Turning their eyes back to Chang'an, Cheng Yanjin and the other three followed Dugu Yufeng to Li Chengqian's 'Lanruo Temple', and saw Li Chengqian painting, and there were a lot of scribbled papers next to the table. Eighty-one? Middle? Text ≥≠≤.≥8≤1=Z=

Several people looked at Li Chengqian's 'paintings' quietly, and after a while, Cheng Yanjin asked, "Boy, what are you painting?" It's uglier than a chicken plan. ”

Li Chengqian looked up at everyone, nodded to Qin Qiong to show his surprise, and then pointed to the picture he had drawn with the brush in his hand and said, "This is called a hydraulic stamping machine, a very useful machine. ”

"Hydraulic stamping? That's it? Cheng Yanjin also pointed to the pattern drawn by Li Chengqian.

I saw the picture...... Horizontal is not flat, vertical is not straight, there are countless hook circles, if Li Chengqian does not say that this is a drawing, anyone will be regarded as a naughty boy graffiti.

Li Chengqian's face was slightly embarrassed, and he said forcefully: "This is a schematic diagram, do you understand the schematic diagram?" It means maybe, probably, almost, maybe. Oops, anyway, Lao Liu can understand. ”

Liu Min wanted to say that he couldn't understand it, but under Li Chengqian's forced gaze, he could only nod his head and admit that he could understand it.

"What the hell is this for?" Qin Qiong knew that Li Chengqian never did useless work, as long as it was something he took out, it would definitely be of great use.

This can be proved by a series of ordnance that has significantly increased its power after modification, such as pulley bows, pulley bed crossbows, and steel pulley crossbows.

"Uncle Qin, please see, a big wheel here is the cylinder car we are using now, which drives the axle in the middle to rotate under the impetus of water. And then through the gears here...... And then there's the ratchet here...... Finally, you can mention a 50,000-pound iron ingot here," Li Chengqian put the 'schematic diagram' right, pointed at it with his hand, and briefly introduced the working principle of the Datang version of the hydro turbine.

After talking about a cup of tea, Li Chengqian's mouth was dry, Cheng Biting Jin and Qin Qiong were dizzy when they heard it, only Liu Min seemed to have gained a little, constantly scratching his head, and his two hands were comparing with each other.

Hearing that Li Chengqian wanted to raise the 50,000 jin iron ingot to a height of five feet through the power of water, the confused Cheng Yanjin rolled a pair of bull's eyes and said disdainfully: "Boy, are you idle and have nothing to do?" What are you doing with a 50,000-pound piece of iron, when you're full? ”

Li Chengqian also rolled his eyes at Lao Cheng, an 'ignorant bandit', looked at Liu Min and said, "Lao Liu, you know the thing about coinage, right?" ”

"Back to Your Highness, the minister knows." Liu Min nodded, although he didn't know what kind of medicine Li Chengqian was selling in the gourd, it didn't mean that he couldn't answer the question.

"So what do you think would happen if we found a three-millimeter steel plate and smashed it with this 50,000-pound iron ingot to turn it into an arc?" Li Chengqian said as he gestured with his hand in front of his body.

"Armor? You mean steel armor? Qin Qiong is not calm, as a general of a hundred battles, the moment Li Chengqian compared, the first impression in his mind was armor.

"Yes, I named this plate armor, which is stamped from a complete steel plate, and different parts are stamped by different molds, such as cuirass, arm armor, wrist armor, etc., and finally these parts can be connected with rivets."

The more Li Chengqian talked, the more excited he became, as a 'can't' control, thinking that those 'tin cans' would appear in his hands more than 700 years in advance, he almost felt like he wanted to collapse with excitement.

Qin Qiong and Cheng Fairy also looked very excited, and the 'tin can' that Li Chengqian said was simply the best equipment to equip the Mo Sword Soldier in their opinion.

The whole body was wrapped in iron sheets, and I was left unmoved by the enemy's knife and axe, just waiting for the time to come, waving the Mo knife in my hand, and for a while, people and horses were broken, and flesh and blood were flying.

The eyes of the two old killers had begun to glow with blood, and they gently ****ed their lips like bloodthirsty demons, staring at Liu Min deadly: "The surname Liu, tell me, can this thing be drummed out?" ”

Liu Min frowned and said, "There should be no problem, it's just ......"

"Hey, I don't like to talk to you like this, okay is okay, no good is no good, what's the matter with a deflated belly." Cheng Fairy was anxious, and as soon as Liu Min squeaked, the old man immediately complained.

"Lao Liu means that there is not enough steel." Li Chengqian couldn't get used to seeing Cheng Fairy bullying honest people, so he took over the conversation on the side.

Cheng Biting Jin's eyes glared, no matter whether it was reasonable or not, he shouted loudly: "If you don't have it, don't you have a new steelmaking method." ”

Li Chengqian looked at Cheng Lao Xiang helplessly for a long time, and finally said angrily: "The iron ore in Chang'an is all transported from other places, and the total amount is only a little, so what kind of refining?" ”

This time it's Cheng Cheng's turn to bite the gold and not squeak, Li Chengqian is right, he doesn't even have the raw materials to refine a fart.

Datang now uses the folk primary smelting, where iron ore is smelted into pig iron or wrought iron, which is then purchased by the government and transported to Chang'an or other workshops that need to smelt iron.

Therefore, raw materials are a big problem, although the steel degree is very fast with crucibles, and iron ore is used, but because of the problem of transportation, raw materials still cannot keep up with consumption.

Cheng Yanjin has been immersed in the prison during this time, and he is clear about the situation that the steelmaking workshop will stop work from time to time to wait for materials, and now Li Chengqian said that the old goods really can't say anything against it.

Just when Li Chengqian and the others were scratching their heads, Qin Qiong slammed the armrests of the chairs: "Make a sample first, if it is really as His Royal Highness the Crown Prince said, let the defense effect, I will personally go to ask Your Majesty, I would rather mobilize the government army than ensure the supply of raw materials." ”

"In this way, Cheng Qian thanked Uncle Qin." Someone went to tell the old man that it was naturally better than going by himself, so Li Chengqian gave Lao Qin a very serious salute to express his gratitude.

Speaking of which, it can basically come to an end, Cheng Yanjin didn't wait for others to speak, and directly diverted the topic, and said to Li Chengqian: "Boy, when the business is over, remember to make a set of this girl's clothes according to the figure of the fourth child tomorrow." ”

"What clothes? This is the Prince's East Palace......" Li Chengqian blinked his eyes and looked at Dugu Yufeng, not knowing which way Lao Cheng was crazy.

"What is the East Palace not the East Palace, just a set of clothes." Cheng Yanjin didn't listen to Li Chengqian's explanation at all, and said with a grin: "Your little fourth sister likes it, why should you be a brother." ”

Li Chengqian nodded helplessly, knowing that Lao Cheng is notoriously difficult to beat, if he doesn't agree, maybe this old man can do something, maybe he will kidnap the tailor of his prince's East Palace.
