Before the autumn harvest, with a rare free time, Zou Yu's energy turned to the other side!

The massive use of waterwheels has changed a lot of things, but this is only a very rudimentary mechanical application!

If you want to use machinery better, the only way is the steam engine, which is simply not possible now! Not to mention the principle, even the skill is not up to standard, and there is sealing, if it is just an ordinary object, it can also be sealed with fish fat, etc., but the steam engine is a sports equipment, which will produce a lot of heat, and rubber must be used!

Eucommia gum can also be done, but the number of eucommia is too small, it is difficult to collect, if you really want to make a steam engine by pure hand, refine eucommia gum, and not to say whether it is successful or not, it is time, and it takes a long time!

Because Zou Yu just mentioned it to Brother Yan Lide, you can consider it when you have time. The most important energy is how to improve and use the existing equipment, especially the use of water conservancy equipment!

Yan Lide researches weapons, such as catapults, arrow towers, and crossbow arrows; And Yan Liben studies civil use, and the most at present is the pumping of waterwheels and the grinding of waterwheels!

In the north, it is customary to eat pasta, and the main food is wheat, so every household basically has a mill, even if they don't have it, their neighbors must have it; After a few days, the flour will be grinded.

This flour grinding is not too easy, people must drive the stone mill, only large families, or well-off families, can have livestock grinding.

Now because of the establishment of collective villages, it is logical that every village has built a water-powered mill! Such a convenient thing for the people is of course well received by the people.

In addition to irrigation and mills, the most established waterwheels are only mines and workshops! The mining area uses water wheels, mainly hammering, to knock large pieces of ore into small pieces; After all, the biggest advantage of hydraulic drive is that it can be forged non-stop.

"At present, 500 water wheels have been installed in the three major mining areas of Liaodong, Liaoxi, Jinyang! At present, the coal produced can reach 300,000 stone per month, which is barely enough for use in various places; Cotton, that is, the white stack seed removal machine, has been successfully developed and is currently being produced in large quantities.

As for the problem of slow operation of waterwheel equipment, the craftsman supervisor has experimented, as long as the number of gears is increased and the size ratio is adjusted, this problem can be solved, but the service life will be shortened. Yan Liben said proudly at the summary meeting.

Originally, Yan Lide and Yan Liben liked calligraphy and painting more, but the extensive use of hydraulic equipment suddenly provided them with new passion.

"Liaodong Workshop, because of the use of hydraulic equipment, steel knives and armor, the quality is higher, and the barrier knives made are thinner; At present, it can produce 1,000 obstacle knives, 2,000 horizontal knives, and 800 armor of various types every month! Yan Lide then reported.

"Not bad! We are very satisfied with the current development, but we can't rest on our laurels! First of all, let's talk about the production of equipment in Liaodong, the cavalry in the past, ordinary soldiers, are mainly iron horse lances! Change to a long gun in the future! With one zhang five as the standard, the gun body is one zhang long, and the blade is changed to a Mitsubishi thorn! Zou Yu nodded and said, handing Yan Lide a drawing.

The blade of the gun was changed to a Mitsubishi thorn, which was not only easier to pierce, but also could not be saved.

Cavalry charge, no other action is required, just stab with this extra-long spear, as for the body of the spear, it is iron-clad wood, which is both light and hard!

"The subordinate obeys!" Yan Lide looked at the drawings and replied. He only looks at the process, as for whether it is practical or not, he believes that Zou Yu knows better than him.

"There will always be casualties in close combat, so in terms of equipment, we should study how to improve the crossbow arrows! We need to destroy the enemy as long as possible and reduce our own casualties! Zou Yu reminded.

"Xia Guan understands!" Yan Lide nodded vigorously and said. He now became more and more fond of improving weapons, especially with all-metal weapons, there was always a feeling of blood boiling.

If Zou Yu knew his thoughts, he would definitely tell him that this is the true nature of a man! Anyone can feel this way, even if they hold a kitchen knife, they have the urge to swing it twice.

"Although coal can be burned, it still has a very pungent taste, and how to improve the firepower, I hope that the craftsman will be the next research direction!" Zou Yu continued.

"The subordinate obeys!" Yan Liben immediately recorded what Zou Yu said in his notebook, then raised his head and continued:

"Lord Wang, you ordered the craftsman to be the supervisor to select useful talents and expand the scale of technical personnel, and the lower officials specially invited three masters to come to help!"

"Hurry up, please!" Zou Yu was overjoyed and hurriedly said.

After a while, Yan Liben personally brought three people in.

"See the prince!"

"Ladies and gentlemen, excuse me! Yan Shilang, quickly introduce me. Zou Yu stepped forward to help the three people.

"These two are the former Ministry of Industry Shangshu, the son of Gongyu Wenkai of Anping County, and the doctor of the Scattered Dynasty! Yuwen Rutong, Yuwen Wen. They have a family history, and they are even more above me and my brother in terms of palace and city construction! It's just that the court has not been able to pay attention to it, and the prince is eager to seek talent, so the lower officials specially arranged for someone to invite them. Yan Liben introduced with a smile.

"But Yuwenkai, who built Daxing and Luoyang, Master Yuwen!" Zou Yu asked in surprise.

After seeing the grandeur of Daxing City, I deliberately went to learn about it, and knew that Yu Wenkai was a person, and Daxing City was designed and built by him with full authority.

"The prime minister has won the award!" Hearing Zou Yu call Yu Wenkai a master, the two brothers smiled happily and gave up their hands.

You must know that the craftsman has always been of a lower rank, even if it is Yu Wenkai, although he is reused, he is still not respected by others! What others respect more is his status as a military general. And can be called a master! It's not a monk from a temple! That's the highest compliment to an achievement! Further up there are saints!

Yuwen Rutong is white and fat, Yuwen Wen is tall and stocky, when he gave his hand, Zou Yu found that his palms were thick, and he looked more like a general! However, just the three words of Yu Wenkai will not make people doubt their brother's level.

"This is Li Chun, the young eunuch of the craftsman prison! A stone bridge more than 20 zhang long was once built! Yan Liben introduced to the last black, thin, gray-haired old man.

"Li Chun!" is another famous character through the ages, who may not know Fang Xuanling, but Li Chun, an ordinary name, is rarely known as soon as it is associated with the repair of bridges.

Zou Yu's eyes lit up, and he hurriedly pulled Li Chun and said enthusiastically: "Everyone, please take a seat!" ”

"You can come to Jinyang, I am very grateful! Regarding skilled craftsmen, a classification is about to be implemented, and please help refer to it! Inviting a few people to sit down, Zou Yu couldn't hide his happiness and said.
