Deep in the Iron Supervisor, a small river flows out of the mountains. It is cut off by a dike in the middle of the two hills, becoming a small lake. The rainfall in this area is uneven in all seasons, with rivers roaring in the rainy season, and in the dry season in winter and spring, it becomes a trickle. This summer and autumn rainfall is particularly heavy. Although the river is not big, the cut out lake is rippling, filling the deep ditch between several surrounding hills.

This is the source of the forging power used by the iron supervisor now. All hydraulic machinery is driven by the water drawn out here. The terrain is used to dig canals to dig water, and a rotor is set up in the appropriate places, forming several processing centers in the iron supervisor.

The weather was clear that day, the nearby mountains were filled with golden mountains, and the level in the lake was quiet. Dozens of soldiers from the iron prison were replacing the sluice gate at the gate. Now iron is produced, so the wooden bucket doors in the past naturally had to be replaced and replaced with iron-packed ones.

Du Zhongxiao stood by the lake, watching the soldiers lift the wooden gate, remove the wooden gate, and replace it with a remade iron-packed gate. It is not easy to lift the gate. Several people pushed the winch and slowly lifted it. The new gate was lifted with spirals, replaced the old one and installed the new one.

In this era, screws were not easy to make bolts, and it was amazing that iron supervisors could produce roughly general studs.

Seeing that everything went well, Du Zhongxiao left the lake and saw that the weather was sunny and walked around. Soon, he arrived in front of a row of big houses by the lake and heard the sound inside, so he walked in.

This house is very tall. Su Song is surrounded by more than 20 people including Nie Mao and Tong Anlu, discussing the steam engine that was dismantled next to it. This machine made by Du Zhongxiao when he was in Yongcheng was improved many times over several years by Tao Shiqi and Su Song. Now it has only left the original large framework, and the specific structure inside has long been beyond recognition. This is an experimental machine. This time he went to the Iron Supervision Bureau and finally completed his mission.

A few days ago, roads were built everywhere, and the machine was equipped with two big stone mills and was carrying the road everywhere. This time, the two big stone mills were placed at the door, like a magical beast guarding the door. This machine is useless and has become a tool for teaching in the Iron Supervision.

Seeing Du Zhongxiao coming in, Su Song and everyone hurriedly saluted.

After sitting down in the middle seat, Du Zhongxiao said, "How? Everyone knows how this machine is constructed, right?"

Su Song said: "There are all smart people who have been carefully selected here. After spending these days, it has been clear."

Du Zhongxiao nodded and said, "The most important thing is to know the truth and the reason. Not only do you need to know the machine structure, but you also need to know what it means, why you need to burn coal, and how you can turn things around. What is the force coming out of this machine, what kind of character does it have, and how to use it. Get all of these and have a bright future."

Everyone said it was. After learning in recent months, they have selected talented in machinery. They are not craftsmen, but are the best ones who start with the most simple theory, go step by step, and then practice it personally. What they are studying here is mainly the principles and structure of machines, how to improve and how to use them. They really have to make parts and cooperate with skilled craftsmen.

After asking everyone about their situation these days, Du Zhongxiao stood up and looked at the machine that was dismantled.

Su Song is very organized in his work. His huge body draws small areas and has many small tables on it with the parts removed. There is a note in front of each part, with the name of the part written, where it is installed, and what is its use. Don’t underestimate the dozens of words on each note. Being able to fully understand them all represent a certain amount of knowledge.

Du Zhongxiao was a little unfamiliar with the specific structure and parts inside. Su Song and Tao Shiqi changed too much, and they named it again and were not the same system as what he learned before. Their names used a lot of words such as arrows, reviews, plates, yokes, etc., and the words such as shafts, wheels, rods, etc. that Du Zhongxiao was familiar with rarely appeared. This kind of thing cannot be forced, so Du Zhongxiao could only ask them to have some basis for naming, and naming them according to their functions to form a system.

Looking at these parts that are both familiar and unfamiliar, Du Zhongxiao sighed secretly. This machine has gradually changed from something that he is familiar with to things of this era. From real objects to names, they will be different from what he is familiar with, and they can only slowly adapt.

After reading it once, Du Zhongxiao sat down again and said, "You can disassemble this steam engine together, and I think you will reinstall it. I have become familiar with these days, so I have to find a way to make it lighter and better."

Everyone agreed.

Du Zhongxiao also said: "When I first made this machine, it was difficult to find good steel. I often used pig iron, which was both stupid and heavy. Now, iron monitoring is good steel, and it is also convenient to make it into various shapes. It should be much easier than before."

Looking at the brass piled on the ground next to it, Du Zhongxiao said again: "It is not easy to cut steel, so I have transported some copper for you. If you want to make any shape, you can use copper first. If it is really complicated and difficult to make, you can use copper."

Su Song said: "When using copper parts, you can only look at their function. If you really want to use them on a machine, you still have to make steel parts, otherwise how can you know if they can be used? Copper is still much worse than steel."

Du Zhongxiao nodded. The use of copper parts is to test the mechanical structure to see if it can meet the requirements of kinematics. If it is really used on machines, it also involves strength and hardness, and steel parts must be used. However, in this era, it is impossible to accurately calculate the strength, so it can only be tried bit by bit based on experience. The contents of the booklet he compiled himself can also be used in kinematics. For deeper knowledge, we can only rely on these people to explore.

What Du Zhongxiao can provide are some basic mechanical structures, such as cranks, gears, ratchets, flywheels and other mature mechanisms. The basic principles are explained clearly, and it depends on the understanding of each person and how to combine them. As for combining them with reality, Du Zhongxiao has no energy to go deeper. At this level of steam engines, Du Zhongxiao is actually not easy to intervene. After learning, these people have formed their own thinking methods. In the end, the practical machines they made can of course be similar to those in later generations, but the process is very different.

Traditional Chinese machinery, such as the bronze chariots and horses of the Qin and Han dynasties, later astronomical instruments, and even various agricultural tools, were used to make particularly complex systems, which was not the same as later generations. Du Zhongxiao could already see that many of them were clever and exquisite, and they were not the same as their own simplicity and roughness. Among these people, many of them were recruited scholars, and the taste of scholars was really hard to describe.

After discussing some general frameworks, such as power system, steam pressure detection and control system, and transmission system, Du Zhongxiao stopped and asked Su Song to come out together. The reason why Su Song was asked here was the current machine design, which inexplicably brought the literati style. Not only did he pursue exquisiteness, but some also had poetic and picturesque style. When others introduced it, Du Zhongxiao was stunned.

This is nothing strange. Everything must have its own characteristics of the times. For example, the early European machines often had exquisite patterns, which was the aesthetic taste of others. The same is true for this era. The machines made must be exquisite and simple. This is the aesthetic of the Song Dynasty and cannot be forcibly removed. When they become popular and truly applied to the public, these fancy things will naturally disappear slowly.

After leaving the room, Du Zhongxiao shook his head slightly. At this time, the people he recruited slowly grew up, everything would become a system, and his personal color would gradually fade. When they really made practical machines, Du Zhongxiao might also have to adapt to this system.

Sitting down by the lake and looking at the rippling lake surface, Du Zhongxiao said: "In a few months, I didn't expect these people to learn and think of ways to make new things by themselves. The things we have accumulated over the past few years are hopeful to be carried forward."

Su Song said: "What's so strange about this? These people were carefully selected from several states, learning and doing things, and learning from each other. It's not surprising that they have achieved today's achievements. According to my estimate, in a few months, the machines they made will be far from what they were."

Du Zhongxiao thought about it and found that it was normal. The scope of recruitment of the Iron Supervision covers most prefectures and counties on Jingxi Road. With such an area, such population size, and such historical traditions, Europe is afraid that few countries can compare with it during the Industrial Revolution. It is not surprising that the selected talents can do anything. It is normal to lead the way in the general direction and not take detours.

Du Zhongxiao and Su Song have the advantage of being in the general direction and ideas. Some of the real meticulous aspects cannot compare to these young people who often take action at the bottom. They have no ideological burden and dare to think and do it, so they cannot underestimate them.

Du Zhongxiao said: "The world is all about the principles. This time, we need to build this machine not only to make what can be used, but also to summarize the principles. For example, how to turn from front to back to rotate the wheel. Is there any other way besides the methods we use now? For example, if the operation is unstable, and a large iron wheel is used as a flywheel, it will stabilize. Such things are summarized into a booklet like us, which is even more important."

Su Song nodded: "I understand. I understand that today's Iron Supervisor starts with a few booklets. Everything is the most difficult to start with. One person makes something, and one cannot teach others in the booklet, and the other person does it again, which will naturally be exhausting."
