For the task of Li Tianyang to force the R&D Institute, Yang Zhi and Chengcai had a hard time during this time, and it has become the norm for more than a dozen core members of the R&D Institute not to return to the dormitory or take a bath for a few days.

In the end, within the limited time given by Li Tianyang, Yang Zhi and their research made a breakthrough. In fact, Yang Zhi and Chengcai found several ways to refine gold from ancient books, and each of them refined gold under their research.

"First of all, we have to grind the gold ore into powder through the method of alternating hot and cold, which is the most time-consuming and energy-consuming thing." When this final process was finalized, Yang Zhi and the others invited Li Tianyang to observe this gold refining process. No, Yang Zhi is operating on the spot and verifying the "lead mixing and soot blowing method" for Li Tianyang on the spot.

"But we also have other ideas, to see if we can use the combination of hydraulic power and bearings to develop a set of automatic ore grinding machines!" On the side, Chengcai also interjected, and also said a project that only had a proposal in their R&D institute, and the implication was naturally that Li Tianyang wanted to allocate more resources for their research.

"The idea is good, if there is anything you need to report, I hope to give a practical result as soon as possible." Li Tianyang can also see that grinding the ore into powder is probably the most difficult step in this process.

It's normal to think about it, ancient tools are already very scarce, like grinding mineral powder, most of them can only rely on the principle of thermal expansion and cold contraction, so the resources consumed are naturally not small. Therefore, when Cheng Cai saw the needle and said their idea that they had not yet made the trip, he naturally obtained Li Tianyang's approval.

"Next, it is to separate the gold-containing mineral powder from ordinary stone powder by washing it with water, like this!" With Li Tianyang's support, Yang Zhi also had a little more strength to speak at this time, and the smile on his face was even stronger.

There is too much research work in the R&D Institute, and more than a dozen R&D cores, as well as their respective R&D teams, each has its own project, and the resources and materials spent are like running water, and it also takes up the help of most of the craftsmen and masters in the craftsman's workshop, but in the end, many R&D results have ended in failure.

There have been many such things, and Yumo, who is the mayor and chief financial officer of Bengang, naturally has opinions on this R&D institute, which makes Chengcai and Yang Zhi's life not so easy!

Therefore, when Li Tianyang threw the task to their Bengang R&D Institute this time, Chengcai and Yang Zhi wanted to perform in front of Li Tianyang this time, and the intention behind them was naturally to hope that Li Tianyang could open the back door to their R&D Institute and give them more resources.

Now that they have the support of Li Tianyang, after they go back this time, they can also use chicken feathers as arrows and ask Yumo, the chief manager, for more materials and resources to come back for their research.

“………”

"Finally, we mix these lead balls wrapped in gold with plant ash and smelt them, and at the same time blow a large amount of air into them through the bellows, and then we can smelt the gold out." As he spoke, Yang Zhi, who was actually operating, guided a drop of golden liquid the size of a pea out of the melting channel next to the furnace as if by magic, and after it fell into the basin of water to cool down for a while, Yang Zhi fished it out of the water and handed it over to Li Tianyang: "This method is determined after we have experimented with several ancient refining processes, which is relatively simpler and does not require too many other raw materials. Moreover, by comparing the fineness and condition of the gold refined at the end, the gold produced by this method, even if it is refined in batches, can finally ensure that the gold content is more than ninety, while other methods are only about eighty percent at most! ”

Li Tianyang's eyes were obsessed, staring at this little golden product, and at the same time, thinking about the process of Yang Zhi's demonstration in this more than an hour, his whole mind couldn't help but start to drift.

Although it has not yet been produced on a large scale, I saw with my own eyes that the ore brought back from the Jilongshan mine turned into yellow and clear precious gold in front of my eyes. Thinking about the immeasurable huge veins in the Jilong Mountain Mine, Li Tianyang finally believed in his heart at this time that this time their team was really going to make a fortune!

"Can you give an approximate figure of how much gold our veins can produce in a day based on a thousand strong laborers?" Li Tianyang's heart was so excited that even the corners of his eyes were smiling like crescents at this time.

"The quality of this vein is good, and the gold content is quite large, and if it is calculated by a thousand people, it should be able to mine and refine about 5-6 taels of gold in a day." Yang Zhi and Chengcai carefully calculated, and then gave a rough answer: "Mainly in the two processes of mining ore and grinding ore powder, too much manpower is needed, but the next few steps do not require too many manpower, just the few masters with pig iron refining experience who are dispatched are enough to catch up with a few guys!" ”

"Is it only five or six taels?" Li Tianyang was disappointed, he didn't expect that they had Baoshan in their hands, but they couldn't immediately convert it into real money, and the excitement in his heart brought by the windfall was suddenly replaced by a strong disappointment, and the huge contrast between the two emotions made Li Tianyang's face look very ugly: "Then can you think of a way to improve these two processes?" For example, when mining, can you use gunpowder and abandon the method of burning? ”

"This method is completely feasible, in fact, the principle is the same as the blasting of artillery, that is, the only difficulty is how to make a pit in the hard ore to hold gunpowder, so as to achieve the purpose of blasting!" Chengcai very much agreed with Li Tianyang's idea, thinking that he had also studied it, maybe the method was not mature, and the key points had not yet been broken through, so he didn't tell Li Tianyang.

"Oh, by the way, you look at my memory, just now you also said that you used the combination of hydraulic power and bearings to build a machine for grinding mineral powder. How, do you have any design inspiration? Li Tianyang patted his head at the same time, self-deprecatingly cleaned up his frustration, and asked with interest about the grinding machine concept that Chengcai just said.

"We have completed the general idea, now we need to step by step to transform the idea into reality, and gradually improve the flaws, if there is no shortage of resources, materials, research and development is smooth, we can come up with a mature plan within about half a year." Chengcai said confidently.

"Good!" What Li Tianyang wants is the momentum of becoming a talent, so he looked at him with a lot of expectation and satisfaction: "In this project, I will open the channel for you, and I will fully meet your needs!" ”

At this time, Li Tianyang spoke again, no longer perfunctory to Chengcai just now. Seeing this, Chengcai and other R&D personnel couldn't help but be satisfied with their faces, and they all smiled and assured Li Tianyang.
