The night passed, and the lights in the study were cut off I don't know how many times. Xia Hongsheng rubbed his sour eyes, turned his head to look at Yuexian, who was asleep on the edge of the table, pulled the blanket covering her for her, and then sorted out the pile of drawings and words on the table.

If this continues, you have to be short-sighted. Xia Hongsheng rubbed his eyes, but he didn't dare to be short-sighted, in the future life, he was a thousand-degree ultra-high myopia, and it was easy to cross, if he was not myopia, he had to protect his eyes.

Thinking so, I did a set of eye exercises.

But I can't help but think in my heart, I don't know if there are many myopic people in this era, what should I do if I have myopia. I don't even have myopia glasses, how inconvenient life is!

Just thinking about it, he suddenly felt a slightly cool and soft touch covering his eyes, and the slight coolness penetrated through the skin, which made Xia Hongsheng feel refreshed.

"I'm awake." Xia Hongsheng said with a smile, knowing that it was Yuexian who woke up.

"Childe can't stay up late like this." Yuexian said while gently rubbing Xia Hongsheng's eyes and helping Xia Hongsheng do eye exercises.

"Didn't you think that you finally got the inspiration, and you got it all in one go, and then forgot about it." Xia Hongsheng said with a smile: "I went directly to the academy, just in time to catch up with breakfast." There's a lot more to it. ”

Xia Hongsheng didn't care about resting, took the stack of papers that had been sorted out, and went straight to the academy. He'd have to take these things to the bandstand and see if they can make them. After all, not all the things that Xia Hongsheng has transformed are correct, and they still need the brainstorming of Letai and others, pointing out the mistakes or infeasible places, and modifying them to become things that can be made in this era.

When I arrived at the college, it was just in time for breakfast, and the students were coming out of the dormitory building and rushing into the cafeteria after freshening up. I bought a basket of xiaolongbao and gave a bowl of porridge for free, which cost a total of two cents. The cafeteria is free for the chairs and gentlemen, but Xia Hongsheng does not count himself in this. Besides, the meals in the college cafeteria are really not expensive, even if you choose those dishes with big fish and meat, it will cost dozens of dollars at most, not to mention those ordinary ones. In short, even students from very poor families do not have to worry about not having enough to eat in the college, and moreover, every dish in the college is very delicious, and there are many work-study positions, so when poor students arrive at the college, they can be self-reliant and change their poor life.

As soon as I sat down, I saw several people from the music stage entering the cafeteria together. Several people fed their own meals and came to sit down. Seeing Xia Hongsheng here, they also greeted each other.

"Mr. Le, I'm looking for you again." Xia Hongsheng sat in front of the music stage with a bowl, took out those drawings, and said, "You can take a look at these objects." ”

Letai is also an informal person, immediately put down the chopsticks and freed one hand, pinched the oil horn with one hand, took the stack of papers with the other, and looked at it while eating.

"This thing ......" the musician looked at it for a while, and said, "It looks like it's used to weave cloth?" But how is it so big? ”

"Not bad! Not bad! Xia Hongsheng saw that the music platform could see that it was used for weaving, and immediately rejoiced: "It is used for weaving, this thing is a kind of large spinning wheel, which cannot be driven by manpower, and must be driven by water power at the water's edge. ”

"What?!" Not only the music stage, but also a few people who heard it were also surprised.

Xia Hongsheng nodded and said to everyone: "Not only this spinning wheel, but also the spinning machine, which can also greatly improve efficiency." I have learned before that with today's means of spinning and weaving, one person a day, only five or six catties in the sky, a piece of cloth is difficult to make, and if this kind of machine is used, not only saves manpower, but also can spin and weave at least hundreds of catties of cloth every day! Think about it, if this kind of thing were made, how much cloth would be produced in that day? If there are more quantities, the price will naturally become cheaper, so that the people of Datang will no longer have to worry about having no clothes to wear! ”

Letai looked down at the illustrations and words on the papers, and asked, "Chief, what is this?" ”

Xia Hongsheng leaned over to take a look and saw that it was the drawing of the wooden box type flower machine.

"This thing is called a flower machine, and it is used to play cotton." Xia Hongsheng said to everyone: "Cotton is a very good spinning and weaving material, which is softer and more comfortable than linen, and it is also easier to grow. What's more, cotton can be used as a filler to seal into clothing and make a padded jacket, which is very cheap, but the effect of keeping warm is no less than good fur. If cotton can be grown and popularized, it will enable the people of the world to wear clothes that do not slump and not be frozen in winter. ”

"Oh? Is there such a thing? Yan Xiangshi looked at Xia Hongsheng in surprise.

"Gentlemen also know that when I was born in a poor family, I was most afraid of wintering when I was a child. In winter, I had to wrap the ragged linen clothes at home again, but I was still frozen and almost stiff. Although Shengsheng will no longer suffer from the cold, there are countless cold people in the world, where do they have the money to get good fur to keep out the cold? And with this cotton, as long as the cotton is harvested, elastic and soft, and sewn into the clothing, you can get a better cold protection effect than the best fur. If it's too cold, just fill it with more cotton. Cotton is not difficult to grow, it can be grown in the field where crops cannot be grown, if there is such a thing, then the people of the world do not have to suffer from the cold as me! Xia Hongsheng said to everyone.

Gavinda brushed his beard and said, "If it is really as the mountain chief said, then this thing is of great benefit to the people!" But I don't know where to find this cotton? ”

"Cotton came from Tianzhu and Dashi, and it was mostly planted in the Western Regions, but not in Datang." Xia Hongsheng said: "People don't know that it can be used for weaving and keeping warm, and it is planted in the Western Regions, and it is also used for ornamentation, which is really a tyrannical thing!" ”

"Why don't you report this to Your Majesty?" Yan Xiangshi was very excited and said.

"Sir doesn't know, although I asked someone to buy a few boxes of this cotton from the Western Regions, it still needs to be opened, and it must be played before it can be used to twist and weave cloth, or fill it to make a cotton jacket." Xia Hongsheng said to everyone: "This wooden box-type popping machine has not been made, and I can only use the soil method to pop it out less, and I haven't taken care of it now." Xia Hongsheng said: "Mr. Yan, rest assured, wait for me to pop some out first, make some finished products, and then report to Your Majesty, so that Your Majesty can see the benefits of this thing." ”

Everyone nodded their heads, and the musician put down the stack of papers, saying that he wanted to take a closer look at it while there was no class. (To be continued.) )
