Datang: My father is the head bodyguard

Yuchi Baoqi arrived at the Ministry of Works and found a bunch of iron fools waiting for him at the gate of the Ministry of Works. As soon as I got off the carriage, I was dizzy with questions from everyone.

Duan Lun was extremely angry: "How unbecoming is it to yell at the entrance of the Works Department! The iron workshop manager is my guest at the Works Department, and this is how you treat guests? Why don't you invite someone in to answer questions?"

Having said that, all the Tiehanhan didn't ask any questions and immediately ran to the Yamen of the Ministry of Industry with Yuchi Baoqi on their backs, barely carrying Yuchi Baoqi in.

Yuchi Baoqi stood in front of the table, looked at the sketch of the trebuchet and asked: "Didn't I tell you at the time that the lever arm was too short to throw it very far. Didn't you think it would be bigger?"

The craftsman scratched his head in embarrassment: "Sir, I tried it. Just make it bigger. The wood couldn't withstand such a strong force, and it disintegrated instantly, and several craftsmen were injured."

Yuchi Baoqi had a dark look on his face, "Don't your Ministry of Industry have safety regulations for production experiments when making things?"

Then Yuchi Baoqi took out a pencil and began to draw a structural diagram. While drawing, he explained to the craftsman: "After the moment arm is lengthened, the structural parts cannot withstand such a large force. I guess the main problem is at the connection point between the bracket and the ejection device. . The device I am drawing now is called a bearing. After the ironmaking workshop is completed, some can be produced as a connecting structural component. The bracket can also be replaced by I-beam steel. "

As the workpieces on the drawings were drawn one by one, the brains of the craftsmen seemed to have been hit hard with a hammer.

Some craftsmen immediately wanted to try using pig iron to make bearings, but Yuchi Baoqi stopped him. "The ductility of pig iron is too poor. Considering your current output of Baili Steel, it is impossible to use Baili Steel to make bearings. Don't think about it and wait."

This made the craftsmen who were about to move stop.

Duan Lun stared at the thing in Yuchi Baoqi's hand and asked: "Boy, what is this pen of yours? It makes drawings so smooth and fast."

Yuchi Baoqi handed the pencil to him: "This is called a pencil or charcoal pencil. It is made of wood on the outside and a mixture of graphite powder and clay on the inside. If it is bald, you can continue to use it by sharpening it with a knife. It is more convenient for sketching and painting." "

After hearing this, Duan Lun took the pen and wrote and drew on the paper according to the posture he had just seen Yuchi Baoqi holding the pen in. "It's really a divine thing. It's easier to hold the pen this way and it's easier to write." Come on, you don’t have to worry about being stained by ink. Wonderful, it’s really wonderful! I wonder if this method is possible,..."

Duan Lun regretted it as soon as he asked. He obviously asked Yuchi Baoqi to guide the craftsmen of the Ministry of Industry, but he focused on their craftsmanship.

Yuchi Baoqi smiled and said: "This method can give it to your Ministry of Industry, but I will take [-]%. You can ask yourself how much your Majesty wants. Whether it is internal funds or given to the Ministry of Household Affairs, this money must be given, otherwise Your Ministry of Industry cannot hold on."

Duan Lun was shocked. He actually agreed to hand over the method? This is a craft that can be passed down from generation to generation. I couldn't help but say: "Are you really willing to hand over the method to our Ministry of Works? In fact, you don't need to. I just said it casually."

Yuchi Baoqi waved his hand: "Duan Shangshu is very familiar with my approach, and the current mass production of charcoal requires a lot of manpower. I can't think of anywhere in the world except the Ministry of Industry that there are so many craftsmen. To the Ministry of Industry I’m willing to do it, so it’s settled.”

After that, he took out a few unused pencils from his arms and handed them to Duan Lun. He took back the pencil in Duan Lun's hand and wrote down the entire pencil process on the paper, including the proportion of graphite powder and clay.

Duan Lun looked at the drawings in his hand and asked with emotion: "You really don't plan to work in the Ministry of Industry? Even if you want the position of Minister of the Ministry of Industry now, I am willing to give it up."

Yuchi Baoqi stood up and patted the old minister on the shoulder: "You should still sit in this position, but don't change people. I have a lot of places for craftsmen to use, just in case the next minister of the Ministry of Industry takes the wrong path. , where can I go to reason with you?"

Duan Lun was very emotional, but suddenly thought that he had to report such a big thing to the emperor. This was a big change in the way of writing!

Duan Lun looked at Yuchi Baoqi and then in the direction of the palace like a headless fly. He gritted his teeth and said, "It's urgent. I have to go to the palace to report the matter to His Majesty. Just wait for me to come back at the Ministry of Industry. Let's Let’s have a good chat. You must wait for me to come back! Definitely!”

Yuchi Baoqi waved his hand to let him go quickly, then sat down and continued to answer questions for the craftsmen.

In the Ganlu Hall, Wang De said softly to Li Shimin who was reviewing the memorial: "Your Majesty, Duan Lun, Minister of the Ministry of Industry, has something to ask for."

Li Shimin put down the memorial, pondered for a moment and said, "Let him come in."

"Your Majesty, Duan Lun, pays homage to your Majesty."

"Excuse me, what's important, Mr. Duan?" After Duan Lun told Li Shimin what happened today, Li Shimin took a pencil and looked at it carefully. "Is this thing really so magical? Wang De, go get the dagger that Tibet paid tribute to."

Wang De ran all the way to get it, and Li Shimin sharpened the pencil under Duan Lun's guidance. Li Shimin held the pencil like a brush and wrote on the paper. Then he threw it on the table and said, "What a rag. It's not smooth at all. Duan Lun, you are here to make me happy." ?”

Duan Lun's heart skipped a beat and he quickly said: "Your Majesty, the usage of this thing is completely different from that of a brush. Let me give you a demonstration." Then Duan Lun picked up a pencil and wrote on the paper for Li Er to read.

The more Duan Lun wrote, the more Li Er blushed, thinking: "That's bad, I'm wrongly blaming this good old man."

Li Shimin said seriously: "My dear, this thing is so magical. I don't know how much faster it will be to use this charcoal pencil to deal with government affairs. Can the Ministry of Industry make it?"

Duan Lun quickly raised his hands and said: "Your Majesty, the ironworks general manager has taught the Ministry of Industry the production method and process of this thing. In the future, he wants two parts for production and sale. He also said that I will ask Your Majesty for the rest. How will the [-]% members from the Ministry of Industry, Ministry of Household Affairs, and internal funds be divided?"

Li Shimin pondered for a moment: "So this kid has made a meritorious service again? Thirty percent of these [-]% members go to the Ministry of Industry and [-]% to the internal funds. The Ministry of Household Affairs will only ask me for money, but this guy gives me money every day. I think it's better to let me It would be better for him to be the Minister of the Ministry of Finance!"

Duan Lun's heart tightened, "That won't work. Yuchi Baoqi is my intended successor. He must take over my job and be the Minister of the Ministry of Works!" . After thinking about it, he raised his hands and said: "Your Majesty, this son has unique insights in the investigation of objects. I dare to ask your Majesty to appoint him as the Minister of the Ministry of Industry. I beg for his bones and abdicate in favor of someone worthy of his position!"

After hearing this, Li Shimin also cherished it very much. The people recommended by Duan Lun were rare. Is Yuchi Baoqi really so talented? Then he said: "I have my own plans for this kid. He has a wild temper. I have to ask him where he wants to go. Don't mention the matter of begging for bones again."

Duan Lun had no choice but to give up. When he saw the dark sky outside, he thought, "Your Majesty, it's getting late and the palace gate will be locked soon. That guy is still waiting for me at the Yamen of the Ministry of Works when I get back. Please excuse me."

Li Shimin was fiddling with the pencil in his hand without looking at Duan Lun, and he hummed in his mouth as if he heard it.

Returning to the Ministry of Industry, Duan Lun looked at all the officials from the Ministry of Industry and found that most of them were wandering in a fuzzy state and making strange laughs from time to time. Some of them were holding their heads and their eyes were dull.

"Shang Shu, you are back. The general manager of the iron workshop got tired of talking all afternoon. After raising a question, everyone became like this." A waiter said with his hands.

Duan Lun asked in confusion: "What's the problem?"

"The general manager of the ironworks asked. Stones and iron of the same size fell from the same height at the same time. He asked whether the stone hit the ground first or the iron."

"Then it goes without saying that it must be iron. If it is the same size, it must be heavy. The iron must hit the ground first. Is there any need for everyone to be in despair?" Duan Lun wondered.

The waiter shook his head after hearing this: "The craftsmen said the same thing at the time, but the manager smiled and said that the Stone and Iron Works Department had plenty of them anyway. Wouldn't you know if you go and try them? As a result, these craftsmen ended up like this. The manager said I left when I heard the gongs and drums for the curfew."

After hearing this, Duan Lun walked up to a craftsman and asked, "Which one will fall to the ground first, the stone or the iron?"

The craftsman looked at Duan Lun in despair and said: "They landed together, they actually landed together! Minister! How could this be possible?"

Duan Lun was also shocked, so he went to the testing ground behind the Yamen and personally tried the iron and stone, and they actually fell to the ground at the same time!
