"If you want to do a good job, you must first sharpen your tools. The method of mentioning soil here is very ingenious, I don't know who came up with it? ”

Su Song stood in front of the tripod on the side of the ditch to lift the soil, turned around, and admired again and again.

Du Zhongxiao said: "I saw that it was too difficult for the trenching workers to lift the soil from the inside, so it was really convenient to make this rack to lift the soil." ”

Su Song's eyes lit up: "What an ingenuity!" In these things, there are often surprises, rare, rare! ”

This is just a very ordinary tripod, with a common lifting pulley block, in fact, it is a big wheel. The difference is that the wheels of the wheels are equipped with ratchet devices to prevent them from reversing and falling heavy objects to hit people. It was Du Zhongxiao who made such a thing according to the manual lifting gourd in his previous life, and specially lifted the soil from the ditch. Really speaking, there is no safety in his front hand hoist, the rope on the roller will slip, and there is still a risk of heavy objects falling. However, in this era, it was not easy to make iron chains, and the cost was high, so I had to use this simple version.

This simple lifting device can be used not only on the construction site, but also on the wharf, and even in the factory. Du Zhongxiao really made some in the blacksmith shop in his spare time, ready to sell them elsewhere. At this time, don't think about any patent blockade, whether it is the current social situation or productivity, it is far from reaching. Only monopoly materials such as wine can be monopolized with the help of government means.

There are many such gizmos on the construction site. At the beginning, Du Zhongxiao used the knowledge of his previous life to make some small tools according to local conditions, and later formed a trend, and the workers used their wisdom together to do a lot. After that, Du Zhongxiao formulated a special reward system to mobilize everyone's enthusiasm.

This is how the Industrial Revolution began in history. In the beginning, there was a blank space, and a large number of people used their ingenuity to make various technological innovations and improvements. When it has a certain scale and slowly enters the early stage of industrial society, in order to maintain the profits of factories, society will use patents or various means to restrict and enter a new stage.

In Du Zhongxiao's previous life, everyone liked to talk about intellectual property rights the most, and they liked to say that their country did not protect intellectual property rights, because this made new technologies unprofitable. In fact, whether it is a patent-protected invention or some other systems in the industrial system, they all have their own stages of adaptation and their own development laws. At this time, as in this time, we are still far from the industrial society, everything can only revolve around the product, and there is neither the means of implementation nor the realistic possibility of protecting technology. Forcing it to do so will slow down the process of industrialization.

This is the problem faced by Du Zhongxiao, he knows how the first industrial countries in the history of the previous life started the industrial revolution, but how useful it is in this era, but he can't say how much. Whether it's patent protection, mercantilism, radical bloody primitive capitalism, sheep eating people, etc., it can be poison. Which is a tonic and which is a poison, you can't try everything, and you can't wake up until you're dying. For Du Zhongxiao, technical ones are always useful, and institutional reforms should be cautious.

Su Song was naturally interested in things like technology, and he was very interested in watching it along the way, asking Du Zhongxiao questions from time to time, and secretly wrote it down in his heart.

It wasn't until noon that I took a look at it. Su Song said: "If such a big ditch can be connected all the way to the Lianhe River, it should be navigable." At that time, it was almost no different from Jiangnan, and ships could reach it everywhere. ”

Du Zhongxiao smiled: "It's good." However, the water of the river is shallow, and navigation is not of great use. The most important thing is that this area grows food and recruits more people to come. The Central Plains is prosperous from the west, and it is not a blessing for the country to be desolate everywhere like it is now. ”

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

It is common for land reclamation to have a plan, but like Du Zhongxiao has done it in such detail, what are the main roads, how many villages, how many households, and how much land each household has, all of which have been marked out in advance, or Su Song feels novel.

After Du Zhongxiao finished speaking, Su Song asked: "I see that your map is marked in great detail, and the distance in the field is clear one by one, I don't know how to do it." ”

"Naturally, it is necessary to start by dividing the blocks first, and then select capable personnel to measure, and it is best to draw them one by one on the map. If you look at this picture, there are small grids drawn out of thin lines, and each small grid is a point, so you can calculate the distance and the number of acres, which is simple and clear. ”

Su Song nodded, looked at the irregular blocks on the map, and pointed and asked Du Zhongxiao how to calculate it.

On a whim, Du Zhongxiao picked up the pen and checked the area of each block on the map with Su Song. This is the content of plane geometry, and Su Song also dabbles in related knowledge, but he learns according to the book, which is far less systematic than what Du Zhongxiao learned in his previous life. Interested, the two of them were in high spirits.

At this moment, a public official came from afar and saluted in front of Du Zhongxiao: "Engaged, there is a letter, and the judge in the village sent it with a small one." If there is nothing to do, please go back to the village to discuss. ”

Du Zhongxiao took the letter and couldn't help but be stunned for a moment, unexpectedly it was Wang Anshi from Yangzhou who handed it over. Since Dengdi left Beijing, the two have exchanged letters through several letters. It has only been half a month since I last received a letter from Wang Anshi, and I don't know what he wrote to do again. And the official documents used are not a private matter. It's just that I can't think of what kind of business trip the two states can have when they are hundreds of miles apart.

Open the letter, it turned out that Yangzhou recently arrested a big thief named Song Sigong. This thief committed many crimes in the capital, and the thieves stolen a lot, and when they committed the crime again in Yangzhou, they were stolen and seized. After interrogation, the thief confessed that before going to Yangzhou, he had come to Bozhou and took refuge in Ma Meng. Because of his suspicion of Ma Meng, he set fire to the Buddha Nunnery and fled to Yu County. After meeting the contract, he killed three more people and went to Yangzhou.

At this time, the governor of Yangzhou was Su Song's father, Su Shen, who was unhappy because he was expelled from Beijing, and he was mostly handed over to Wang Anshi for signing the government. Wang Anshi interrogated Song Sigong and sent an official letter to Bozhou to verify whether Song Sigong's confession was true.

To Du Zhongxiao's surprise, Song Sigong not only recruited Ma Meng, but also recruited a state official Chai Jie level. What position this person holds in the state government and what affairs he is in charge of, Song Sigong can't say clearly. It is only said that he has traveled a lot and knows Ma Meng well. Ma Meng was interrogated many times, but the official surnamed Chai in the state government was not involved, so Du Zhongxiao couldn't help but pay special attention.

After thinking about it for a while, I was not familiar with the state yagong, and in addition to my personal retinue Chai Xin, I really couldn't remember any other surname Chai. Of course, Chai Xin is impossible, not to mention that he has always been by his side, and it is impossible to do such a thing with his position. has such a relationship, who still follows a new pusher to do errands. This firewood festival level, when there is someone else.

Put away the official documents, Du Zhongxiao asked the public who delivered the letter to reply first, and he would arrive later.

Sending the duke away, Du Zhongxiao said to Su Song: "Yangzhou moved over and said that a big thief was caught there, named Song Sigong." The guy had come here to take refuge in Ma'mon, but later found out that Ma'mon had bad intentions and set fire to it and fled. This matter coincides with Tan Erniang, who hanged herself a few days ago, and it is no different to think about it. That guy set fire here, burned an old nun to death, and killed three more people before fleeing to Yangzhou, which can be a thief. From his confession, he knew that the state government had a chaijie level and had been colluding with Ma Meng. Ma Mengfan committed crimes in the state city, which is mostly related to this firewood festival level. This matter is not small, let's go back to the village quickly! ”

After speaking, he thought for a while and said: "With the character of Chai Jie, the case of Tao Seventeen's family should be solved. If a few big cases can be recovered from this person, Tao Seventeen may still be saved. ”
