Although the technical patent system hundreds of years later has various defects, it is generally good and does not prevent Ying Yi from learning from it.

He said: "The term is set to ten years. It will fail after ten years. During these ten years, if you use your formula to forge two thousand kilograms of fine iron, you will get one tael of silver. If it is twenty thousand kilograms, it is ten taels. Two hundred thousand kilograms are one hundred taels, and so on."

He said, many thoughts emerged: "If you develop a new technology during this period, you will decide according to the same rules."

As soon as these words were spoken, both Li Sansi and Pu Tiechhui opened their mouths in surprise.

"Sir, what you said is countable?"

Pu Tiehammer said anxiously.

Ying Yi nodded seriously: "Why don't you do it? Unless I, Ying Yi, die, I will do everything according to this rule."

He told Jiang Xi: "This matter is recorded separately, and the relevant technologies must be entered in detail. According to the importance of each technology, rewards and compensation at the corresponding level are called technical patents. As for whether the technology is important, why should it be located, and how many patents should it be, you will discuss with Pu Dajiang and the others and take out a charter as soon as possible to check out."

After saying that, he said to Pu Tiehui: "Every craftsman, as long as he has unique skills, will follow this rule. Of course, it is not mandatory, but will do it according to the principle of voluntary action."

"Thank you! Thank you!"

Many craftsmen around heard it and talked fiercely for a while. Li Sansi and Pu Tiechu were filled with tears and bowed endlessly.

"This is what you deserve." Ying Yi smiled and said, "No one paid attention to it before, so he didn't understand the importance of craftsmen, but for me, it's different. Craftsmen are very important, and craftsmen's skills are even more important. I just hope that everyone will study more useful new technologies in the future, and then they will be rich and powerful."

Leaving the Huozi Workshop and then going to the Jinzi Workshop, Pu Tiech was still immersed in joy and couldn't extricate himself.

When Ying Yi asked him, he was still stunned.

"Does there any craftsmen who make guns and cannons in the golden craftsman group?" Ying Yi asked him.

Pu Tiechhui was stunned and said, "Firemaking Equipment?"

Ying Yi nodded: "Firearms are powerful, both the court and the thief have firearms. If I don't have them, they will be easily restrained. The conditions are difficult now and I'm not waiting for it. Although I don't consider making firearms for the time being, it will be certain in the future."

Pu Tiehui grinned and said, "The adults are asking the right person. The little old man can make firearms. Three-eyed guns, nine-headed birds, and tiger squatting cannons. All the old man knows how to build them."

"oh?!"

Ying Yi was overjoyed and said, "Master Pu can make firearms?! OK, okay, I'm relieved now."

He thought about it: "After the order for this batch of 10,000 gun heads is completed, you will start making firearms for me." He paused again and said: "First, it is lightweight."

The late Ming Dynasty was an era when firearms were dominant. There were many types of firearms, and their power should not be underestimated. Without firearms, they would be inherently weak. Once they fought, they could imagine the situation when facing the enemy's firearm troops. At present, Ying Yi had no choice but to have nothing, so he could only equip the spear first. But it did not mean that Ying Yi did not pay attention to firearms. If he could not equip the equipment for the time being, he had to prepare to equip the firearms.

Ying Yi had experienced the power of the firearm. He was chasing a tiger at that time. That night, he was caught off guard and was drilled into his arm by a musket. Although it only broke the flesh and did not hurt the bones, it was because Ying Yi was strong. An ordinary person was basically disabled when he hit the arm.

Hao Yaoqi attacked Ye County, and Zheng Yunzhi also relied on five tiger squatting cannons, allowing Hao Yaoqi to attack and retreat several times.

"If you want to be light, the three-eyed gun is only a few kilograms, and the nine-headed bird is more than twenty kilograms, which is not heavy." Seeing that Ying Yi was so interested in firearms, Pu Tiechu hurriedly said: "The tiger-squat cannon is also the lightest cannon. But if it is said that it is powerful, the Fran machine cannon is stronger than the tiger-squat cannon, and the red-clothed cannon is more powerful. It can be shot farther. If it is a gun, the Lumi cannon is stronger than the three-eyed cannon. Unfortunately, the old man would not make these three."

Ying Yi was already satisfied and smiled and said, "There are similarities in the technology of firearms. Take your time first and study it while making it. Once the technology is released, I will also give you a patent."

Pu Tiechhui smiled and opened his mouth.

Then he explained the characteristics of firearms in this era in detail to Ying Yi, so that Ying Yi had a better understanding of firearms. The firearms in this era were relatively primitive, mostly front-mounted firearms and ignited with fuses. Once it encounters rainy days and heavy humidity weather, it will be difficult to use.

The difficulty in manufacturing a firearm is first of all, the manufacturing of the barrel and the barrel, which involves the issue of airtightness.

It takes a long time to drill holes in the middle with a whole solid iron rod, and several of them may not be able to be made in a month. The airtightness of the barrel is not guaranteed by wrapping the barrel with iron. In addition, it is the limitation of materials. The steel in this era may have reached the hardness, but its ductility or toughness is insufficient. It is used to build guns and cannons, and its service life is very short. The ductility of copper is better, but it is more expensive than iron.

Ying Yi listened and occasionally said, "That is to say, we must first solve the problem of the material, and then the problem of the barrel and barrel. I don't have any good suggestions on the material. I hope you will study it more and see if there are any formulas that can make the steel more resilient. As for the barrel..."

His heart kept moving, and he couldn't think of any good idea. Ying Yi didn't have much understanding of machinery and manufacturing.

"Learn more." He sighed: "Maybe we can use the power of water."

Pu Tiechhui said: "There is no suitable place for Bibo Valley. It is dry now, and the mountains and streams flow in shallow water. The old man knows how to get the water mill, but there is no place to get it."

"Water mill?" Ying Yiqi said: "What is a water mill?"

Although he had already guessed in his heart, he still couldn't help asking.

Pu Tiehui said: "Sir, you should have seen a water truck? You can use water mills in places where the water is stable and turbulent. The same principle is the same as the water truck, but there is only a slight difference..."

Then he talked about the principle of water mill, and Ying Yi couldn't help but be amazed after listening carefully.

It is probably a hydraulically driven gear transmission machine, which can not only be used to drill the barrel, but also forging and sawing.

According to Pu Tiehui, such technology is widely used in large workshops.

When Ying Yi heard this, he couldn't help but be amazed by people's wisdom.

The ancients did not have technology or wisdom. It was just that in the history of Zhuxia, technology was demonized and suppressed and not taken seriously.

He suddenly had a whim: "Can animal power be used instead of hydraulic power?"

He said, "It's like using a donkey to push the mill?"

Pu Tiechhui shook his head: "My lord's idea has been tried before. But animal power is not as stable as water power. There are times when animals can get rid of their kids."

Ying Yi was silent.
