Tang Shanzhi was very confused by Li Chengqian's decision, and wanted to know why His Royal Highness the Crown Prince, who had grown up together since childhood, was so keen on steam engines.

Although it is said that almost all of the Maison now orders this 'stupid and stupid' thing, and also uses some of the profits generated by it, if it is important, Comrade Xiao Tang thinks that this is enough now, and there is no need to miniaturize it at all.

As for shrinking this thing to one-fifth of its original size, and actually getting the title of a marquis, Xiao Tang felt that Li Chengqian must be crazy, and he was incorrigibly crazy.

Left and right is just a machine, although it can drive the press, it can drive the grinding disc, it can also drive the spinning wheel and many other things, but it is a machine after all, and it seems completely unnecessary to pay so much attention to it.

Li Chengqian saw from Xiao Tang's performance that he was disapproving of the steam engine, and in order to add some motivation to him, he got up and walked to his side: "Do you want to accept my kindness, let's talk about it later, how about going out for a walk with me now?" ”

"Gao Ming, you better give me an explanation, whether this matter is reliable or not. Let me tell you, my father ......" Tang Shanzhi followed Li Chengqian's side, nagging while walking, moving out of his old son for a while, and moving out of his mother for a while, in short, in one sentence: I don't want to go!

Li Chengqian walked quietly in front of him, listening to Xiao Tang's nagging, and only stopped when he came to an open field, pointed to the distance and said: "From here to the east, about forty-five miles is Chang'an, how long do you think we can get there at the earliest?" ”

"It's almost there!" Although Tang Shanzhi is a scholar, he can still ride horses, and he just came from Chang'an in the morning, so Li Chengqian's problem is not difficult for him.

Li Chengqian nodded noncommittally and continued to ask, "What if it's a 3,000-strong infantry army?" ”

"It will take about a day to march into." Tang Shanzhi estimated the time and replied.

However, Li Chengqian's question seemed endless, and as soon as he got the answer, he asked again: "How long will it take for the 3,000-strong infantry army to arrive in Luoyang?" ”

"This ......" Tang Shanzhi hesitated for a moment, and only said after a while: "If you march in a hurry, you can arrive in three days, and if you march normally, you can arrive in ten days." ”

"One day, this palace says that it can be there in one day, but only if you need to get that steam engine right." Li Chengqian leaned down and squatted down, picked up a stone on the ground, and said while drawing: "According to the current size, you need to make the steam engine have four cylinders, and they can move at the same time, and then I need you to load it on a car." ”

Tang Shanzhi, who was already a little reluctant, could already be sure this time that Li Chengqian was indeed crazy, and His Royal Highness the Crown Prince was driven crazy in this deserted place where birds don't.

How big does a house-sized steam engine need to fit into a car? What kind of car can carry something so heavy? Anyone who can think like this is mentally ill except for a madman!

"If you have anything to say, look at Lao Tzu with that kind of look again, believe it or not, Lao Tzu asked you to guard the city gate?" Xiao Tang's strange eyes finally caught Li Chengqian's attention, and at the same time caused trouble for himself.

However, Xiao Tang also let go, and said to Li Chengqian with a stalk around his neck: "Gao Ming, if you are not crazy, can you tell me, how do you put such a big thing in the car?" What kind of car can carry such a heavy load? Can you still get an iron cart to hold it? ”

"Iron car?" Li Chengqian was stunned for a moment, this is the first time he has heard of this word, but it seems that Xiao Tang is not wrong, and there is nothing wrong with the train being called an iron car.

Thinking of this, he nodded approvingly: "Good knowledge, it seems that Bengong really didn't see the wrong person, you really have a talent for scientific research, and you can even think of making a car into iron, amazing!" ”

"What?" Tang Shanzhi looked at Li Chengqian inexplicably, and his brain was a little short-circuited.

"You're right, I'm going to make the car iron and put that steam engine on it." Li Chengqian, who had a bad stomach, deliberately didn't say it clearly, and the half-truths seemed to be ridiculing Xiao Tang.

This is one of the few pleasures that His Royal Highness the Crown Prince can enjoy in the Tang Dynasty, using the insights of later generations to crush the ancients, looking at their faces with surprised or suspicious expressions, Li Chengqian can get great satisfaction.

Sure enough, Xiao Tang was fooled as expected: "This can't be!" That thing is so heavy, even if it can be put on the car, there is no way to make the car move, not to mention a horse, even if it is a cow...... No, even an elephant can't be dragged along. ”

"Haha......" Li Chengqian looked at Xiao Tang, who was a little angry, and finally couldn't help laughing, and said while laughing: "Good knowledge, good knowledge, you are so cute." ”

...... was so cute, Tang Shanzhi suddenly had an urge to kill.

Damn, if Li Chengqian wasn't the prince, if he didn't have that inseparable female guard by his side, if he really couldn't beat him, Tang Shanzhi really wanted to rush up and strangle him.

"Okay, okay, I won't tease you." Li Chengqian laughed for a while, and seeing that Xiao Tang was a little annoyed and angry, he forced down the smile in his heart and continued: "Don't think I'm joking about the iron car, this thing really has to be done, but all this is empty talk until you get the steam engine, let's study it after you get it all right." ”

"No, you have to explain this matter to me clearly, otherwise Lao Tzu would rather go to guard the city gate than go to the research department." Xiao Tang, who felt that he had been tricked, also came up stubbornly, shaking his head like a rattle.

After being laughed at by Li Chengqian, Xiao Tang also figured out that this top-level gentleman who had played with him since he was a child and grew up seemed to have never said empty words, and everything he said basically became a reality in the end.

In this case, the iron car must not be groundless, and if he is not sure, Li Chengqian should definitely not say this thing.

Based on the above reasons, Xiao Tang felt that it was necessary to listen to Li Chengqian's next plan, if there was really a 'cheap', it would be a good choice to go to the Research Agency to stay for a while.

"Okay, you come with me, let's talk about it." Li Chengqian also felt that he was a little unhappy with the bragging just now, and now that Xiao Tang took the initiative to ask, he naturally would not let go of the opportunity to show off, and dragged Tang Shanzhi back to his hut again.

"Look at this, if there is anything you don't understand, come and ask me." After returning to the small room, Li Chengqian rummaged through the pile of old papers for a long time and found a crumpled piece of paper.
