Du Yu rubbed his chin and thought for a while, and then said in deep thought, "Brother, although gunpowder was the first to be made by you, but now all the supervision and manufacturing power lies in the Shaofu Supervisor. The Shaofu Supervisor has such supervisory powers, and correspondingly Yes, the responsibility is very important."
Qin Meng smiled and said: "Brother, I understand what you mean, isn't it just worrying about my younger brother making fireworks. Will there be accidents? This matter is easy to do. Let’s do it in the gunpowder supervision department of the Shaofu Supervisor, although the venue is In the Office of the Shaofu Supervisor, but we must have the authorized documents, so that it can be justified."
"Okay, that's it." Du Yu finally figured out all the details and fully agreed.
"Brother, look. How refreshing is this? Excuse me, if you call Zheng Lun, my younger brother and him will immediately go to the Gunpowder Supervision Department, and we have to make samples as soon as possible."
Du Yu looked at Qin Meng strangely, and said, "What the hell? Brother, I'm in a good mood. I just started drinking, so you're going to tinker with that, the fireworks?"
"Brother, the situation is compelling. I have been in Jingzhao Fu Yin for more than a month, little brother, in order to gather people and repair the government office. During this period, as long as it is not a homicide case, all will be delayed. When I get started, there is. When the younger brother is too busy to die, it is possible to die from exhaustion if he does not hurry up."
Du Yu grinned in surprise, and pointed at Qin Meng and said, "Qin Meng, you really belong to you. It is estimated that Da Sui is just such a wonderful work for you. You have not started political affairs for more than a month in office? Well, you cow, I’ll send someone to call Mr. Zheng, hey, don’t forget, Mr. Zheng is a member of our young governor, so don’t pay it back."
After speaking, Du Yu called out the people outside the door loudly. Let him quickly invite Zheng Lun over.
When Qin Meng saw Zheng Lun, he was excited and emotional.
However, the two didn't have much time to relive the past. After Qin Meng said his thoughts, Zheng Lun obtained Du Yu's consent and immediately took Qin Meng to the Gunpowder Supervision Department of the Shaofu Supervisor.
The gunpowder supervision department of the Shaofu Supervisor was more than a hundred times stronger than the simple workshop Qin Meng worked in Wuwei.
Regardless of the simplicity of the work environment. Various configurations are available, all are complete, and you can find them easily.
Qin Meng asked Zheng Lun to call the best gunpowder craftsman in the Gunpowder Supervision Department. When they met, they found that everyone knew each other.
Because the gunpowder itself was made by Qin Meng, the original craftsman. They were brought out by Qin Meng.
The Shaofu Supervisor incorporated the gunpowder craftsmanship into the state. The craftsmen Qin Meng brought out must be the best gunpowder manufacturing craftsmen. They were taken to the Shaofu Supervisor and became the best craftsmen of the Gunpowder Supervision Department.
People are familiar and easy to handle, Qin Meng immediately asked Zheng Lun to fetch pen and paper, and drew a rough sketch of the second kick on the paper.
"Did you see it? This is the simplest firework made by wrapping gunpowder in a paper tube. In the meantime, it was sealed with yellow mud and separated into upper and lower spaces, both filled with gunpowder. The bottom layer. The tail was folded into petals with paper. Seal it, so that the lower layer of gunpowder explodes. It will not burst the whole, but form a jet port after the gunpowder explodes. This thing can go to the sky by the reaction force of the jet. Then, the middle lead is drawn in mid-air. Burning the upper part of the gunpowder will form a second explosion in mid-air, which is the so-called second kick."
Zheng Lun and the craftsman have long been accustomed to Qin Meng's fantastic ideas.
The craftsman was about to start but was stopped by Qin Meng.
"Don’t work in a hurry, there is still something to be changed. In this way, you go find some patina. It is broken into powder and added to the upper gunpowder. In this way, the upper gunpowder explodes in mid-air, and it will produce a different explosion color. ."
What Qin Meng said, the craftsman certainly didn't understand, it was a flame reaction in chemistry. Scientific knowledge that will take another two thousand years.
However, this does not affect the craftsman's pioneering ideas. He may not understand the scientific principles, but he can draw inferences from one another. Adding other metal scraps to the gunpowder can form a different style of firework colors.
The technical content of fireworks is actually not too high. As long as there is gunpowder, manufacturing materials, and a certain idea, it can be manufactured with a little adjustment.
Under Qin Meng's command, that night, he successfully tried a second kick, and it was a second kick with a special flame reaction.
This is something that Qin Meng sees as commonplace, but in the eyes of the people of the Sui Dynasty, it is a remarkable invention.
With Qin Meng's inspiration, coupled with Qin Meng's description of large-scale fireworks, soon, the craftsmen of the Gunpowder Supervision Department researched out very impressive large-scale fireworks.
Qin Meng was very satisfied with the results of the craftsman, and specially called Du Yu, leading the leaders of the Shaofu Supervisor, large and small, to the outskirts in the middle of the night.
When all the large fireworks bloomed, Du Yu was stunned. (End of this chapter)
