Zhu Youxiao turned to look at Sun Yuanhua, his eyes were never more serious.

"It was ordered that this mercury could only be used as a fuse for artillery shells, and that each fuse made into a shell must be stored separately."

"What I mean is that each one must be stored separately, and in this process, it is absolutely not allowed to open flames, away from heat sources, to prevent direct sunlight, and it is strictly forbidden to hit, squeeze, fall, roll, and rub."

"If I hear that this kind of thing has exploded due to centralized storage or other reasons, I will ask for your Sun Yuanhua's head."

When Sun Yuanhua heard Zhu Youxiao's words, his face gradually became serious.

"Please rest assured, Your Majesty, Weichen will personally supervise and do what you say."

Zhu Youxiao nodded, "It's good that you know, it's getting late today, and it's too late to make new explosives." ”

"Tomorrow! Tomorrow we will get new explosives. ”

Sun Yuanhua looked at Zhu Youxiao with a little shock.

He didn't expect that there would be a new type of gunpowder manufacturing.

He remembered that Zhu Youxiao had gone to see Zhu Yuanzhang, it seems that this Emperor Taizu has also learned a lot of things in heaven!

Sun Yuanhua's teacher before wanted to pull him along and join Christianity.

He was a little hesitant now.

Maybe if you don't believe in Christianity and believe in Taizu Emperor Zhu Yuanzhang, it's the same thing!

However, compared with his curiosity about Zhu Yuanzhang, Sun Yuanhua was even more curious about what kind of gunpowder Zhu Youxiao said.

The maroon gunpowder is already so fierce, can this new gunpowder be more fierce than this maroon gunpowder?

Zhu Youxiao has already gone back.

But the next day, when he came to the arsenal again with a large guard, he saw that this Sun Yuanhua was already waiting at the door.

Obviously, Zhu Youxiao looked at Sun Yuanhua's dark eyes, and knew that the other party hadn't slept all night.

Zhu Youxiao complained a little, and started to play tricks again.

"There are important things to do today, why didn't Sun Aiqing rest early last night?"

"You need to know that Se is a sharp knife to scrape bones, knives and knives cost people's lives, you cherish yourself so much, how dare I hand over the responsibility of my family and country to you?"

The surrounding officials and guards all snickered when they heard Zhu Youxiao making fun of Sun Yuanhua.

Sun Yuanhua also blushed.

"Back to Your Majesty, Weichen really can't sleep!"

"Wei Chen saw that thunder mercury was so powerful yesterday, and knew that His Majesty would guide us today. Making a new type of gunpowder, Wei Chen was excited when he thought of this, how could he sleep. ”

Zhu Youxiao didn't say anything more, maybe this is a technology nerd!

In his previous life, he was like this, in order to study a new material ratio, he could also sleep and boil his eyes like a rabbit.

And what Zhu Youxiao wants to teach them to do today is indeed another epoch-making thing.

That is the legendary nitration powder.

The power of this kind of thing is almost ten times greater than that of black powder.

Only when this kind of gunpowder is contained in the flowering bomb can the power of the flowering bullet be truly displayed.

The three main materials needed to make this nitrifying explosive are nitric acid, sulfuric acid and glycerin.

Zhu Youxiao has already produced nitric acid, which is naturally not too difficult.

And sulfuric acid is even simpler, and there is no need for Zhu Youxiao to teach them how to make it.

In fact, the basis of the modern chemical industry is "three acids and two alkalis".

The "three acids" are sulfuric acid, hydrochloric acid, and nitric acid, and the "two bases" are caustic soda and alkali (sodium carbonate).

In Zhu Youxiao's impression, only sodium carbonate was a commonly used chemical material in ancient times.

Who makes noodles and doesn't put alkali in steamed buns?

In fact, in ancient times, sulfuric acid, nitric acid and caustic soda could be manufactured, and some people made them!

For example, in the ancient manufacturing method of sulfuric acid, the raw material used was alum, also called alum.

The main component of natural alum is ferrous sulfate, and when it is calcined in a closed container, sulfur trioxide is in the product.

And sulfur trioxide dissolves in water and becomes sulfuric acid!

Because this sulfuric acid is obtained by calcining alum, it is called "alum oil".

As for the production of that dry oil, it is a bit subtle.

Zhu Youxiao blushed a little when he thought of something like glycerin.

The reason is simple, glycerin can be made from natural oils.

For example, lard and so on.

And glycerin is actually a by-product of something else, and that is soap.

It's interesting to talk about things like soap.

It seems that any traverser who does not engage in glass, liquor and soap simply does not deserve to be called a traverser.

Before Zhu Youxiao didn't cross over, he was quite speechless when he saw these soaps in these travel novels.

Is there really so much soap that people can make?

He didn't believe it.

The problem is that Zhu Youxiao has crossed by himself now.

And, he really makes soap.

Doesn't this mean that he is essentially no different from other traversers?

In the end, it was like shaking his head, and all the messy things in his mind were thrown out of his mind.

He began to instruct these craftsmen in earnest, making nitroglycerin.

By the time nitroglycerin had already been manufactured, the explosive had not yet been fully formed.

Nitroglycerin can now be used as explosives, but it's too unstable.

With the current road conditions, horse-drawn carriage transportation is sure to produce bumps.

And in the process of bumpy transportation, almost eighty or ninety percent of nitroglycerin is going to explode.

So Zhu Youxiao must improve it and make it stable enough.

As for ways to improve the instability of this nitrifying explosive, Mr. Nobel has already given an almost perfect answer.

Zhu Youxiao directed the craftsmen to use three parts nitroglycerin and one part diatomaceous earth, plus a little sodium carbonate, to make the explosives stable and transportable and storeable.

This way, when nitrifying is exposed to a small fire, the explosive will burn but will not explode.

Therefore, a small explosion is required to detonate nitroglycerin explosives.

But Zhu Youxiao has already made a thundermercury fuse before, which is naturally not a problem.

When these craftsmen got the nitrifying explosives out, they put them in an iron can.

It took a long time to make a fist-sized piece of nitrification explosive.

But according to Sun Yuanhua, it is estimated that the cost of gunpowder at this moment is about to approach hundreds of taels of silver.

Where is the gunpowder that this cannon fired?

That's silver!

Sun Yuanhua even began to think in his heart, whether His Majesty had let people deceive him.

How can there be such a gunpowder, the cost is still so high.

Then, under the gaze of Zhu Youxiao and Sun Yuanhua, they carefully took the jar to the hillside outside.

In addition, they also placed more than a dozen sheep around the hillside.

Sun Yuanhua looked at the jar expectantly.

Zhu Youxiao, who was next to him, had already brought two balls of cotton and plugged his ears.

Then he took two more balls of cotton and handed them to Sun Yuanhua.

Sun Yuanhua saw this and refused on the spot.

"Your Majesty, Wechen often hears the sound of gunpowder exploding, and he has long been used to it."

"And we are so far away, even if this gunpowder explodes, there is not much movement coming, please don't worry about your majesty."

Zhu Youxiao nodded and didn't continue to pay attention to him.

It's hard to persuade damn ghosts with good words.

I saw that after Zhu Youxiao blocked his ears with a cotton coat, he tied his hat a little tighter.

This made Sun Yuanhua feel a little surprised.

That's right, too.

His Majesty has always lived in the palace, he has seen little gunpowder explosions, and he has never seen much of the world, so it is normal to have such a move.
