Chapter 138

"Your Highness, can this powder really explode?"

In the dark night, there was only some light in the side hall of the palace. Lvluo was very timid and wanted to cry.

Aster glared at Lu Tong and said, "thank you, your Highness has chosen to study chemistry. Go, go, let me do it."

Having said that, the aster took over the work of Lutong and ground up the saltpeter carefully.

Lu Tong looks embarrassed. How can a man lose to a weak woman? He calms down for a while. He doesn't speak and grinds again with a rolling pin.

This time, Xiao Ming called Lu Tong to teach by himself. Although the gunpowder is not a secret in the state of Dayu, it is not everyone can master it.

And this time he used a sulfur, two nitrate and three charcoal ratio is the best ratio of black powder.

During this time, Xiao Ming inquired about the proportion of black gunpowder in the state of Dayu. He got a lot of strange conclusions. There are all kinds of proportions. It's a mess.

The power of the gunpowder prepared according to these proportions can be imagined.

Therefore, starting from the production of gunpowder this time, his gunpowder ratio is dominant.

Naturally, Lu Tong didn't know the ratio. After this teaching, he realized that he had to be responsible for the production of gunpowder.

After all, it's one thing to produce artillery. In fact, there are a lot of artillery equipment projects. Gunpowder, artillery shells and artillery base are all things in the future.

But tonight, Xiao Ming is not only to teach Lu Tong how to produce the traditional black powder of Dayu, but also to further upgrade the black powder to granular powder, which is also a way to enhance the power of black powder.

As for the granulation of gunpowder, it had already appeared in the West in his time in the 15th century, so it was not a difficult problem technically.

After the three of them ground the sulfur, saltpeter and charcoal into fine powder, according to Xiao Ming's request, Lu Tong mixed the three materials according to the proportion of gunpowder.

Suddenly a small pile of black powder appeared in front of the four people.

"Your Highness, is that it?" Lu Tong asked, looking excited. This process is not dangerous.

"Well, yes." Xiao Minggang is just bluffing Lu Tong. It's not dangerous to grind the three materials separately. It's really dangerous now.

Lu Tong had only heard of gunpowder before, but he had never seen it before. Then he said, "Your Highness, how to use this gunpowder?"

The first gunpowder in Qingzhou was born under his own hands. Xiao Ming was also a little excited. He took some of the gunpowder out of the pile and took it to a far place.

Then he took a twig and lit it on the candle.

"That's how it works." When Xiao Ming finished, he touched the gunpowder with a branch. With a "Yi" sound, the gunpowder on the ground suddenly made a light sound, followed by a thick cyan smoke and gunpowder smell.

"Ah..." Lvluo is not ready, so she screams and hides behind Xiao Ming.

Although the aster is bold, it is also white.

The gunpowder burned very quickly and disappeared after a white light. They had never seen such a strange thing. They didn't know they thought it was magic.

Lu Tong was worried at first, but now that he had seen gunpowder, he was not afraid.

"Your Highness, the gunpowder burns so fast." Lu Tong said, "but that's all. It can't kill the barbarians."

"Of course not, but you'll know later." Xiao Ming waved, and a servant came up with something like a column.

Seeing this, Lu Tong asked, "Your Highness, what is this?"

Xiao Ming laughs. This thing is actually the shell of a firecracker rolled up with paper by his servant.

At this time, the firecracker was sealed with yellow mud, and a hole was left on it to hold gunpowder.

"You'll know by tomorrow." Xiao Ming took the powder and put it in. He also took some yellow mud to plug the top of the firecrackers.

At the same time, a needle is used to leave a hole on it, which can be used for lighting in the future.

After that, Xiao Ming took the firecracker to dry. When the yellow mud on it solidified, the firecracker could be used.

Originally, Xiao Ming wanted to teach Lu Tong how to use cold mixing granulated gunpowder, but it was too late to make black gunpowder, so he planned to leave it for tomorrow.

Let Lu Tong come back tomorrow, Xiao Ming ask aster to clean up things, this gunpowder production teaching is over.

Seeing Lu Tong off, aster and lvluo did not go back to rest, but still followed Xiao Ming.

After stretching, Xiao Mingqi said strangely, "why don't you go back?"

"Your Highness works hard for government affairs day and night, but now we have to work hard for the barbarians. Lvluo and I can't help your highness in government affairs. We can always serve your highness in daily life." Aster said cleverly.

Xiao Ming looked at them. In fact, since ancient times, people have always been heart to heart.

These days, Xiao Ming is good to the servants in the palace. Naturally, these servants are grateful to Xiao Ming.The servants in the palace worked harder than before.

"It's said that Qin women don't let men. Who says you can't help Wang in government affairs? I need your help then." Xiao Ming said suddenly.

Now Qingzhou belongs to the quiet period before the war. Everyone here should use it as much as possible.

The aster was surprised and said, "what does your highness need us to do?"

These days, the armor of the Qingzhou army has been solved for the time being, but the Qingzhou army can't wear armor naked.

This involves military clothes, shoes and other issues.

The barbarians are just around the corner. During this period, Xiao Ming had to change to the mode of vanguard for the sake of the army.

Nowadays, many soldiers of Qingzhou army wear straw sandals and hemp rope shoes, which inevitably leads to problems during the March.

So Xiao Ming thought about how to make the soldiers wear cloth shoes. In this era, men's workers and women's weavers want to solve this problem by organizing a large number of women to participate in this work.

However, it's not appropriate for men to come forward, because women in this era are basically unable to go out of the gate.

If aster and lvluo were involved in this, it would be different.

First, they are the people around Xiao Ming. They have enough prestige and no one dares to offend them. Second, they are both proficient in women's weaving and are familiar with this.

It's very appropriate for them to participate in the establishment of the first women's textile and clothing factory in this era. Otherwise, his loom technology would be wasted.

Thinking of this, Xiao Ming told them what he thought. Aster and lvluo laughed when they heard the words.

"Your Highness, we can help with this, but when will your highness know how to spin?" Aster covered his mouth and said with a smile.

In this era, men's work and women's weaving are purely women's business, and it is inevitable that aster will laugh.
