Zhang Han looked shocked at me, and roared angrily: "Bold, you dare to talk nonsense!" Someone, drag him out of the cane and kill him! ”

Gong Jin and He Xian were so frightened that they almost sat on the ground. I hurriedly stopped: "Zhang Han, what is this for?" ”

Zhang Han said: "Your Highness, this person dares to speak wildly, His Highness has brought such a tool to Lishan, how dare he compete with His Highness for fame!" ”

I waved my hand to let the soldiers who came in retreat, and then said to He Xian: "He Xian, don't be afraid, you said that you know this thing, can you tell me in detail?" ”

He Xian hurriedly bowed deeply and explained: "Your Highness, the villain's sin deserves death. The pulley villain drawn by His Royal Highness has indeed been seen in the "Book of Ink", but among them, only the first fixed pulley painted by His Royal Highness is fixed, but there is no use of the latter two, especially the pulley is fixed on the stone being transported.

After the experiment between the villain and the owner of the public transport workshop, it was found that the pulley recorded in the "Book of Ink" is consistent with the first fixed pulley, which is only made of wood, and can not save manpower, and the latter two greatly save the manpower of transportation. ”

I was lost for a while after hearing this, I thought that He Xian had also crossed over, so that at least we could find a way to go back together, no matter how bad we were, we had a chat with a companion, which is like now, I was locked up in Xianyang Palace all day long, and I didn't even look at what this world was like carefully, and no one could talk.

When I came back to my senses, I asked again: "You said that there is a method of making and using pulleys in the Book of Ink, is this true?" ”

This time, the prince replied: "Your Highness, it is true. The villain is not as familiar with the "Book of Ink" as He Xian, so he did not find it, but after the villain checked it after going back, there is indeed a description of the use of a slug and a pulley to help lift heavy objects, and the is the pulley drawn by His Royal Highness. ”

The wisdom of the ancients is really not to be underestimated, even in the Warring States period thought of using pulleys to help lift heavy objects, the same era Archimedes is known as the father of mechanics, I don't know the Mohist research on mechanics to what extent. ’

With this in mind, I asked Gong Chuan Jin, "Can you lend me a view of the Book of Ink?" ”

Before Gong Jin could reply, Zhang Han took the lead and said: "Your Highness, the "Book of Ink" is written by the Mo family, and there should be a collection of books in the doctor's palace, and they do not have a relatively complete "Book of Ink" in their hands. ”

"Your Highness, what Colonel Zuo said is very true. Therefore, the number of words in the book is more, the bamboo slips made are bulky, and the villain does not have the conditions to be suitable for collecting books, there are only fragments in his hands, which are more scattered, and His Royal Highness can go to the Doctor's Palace to read. Gong said cautiously.

The number of words in a family's work is bound to be a lot, and with the current writing conditions, it will indeed be a large pile of bamboo slips. I reacted and smiled: "It's me who is anxious and wants to see this strange book, you are right to remind me." ”

Then I asked about iron smelting.

Through Zhang Han's narration, I have a general understanding of the development of iron-smelting technology in the Qin Dynasty.

Originally, in the Qin Dynasty, the iron smelting technology has been relatively developed, but the technology of softening iron (commonly known as wrought iron) has not been widely used because of time-consuming and labor-intensive and low output, mainly by melting the iron and pouring it into the mold to pour and form, also known as pig iron, mainly white iron.

The characteristics of white iron are strong rigidity but relatively brittle, the advantage is wear-resistant, but it cannot be forged, so in the Qin Dynasty, iron was mainly used as the production of agricultural handicraft tools, such as iron rake, iron antimony, iron sickle, iron rake, iron shovel, iron hoe, iron plow, etc., can not become a weapon, a few world-famous sharp weapons are wrought iron created by craftsmen constantly repeating experiments.

However, there are many situations in which iron can react with other substances, and because of the lack of information, blacksmiths cannot communicate with each other, and even if someone occasionally creates wrought iron that can be used, there is no guarantee of success, and swordsmithing has become a relatively mysterious profession.

Before the Qin Dynasty unified the Six Kingdoms, several well-known iron-smelting families, such as the Zhuo family, the Cheng family, etc., were all concentrated in a certain place for management after Qin Shi Huang unified the Six Kingdoms, and the government set up the post of chief iron official, and the iron-smelting industry was brought under the official camp. 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 the productive forces, the law that the relations of production must be suited to the development of the productive forces, and the contradiction between the advanced social system and the backward productive forces...... I cannot help but think of these well-known social theories of later generations.

Even if I became the second emperor of Qin and had the technology and production methods that the Qin Dynasty people could not have, if I forcibly made some changes without considering the backward social system of the Qin Dynasty, I am afraid that my fate would be even more miserable than that of Wang Mang, after all, I am not the founding emperor. The development of productive forces and the matching of the corresponding social system are indispensable.

After listening to the three of them, I said to Zhang Han: "The pulley matter will be handed over 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 slowly popularized to ordinary people's homes in the future." ”

Zhang Han saluted and said yes.

Then I said to Gong Yi and He Xian: "Although the Mo family and the Gong Lose family have gradually declined in recent years, I know what the skill of the mechanism you have can bring, and I have other ideas in the future, and I will send someone to tell you that you can ponder together, provided that it does not affect the construction of the Lishan Mausoleum." He Xian can participate in the construction of the Lishan Mausoleum. ”

The two of them were overjoyed, it was not easy to get my support, let alone the fact that I was able to 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 the people of the hundreds of schools of thought still insist on inheriting their own doctrines. The Renaissance in the West brought them great social progress and scientific and technological development, but the contention of a hundred schools of thought in China has been silent for 2,000 years after its glory, which has to be regretted.

Everything is settled, and it's time to go back to Xianyang.

When the three of them took me out of the government office and was about to board the carriage, the sky was full of snowflakes.

The ancients often said that in the year of Ruixue Zhaofeng, I have liked snow since I was a child, occasionally feeling the heroic spirit of "thousands of miles of ice, thousands of miles of snow drifting", occasionally imagining the silence of "lonely boats, fishing alone in the cold river and snow", and also imagining "Chaimen smells the dog barking, and the wind and snow return to the people at night", and I sit comfortably in the warm house.

It's just that I don't know that the people who built the Lishan Mausoleum, built the Afang Palace, and built the Great Wall of Shangjun, as well as the thousands of people from all over Daqin, how many of them can survive this biting cold winter and live until next spring.

Of course, there is also the First Emperor who has already made it to Nanjun......

"What a good Chinese people, you must treat them well." I said softly. I don't know if I said it to Zhang Han or to myself.
