Early the next morning, I set out for Lishan with Meng He. There were only a few people in our entourage. Unlike Ying Zheng's mighty team of several hundred meters, the speed was much faster. We arrived at Lishan in about two hours. Someone was sent to notify Zhang Han yesterday, so when I got off the carriage, I saw Zhang Han waiting in front of the official office.
When Zhang Han saw me getting out of the car, he immediately stepped forward and bowed: "Your Highness, Zhang Han, has met."
I looked at Zhang Han carefully. He was also wearing a black robe, but there were no accessories around his waist. He was in his twenties and had a dignified appearance. In history, he once led the prisoner army to victory. Now his temperament looks more like that of a scholar.
I stepped forward to help him up and said with a smile: "You don't have to be polite, Colonel Zuo. The last time I followed my father here, I only stayed for a short time and didn't have much contact with Colonel Zuo. Today, I saw that he is indeed a talented person."
Zhang Han replied: "Your Highness has given you too much praise. Please go to the official office to rest first. I have summoned the officials and the main craftsmen here to wait for Your Highness in the office." There was a curiosity in his heart. The prince's tone seemed to recognize me?
If I knew what Zhang Han was thinking, I couldn't help but tell him. Not only me, but many people in future generations will know about you!
I followed Zhang Han into the Zuo Xiaoling Mansion, which was just the larger room among the thatched cottages.
There were already more than a dozen people lined up on both sides of the room. When they saw me coming in, they all said in unison: "See you, Your Highness!"
Zhang Han and I walked to the top position and said with a smile: "No need to be polite, please sit down." After that, I sat down first, and the others followed me.
"I didn't want to disturb you all when I came here today. However, I have been favored by the emperor. The emperor has entrusted me with important responsibilities. I dare not slack off at all. Please tell me about the progress and difficulties encountered, and I will work with you to solve them." Looking at the people sitting down, I slowly He said slowly, the people in black robes on the left should be the officials here, and the people in short robes on the right are craftsmen.
As soon as the words fell and Zhang Han was about to speak, I raised my hand and said, "There is no need to say more, Colonel Zuo. I will review your report carefully every day."
Zhang Han cupped his hands and said, "Yes, then I will report to His Highness one by one."
The person on the left raised his hands and said: "Your Highness, He Qizi, the official of the Stone Chamber Order, the stones required for the mausoleum were mined from the south of the Wei River and transported to Lishan via the Weihe River. The required stones have basically arrived at Lishan, and the construction has been completed. Nine times out of ten.”
I nodded. Then everyone reported on the materials, timber, civil construction, utensils, etc., and they were basically almost complete. However, for such a large-scale project, it still takes a long time between near completion and completion.
Seeing that everyone had finished reporting, I looked at Zhang Han and asked, "College Zuo, you mentioned in your report that it was difficult to transport the stone, which greatly reduced the progress of the project. Is this true?"
Zhang Han cupped his hands and said: "Your Highness, this is indeed the case. The weather is already cold now, but it has not yet reached the level where water can turn into ice. The wood is lost too much during the rolling process. It takes dozens of logs to roll a complete stone. Transported to the interior of the mausoleum. In addition, when the stone is transported from the quarrying ground to the ship and disembarked nearby, it is easy to cause the ship to sink, which greatly slows down the construction progress. Fortunately, the four walls, columns, and roof of the main body have been completed, but the ground masonry is slower. , I will send more manpower to transport the stone, so Your Highness does not need to worry too much."
I pondered for a while, then looked at the craftsmen on the right and asked, "You are all the top craftsmen in my country. I have a drawing here. I wonder if you can build it according to the drawing."
The leader was named Gong Shujin. He raised his body and raised his hands and said: "Your Highness, I dare not speak nonsense. Can you lend me the drawings for a look first?"
I picked up the pen on the desk, spread out a blank scroll, drew a schematic diagram of the fixed pulley, the movable pulley and the pulley block from memory, and beckoned: "Come closer."
Gongshujin stepped forward and took the drawing in my hand. He was a little confused and looked up at me with confusion: "Your Highness, I'm sorry for my stupidity, but I can't see what this is."
Zhang Han also took it and looked at it carefully for a long time, but he didn't understand what it was.
Then I called the craftsmen over and explained to them: "
Everyone has seen a windlass, a tool used to fetch water from wells. In fact, the principle of this thing is similar to that of a pulley, but it can have more uses. Its name is a pulley.
Please look at the first picture. The pattern above represents the wall or other places where the rope can be fixed. The circle on the wall represents the fixed pulley, which means a fixed pulley. The pattern below represents what we want to pull. Such as stone, wood, etc. The thin lines connecting the patterns below are ropes, and the other end of the rope is in the human hand.
Suppose we want to pull this stone from the bottom of the city wall to the top of the city wall. We can only stand on the city wall and pull it from bottom to top. But this is very dangerous. Once someone lets go, they are likely to be taken down from the city wall with ropes and stones. In addition, although the city wall is long, it is relatively narrow. If many people need to pull on it, they may not be able to stand on the wall.
If we use this tool, we can build a shelf on the city wall, fix the pulley on the shelf, tie one end to the stone, and wrap the other end around the pulley and throw it under the city wall, so that people can pull the stone up under the city wall. ,do you understand? "
Looking at everyone's thoughtful expressions, it is very similar to the way I was thinking hard when the teacher asked me "Do you understand?" in class. I asked Zhang Han to find a small piece of rope and a short piece of wood, and roughly demonstrated the working process of the pulley. Unexpectedly, Gong Shujin was the first to react: "Your Highness, this villain seems to have heard from my father that he attacked the Song Dynasty in Wei State. Some people have used this method before, but with all due respect, this method is not as labor-saving and convenient as directly pulling up the city wall."
Zhang Han frowned and was about to speak. I raised my hand to stop him and said, "You can speak freely, it's okay. I wonder who your father is?"
Gongshujin lowered his head sadly, then raised his head with a hint of pride: "Your Highness, the villain's father is unknown, but I am a descendant of Gongshuban."
I nodded and smiled: "No wonder, I just showed you the general principle. In fact, this piece of wood cannot be used directly like this. Instead, it needs to be processed into a disk shape, and grooves must be carved on the edge of the disk."
After that, I asked Zhang Han to fetch a piece of soil. I refused to do it for him. I took the soil and pinched out the rough shape of the pulley, and then said, "This is what the pulley looks like, but it needs to be made of stronger materials." , I don’t know how your iron smelting technology is, it’s best to use iron to make it.”
Then I explained to everyone the principles and usage of moving pulleys and pulley blocks. Gongshu Jin is still the one who understands slightly better among everyone, but he still doesn't quite understand.
Seeing that everyone was meditating, I put down the things in my hands and said to everyone: "You can take the drawings and models back and think about it slowly. If you have any questions, you can come to me at any time. I will stay here until the application time."
After hearing this, everyone thanked and left one by one.
I want to have a good chat with Zhang Han in the next time.
