Zhang Han saw my expression of shock and roared angrily: "How dare you talk nonsense! Someone, drag him out and kill him!"
Gongshu Jin and He Xian were so frightened that their legs trembled and they almost collapsed on the ground. I quickly stopped him and said, "Zhang Han, what are you doing?"
Zhang Han said: "Your Highness, this person dares to speak arrogantly. Your Highness has brought such a tool to Lishan. How dare he compete with His Highness for fame!"
I waved the soldiers who came in to retreat, and then said to He Xian: "He Xian, don't be afraid. You said you know this thing, can you tell me in detail?"
He Xian hurriedly bowed deeply and explained: "Your Highness, this villain deserves to die. The villain with the pulley that your Highness drew has indeed been seen in the "Mo Jing", but it only has the first fixed pulley that your Highness drew. , but there is no usage method of the latter two, especially fixing the pulley on the transported stone.
After the villain and the owner of Gongshu Square experimented, they found that the pulleys recorded in the "Mo Jing" that were consistent with the first fixed pulley were only made of wood and could not save manpower. The latter two greatly saved the manpower of transportation. It's the villain who didn't make it clear. Please punish me, Your Highness. "
I felt a little disappointed after hearing this. I thought that He Xian had also traveled through time, so that we could at least find a way to go back together. Even if it didn't work, we would still have someone to chat with. It's not like now, being locked up in Xianyang Palace all day long, without access to anything in this world. I haven't looked at it carefully, and no one can talk about it.
After coming back to my senses, I asked again: "You said that the "Mo Jing" actually contains instructions for making and using pulleys. Is this true?"
This time Gongshu Jin replied: "Your Highness, this is indeed the case. I am not as familiar with the "Mo Jing" as He Xian, so I didn't find it. However, after I went back and looked it up, I found that the book did mention the use of pulleys and pulleys. to help lift heavy objects, one of which is the pulley drawn by His Highness."
'The wisdom of the ancients should not be underestimated. They actually thought of using pulleys to help lift heavy objects during the Warring States Period. Archimedes at the same time was called the father of mechanics. I don't know to what extent the Mohist study of mechanics had reached. '
With this thought in my mind, I asked Gongshu Jindao: "Can I have a look at the Mo Jing?"
Before Gongshu Jin could reply, Zhang Han took the lead and said: "Your Highness, the Mohist Classic was written by the Mohist family. There should be books in the doctor's palace, but they do not have a relatively complete Mohist Classic in their hands."
"Your Highness, what Zuo Xiaoling said is true. Therefore, the number of words in the book is large, the bamboo slips made of it are heavy, and the villain is not suitable for collecting books. He only has fragments in his hands, which are relatively scattered. Your Highness can go to the Doctor's Palace to view them. "Gongshu Jin said carefully.
A family's work must contain a lot of words. Given the current writing conditions, it would indeed be a large pile of bamboo slips. I reacted, smiled and said, "I was impatient and wanted to read this wonderful book. You were right to remind me."
Then I asked about iron smelting.
Through Zhang Han's narration, I roughly understood the development of iron smelting technology in the Qin Dynasty.
It turns out that iron smelting technology was relatively developed during the Qin Dynasty, but the technology of softened iron (commonly known as wrought iron) has not been widely used because it is time-consuming, labor-intensive and has low output. It is mainly formed by melting iron and pouring it into molds, which is also called wrought iron. It is pig iron, mainly white iron.
The characteristic of white iron is that it is strong but relatively brittle. Its advantage is that it is wear-resistant, but it cannot be forged. Therefore, in the Qin Dynasty, iron was mainly used to make agricultural handicraft tools, such as iron shovels, iron antimony, iron sickles, iron shovels, and iron shovels. Iron hoes, iron plows, etc. cannot be used as weapons. A few world-famous sharp weapons are wrought iron made through repeated experiments by craftsmen.
However, there are many situations where iron can react with other substances, and due to the lack of information, blacksmiths cannot communicate with each other. Even if someone occasionally forges usable wrought iron, there is no guarantee of success every time. The swordsmith has become a relatively mysterious person. Profession.
Several well-known iron smelting families before the Qin Dynasty unified the six kingdoms, such as the Zhuo family, the Cheng family, etc., were all centralized in a certain place for management after Qin Shihuang unified the six kingdoms, and the government set up a chief iron officer. In this position, the iron smelting industry was brought back to the government. Despite this, due to the fact that charcoal was still mainly used to smelt iron at this time, the cost was relatively high, and the output of iron was not very high.
'Alas, the development of history requires the development of productive forces. Production relations must conform to the laws of the development of productive forces. There are conflicts between advanced social systems and backward productive forces...' I couldn't help but think of these familiar social theories of later generations.
Even if I become the second emperor of Qin and have technology and production methods that the people of the Qin Dynasty cannot have, if I do not consider the backward social system of the Qin Dynasty and force some changes, I am afraid that my end will be even more miserable than Wang Mang. After all, I am not the founding emperor. . Developing productive forces and matching corresponding social systems are indispensable.
After listening to the three people's stories, I said to Zhang Han: "I'll leave the pulley matter to you. If the experiment is successful, it can be promoted to other projects under construction as soon as possible, and it can also be gradually spread to ordinary people's homes in the future."
Zhang Han saluted and said yes.
Then I said to Gongshu Jin and He Xian: "Although the Mohist school and Gongshu family have gradually declined in recent years, I know what your organ skills can bring. I will send someone to tell you if I have other ideas in the future. You can think about it together, provided that it does not affect the construction of Lishan Mausoleum. He Xian can participate in the construction of Lishan Mausoleum."
The two of them were overjoyed. It was not easy to get my support, let alone that I could bring them something new in the art of mechanism. The scene of a hundred schools of thought contending has gradually subsided with the unification of the world, and people of various schools of thought still insist on passing on their own doctrines. The Renaissance in the West has brought them great social progress and technological development, but China's Hundred Schools of Thought has been silent for two thousand years after its glory. This has to be regretted.
With everything settled, it was time to return to Xianyang.
The three of them sent me out of the official office, and when I was about to board the carriage, snowflakes started to fall in the sky.
The ancients often said that auspicious snow heralds a good year. I have loved snowy days since I was a child. Sometimes I feel the heroic spirit of "thousands of miles of ice and thousands of miles of snow drifting", and sometimes I imagine the "lonely boat and coir raincoat, fishing alone in the snow in the cold river". In silence, I will also think about "hearing dogs barking at the firewood gate, returning home on a snowy night", and I feel comfortable sitting in a warm house with the stove.
I just don’t know how many of the civilians who built the Lishan Mausoleum, the Afang Palace, and the Great Wall of Shangjun, as well as the tens of millions of people across the Qin Dynasty, can survive this biting winter and live until next spring when the flowers bloom.
Of course, there is also the First Emperor who has already reached Nanjun...
"What a wonderful Chinese people, we must treat them well." I said softly. I don't know whether I said it to Zhang Han or myself.
