"What?" Old Cheng was talking, but he didn't hear clearly what Li Chengqian was talking about for a while.

"I mean the material of this knife is Damascus steel." Li Chengqian rubbed the exquisite patterns on the short dagger in his hand, with a hazy light in his eyes: "The sword made of this steel is several times better than the Baijian Steel of my Tang Dynasty. It is no problem to cut iron like mud."

"What? Really fake?" Although Lao Cheng had seen the dagger, he couldn't believe that this knife would cut iron like mud.

"Of course it's true." Li Chengqian turned his head and glanced at Lao Cheng, suddenly raised his hand and poked hard on the table.

With a "bang", the blade body disappeared to the handle.

"Ah, this knife is so sharp!" Old Cheng murmured at the short dagger standing on the table in surprise.

"My father-in-law doesn't know?" Li Chengqian didn't expect that Cheng Yaojin wouldn't know that the sword made of Damascus steel could cut iron like mud. He couldn't help but be surprised.

"I, old Cheng, just saw that the knife is beautiful and planned to take it back for my granddaughter. I thought it was a decoration, but I didn't expect it to be a sharp weapon." Cheng Yaojin frowned and looked at Li Chengqian, asking uncertainly: "Didn't you like this knife? You want to keep it yourself?"

Li Chengqian shrugged: "There is no need for this, this knife is too short and has no practical significance."

"Tsk, do you think I will believe it?" Cheng Yaojin said with a lip silence.

"It doesn't matter. Now I just want to inform the Office and the others to get back more craftsmen from India, Dashi and Persia as much as possible. These guys have a lot of good things in their hands, and it is absolutely impossible not to take them out."

"Then do it slowly, I'm back!" Cheng Yaojin was most bored with government affairs. When he heard Li Chengqian say it, he immediately looked like a big fight and stood up to say goodbye.

And what about Li Chengqian? Comrade Li is naturally irrelevant. Anyway, the old man has another level to pass after he goes back. Just leave. It’s just right to pass the level early.

...

Old Cheng left, and Li Chengqian became idle again, but compared to the drowsy feeling just now, he had to think about how to transfer some craftsmen from the Western Regions.

The development of the Tang Dynasty has entered a bottleneck at this time, and it is very necessary to stimulate a foreign monk.

Unfortunately, Li Chengqian is now in a custody and cannot leave the Qin Palace at all. Moreover, all his rights have been taken back by the old man, otherwise... well, there is actually nothing else.

Technology is something that has, there is nothing, there is nothing. If you want to make a great leap forward, it will not be possible to achieve without a certain accumulation.

The reason why the Tang Dynasty made a leap in all walks of life some time ago was that it had a lot of technical reserves among the people, but the courts in the past did not pay attention to it, so it was left to him, Li Chengqian, to carry forward it.

Nowadays, the power of the private reserves has basically been consumed. If you want to improve the production technology of the Tang Dynasty, you must rely on external forces.

...

After biting the pen for a day, Li Chengqian finally wrote a memorial that needed to be mobilized by craftsmen from the Western Regions and Tianzhu. After using the seal on it, he reexamined it. Finally, he said to Yang Yuxin behind him: "Look, your highness's calligraphy has improved a little, right?"

"Yes, yes!" Yang Yuxin hesitated for a moment, but finally nodded firmly, but she didn't know what she was thinking.

"Hyit!" How could Li Chengqian not know what Yang Yuxin was thinking, and he glanced at her helplessly and said calmly.

"It's not your Highness, you, the anti-counterfeiting effect is indeed better!" Yang Yuxin explained seriously.

"Puchi..." Xiaobai couldn't help but burst into laughter.

This is so embarrassing. Li Chengqian stared at the note in his hand and rolled his eyes. Thinking of the scene where the old man tore off the note because he couldn't understand it, he finally compromised helplessly and turned around and said to Yang Yuxin: "Then come on, copy it according to this!"

"Yes!" Yang Yuxin held back her laughter and leaned against Li Chengqian, picked up the pen...

...

Li Chengqian's small request was naturally irresistible for the old man. After the banquet for the ministers, the old man drank a little high. After reading the memorandum of handing over, he approved a big reading letter, and then sent it to the Secretariat of the Secretariat, and asked Old Man Du and others to take care of it.

Chang'an City began to become a little different because of the return of these old guys. There was always an inexplicable tension, and the air seemed to be filled with a smell of gunpowder.

The major families became much more honest almost overnight, and even the playboys who drank flower wine were much less than usual. It seemed that there was a tacit understanding between these families and nobles.

...

In the Duke of Yingguo Mansion, Xiao Wu sat on the main seat of the hall, and Li Chengqian's sister-in-law Lin Doudou stood beside him.

In other locations in the hall, all the old men were seen, with serious expressions, as if they were waiting for the leader to speak.

With a "bang", Xiao Wu, who was sitting in the main seat, raised his hand and snapped his fingers. While attracting the attention of a group of half-big old men, several servants also came into the living room, each holding a plate in his hand.

"This? What is this?" Looking at the small handful of pure white substances on the plate, a group of half-big old men asked in wonder.

The simple words "Sea Salt!" were spoken from Xiao Wu.

"What? Sea salt? Is this salt?"

"Yes, how could this be salt? Isn't the salt in the sea bitter?"

"Yeah yeah!"

A group of half-big old men didn't believe it very much. Some curious people dipped some in their hands and put them in their mouths and tried it. As a result, they changed their faces instantly, and they twitched their faces and vomited: "It's true that salt is true!"

"Sea salt is produced in Dengzhou. We can send it to you at a price of 70% in the past. I wonder if you are interested?" Xiao Wu said with a smile after everyone confirmed the authenticity of the salt.

"What? 70% of the past?" A group of half-big old men showed a more shocked expression than when they heard Hai Yan just now. They could not digest the news revealed by Xiao Wu for a moment.

"Yes, 70%!" Xiao Wu nodded.

"Miss Wu, can I ask how this sea salt is made?" The old men who were not sure of the authenticity of the matter decided to find other questions first and make a quick break.

After all, the purchase price is 30% lower than the previous salt price, which is not a small amount. This can almost affect many things for them and must be considered carefully.

Xiao Wu was a little funny about these half-grown old men's idea of ​​delaying time, but he didn't say much and explained calmly: "As far as I know, the salt is sunburned. As for the specificity, I'm afraid you will know it if you want to go to Dengzhou to take a look."
