"Gao Ming, what the hell are you doing here?" The eldest grandson was afraid that Lao Li would beat his son, so he asked first.

"Queen mother, Erchen promised her eldest sister a quilt today yesterday, so she is rushing to make it." Li Chengqian, who was helped to the ground by Chunxiao from the chair and stood up, bowed down and said to the eldest grandson.

"Quilt?" Comrade Lao Li walked to the middle of the courtyard, pointed to the messy people around and said, "Are they all making quilts? ”

Seeing Lao Li just coming in and aggressive, Li Chengqian knew that something was wrong, although he didn't know where to make the old man unhappy, at this time Lao Li asked about the quilt, which was just a good opportunity to change the topic.

"Yes, Father, please see." Li Chengqian jumped down from the steps of the door, ran to Lao Li, pointed to a row of palace maids squatting under the porch and said, "They are responsible for tearing off the cotton wool and then collecting it." ”

Turning back to the guard who drew the bow, he said, "His task is to make the cotton wool soft." ”

He also pointed to the two palace maids standing together on the other side: "They folded the soft cotton wool together, covered both sides with pieces of cloth, and sewed them up, so that a quilt was ready." ”

"It's so exciting, just for a quilt that I don't know what to call it, your prince has gone too far, right?" If you want to add to the crime, there is no excuse, Lao Tzu wants to trouble his son, so he can just pull out a reason.

"This ......" Li Chengqian was a little confused, the old man is going to make trouble like that today? Trouble yourself this morning?

looked at my mother, and wanted to give a look for help, but found that the eldest grandson was playing with the cotton wool that had been played, and he didn't care about himself at all.

Under the gaze of Emperor Lao Tzu like a knife, Li Chengqian hesitated for a moment, and said in an old tone: "Father, the son is also worrying about the monarch." ”

"It's 'worrying for the king' again, Cheng Qian, can you change the word?" Li Shimin looked at this son, who was only tall from his waist and abdomen, and didn't know how to describe his mood.

"Father, the son is really worried about the king, you listen to the son slowly explain how it is." If my mother doesn't help, she only saves herself, or it would be too embarrassing to be beaten.

"Say it. If the explanation is unreasonable, don't be afraid to reward your father with 'fried meat on a bamboo board'" Li Shimin took a piece of cotton wool from the eldest grandson's hand, put it in his hand and looked at it, and said lightly.

Empress Eldest Sun watched from the side with a lively attitude, she had heard the saying that she was worried about the king no less than 10 times in the past 3 months, but this kid could mix it up every time, this time she would see if Li Chengqian could have any new statements.

"Father, as the so-called high temple is worried, the people are worried, and the far away rivers and lakes are worried about the king, although the sons and daughters are sick, they also think about it day and night......" Li Chengqian bragged to his head, and a chuckle interrupted his statement.

When I looked up, it was the eldest grandson queen who was laughing, and it seemed that she couldn't stop.

As soon as Li Chengqian said a nonsense thing, it seemed that if Comrade Li didn't reward him, he would be a little sorry for the people of the world.

"If you don't speak well, beware that I will immediately make you copy the Analects a hundred times." His Majesty Li Shimin, the Emperor of the Tang Dynasty, felt that if he let this kid blow down again, he was afraid that the throne would not be enough to reward him immediately.

"Father, it's like this, the son is just doing an experiment, if it succeeds, the soldiers of my Tang Empire will no longer be limited by not being able to fight in winter......." After blowing for a long time, Li Chengqian finally thought of a way to get away with it.

"Go on." When it came to the battle, Li Shimin also became serious, and his expression became more and more serious.

Empress Changsun also showed a worried look on her face, and when it came to the army, if this kid couldn't make up a lie, I was afraid that it would really be difficult to escape a beating.

"Father, this cotton wool can be stuffed into the quilt to keep warm, this has been tried, and there is no problem. So why don't we stuff it into our clothes and make it into a wooden garment to replace the cotton garments worn by the soldiers today? ”

You must know that before the invention of modern down jackets, cotton clothes and pants have always been the main clothing used by the people to keep out the cold, which is enough to prove that Li Chengqian's statement can be completely realized, even if it cannot solve the problem of winter warfare, it is a great achievement to let the people not be exposed to the bitter cold of winter.

"You're going to make a cotton coat?" Li Shimin was also inspired by his son, and felt that if he could really solve the problem of the bitter cold in winter, it would not be a big problem to be woken up once.

"Of course. Father, you see, there is no shortage of weavers here for your sons, why don't you try to make a set for your father now? Li Chengqian is confident in cotton clothes, after all, future generations will rely on this thing for hundreds or thousands of years to survive the winter.

After measuring the size of Comrade Li, the weaver went to make clothes, but Li Shimin looked at Li Chengqian, who was coming to his eldest grandson with a ghostly head and a ghost, and said: "Chengqian, if the cold effect of this cotton clothes and cotton pants is really as you say, how long will it take for you to make enough clothes for 20,000 soldiers?" "It's like talking to an 8-year-old naughty boy.

"Father, this is not a matter of the son-in-law, the son-in-law is just an experiment. How to produce, how much to produce, you should go to the Ministry of Works. Li Chengqian, who was poked by his eldest grandson on the door of his head, hid beside his mother, and he didn't have to worry about Comrade Li's sudden slap, and he couldn't help but speak with a lot of confidence.

"Of course I know to go to the Ministry of Industry, and what I ask is that relying on you, the palace maids, to brush it up little by little, in what year can I brush the cotton wool used by 20,000 soldiers." Li Shimin's hands began to itch, and he really wanted to pull Li Chengqian over and beat him.

"Father, there must be brave men under the so-called heavy reward, I have countless craftsmen in the Tang Dynasty, and my son believes that it should be cost-effective to release an empty viscount and exchange it for a craftsman who can develop a tool for quickly removing cotton seeds, right?" At this time, Li Chengqian and Lao Li were not at all like an 8-year-old child, although they were not as good as the eldest grandson Wuji, Fang Xuanling and other important ministers of the court, but relying on the baptism of the Internet in later generations, some reliable and unreliable ideas could still be come up with.

"You mean the national bounty?" Li Shimin was not sure what Li Chengqian meant, and asked with some doubts.

"No, Erchen thinks that we should first make a reward within the Ministry of Industry and try to keep this matter a secret, otherwise everyone in the world will know that we have the ability to fight in winter, which is not good for us." Li Chengqian frowned and said thoughtfully.

"Moreover, Erchen thinks that in a short period of time, my Datang's cotton output can only meet military needs. Of course, if there is a surplus, we can sell it to the people at a low price through the government-run commercial houses, and the process of taking cotton cannot be easily leaked out in any case. "There is no one in the entire Datang who understands the importance of technical blockade better than Li Chengqian, so before the plan began, he set the tone of secrecy.
