the gunpowder offered by Zhang Han was somewhat beyond Zhao Tuo's imagination, and after some encouragement, he asked Zhang Han to retain some manpower to continue to study this project, and other resources were transferred to other more useful projects.

For example, the improvement of metal smelting technology, the transformation of looms, etc.

These are all good things that can promote social development, can increase productivity, and are more important than gunpowder.

However, Zhao Tuo's new project had just begun, and the first emperor personally visited the Shaofu official office.

Zhao Tuo thought that the First Emperor had come to inspect his achievements during this time, and was thinking about how to deal with it, but the First Emperor came for another purpose.

He was not interested in Zhao Tuo's half-finished projects, the emperor was interested in something else.

"I will make a report from the Shaofu, saying that my imperial mausoleum has begun to take shape, I went to see it the day before yesterday, it is not bad, if it is repaired for another ten years, when there is the domineering spirit of the world's largest mausoleum, it can barely meet my identity."

Standing in front of Zhao Tuo, the First Emperor rarely talked about the Lishan Emperor's Mausoleum, which made Zhao Tuo a little surprised.

You must know that the First Emperor has been praying for immortality, fantasizing that he can become the sun that never sets and rule the world forever.

Therefore, although the imperial mausoleum has been being built, the first emperor basically does not mention this thing in front of people, as if he wants to stay away from death, and this matter has almost become a taboo.

This topic is related to the life and death of the emperor, it is too sensitive, the emperor can mention it, but he Zhao Tuo didn't dare to talk nonsense, so he could only stubbornly say: "Your Majesty cultivates immortals, maybe you can live forever." ”

The First Emperor shook his head with a smile and said, "Although I am cultivating immortals, I aspire to live forever. But he also knew that the immortal road was slim, and birth, old age, sickness and death were the norm in the world, and it was difficult for mortals to resist, so he had long been ready to go to the underground world. ”

"Your Majesty is wise."

Zhao Tuo arched his hand, but he didn't expect the First Emperor to still see it.

But the next moment, the words of the First Emperor startled Zhao Tuo.

"I went to Lishan to take a look around, and saw that the imperial tomb was majestic and magnificent. And the city of the Six Kingdoms is surrounded by my imperial tomb, and the remnants of the Six Kingdoms in the city guard the mausoleum for me, which looks good. ”

"But I always feel a little uncomfortable in my heart, so I want to deploy thousands of troops around the Emperor's Tomb as my guard in the underground world."

"In this way, there needs to be a general in command."

When the First Emperor said this, his eyes were fixed on Zhao Tuo.
