"The benefits of a steel crossbow are many, first of all, it doesn't have to take a lot of time to dry in the shade like a wooden crossbow in terms of production time." Nearly an hour later, a steel crossbow with a crossbow arm completely made of steel was held in Li Chengqian's hand and explained loudly.

"Second, it's easy to maintain. Whether it's in the alpine snow field or in the forest desert, this guy doesn't need to be deliberately maintained. As long as it doesn't get raw, it will be a reliable long-range weapon for soldiers at any time and anywhere. Gently flicking on the arm of the steel crossbow, Li Chengqian continued to introduce.

"Thirdly, its accessories are standard, as long as they are the same model, no matter which production batch, their parts are interchangeable." Li Chengqian said as he placed the steel crossbow on the ground and fiddled with it, and when he got up again, the steel crossbow had been dismantled into a pile of parts.

"The fourth and most important point." Li Chengqian paused, and said proudly: "Datang has a new steel production process, we don't have to worry about the lack of steel in the future, the crucible steelmaking method can make our steel output reach tens of thousands of catties per year, of course, the output of iron ore must keep up." ”

Standing in front of the old man, facing more than a dozen veteran ruffians of Tiance Mansion, Li Chengqian spoke eloquently and confidently.

"You're right, Liu Min, who will be the supervisor, is indeed worthy of a reward, and the county man's title is indeed a little low." Li Er motioned to the guards to bring over the steel crossbow parts on the ground, and after playing for a while, he said to Li Chengqian.

"Father Emperor Mingjian!" Although Li Chengqian is full of confidence, it has not yet reached the level of bursting, and the necessary respect in front of the old man must be maintained.

"Ming, Mingjian, wait for me to finish speaking, and then you will talk." Li Er waved his hand to interrupt Li Chengqian and continued: "From now on, the prince will return to the palace to study behind closed doors for a year, if he dares to step out of Yiqiu Palace (the official name of Lanruo Temple) half a step...... Let's go and stay at Soshoji Temple. ”

The old man's words were like a thunderbolt on a sunny day, directly smashing Li Chengqian into a daze, and a fiery heart immediately became cold.

Li Chengqian, who was in a daze, knew that he was really finished this time, and he finally provoked the old man after tossing again and again.

But what can be done, no one else in Datang understands these things except himself, and he can't hold Jinshan to ask for food.

And if Ren Datang develops according to the past history, then it is not in vain that he wasted an opportunity to cross, as a 'four haves' otaku crossing the public, how could Li Chengqian waste such an opportunity.

But now it's all in vain, the grounding order has been issued, and the old man won't change his mind easily, so let's honestly wait to go back to 'Lanruo Temple' and squat in prison.

Anyway, the grounding is like that, the so-called policies and countermeasures, the gentlemen in Chang'an City have been grounded by their own Lao Tzu a lot, which one is not released after three or five days.

The most important thing is that Li Chengqian thinks that the main reason why the old man locked himself up should be for the 'lost' tea cup.

If you honestly hand over the teacup, it is estimated that it will not take a few days to be free, but ...... Do you really have to pay it?

"Brother, what do you think, you're so engrossed, people have called you three times." Li Li's glutinous arrival made Li Chengqian come back to his senses.

It's been locked up for three days, and it's very lonely, if it weren't for Wu Mei's little Lori and eldest sister Liqing, it is estimated that she would have been suffocated.

"Here, Yuzhang, what about them? Why didn't I come with you? Li Chengqian looked up at Li Liqian and said with a smile.

"They're playing." Sitting on the chair brought by the waiter, Li Lizhen and Li Chengqian sat side by side, looking at the blue sky in a daze.

"Actually, you don't have to come every day, I'm just grounded, not confined." After a while, Li Chengqian turned his head to look at his quiet sister and said lightly.

"Brother, you have a really big heart." Li Lizhi chuckled, and she could vaguely see a trace of the gentle temperament of the eldest grandson queen in her.

"You have something to say." Li Chengqian shook his head and smiled.

"Father said that if you don't admit your mistake again, you will really be imprisoned for a year." Li Lizhi frowned lightly and said with concern.

"You're going to intercede with me again?" A trace of inexplicability flashed in Li Chengqian's eyes.

Lizhen's sister has been close to him since she was a child, and she likes to share any words or secrets with him, and when she was punished by the old man, it was most likely her sister who interceded for herself, but ...... Li Chengqian shook his head and let go of what he shouldn't think.

"No, this time it was the queen mother who interceded for you, and I overheard it on the side." A hint of cunning flashed on Li Lizhi's face.

"Don't do such things in the future, beware of being caught by your father and beating you." Li Chengqian scared Li Li with a tiger face.

"No, my father loves beauty the most." Li Lizhi wrinkled her beautiful little nose and said coquettishly.

After some laughter, Li Lizhi suddenly said seriously: "Brother, let me ask you something." ”

"Tell me, what's the matter?"

"What do you think of Little Four?" Li Li's delicate little face was mysterious, and she asked quietly.

"Little four? If your fourth brother hears this, he will have to sue you. Li Chengqian said aloud and said with some amusement.

"It's not the fourth brother, it's the little four, Cheng the little four!" Li Lizhi corrected Li Chengqian's thinking.

"Cheng Xiaosi?" Li Chengqian's mind flashed the image of a beautiful little Lori holding a small sword and standing in front of everyone.

"That's right. It's Cheng Xiaosi, what do you think of her. Li Lizhen's eyes flashed with the light of eight seals, and she asked repeatedly.

"Little girl, what can I think." Li Chengqian glanced at Li Liqian, a little confused about what she wanted to do.

Could it be that the dolls of Datang are so precocious? Only eight or nine years old do you know how to find a match?

"Are you going to marry her in the future?" Li Li asked persistently, quite a little bit unreaching.

"Go, go, play, you little girl knows something." Hearing Li Lizhi mention marrying Cheng Xiaosi, the first reaction in Li Chengqian's mind was the eight big characters of 'starting in three years, the highest death penalty'.

"No, brother, you must not marry her, you know, you must promise me." Li Li's delicate and immature little face was very serious, and at the same time said very seriously.

"No, what the hell is wrong with you today? I haven't even done the crown ceremony now, is it too early to study marrying a daughter-in-law? For Li Liqian's entanglement, Li Chengqian was very helpless.

This sister is good at everything, usually quiet, gentle and lovely, but if she really wants to be petty, it is really a headache.

And this little girl suddenly made such a fuss, what is going on?!
