Chapter 1343 Principles
After discussing the matter of the Ministry of Completion, Chen Qing said with a smile to everyone: "Next, let's discuss the second matter, which is about the restructuring of the army. The establishment of the Yong Kingdom requires the regularization of the army. The old way is no longer feasible. So take this opportunity, let me discuss with you all the political participants, how to change it?"

Zhang Xiao pondered for a while and said, "I have also considered several plans, but none of them are suitable. I suggest to seek advice from the generals of the army, listen to their ideas, and respect the interests of the army, so that there will be no civil servants to formulate a military system. disadvantages."

Several political participants supported Zhang Xiao's suggestion. Chen Qing heard the tacit understanding between them, and immediately understood in his heart that the army was his base, and the political participants in the Internal Affairs Hall were very afraid of the army and were unwilling to easily participate in it.

Helpless, Chen Qing had no choice but to smile bitterly and said, "Okay! I'll find a chance to talk to them and listen to their opinions."

At noon, Chen Qing didn't go out and had lunch in the official office. At this time, Wei Ji said at the door of the official room: "Your Highness, they are here!"

"Take them to the chamber and wait, I'll be right over."

Although Chen Qing puts his energy into government affairs, the gravity clock is also a major event. It not only has a great impact on the lives of the people, but also has a great impact on marching and fighting. No matter how busy Chen Qing is, he still wants to make the gravity clock come out.

He took the blueprint and walked quickly to the meeting hall.

There are four people sitting in the meeting hall, Professor Yan of Taixue University and his favorite student Song Zhu. Professor Yan's full name is Yan Kuo. like a teacher.

The other two are treasurer Xu Da of Jubao Pavilion and Li Si, a goldsmith. The two groups were originally irrelevant, but Chen Qing brought them together.

However, Yan Kuo knew Li Si, a goldsmith, and Li Si's fine workmanship was exquisite. Yan Kuo once wanted to invite Li Si to give lectures in the imperial academy, but Li Si was too busy and had no time, so he had to give up.

It's just that they didn't expect that they would meet again in King Yong's official room.

At this time, Wei Ji walked in with Chen Qing, and the four of them quickly got up to salute.

Chen Qing asked with a smile: "Do you know each other?"

Yan Kuo smiled wryly and said: "Bizhi originally wanted to invite Master Li to give lectures at the Imperial Academy, but he was too busy to have the opportunity."

"Oh! There may be a chance in the future."

Chen Qing invited the four of them to sit down, and said again: "I guess none of you have had lunch. Later, you go to Qingfeng Teahouse to eat and drink tea, and put it on my account. I invite you today!"

"Your Highness is too polite!"

Chen Qing said to Wei Ji again: "You take them to dinner later."

Weiss nodded.

Only then did Chen Qing say to everyone: "The four of you are invited here today because I want to make something, to be precise, a timekeeping tool, you all know the hourglass!"

The four of them nodded, and Chen Qing said again: "The hourglass relies on the precise flow of fine sand to make the gears rotate, and then the villain accurately shows the time. If you are not careful, the amount of sand produced by the hourglass will be inaccurate, and then the timing will be messed up. The same is true for the hourglass. It is driven by water, which is troublesome and not easy to be accurate. I wonder if I can let the gears rotate accurately by themselves.”

Song Zhu said: "No matter how the gear moves, it needs a force to drive it. I think this is the key."

"well said!"

Chen Qing glanced at him approvingly and said, "When I was giving a lecture to you two days ago, I mentioned a kind of force, boulders rolling down from the top of the mountain, do you remember?"

Yan Kuo and Song Zhu nodded. They all remembered that Master Xu and Li Si were confused, but they didn't say anything.

"I call that force the attraction of the earth, or gravity. No matter how high we throw a stone into the sky, the stone will fall to the ground. It shows that the earth has a force that attracts all things to go down, so water goes down. This principle."

Both Yan Kuo and Song Zhu nodded silently, they both felt a sense of enlightenment.

At this time, Chen Qing took out a small meteor hammer. It was not a rope, but a thin copper rod. The other end was hung on the handle and could move freely. Chen Qing smiled and said, "Let's do an experiment!"

The eyes of the four were all fixed on the meteor hammer. Chen Qing pulled up the copper rod of the meteor hammer and let go, and the meteor hammer began to swing.

"Have you seen that the meteor hammer is falling downwards, and there is a force to pull it downwards, so can the gears be driven by force?"

"Yes! Exactly."

Both Yan Kuo and Song Zhu understood and nodded together. This time even Li Si also understood. He made a golden hourglass, so he understood the principle.

"Then the meteor hammer swung back from the other side and pulled the left gear as well. The left and right gears rotated alternately, driving a large gear to rotate uninterruptedly, with very uniform force. Is this equivalent to uniform water flow or uniform fine sand?"

Chen Qing saw that everyone understood, and smiled again: "But there is a major problem here, that is, the meteor hammer will stop eventually, but I want the meteor hammer to never stop, what should I do?"

Everyone shook their heads in puzzlement, Chen Qing said slowly: "Actually, there is also a way, that is, to make a kind of grabbing device, the copper hammer swings to the highest point on the left, and there is a clip to catch the copper rod, then let go, and the copper hammer swings to the right At the highest point, there is also a clip to clamp it, and then release it, which is tantamount to starting again every time, so this grabber is the key to planting, I don’t know how to make it, I need you to discuss it with the craftsman.”

After a pause, Chen Qing asked again: "Do you understand the principle of this grappling device? This is the key point. If you don't understand, I can explain it again."

All four of them nodded to show that they understood. Although shopkeeper Xu didn't know what the source of power was, he understood what Chen Qing said about gravity, and he also understood the principle of the grabbing device, which meant that he had to start all over again every time.

Chen Qing took out the drawing, spread it on the table and said, "I've explained the principle to you clearly, so you can look at this picture again!"

Chen Qing drew two blueprints. The first blueprint was the principle he just talked about, the pendulum, the gears, and the grabber. The four of them could understand it at a glance.

"Is this what His Highness just said?"

"Yes! The key is the second picture."

Chen Qing unfolded the second picture, which is a bell tower with a huge hour hand, surrounded by twelve hours, Zi, Chou, Yin, Mao, Chen, Si, Wu, Wei, Shen, You, Xu and Hai, there are eight quarters between each hour.

"This is the Bell and Drum Tower. I need to make a big clock. Below is the pendulum. It is constantly swinging, driving the gear to rotate, and the gear rotates behind it, and then drives the long needle to rotate at a constant speed. See if it is long now. The position pointed by the needle is Mo Shi Mo!"

Everyone nodded together. With the explanation of the principle just now, they all understood the picture of King Yong's big clock at once. It is very simple and easy to understand. That is Mo Shi Mo.

Yan Kuo smiled and said: "Your Highness made it very clear, we all understand, and we will start looking for craftsmen when we get back."

Chen Qing told him: "It's one thing to understand the principle, but it's another thing for the craftsman to make it. After you go back, you must explain the principle clearly to the craftsman. If you don't understand anything, you can ask me." !"

Li Si asked in a daze: "This kind of big clock doesn't seem to have much to do with me!"

Chen Qing smiled and said to him: "You also go to Taixue to participate in the making of the big clock and learn it thoroughly. After you understand how to make it, your task is to make a small clock that can be placed on the table. "
