Chapter 139

"Ah, for the benefit of the people, I am willing to do anything."

In the face of the strange eyes of aster and lvluo, Xiao Ming also expressed his loyalty to the country.

At this time, aster and lvluo stopped laughing, but looked at Xiao Ming with reverence. In their eyes, Xiao Ming now can be compared with each other.

But in ancient times, which girl in the boudoir did not like the elegant scholar, the handsome king? This can be seen from the gaudy novels since ancient times.

Xiao Ming, the predecessor of Xiao Ming, only knows how to bow hard and how to understand women's psychology. It's a real pleasure to take a boat with the water.

Leaving behind a tired figure, Xiao Ming went back to rest. Now is not the time to lie on the knees of a drunken beauty.

At noon the next day.

"Bang!" a loud noise came from the cannon, which made king Qi's house quiet. The bodyguards in king Qi's house rushed to the place where the noise appeared after the loud noise.

When they arrived at the side hall, they found that the king of Qi was safe and sound. However, all the people outside the king of Qi were pale and seemed to be scared.

In the middle of the side hall, a glass bottle was blown to pieces, glass fragments fell to the ground, and the remaining glass fragments were still emitting smoke.

"Your Highness, this is the power of gunpowder?" Lu Tong said to Xiao Ming.

Xiao Ming nodded, "exactly."

Lu Tong sighed for a while. He said, "if it's a barrel of gunpowder, won't it blow up the whole palace?"

With these words, Lu Tong saw Xiao Ming and others throwing malicious eyes at him. Then he realized that he had said something wrong. He said, "look at my broken words, your highness. You know I will say something wrong. It's not to blow up the palace, it's to blow up the College of culture and Museum. No, no, blow me up..."

During this period of time, Xiao Ming also understood Lu Tong's problems and grasped what he said. He said, "be careful. You can blow yourself up at that time. I can't save you. By the way, you can see the power of the gunpowder. Next, you have to master the method of granulating the gunpowder."

Lu Tong doesn't know anything about this term. Just like last night, Xiao Ming is going to show it to Lu Tong himself.

In fact, the granulation of gunpowder mainly involves the addition of binder, which is the cold mixing method. In fact, the process is not so complicated.

In short, the mixed powder is put into the mortar, and then alcohol is added to mix the three kinds of powder into a wet mud state.

At the same time, the wood pestle is used to continuously stir, in this process, the stone sand can not be allowed to enter, otherwise, it is easy to bump in the process of mixing, and the gunpowder will burn.

Now Xiao Ming is demonstrating to Lu Tong in this way. The traditional black powder is powerful, but there is one way. In the process of powder storage and transportation, different components in the powder will be layered.

This is just like the liquid with different densities will be layered. In this way, the efficiency of gunpowder will be greatly reduced and the use of firearms will be affected.

Gunpowder granulation is not a high-tech problem, but the ancients didn't realize it when they first used gunpowder.

Now Xiao Ming understands these, and naturally solves this problem on the premise that it can be realized technically.

Lu Tong stares at Xiao Ming's operation all the time for fear of missing something. It's fatal to neglect it.

"Remember, sand and stone must not be involved, and iron and copper must not be used for grinding." Xiao Ming reminds me again.

Wooden tools are used in the whole process of grinding gunpowder to prevent metal collision and fireworks.

After mixing the gunpowder, Xiao Ming added water and rammed it again to make the mixture mix evenly.

Then Xiao Ming took out the powder and dried it in the sun.

Because it was already spring, the sun was relatively abundant, and the amount was not large, so the powder soon dried.

At this time, quality inspection will be carried out.

At this time, Xiao Ming took part of the dried powder particles and put them on the paper to ignite.

The burning powder was very fast, but the paper in Xiao Ming's hand was intact. He nodded and said to Lu Tong, "see? How to achieve this effect shows that gunpowder is successful. "

Lu Tong nodded, and then Xiao Ming put the powder in his palm and wanted to light it again.

Lu Tong then said: "Your Highness, let me do this, so as not to hurt your highness."

"Well, let you feel it." Without waiting for Lu Tong to react, Xiao Ming quickly ignited the powder.

The burning of granular powder in the palm of Lutong's hand ended quickly.

At this time, Lu Tong said in surprise, "Your Highness, I don't feel hot at all."

"Heat means that the manufacture of this powder has failed. OK, you should teach all the things you need to teach. After you go back, the production of this powder will be put on the agenda. Remember, if there are black stars and white spots on the paper, or the palm of the hand has a burning feeling, this powder is unqualified. It needs to be reworked and then milled until it is qualified. Finally, the powder particles need to be screened, and the powder must be made first The formed powder is broken into particles one by one, and the powder particles suitable for the cannon are screened out by using a sieve of different thickness. As for the powder that is not granular, it is used as the fire gate to draw the powder, and the remaining fine powder is removed completely. " Xiao Ming said.Lu Tong nodded. It's not difficult for him to understand the powder. He bowed, turned and left the palace.

At this time, Xiao Ming said, "Lu Tong, the matter of gunpowder is very important. We must not be careless. If something goes wrong, I will chop your head."

Lu Tong's intuition is that a chill is rising behind his back. These days, Xiao Ming and he can be said to be close like masters and apprentices. However, on this issue concerning the safety of Qingzhou, Xiao Ming does not care about human feelings.

He turned around and said, "if something goes wrong, Lu Tong will come to see you."

Xiao Ming nodded, technology is on the one hand, craftsman's spirit is on the other hand, no matter how superb technology is in front of irresponsible craftsman, what can be produced can only be rubbish.

The modern Ming Dynasty is not that the manufacture of firearms is not advanced, but that there are many problems in the production process.

The reason why the produced firearms could not go to the battlefield was that many Ming army soldiers could not fire the firearm at all, and the artillery exploded at a little bit.

Therefore, in the industry of Qingzhou, Xiao Ming has always paid attention to the cultivation of craftsmanship spirit and put an end to all rough manufacturing. In this regard, he does not speak of any human feelings.

Because he didn't want to destroy the steel foundation he had painstakingly built, and the barbarians and Dayu people who were waiting to see his jokes would not give him a second chance.

Just as Lu Tong went out, a soldier suddenly rushed in and said in a loud voice, "Your Highness, something's wrong. Captain Lu and captain Luo are fighting."
