"What?" Lao Cheng on the side was talking positively, and he didn't hear what Li Chengqian said for a while.

"I mean, the knife is made of Damascus steel." Li Chengqian rubbed the exquisite pattern on the short dagger in his hand, with a layer of misty light in his eyes: "This kind of sword made of steel is several times better than my Datang's hundred steel, and it is easy to sharpen iron like mud." ”

"What? Really? Although Lao Cheng had seen the appearance of the short dagger, he didn't dare to believe that this knife would sharpen iron like clay.

"Nature is true." Li Chengqian turned his head and glanced at Lao Cheng, suddenly raised his hand and poked it on the table.

With a 'bang', the blade of the knife went straight to the handle.

"Donkey day, this knife is really so sharp!" Lao Cheng looked at the short dagger standing on the table in surprise and muttered.

"I don't know?" Li Chengqian didn't expect Cheng Yanjin to not know that a sword made of Damascus steel could sharpen iron like clay, and he couldn't help but be a little surprised.

"I Lao Cheng saw that this knife was beautiful, and I planned to take it back to my granddaughter, I thought it was an ornament, but I didn't expect it to be a sharp weapon." Cheng Yanjin frowned and looked at Li Chengqian, and asked with some uncertainty: "Didn't you kid take a fancy to this knife and want to keep it for yourself, right?" ”

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

"Che, do you think the old man will believe it?" Cheng Biting Jin pouted and said.

"It doesn't matter, I just want to inform them now, and try to get back as many craftsmen as possible from Tianzhu, Dashi, and Persia, these guys have a lot of good things in their hands, and it will definitely not work if they don't take them out."

"Then you do it slowly, the old man will go back!" Cheng Yanjin was most bored with government affairs, and when he heard Li Chengqian talk about it, his head immediately became big, and he got up to say goodbye.

And what about Li Chengqian? Comrade Xiao Li is naturally indispensable, anyway, this old man still has a pass to pass after he goes back, let's go, leave early to pass the test early.

……

Lao Cheng left, and Li Chengqian became idle again, but compared to the drowsiness just now, he had to figure out how to transfer some craftsmen from the Western Regions.

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

It's a pity that now Li Chengqian is grounded, and he can't leave the Qin Palace, and all his rights have been taken back by the old man, otherwise...... Well, there's actually nothing else.

If you want to make a great leap forward, it will be impossible to achieve it without a certain accumulation.

The reason why Datang made a leap in all walks of life some time ago was also because there were a lot of technical reserves in the people, but the previous court did not pay attention to it, so it was left until he Li Chengqian carried it forward.

Nowadays, the power of those private reserves has basically been exhausted, and if you want to improve Datang's production technology, you must rely on external forces.

……

After biting the pen for a day, Li Chengqian finally wrote an excerpt that needed to mobilize craftsmen from the Western Regions and Tianzhu, and after using the seal on it, he re-examined it, and finally said to Yang Yuxin behind him: "Look, your Royal Highness's calligraphy has made some progress, right?" ”

"Yes, yes!" Yang Yuxin hesitated for a moment, but finally nodded firmly, but what she thought in her heart is unknown.

"Hypocrisy!" How could Li Chengqian not know what Yang Yuxin's thoughts were, he glanced at her helplessly and said indifferently.

"It's not Your Highness, you, you write this word, the anti-counterfeiting effect is indeed better!" Yang Yuxin explained very seriously.

"Poof......" Xiaobai couldn't hold back for a while, and laughed out loud.

This is so embarrassing, Li Chengqian stared at the fold in his hand, rolled his eyes, and thought of the scene where the old man tore off the fold because he couldn't understand it after only reading two lines, and finally reluctantly compromised, turned back to Yang Yuxin and said, "Then you can come, copy it according to this!" ”

"Yes!" Yang Yuxin forced a smile and leaned over to Li Chengqian's side, picked up the pen and .......

……

Li Chengqian's small request is naturally indispensable for the old man, after the feast, the old man drank a little high, and after reading the excerpt that was urgently delivered, he approved a big reading, and then let people send it to Zhongshu Province, so that Old Man Du and others could look at it.

Chang'an City has also begun to become a little different because of the return of this group of old guys, there is always such an inexplicable tense atmosphere, and there seems to be a smell of gunpowder in the air.

And the major families have become much more honest almost overnight, and even the gentlemen who drink flower wine are much less than usual, as if there is some tacit understanding between these families and the nobles.

……

In the Ying Guo 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 places in the hall, there were half-grown old men with serious faces, as if they were waiting for the leader to speak.

With a "snap", Xiao Wu, who was sitting on the main seat, raised his hand and snapped his fingers, attracting the attention of a group of half-grown old men, and at the same time, several domestic servants also came in outside the living room, each holding a plate in his hand.

"This? What is it? Looking at the handfuls of pure white substance on the plate, a group of half-grown old men asked in confusion.

"Sea salt!" Two simple words came out of Xiao Wu's mouth.

"What? Sea salt? This, is it salt? ”

"yes, how can this be salt? Isn't the salt of the sea bitter? ”

"yes, yes!"

A group of half-grown old men didn't believe it very much, and some curious ones dipped some of them in their hands and put them in their mouths to try it, but their faces changed instantly, and they snorted with a face: "It's indeed salt!" ”

"Sea salt is produced in Dengzhou, we can send it to you at the previous price of seventy, I wonder if you are interested?" Xiao Wu said with a smile after everyone confirmed the authenticity of those salts.

"What? Seventy percent of the previous ones? A group of half-grown old men showed expressions that were even more shocked than when they heard Haiyan just now, and they couldn't digest the news revealed by Xiao Wu for a while.

"Yes, seventy percent!" Xiao Wu nodded.

"Martial girl, can you ask how this sea salt is made?" The old men, who weren't sure about the truth of the matter, decided to find some other questions to deal with first.

After all, this is not a small amount of less than the previous salt price, which can affect almost a lot of things for them, so they have to think about it.

Xiao Wu was a little amused by the idea of these half-grown old men delaying time, but he didn't say anything, and explained indifferently: "As far as I know, this salt is sunburned, and as for the specifics, I'm afraid you will only know when you go to Dengzhou to have a new look." ”
