The face is like a heavy jujube, a black horse, a red blood knife, two red and one black, which forms a very strong intuitive impression of Wei Yan, in the detailed report, Wei Yan has been in the army of 20,000, marching towards Huaishui. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

It was September, and the autumn was high and the horses were fat, and it was the time to use the soldiers.

Before Cao Cao raised his troops, it was determined that Liu Bei would go to attack Yuan Shu, and Lu Bu would inevitably attack Xuzhou, Liu Bei and Lu Bu would not be able to attack Xu Du, Wei Yan's army was going to Huainan, and now he could send troops to Nanyang County with confidence.

Cao Cao wanted to take advantage of Wei Yan's absence to defeat Zhang Xiu and occupy Wancheng, once Cao's army occupied Wancheng, it would form a scissors shape with the north of Runan, and Wei Yan's forces were between scissors.

This time, Cao Cao brought all the 50,000 horses he could bring with him, and slaughtered Wancheng.

Cao Ang, Cao Anmin, and Dian Wei were all by his side, but Yu Ban and Shadow Horse were missing.

……

At this time, on the south bank of Huaishui, Zhang Xun stared at the riverbed: "Why has the water level of Huaishui dropped so much?" ”

Lei Bo said: "There is a big drought everywhere in Huainan, and the water level of Huaishui is a little lower, what's so strange?" ”

Zhang Xun shook his head: "There is no drought in the upper reaches of Huaishui, so it is said that the water level will not be lowered so much?" ”

At this time, the scout reported: "General Zhang, many villages in the upper reaches have diverted the flow of Huaishui, so the water level has dropped!" ”

Zhang Xun was relieved: "I see, then cross the river!" ”

Zhang Xun, Lei Bo, and Chen Lan's 60,000 horses crossed the river together, because the water level had become very shallow, and they could not walk.

……

At this time, a caravan of more than fifty people set off from Yiyang New Town and headed for Chaoyang County.

This time, they only went to Wancheng to sell one thing, which was a rare thing that people had never heard of and never seen in this era, the substitute cultivator, also known as the manpower cultivator.

It turned out that two months ago, Wei Yan found that there were more and more famous homeless people who came to defect, but there was a problem that came into being, there was a shortage of ploughing cattle, and dozens of homeless people could only get one ploughing ox, so they had to pull plows to plough the land, which was very inefficient.

Wei Yan had no way to solve this problem, so he asked Ma Jun, Ma Jun couldn't think of it, and asked Huang Yueying, and Huang Yueying couldn't think of a solution.

There was really no way, so Wei Yan asked Kongkong: "Is there any machine that can replace the ploughing cattle?" ”

"Yes, tractor!"

Wei Yan said angrily: "What I asked is, is there any machine that can be realized in this era?" ”

Kongkongdao: "This can be had!"

In the twenty-third year of Jiajing of the Ming Dynasty, Ouyang Bijin, who was the governor of Yunyang at the time, encountered a very tricky incident. Due to the local rinderpest, the ploughing cattle almost died, and the people had to use people to pull plows to plough the land, which was miserable. Ouyang Bijin couldn't sleep and eat peacefully for this, and he didn't think about tea and dinner. In the midst of depression, I remembered the reels of Anfu Tishui in my hometown of Jiangxi, and found the sketch of the manpower cultivator made by Tang Wangyi from the data, and immediately imitated it by myself, and continuously improved it in practice, creating the first manpower cultivator in China by twisting the rope through the pulley to pull the plough, and inventing the first manpower cultivator in China.

Later, in the seventh year of the Tomorrow Apocalypse, Wang Zheng wrote "Diagram of Cultivating on Behalf of Farming", made a detailed description of the shape and structural details of the cultivator, and there are attached drawings, from which it is known that the cultivator frame is a herringbone wooden frame set up at both ends of the field respectively, each frame is equipped with a roller, wrapped with a rope in the middle of the roller, a small iron ring is knotted in the middle of the rope, the ring and the plough are dragged on the hook, free to take off, the two ends of the roller are installed on the cross of the pegwood, the plough acts by itself, when using three people cooperate, one person at each end of each hand to pull each other, one person in the middle of the plow, one person with one hand, That's enough for two cows.

I can give you this picture, but it costs 5000 credits! ”

Wei Yan had no impression of this thing at all, so he simply exchanged 5,000 points for a drawing and handed it over to Ma Jun and Huang Yueying to try produce.

Ma Jun won this victory, and the rapid mass production of his trial production was put out, which solved the problem of a large number of displaced people, and also began to market the Han Dynasty in various places where there was a shortage of cultivated cattle.

The caravan came to Chaoyang County with parts that could be disassembled and interchangeable, and came to the dock fort in Ganning.

They put together something else, something else very threatening.

On the way from Chaoyang County to Wancheng, they encountered some interrogation by some Western Liang soldiers, who assembled the manpower cultivator in front of those Western Liang soldiers, and then bribed them to pass.

There are a lot of caravans like this, and they have successively called a lot of interesting things to the people around Wancheng.

It's not that it's only grown so much recently, it's just that there have been so many caravans, nothing like usual, just a lot more strange things.

For example, completely transparent and bright glass without any color is called glass by the caravan.

Colored glass, naturally different from glass, colored glass refers to the use of various colors of artificial crystal as raw materials, using the ancient bronze wax casting method of high temperature dewaxing into crystal works, its color is colorful, beautiful; Its quality is crystal clear and dazzling. The history of manufacturing glaze in ancient times can be traced back to the Western Zhou Dynasty, when the original materials for making glaze were obtained from the by-products produced during bronze casting, which were refined and processed and then made into glaze. There are many colors of glaze, and the ancients also called it "five-color stone". In the Han Dynasty, the production level of glaze has been quite mature, but the smelting technology is in the hands of the royal family and nobles, and it has been kept secret.

However, at this time, there were already glass products, and the Eastern Han Dynasty's "Xijing Miscellaneous Records" cloud: "Zhao Feiyan's daughter's brother lives in Zhaoyang Palace...... The windows are mostly green glass, and they are all shining, and the hair cannot be hidden. People can see the hair of the people in the hall through the green glass installed in the window, and it is impossible for any green natural material in nature to "shine" in this way, and the green glass here obviously refers to the artificially made green glass.

The biggest problem of glass products in this era is that there are many impurities, resulting in color, and what Ma Jun needs to solve is actually to pick out the impurities to ensure transparency and light transmittance.

The function of transparent glass is naturally not only to make telescopes, but also to make microscopes, mirrors, glasses, and windows.

Especially myopia glasses, intellectuals in this era, many people study hard under very poor light conditions, many people have eye diseases, that is, myopia, if they can make glasses with the right prescription, they are willing to buy glasses that are more expensive than later generations.

The caravans looked the same in number, but the people inside were all different.

When Xiliang saw the benefit fee, he didn't think deeply.

Jia Xu received the following report, but there was no change from the original, so he did not feel at ease.

……

A big drama is about to begin.
