"If you want to do something well, you must first sharpen your tools. The method of bringing up soil here is very clever. I wonder who came up with it?"

Su Song stood in front of the tripod that was lifting soil by the big ditch, and turned around, and exclaimed repeatedly.

Du Zhongxiao said: "I saw that it was too difficult for the workers who dug the trench to lift the soil from inside. It was really convenient to carry the soil through this rack."

Su Song's eyes lit up: "What a clever idea! When I was surprised, there are often unexpected things in these things, which are rare and rare!"

This is just a very ordinary tripod, equipped with a common lifting pulley set, which is actually a big wheel. The difference is that the wheel of the wheel is equipped with a ratchet device to prevent backwards and heavy objects from falling and hitting people. Du Zhongxiao made such a thing out according to the manual lifting hoist in his previous life, and specially lifted soil from the ditch. To be honest, it is not as safe as the manual hoist in front of him. The rope on the wheel will slip and there is still a risk of heavy objects falling. However, it is not easy to make iron chains in this era and the cost is high, so I have to use this simple version.

This simple lifting device can not only be used on construction sites, but also on docks, and can even be used in factories. Du Zhongxiao really made some blacksmith shops in his spare time and prepared to sell them to other places. At this time, don’t think about patent blockade, whether it is the current social situation or productivity, it is far from reaching. Only specialized materials like wine can monopolize the business with the help of government means.

There were many such small inventions on the construction site. At first, Du Zhongxiao used his knowledge in his previous life to make some gadgets according to local conditions. Later, a trend was formed, and the workers used their wisdom to make a lot of them. Later, Du Zhongxiao formulated a special reward system to mobilize everyone's enthusiasm.

This is how the industrial revolution began in history. At the beginning, it was a blank space. A large number of people used their intelligence and made various technological innovations and improvements. When they reached a certain scale, they slowly entered the early stage of industrial society. In order to maintain factory profits, society would use patents or various means to restrict them and enter a new stage.

In Du Zhongxiao's past life, everyone likes to talk about intellectual property rights the most, and likes to say that their country does not protect intellectual property rights, because it makes new technologies unprofitable. In fact, whether it is patent protection inventions or other systems in the industrial system, they have their own adaptation stages and their own development laws. Just like at this time, it is still far from the industrial society, and everything can only revolve around products. There is no means to implement protection technology, nor is there a realistic possibility. Forcing it will slow down the process of industrialization.

This is the problem facing Du Zhongxiao. He knew how the industrial countries that were first launched in the history of his previous life began the industrial revolution, but they were somewhat useful in this era, but they couldn't explain it clearly. Whether it was patent protection, mercantilism, radical bloody primitive capitalism, sheep eating people, they might be poisons. Which ones are tonics and which are poisons, they can't try everything, and only wake up when they are dying. For Du Zhongxiao, technical aspects are always useful, and institutional reforms must be very cautious.

Su Song Tianran was interested in technology and was very excited along the way. He asked Du Zhongxiao questions from time to time and secretly wrote them down in his heart.

It was not until noon that I took a quick look. Su Song said: "If such a big ditch can be connected to Huan River, it will be open to navigation. At that time, it will be like Jiangnan, and ships can be connected to all directions."

Du Zhongxiao smiled and said, "It's good. However, the Huan River is shallow and navigation is useless. The most important thing is that this area produces grain and recruits more households to come. The Central Plains are prosperous from the west, and are desolate everywhere like now, which is not a blessing for the country."

The two returned to the settlement of the land reclamation personnel, and Du Zhongxiao pointed to the planning map of this area to explain to Su Song.

It is common for land reclamation to have a plan, but like Du Zhongxiao did it so meticulously, what are the main roads, how many villages, how many households, and how much land each household is about, are all marked out in advance, and Su Song still finds it novel.

After Du Zhongxiao said that, Su Song asked, "I see what is marked on your picture in detail, the distance and distance in the ground are clear, and I don't know how to do it."

"Of course, we should first divide the blocks first, and then select the capable personnel to measure it. It is best to draw them one by one on the picture. Look at this picture, there are small grids drawn by thin lines, and each grid is one minute. From this, we can calculate the distance and the number of acres, which is simple and clear."

Su Song nodded, looking at the blocks on the picture that were not regular, and pointed at how Du Zhongxiao calculated it.

Du Zhongxiao was on a whim and picked up his pen and checked the area of ​​each block on the diagram with Su Song. This is the content of plane geometry. Su Song also dabbled in related knowledge, but he just learned from the calculation of books. It was far less systematic than Du Zhongxiao's previous life. When he was excited, the two of them were very excited.

At this moment, a public official came from afar and saluted in front of Du Zhongxiao: "I have a letter from my business, and the judge in the village brought him with me. If there is nothing wrong, please go back to the village to discuss the matter."

Du Zhongxiao received the letter and was stunned for a moment. Unexpectedly, it was Wang Anshi from Yangzhou who handed it over. Since he was promoted to the post, he left Beijing, and the two of them had several letters, which were nothing more than human relations. It was only half a month before he received Wang Anshi's letter last time. I wonder what he wrote to do. And the official documents he used were not private matters. But I couldn't remember that the two states were hundreds of miles apart, so what could there be for business operations.

When I opened the letter, I found that Yangzhou had recently arrested a thief named Song Sigong. This thief committed many crimes in the capital, and there were many stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen stolen

At this time, the magistrate of Yangzhou was Su Song's father Su Shen. He felt unfair because he was excluded from the capital. He often submitted the government affairs to the verdict of Wang Anshi. Wang Anshi had tried the Sigong of Song and sent a document to Bozhou to verify whether Song Sigong's confession was true.

What surprised Du Zhongxiao was that Song Sigong not only recruited Ma Meng, but also recruited Chai Jie-level, a public official in the state. Song Sigong couldn't explain clearly any position in the state yamen and what affairs he was in charge of. He only said that he had a wide range of friendship and knew Ma Meng well. After interrogating Ma Meng many times, he did not involve the public official surnamed Chai in the state yamen, so Du Zhongxiao could not help but pay special attention.

After thinking for a while, I was not familiar with the officials of the state yamen. Apart from my personal entourage, I really couldn't remember which other surname was Chai. Chai Xin was of course impossible. Not to mention that he had been with him, it was impossible for him to do such things with his position. If it had such a relationship, who would have followed a new promoter to do errands? At this Chai Jie level, there is someone else.

After putting away the official documents, Du Zhongxiao asked the official who delivered the letter to go back first and then he arrived.

After seeing off the duke, Du Zhongxiao said to Su Song: "Yangzhou moved over and said that a thief was caught there, named Song Sigong. The guy had come here to surrender to Ma Meng, but later he found that Ma Meng had bad intentions and fled the fire. This matter was consistent with Tan Erniang who hanged himself a few days ago. I think it was OK. The guy set the fire here, burned an old nun to death, and killed three more people before he fled to Yangzhou. It was a thief. From his confession, he knew that there was a Chaijie level in the state yamen and had been colluding with Ma Meng. Ma Mengfan committed an incident in the state city, which was mostly related to this Chaijie level. This matter is not small, so let's go back to the village quickly!"
