After listening to Xia Hongsheng's words, Li Shimin looked at Xia Hongsheng very curiously and asked, "This is full, I know Xia Qing's idea." The pen "Fun" Pavilion www.biquge.info this one is warm...... How so? ”

Xia Hongsheng replied: "Weichen does know something that can solve the problem that the people have nothing to protect themselves from in winter, if this thing can be done, it will also solve the problem that the Tang Dynasty soldiers cannot fight in the winter in the bitter cold land of Liaodong." It's just that this thing needs to be processed, and it can't be used directly, and the equipment used in this processing has not been done yet. ”

"Oh?! What is it?! Li Shimin was immediately very excited, much more excited than listening to Xia Hongsheng's explanation of naval warfare thinking.

"Cotton, commonly known as white stacks." Xia Hongsheng said to Li Shimin: "This thing was originally produced in Tianzhu, brought into the Western Regions by merchants, the world does not know its value and function, so it is only because its flowers bloom like a ball of white clouds, and for ornamental purposes, in the Western Regions, a little planted, in my land of China is not planted, even there are, but there are only a few large households, as ornamental." ”

When Li Shimin heard this, his face showed a slightly puzzled look, he thought for a while, and said, "Bai Diezi...... Why does it sound familiar? ”

Xia Hongsheng heard Li Shimin say this, thought about it, and guessed again: "This thing is now a specialty of the Western Regions, and it is very likely that someone has paid tribute to His Majesty." ”

Li Shimin nodded, thought for a while, and said, "Let's go, Xia Qing and come with me." ”

After that, Li Shimin got up and left Hanyuan Hall and took Xia Hongsheng out.

"When I heard that Gao Jianwu was building the Great Wall today, I was angry, and I summoned all the generals in the army, saying that they could use firearms to attack it, and they were not afraid that he would build the Great Wall. I wanted to hear if Xia Qing had any unique opinions, so I summoned Xia Qing to come, and I was not disappointed. Li Shimin said with a smile as he walked: "After hearing Xia Qing's words, I don't feel annoyed at this time, but I also feel funny." Hehe, when I heard that Xia Qing could find a way to solve the problem of going to Liaodong to keep out the cold, my anger suddenly disappeared, and I became happy again. ”

Xia Hongsheng said with a smile: "It is an honor for Weichen to solve problems for His Majesty. ”

"Hehe, don't talk to the family." Li Shimin said with an unprecedented smile, it was really unprecedented, this was the first time Xia Hongsheng had heard him say this.

Seeing that Xia Hongsheng was puzzled, Li Shimin smiled again: "I listened to Changle, and Ke'er and Qingque said, you spent a lot of effort in the academy to make this hot air balloon, just for Changle's words." I am very relieved that you can have such a heart for Changle. Changle, this girl, has been sensible since she was a child, kind and gentle, among my daughters, my favorite is this daughter, you can treat her like this, it really makes me breathe a sigh of relief! ”

While speaking, Li Shimin took Xia Hongsheng to a corridor in the imperial garden, and after stopping, he pointed to a few plants in the garden outside the corridor and said, "Xia Qing take a look, but this thing?" This is a contribution from Gaochang Kingdom in the Western Regions, and it seems to be said to be replaced by white stacks. ”

Xia Hongsheng took a look at the past, and sure enough, he saw a few cotton plants planted under the root of the wall!

"That's it!" Xia Hongsheng suddenly said happily: "Your Majesty, this is cotton." Cotton is full of treasures! It has a large output and low production cost, and it is used to spin silk and weave cloth, the price is very low, and the people can afford to wear it. Cotton can be made into fabrics of various specifications, is strong and wear-resistant, can be washed and ironed at high temperatures. The cotton absorbs and dehumidifies quickly and makes it comfortable to wear. In addition, it is not used to spin silk and weave cloth, just sew the cotton into the clothing or bedding as a filling after processing, it can resist the cold, the more cotton is filled, the warmer it is to wear and cover, a quilt is filled with more than ten catties of cotton, and one or two such quilts are enough to survive the cold winter. Its cold protection effect is much better than that of fur and the like. In addition, cotton can also be used as an oilseed. Your Majesty, if you can take six or seven catties of treated cotton, sew it into your clothes as a sandwich, and then wear it on your body, even if it is winter in the bitter cold land of Liaodong, it will not be a problem! ”

"What?!" Li Shimin was taken aback, and hurriedly asked, "Does Xia Qing have processed cotton in his hands?!" ”

"Wechen ordered the caravan to collect some cotton from the Western Regions before, and now it is drying at Wechen's home in Jingyang. As for the equipment for handling cotton, Wechen has also designed it, and is working together with the cooperation of the gentlemen of the academy to see if it can be made. Once it's made, it's ready to be processed with cotton, and then it's time to spin and weave the fabric. Xia Hongsheng said to Li Shimin.

Li Shimin was obviously very anxious about this, and hurriedly asked, "How is the progress?" If necessary, I can ask the Military Aircraft Workshop to assist Xia Qing! ”

"I have already made a machine for processing cotton, but there is a slight flaw in it, and Mr. Le Tai of the Academy has begun to improve it again, and if you think about it, the perfect machine will be made soon. After the equipment for processing cotton is made, it can actually be spun and woven in the current way. It's just that today's means are inefficient, and Wechen has designed a large device that can carry out large-scale textile production, which has yet to be made and tested. After the cotton processing machine comes out, Weichen can process some cotton first, so that His Majesty can see the effect. ”

"Good!" Li Shimin nodded: "Goguryeo is a city based on the mountains, easy to defend and difficult to attack, if the war cannot be carried out in one go, once August passes, as for September, the grass will be dry and frozen, and it will be difficult for the soldiers and horses to stay for a long time, only the class teacher will return to the court." If the ability of this cotton to keep out the cold is as Xia Qing said, then there is no worry at the end of the year! ”

Xia Hongsheng nodded: "Weichen will make a cotton elastic machine as soon as possible and dedicate it to Your Majesty!" ”

"Good! It is worthy of Xia Qing! Hahahaha! Li Shimin laughed heartily: "I should drink with Xia Qing to congratulate him!" ”

After that, he ordered Wang De to go and arrange the banquet.

Xia Hongsheng stayed, because the weather was not too cold, so the two sat opposite each other in the pavilion in the imperial garden, put a pot of wine and a few dishes in front of them, and began to talk.

Li Shimin asked a lot about the equipment that Xia Hongsheng said, and Xia Hongsheng also explained it to Li Shimin in detail.

"There's a hot air balloon in the front, a bouncy machine and a hydro spinning wheel in the back." Li Shimin drank a glass of wine and sighed: "That hot air balloon, I saw it with my own eyes, and after the military aircraft workshop learns it, I also want to use it to fly in the sky and enjoy the magnificent rivers and mountains of my Tang Dynasty." The flower machine and the water-powered spinning wheel, although I only heard about it, I didn't see it, but after listening to Xia Qing's description, it should also be used in the world for the benefit of the people. I was amazed to think that the college had already made such a contribution in less than a year. ”

"Hehe, Your Majesty, no matter what the academy makes, it is to make our Tang Dynasty better, and it will be handed over to the imperial court." Xia Hongsheng knew Li Shimin's careful thinking, so he smiled and said, "However, there are only two requirements for the academy. ”

"Oh? Let's hear it. Li Shimin put down his wine glass and asked.

Xia Hongsheng said with a smile: "First, the world must know that it comes from the academy, and second, naturally you have to apply for a patent first, that's all." ”

When Li Shimin heard this, he laughed loudly. (To be continued.) )
