There are two ways to deal with stubborn donkeys, one is to smooth the hair, and if you smooth the hair, it will be good. The other is to wake him up, with the momentum of Mount Tai pressing the top, give him a head-on blow, and if he is stunned, he will naturally be obedient.

"Do you know the method of filling steel? Do you know the crucible steelmaking method? "Obviously, Li Chengqian chose the second way: 'beat him up'.

"Steel-filled method? Crucible steelmaking method? Liu Min's eyes flashed with countless whirlpools, and he didn't understand what Li Chengqian was talking about.

"What about blast furnace iron? What about converter steelmaking? What about electric furnace steelmaking? How many do you know? Li Chengqian asked reluctantly, ignoring the fact that these methods could not be achieved in Datang at all.

It is a bit embarrassing to use a thousand or hundreds of years of knowledge to fool an ancient, but I have to say that it feels really good. Seeing Liu Min staring at a pair of confused eyes, Li Chengqian's heart was finally calm.

"Your Highness, Your Highness, these methods you mentioned, how much iron and steel can be produced." Liu Min was really shocked, listening to Li Chengqian's list of several steelmaking methods, although he didn't know how to refine it, he still didn't know how to make it.

"The daily output is 100 tons, oh, it's about 200,000 catties (for the convenience of calculation, I won't count it as 16 taels)." Li Chengqian recalled the daily output of the blast furnace of more than 200 cubic meters of the Hanyang Iron and Steel Plant in the Qing Dynasty in later generations, and said casually.

"Bang dang", Liu Min sat on the chair and wanted to stand up, if his legs were hard and his body didn't move, he even fell back with the chair and fell to the ground.

But the old guy didn't seem to care, he got up from the ground in three or two, his face flushed and asked, "Your Highness, Your Highness is not wrong?" A year or a day? ”

"One day, 200,000 catties a day." Li Chengqian stretched out a finger and emphasized it.

With a "cluck", Liu Min finally couldn't bear Li Chengqian's 'stick' and fainted directly.

"What are you doing in a daze, you don't want to save people." Seeing that he seemed to have really caused trouble, Li Chengqian couldn't help but pray secretly in his heart, hoping that Liu Min would not have cerebral hemorrhage, myocardial infarction and other problems.

Otherwise, if you kill a master who will be a prison master in three sentences, you will have to be peeled off by the old man when you go back.

But fortunately, the things that the ancients ate were relatively good, all green food, without any additives, preservatives, fertilizers and the like, so it didn't take long for Liu Min to recover under Wang Chenghu's care.

After taking a long breath, he said to Li Chengqian with red eyes: "Your Highness, Your Highness, let's also get electricity, let's make steel!" ”

"Think beautifully, but also electric furnace steelmaking...... You can now master the steel filling method, and this palace will personally ask your father for the title of county prince. Li Chengqian snorted, rolled his eyes and said.

Now Li Chengqian understands that this Liu Min is a typical technical freak, and in the words of later generations, he is a 'technical Diao'.

But Li Chengqian didn't expect it, this time he really met a stubborn donkey, Liu Min shook his head and said: "Your Highness, if you don't want a title, you just want to know how to make steel in an electric furnace." ”

Li Chengqian felt that his feet hurt very much, but he smashed it himself, and there was no way, no one could blame him.

After thinking about it, he discussed and said: "Lao Liu, this meal should be eaten one bite at a time, right, no one can eat a fat man in one bite, how can you learn to run if you don't learn to walk, right?" ”

"But the minister is already so old, I'm afraid I won't be able to see that day at all." Liu Min said sadly.

This is a strange thing, Li Chengqian was forced by Liu Min to really have no tricks, so he had to divert the topic: "Old Liu, do you know anything that can withstand high temperatures and can't be burned by molten iron?" ”

"What is Your Highness going to do?" Liu Min's mind was all on the new steelmaking method that Li Chengqian said, and asked a little absent-mindedly.

"Have you heard of molds?" Li Chengqian asked tentatively.

Li Chengqian, the industry or handicraft industry of the Tang Dynasty, does not know what extent it has developed, so he can only ask little by little.

"Mold?" Liu Minxian was confused, and said after a while: "Your Highness wants to mint money?" ”

"No, what am I looking for you to do when I mint money." Li Chengqian sighed at Liu Min's brain hole, and said: "You just said that there is no such fire-resistant thing, and this palace plans to make it into a mold and use it for arrowheads." ”

"The mold that can hold molten iron ......" Lao Liu fell into deep thought, and after a long time, he raised his head and said slowly: "The minister can't guarantee this matter, can you let the minister try it first." ”

"Yes, is ten days enough?" Li Chengqian nodded, and finally heard the most satisfying and reliable sentence today.

"Three days is fine. If it doesn't work out in three days, the minister can only say that there is nothing he can do about it. Liu Min said matter-of-factly.

People who engage in technology are good at this, one is one, two is two, and they still brag and don't fool.

"It's important to do your best." Li Chengqian instructed again, and then asked Wang Chenghu to hand over the three-edged arrow dug out of the pig's head to Liu Min: "If there is a suitable material, make a mold according to its appearance, can it be made?" ”

"As long as the minister finds the right material, the mold is fine." Playing with the three-edged arrow in his hand, Liu Min pondered for a moment and said.

"Okay, then you're busy, Bengong is gone." Looking at Liu Min, who had lost his soul, Li Chengqian knew that if he didn't leave, this guy would definitely ask about electric furnace steelmaking.

"Uh, again, sit down a little longer, Your Highness, it's rare to come once." Liu Min's words are more false and how false they are, so that people will know that they have other plans when they hear it.

"Another day, there are other things to do in this palace." Li Chengqian got up from the chair, ignored Liu Min's retention, and said as he walked.

There is still a butt of things to do when I go back, how can I have time to talk to an old man here, the most important thing is what happened to Wu Chen and that 'chivalrous girl'.

The gossip fire in Li Chengqian's heart can no longer be endured, and he just wants to quickly arrest that guy Wu Chen and ask him well.

"By the way, you have the new metrics here, right?" When he walked to the door of the workshop, Li Chengqian suddenly remembered something and turned his head to ask.

"Yes, the first standard ruler was made by the minister himself." Liu Min was originally a little bent and straight, and said angrily.

"That's good." Li Chengqian nodded and said, "If there is time to hit a few small wheels with a diameter of five centimeters and a centimeter and a half thickness......

Li Chengqian said while gesturing, and roughly told Liu Min about the appearance of the iron wheel.

"It's not a big problem, but it takes a lot of effort to build, what does Your Highness want?" Liu Min thought about it for a moment and thought that he could do what Li Chengqian requested.

"It's still three days, you can fight as much as you can in three days, and this palace is useful."

If there are arrows, it is natural to have a bow, and Li Chengqian wants to know how strong the six-stone bow can be after adding the eccentric wheel.
