A few months later, when gunpowder was used on a large scale in the mines, the dull sound of explosives mixed with the artillery training of the soldiers at the Jilongshan garrison paid no attention to the slight difference in the sound.

Wan Liang and the others once again quietly came to the camp of the Jilong Mountain mine, and this time, they were accompanied by a team of members of the R&D Institute headed by Chengcai.

The large-scale apparatus for grinding mineral powder that had been promised to Li Tianyang had been completed, and they had also made a relatively small model in Bengang. When they reported the matter to Li Tianyang and reported the relevant data of the mold, Li Tianyang, who got the data and illustrations, was extremely surprised by the achievements of the R&D Institute today, and at the same time, he also had great confidence in their R&D.

In fact, the ore grinding equipment researched by the R&D institute is not complicated, but the most eye-catching part of the whole instrument is its power system. Chengcai abandoned the scheme of using manpower as the power to provide the equipment, because in the whole set of equipment, there is a component of a large hammer weighing more than 300 catties, which is specially used to smash the ore and facilitate the subsequent grinding.

If it is artificial, the hammer of more than 300 catties will work day and night, and I am afraid that no matter how many people are arranged in it, it will not last long!

They are talented, but they skillfully combine the circulating power of the waterwheel, and combine the waterwheel with the hammer using gears. When the lever connected by the hammer is raised step by step by the gear of the waterwheel, it will naturally detach from the gear after reaching a certain height, and the potential energy contained in the hammer will be converted into powerful kinetic energy, and then work in the ore in the groove at the bottom to achieve the purpose of decomposing the ore.

In the eyes of later generations, this research program can only be said to be a slightly crude tool, but at that time, it was a major progress, because this system brought a new system that abandoned human power as a source of power, and it can be said to be an epoch-making system.

Of course, the knowledge of physics such as potential energy, kinetic energy, and work is not at all in the minds of the R&D personnel who have become talents.

However, if you want the river to be able to rotate and match the waterwheel with the entire power system, the turbulence requirements for the water flow are naturally higher. There is a small stream two or three miles on the edge of the Jilongshan mine, but the flow of this stream is a bit stretched to irrigate hundreds of dumps of land, and it is difficult to drive a waterwheel that requires strong kinetic energy.

However, they have long thought of a solution, that is, to use cement as a construction weapon, choose a geographically excellent location around the creek, cut off the creek, and artificially build a water storage dam.

At the same time, at the bottom of the dam, an outlet is built to connect the waterwheel system to the outlet, and the strong pressure of the raised stream water is used to artificially turn the originally gentle flow into a rapid, dynamic and capable of driving the waterwheel system to rotate.

Even, in order to strengthen the transmission effect and enhance the efficiency, they have put a lot of effort into every small component, and I am afraid that the first bearing of this era has been placed in this system.

The bearing on the schematic diagram is not the kind of precision bearing that Li Tianyang used to make wooden cars when he was a child, but the precision steel ball is replaced by a section of iron cylinder. Due to the backwardness of the standard technology, even if it is this kind of simple bearing, it will take a lot of effort to be qualified to manufacture one, and there are countless wasted materials.

When Li Tianyang got this whimsical research and development results in the eyes of outsiders, the shock in his heart was speechless. The results of their research and development were completely done by their entire R&D institute, and Li Tianyang did not participate in it from beginning to end. But it is precisely because of the lack of Li Tianyang's participation and the guidance given to them by future generations that they have been able to study such a miraculous grinding system, and anyone will be shocked.

When he got this report with detailed data and illustrations, Li Tianyang just glanced at it, and immediately made a decision, asking Chengcai and them to go all out to turn this report into reality. Even in order to give them the greatest support, Li Tianyang recruited the top craftsmen and masters of the craftsman's workshop to Jilonggang together, as their reserve force, ready to help them overcome all kinds of difficulties.

In this way, they naturally have more confidence, and immediately pulled half of the core members of the R&D Institute to the Jilongshan Mine to inspect the site of the dam and the site of all supporting facilities.

Half a month or so passed, and when Li Tianyang received the news of the rebellion of Yong'an Tusi in the Ming Dynasty, Chengcai and the others also brought information that their dam was about to start.

The specific reason for the Yong'an rebellion, even with the Guiyang Tusi who was very close to Guangxi, was due to the official report obtained by Cao Yongyi, because after the defeat of Shenyang in March, the Liaodong defenders who had lost their troops were in urgent need of replenishment, so they transferred ethnic minorities from Yong'an and Guiyang to garrison, causing dissatisfaction among the local Tusi and tribes, so there was a rebellion involving the two places.

The reason why Li Tianyang paid attention to this chaos was because the Liangguang area was adjacent to Guizhou, so at the beginning of the war, many people fled to the coastal areas of Guangxi. This also gave Li Tianyang an opportunity for them to recruit people on a large scale.

A long time ago, the number of people that could be recruited in Zhangquan was almost recruited by Qi San's team. To this day, Qi San and the others want to recruit people, and they have to go to more distant Jiangsu, Zhejiang, and even Anhui, Shandong and other places to recruit, and then use the big ship of Qixintang to transport them back to Dayuan Island.

Finally, now that there is an opportunity to recruit a large number of people at the doorstep, how could Li Tianyang not pay attention to the movements!

Therefore, when he learned the news, he passed the news to Qi San and them, asking them to step up their efforts to send people to Guangxi, and even go deep into the interior to recruit the displaced villagers.

After receiving Li Tianyang's letter, Qi San and his gang also hurriedly took action, and now although Qi San is still independent from Li Tianyang's team, in fact, his gang, whether in the eyes of outsiders or in essence, is already a peripheral organization of Li Tianyang and their Qixin Hall.

Basically, all the economic resources of the Qisan gang are dependent on Li Tianyang's team, and by recruiting people for Li Tianyang's errands, and carrying goods for Qixintang and several businesses that Qixintang is familiar with, the Qisan gang now has nearly 1,000 good hands up and down, all of whom rely on Li Tianyang to feed them.
