However, no matter what, it can be used and machined. In the Tang Dynasty, it is definitely a great invention and a stunning masterpiece!

Kou Yibing kept shook his head and felt regretful: "We also want to make another one, but we can't make this thing. It's a pity, it's a pity!"

Li Yuanba was still excited and patted Kou Yibing on the shoulder and said, "Don't worry, let's build knives first, and then build one that is more advanced and more useful than this."

"Really?" Liu Wenjing and the other two asked in unison.

Li Yuanba is now in a high spirit and patted his chest and said, "Absolutely no problem!"

"That's great!" Ye Wanqing's crutch kept placing on the ground and said with a smile. Kou Yibing clenched his fist with his right hand and burst into laughter. Liu Wenjing couldn't help but slamming his high fives: "If we really want to do it, we can make other things. We have thought about a lot of things, but the knife is limited and we dare not do it."

It can be said that this is the prototype of a machine tool. It is not impossible to make a machine tool if it only needs to be changed. As for this power system, there is no electricity or steam engine, it is better to drive a donkey? If it is not easy to drive a donkey, it can also be completed with hydraulic power.

Li Yuanba has used the machine tool and is very familiar with it. Although he has never made it. However, our ancestors could build the most primitive lathes, and they could not make it if they were able to work together with the power of the generals and military weapons. They didn't believe that they could not make it. As for modern lathes, Li Yuanba dared not think about it. At least it was better than the one in front of him. Li Yuanba was still full of confidence.

"Have you ever checked, which ancestor did this?" Li Yuanba thought too much about knowing the name of this ancestor.

Liu Wenjing shook her head and said, "The prince wants to know the name of this outstanding ancestor, but we don't want to find out. In order to find out the name of this ancestor, we asked the doctors of the Imperial College to search for books from the previous dynasty in depth. After decades of hard work, the doctors of the Imperial College were also useless."

Imperial College was the highest institution of learning in the Tang Dynasty. Even these doctoral students who were dedicated to studying were unable to do anything. Who could do anything? Chen Shirong sighed lightly, and another ancestor who should have been remembered for generations could only be called "Anonymous".

We often say that ancient China's science and technology were ahead of the world, but in fact, the leading level shocked us. It is not just the "four major inventions" we like to talk about, but also in terms of machining, China is no worse than Western countries.

The Qin Dynasty copper arrow cluster unearthed from the Terracotta Warriors is three-sided conical, not to mention aerodynamics. The processing accuracy is even more shocking. When tested with modern instruments, the error is zero.02 mm. Such accuracy is naturally nothing in our modern society, because we have machine tools, computers, vernier calipers, and spiral micrometers. However, this happened in the Qin Dynasty two thousand years ago, which is really shocking.

The clear threads appeared on the golden instruments of the Tang Dynasty, but how the Tang people did it. We have not been able to solve this mystery yet. There must be some kind of processing tool, and only this tool has been buried in the dust of history, which is a pity!

After sighing for a while, Li Yuanba rolled up his sleeves and said, "Come on, I'll tell you about making knives." Until now, Li Yuanba's mood has not calmed down, and his voice is a little louder when he says this.

Liu Wenjing and the other two hurriedly surrounded him. Li Yuanba explained how to carburize and quench according to his memory. In fact, they had already studied it. Listening to Li Yuanba's words was like lifting the clouds and seeing the blue sky, and he was fascinated by listening to it. By the time Li Yuanba finished speaking, they had almost understood and had more confidence. Kou Yibing seemed to be thirty years younger, and kept patting Li Yuanba's shoulder: "Crown Prince, you are so cute! We don't understand anything, you will know anything, wonderful!"

"This is the most important thing!" Ye Wanqing agreed with the high-five.

Liu Wenjing's face was shining: "I tell you that we have to have a good drink tonight. Call all the masters, and we discussed while drinking, and figured out some unknown things."

"Yes!" Li Yuanba was extremely interested and was the first to agree.

The four of them were very happy, and they left the house and locked the door. When they saw the sky was getting late, Kou Yibing smiled and said, "Today, we won't do anything, let's discuss it first."

No one will object to this proposal.

The next day, Li Yuanba rushed to the military weapon supervisor if he had something to do.

Seeing Ye Wanqing and the others standing at the door from afar, looking around, as if waiting for someone, a little anxious. Seeing Li Yuanba coming, Ye Wanqing and the others came up to us, Ye Wanqing complained: "Crown Prince, you are here just now, so there is no hurry."

Li Yuanba smiled and said, "Master Ye, it's not that I'm not in a hurry. I had something to do last night. I slept late and got up late. Please forgive me."

"It's good if you come, it's good if you come!" Kou Yibing looked like a good old man.

Li Yuanba asked, "What's the matter with you waiting for me?"

Ye Wanqing and Li Yuanba had an extraordinary relationship and smiled and said, "Crown Prince, of course, Master Sun and his friends went to Mianzhou. They are ready, just wait for you to come and explain, and you can go on the road."

As the "project leader", Sun Nanhu and his friends went to Mianzhou to deal with the saltpeter matter. They naturally had to meet Li Yuanba before their trip to find out if Li Yuanba had any other instructions.

Li Yuanba asked while following Ye Wanqing and the others in, "Master Ye, how are you doing there?"

Ye Wanqing had not answered yet, and Kou Yibing took over the conversation: "Crown Prince, don't worry, Brother Ye is still worried about doing things? No problem, the progress is good."

Liu Wenjing continued: "Not only is Master Ye's place good, but we discussed the knife all night last night, and we also had some clues and it is very likely to make it."

Between artillery and knives, Li Yuanba valued tools more. Once the machining tools were released, they would start the machining era, which had a very far-reaching impact. Li Yuanba was very excited when he heard this: "Oh, really? Have you started doing it?"

Ye Wanqing patted Li Yuanba’s shoulder: “Prince, I didn’t tell you that we have tried many methods of this knife before, but none of them succeeded. Yesterday you said that we gathered the masters and discussed while drinking. The duckbill with a chicken’s mouth really came up with a set of methods. Is there a 100% chance of success or 80%.”

"This knife has bothered us for so many years, and finally we have a look of surprise. Everyone is happy and finally blushed. However, we have not started to make this knife. To make this knife, we must first make some tools, and then we will make them." Kou Yibing was very excited: "It's here."

Li Yuanba and the others arrived at the door, and a group of people came out of the room, all of whom were military weapon supervisors and masters of the Jiangjiang Mansion, Sun Nanhu, Ouyang Fu and Li Xiaoyi.

After a brief greeting, Li Yuanba apologized: "I'm late, let everyone wait for a long time, I'll apologize here."
