People in Datang have been expelled from school

Chapter 438 Immortal?

"Sell by the catty?"

"That's right, Jingyang's cloth output will be very high in the future, and the quality will be very good."

Yan Liben observed the spinning wheel in front of him, this kind of spinning wheel really looked less labor-intensive.

But if it is really used, it is not known whether it is really as Li Zheng said.

Li Zheng said: "I have to test this textile machine a few times to see if it works. If it works, let's make a few more."

Yan Liben nodded and said, "I'll let the people from the village come over and try."

Before the cotton is made into cotton cloth, there are many processes to be done. First, the cotton must be loosened, and then stretched and pressed. The process of combing the cotton wool into fibers is also called carding. This is a very cumbersome and troublesome process.

It's also very boring to do, and you have to repeatedly operate this process.

The carded flakes are then passed through a smaller roller again to become slivers.

The sliver is again subdivided into thinner strands that are wound around a tube.

The sliver will be twisted with a spinning wheel, that is, the sliver will be further thinned, elongated, and then twisted by a machine
You can get cotton thread. Of course, if you want to make cotton thread, you have to wind it with hemp to increase the toughness of cotton thread. This process is similar to twisting hemp rope.

It's just that the fibers of cotton are thinner and can be matched with various fibers commonly used by people.

Because cotton thread is easy to break, this era without yarn can only be replaced by hemp.

Cotton thread is interwoven with hemp, so that the cotton thread has enough toughness to cut.

To explain it from a more scientific point of view is to increase the strength of chemical fibers.

Of course, Li Zheng didn't intend to tell Yan Liben about this.

This is my secret recipe, and it is also the core technology of the cotton cloth business in the future.

I don't plan to tell others about this technology before cotton cloth is popularized.

It is a strange experience to have knowledge that is not available in this day and age.

On top of knowledge, Li Zheng felt that the height of his vision was a high point that the people of the Tang Dynasty during the Zhenguan period could not reach in their entire lives.

In fact, this high point is very simple, it is just the mathematics, physics and chemistry of the system and some microscopic knowledge.

And this kind of knowledge is too extravagant for Datang, who is only able to eat enough now.

Du Hu sent meat and vegetables to Long Wujun, and when he came back on horseback, he said, "Chang'an Order, General Qin Qiong is here."

Li Zheng stopped pressing the cotton in his hand, "Please invite General Qin Qiong in."

Clean up the cotton and twigs on the table, pick up the kettle on the small clay stove, and pour two cups of hot tea.

Qin Qiong walked all the way from the entrance of the village. Li Zheng looked at the visitor and smiled and said, "Long time no see, General."

Looking at Li Zheng, Qin Qiong said: "When I saw you for the first time, you were still a little doll that an old man could pick up with one hand. I didn't expect you to grow so big."

Li Zheng handed a cup of hot tea and said, "I will be an adult next year."

"These children in Chang'an have grown up in a blink of an eye." Qin Qiong sighed, looking at the tea on the stone table, other people's homes might use good food and wine to entertain guests, but Li Zheng's hospitality is a cup of tea, which makes people feel It's polite without being overly courteous.

Qin Qiong likes this kind of feeling very much. In Chang'an, he seldom walks among the rich and powerful, and it is also because when he walks around, people will serve him food and drinks.

Qin Qiong liked Li Zheng's cup of hot tea better. Picking up this strange-looking teacup, she felt a lot of warmth in her internal organs after taking a sip.

Putting down the teacup, Qin Qiong saw the twisted cotton and some hemp rope and wooden sticks beside him, "You are..."

Li Zhengchang sighed and said: "I do some needlework when I have nothing to do. Now that the weather is warmer, I even made some clothes a few days ago."

Qin Qiong smiled silently, "A man of seven feet tall still does such a thing."

Li Zheng said helplessly: "Actually, needlework is also a kind of pastime."

Qin Qiong thought about Li Zheng's words.

Li Zheng said again: "It's mainly because I'm too free."

"Your food tonic method has been used by me all the time. Miracle Doctor Sun will come to Chang'an every now and then to check on my condition. It works very well."

The best effect of food supplements is to persevere. Whether the effect is good or not depends on time, and there is no immediate effect.

Qin Qiong said again: "Your brown sugar is also very good."

"Brown sugar is indeed a good thing for nourishing blood. Recently, aunts in the village who have just given birth will also drink some brown sugar water."

"You are proficient in all kinds of crafts, and you also know medical skills. It can be said that poetry and prose are unparalleled in the world. Someone like you should not say such things."

"The general's meaning is..."

Qin Qiong said in a low voice: "The old man said what you said. The earth dragon turned over, and the south of the Yangtze River is full of floods. Now many officials in the court are talking about you to confuse the public."

"They believe it or not."

Qin Qiong glanced around the horse enclosure, and said in a low voice: "If His Majesty wants to arrest you, this old man will personally arrest you and put you in jail."

Li Zheng said with a smile: "It's really such a day to trouble the general."

Standing up, Qin Qiong left the stables and walked out of Jingyang Village.

Today's Chang'an once again caused an uproar because of Li Zheng's words.

Qin Qiong was walking on Zhuque Street, surrounded by people's discussions, and after dinner, a group of people in the neighborhood always gathered together and murmured in a low voice.

A farmer who sells vegetables said: "It is said that today's son-in-law Li Zheng said that there will be floods in the south of the Yangtze River, and there will be things like earth dragons turning over."

"real or fake."

"It is said that the current son-in-law Li Zheng said it, do you think it is true or not?"

"It is rumored that even Yuan Tiangang is ashamed of Li Zheng's abilities."

"I heard that many speech officials in the court impeached Li Zheng to deceive the public."

Another whispered, "Do you think Li Zheng's predictions will come true?"

"If it's true that Li Zheng is talking about it, is Li Zheng still human?"

"Of course it's not a human, it's a god."

"It is said that Li Zheng is dying."

The farmer who was buying vegetables asked in a low voice: "Did you leak the secret before you died?"

The aunt on the side said, "Do you know what happens after a person dies?"

The farmer said, "Yes..."

The aunt went on to say: "I will go to heaven and be a fairy."

The farmer said, "Isn't a dead person dead?"

The aunt whispered: "Do you think that the rumored Li is just an ordinary person?"

Someone immediately said: "Of course not ordinary people."

"Then it's okay, ordinary people are dead after death, and extraordinary people are dead after death..."

The farmer said, "Then it's not a human being, it's a fairy."

"Aren't immortals human?"

"Of course immortals are not human beings."

Everyone nodded in agreement.

A restaurant in Pingkangfang, Chang'an.

Lu Dongzan walked into a room with no expression on his face.

Xin Xin is sitting in this room, there is no girl in the room.

Lu Dongzan walked into this room and closed the door. The girls around were full of curiosity about this room, and looked a little disdainful.
