Li You has the world's top weapon-making technology, such as the production of Japanese swords. But he can't operate it, which requires the long-term practical experience of craftsmen.

He planned to impart these techniques to these craftsmen, so he asked Li Laogan to summon the craftsmen to explain to them.

Suddenly, he remembered something, so he let the craftsmen disband, leaving only Li Laogan behind.

He asked, "Li Laogan, how many helpers do you need to build a horizontal knife?"

Li Laogan said: "Just have me and my two sons."

Li You said: "Okay, just keep your son. I will only teach you this knife forging technique."

Li Laogan said, "Thank you, the prince, thank you, the prince." However, he didn't believe it in his heart, thinking that the prince wanted to draw the secret of the knife-forging technique from him. He thought, "I have to be careful of him, and I won't say a word I shouldn't say."

Li You said: "You are using the 100-steel making technology handed down from the Han Dynasty..." He explained in detail the 100-steel making technology and the method of making composite tools. Not only was it the same as Li Laogan mastered, but it also improved on his basis.

Li Laogan broke out in a cold sweat, and he thought to himself: "When my son and I were fighting swords, we were very careful to prevent others from seeing them. Unexpectedly, we were peeked at by others and told the prince. What should we do? I'm sorry for my ancestors."

Li You began to explain the modern production craftsmanship of Japanese swords to Li Laogan, and he was so excited. Only then did he realize that the prince in front of him was a real master.

Li Laogan was excited and forgot his identity and said, "Prince, please accept a villain as his disciple."

Li You was not unhappy with such unreasonable actions, and Bai Hu and others around him were not angry either, because they knew that the prince would not care about these things.

Li You smiled and said, "I will teach you these techniques, so there is no need to become a disciple."

Li Laogan suddenly realized that he was a little unlucky. He hurriedly said, "Prince, I don't know how to speak. I deserve to die. Please punish me." Seeing his father like this, his two sons hurriedly knelt aside, and didn't dare to show off."

Li You smiled and said, "It's okay, get up. I don't accept you as my disciples. It's not that I look down on you, but I just know the method of forging swords, but I don't know how to create them myself. I have to learn from you. Therefore, we are learning from each other and learning from each other, and there is no such thing as a master and apprentice."

Li Laogan had long heard that this prince is approachable, but now he sees this, and he can't feel at ease.

Next, Li You began to guide them to forge according to the modern Japanese knife production technology.

For 10 days, Li You spent his time in the blacksmith shop, guiding Li Laogan and his son, and finally created the Japanese samurai sword. Given that the Japanese samurai sword was originally improved on the basis of the horizontal sword, its ancestor was the Tang sword. Therefore, Li You named it Tang sword.

On this day, Li Laogan took a forged Tang sword and handed it to Baihu for testing. After testing, the performance of this knife exceeded that of the horizontal sword. Only the horizontal sword in the Tang army's existing weapons can compete with this samurai sword, and the weapons they are all at a disadvantage.

As for the miscellaneous weapons produced by the grassland people, Tubo people, Western Regions and other countries, many of them were cut into pieces under the blow of the Tang sword.

These days, Li You and Li Laogan and his son have become very familiar with each other. He usually wears uniform work clothes in the mine.

On that day, he sat on a bench in the blacksmith shop and said to Li Laogan: "The Tang army needs a large number of weapons. It will take several days for you father and son to build a Tang sword. This is too inefficient.

The technique of forging knives is yours. I don’t ask you to pass it on to others, but the Tang army needs weapons, so it’s not possible to rely solely on you father and son.

I have an idea to discuss with you, and see if this can be done. You divide the technology of breaking the knife into eight processes, and each process teaches a group of people. These people are only responsible for this process, and their technology will be very refined, but they do not master all your technology. Your technology will not be lost, and it can exert its efficiency."

Then, Li You explained to him the method of assembly line operation.

Seeing that the prince was so considerate of him, Li Laogan thought this was a good idea, so he said, "Prince, the villain is willing."

Li You said: "Okay, I'm going to build a weapon workshop for the Ministry of War here, and you will be the supervisor. For the time being, I'll be positioned as the eighth-rank."

Li Laogan didn't expect that he could become an official, so he hurriedly saluted and expressed his gratitude.

There is another reason why Li You did this. He proposed to establish patent technology protection and improve the status of inventions and creations.

In the Tang Dynasty, inventions and creations were regarded as strange winning techniques. The Ministry of Works stipulated that after an invention was adopted by the court, the maximum reward was 5 guan!

...

"Pulingling." In the guest house of Xigou Iron Mine, a gray carrier pigeon rose into the sky and soon disappeared into the sky.

The carrier pigeons trained by magpies can now assume the role of communication. They have started to be used in departments controlled by Li You, such as Qiwang Mansion, Research Institute, Industrial City, Mining School and Xigou Iron Mine.

After Wu Qi watched the carrier pigeon disappear, he returned to the house and said, "Prince, I've sent it out."

Li You said: "Yu'er, inform Baihu and set off today to return to Chang'an."

Not long ago, he received a letter from Yin Guanghao, saying that Li Tai would offer a gift to Empress Changsun’s birthday next year, and would spend 100,000 yuan to build a Buddhist silhouette in Binyang Cave, Longmen Mountain, and to pardon the world. Li You was too lazy to do such flattery and too lazy to care about this kind of flattery.

But, Li Tai, you say that he does nothing and is useless to do things that cost the people and cause money, he will also harm others - he suggested that the institute pay him money, and Li Shimin actually agreed!

Wei Zheng felt that this matter was inappropriate, but the reasons for opposition were not sufficient. Changsun Wuji was inconvenient to speak, and Xiao Qian had already received Li You's advice and only asked him to take charge of the affairs of the Ministry of Education.

Li Chengqian is still like that, and he can't deal with such a difficult problem. He is a filial son himself, so he cannot object to such a thing. The problem is that this matter is too cowardly.

In fact, this is a carefully planned situation by Li Tai. It seems simple, but it is difficult to crack. This incident not only hit Li Chengqian and Li You, but also ended up with the reputation of filial piety, and it also easily won the favor of Li Shimin and Empress Changsun.

This is obviously bullying people, but under the banner of high-sounding sound, he is tying up the tiger's skin as a banner. However, Li Shimin favors Li Tai and is very happy that he can fulfill his filial piety to Empress Changsun.

Li Chengqian, Yin Hongzhi, Wei Zheng and others all sent people to the Qi Palace to ask them to notify Li You.
