"On selling by the pound?"

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

Yan Liben observed the spinning wheel in front of him, such a spinning wheel did seem to be more labor-saving.

But if it is really used, it is unknown whether it is really as Li Zheng said.

Li Zheng said: "I have to test this textile machine several times, whether it is good or not, if it is easy to use, let's make a few more." ”

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

There are a lot of processes to be done before making cotton into cotton cloth, first of all, the cotton is opened, and then the tension is pressed, and the process of combing the cotton wool out of the fiber is also called carding, which is a very cumbersome and troublesome process.

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

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

The sliver is again subdivided into thinner, thread-like patterns wound around a tube.

The sliver is twisted with a spinning wheel, that is, the sliver is further thinned, stretched, and twisted by 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 the cotton thread, this process is similar to rubbing hemp rope.

It's just that the fibers of cotton are finer and can fit with various fibers commonly used by people.

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

The cotton thread is intertwined with the linen, so that the cotton thread can be made with enough toughness to cut.

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

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

This is its own secret ingredient and the core technology of the cotton business in the future.

I don't plan to tell anyone about this technology until cotton is widespread.

It's a strange experience to have knowledge that is not available in this era.

On top of the overriding 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 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 knowledge is too luxurious for the Tang Dynasty, who is now able to eat well.

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

Li Zheng stopped pressing cotton in his hand, "Invite General Qin Qiong in." ”

Pack up the cotton and twists on the table, pick up the kettle resting on the small tandoor, and pour two cups of hot tea.

Qin Qiong came all the way from the entrance of the village, Li Zheng looked at the visitor and said with a smile: "The general hasn't seen you for a long time." ”

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

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

"In the blink of an eye, these children in Chang'an have grown up." Qin Qiong sighed, looking at the tea on the stone table, other people's families may use good wine and food to entertain guests, but Li Zheng's hospitality is a cup of tea, which makes people feel not rude, but it will not make them feel too attentive.

Qin Qiong likes this feeling very much, and rarely moves around among the powerful in Chang'an, also because as soon as he walks, people will bring wine and food to entertain.

Qin Qiong prefers Li Zheng's cup of hot tea, picks up this teacup that looks a little strange, and feels a lot warmer after taking a sip.

Putting down the teacup, Qin Qiong saw that the twisted cotton on the side still had some hemp rope and wooden sticks, "You are ......?"

Li Zhengchang sighed and said: "I will do some needlework when I have nothing to do, and now that the weather is warm, I also made some clothes a few days ago." ”

Qin Qiong smiled silently, "A dignified seven-foot man would still do such a thing." ”

Li Zheng said helplessly: "In fact, needlework is also a pastime. ”

Qin Qiong pondered Li Zheng's words.

Li Zheng said again: "The main thing is that he is too idle. ”

"Your food supplement method has been used by the old man, and Doctor Sun will come to Chang'an every three or five days to visit the old man's condition, and the effect is very good."

The best effect of dietary supplements is perseverance, and whether the effect is good or not depends on the 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 to replenish blood, and recently the aunts in the village who have just given birth will also drink some brown sugar water."

"You know all kinds of crafts, and you also know medical skills, and your poetry can be said to be unparalleled in the world, and you shouldn't be able to say such things."

"The Great General means ......"

Qin Qiong said in a low voice: "What the old man said is what you said, the earth dragon turned over, the Jiangnan Province was flooded, and now many officials in the court said to you that it was a lie. ”

"They believe it or not."

Qin Qiong glanced around the horse circle and said in a low voice: "If Your Majesty wants to arrest you, the old man will personally arrest you and put you in prison." ”

Li Zheng said with a smile: "There is really such a day to trouble the general." ”

Standing up, Qin Qiong left the horse circle and walked all the way out of Jingyang Village.

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

Qin Qiong walked on Suzaku Street, surrounded by people's discussions, and after tea and dinner, there was always a group of people in the neighborhood who gathered together and muttered in a low voice.

A vegetable farmer said: "It is said that Li Zheng, the concubine today, said that Jiangnan will be flooded, and the dragon will turn over." ”

"Really, fake."

"It is said that it is said by Li Zheng, the current concubine, do you think it is true or false?"

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

"I heard that many officials in the DPRK and China impeached Li Zheng for his evil words to confuse the public."

Someone whispered: "Do you think Li Zheng's prophecies will come true?" ”

"If Li Zheng really said it, is Li Zheng still human?"

"Of course it's not a human being, it's a fairy."

"It is said that Li Zheng is dying."

The farmer who bought vegetables asked in a low voice, "Leak the secret of heaven before you die?" ”

The aunt on the side said, "Do you know what happens when people die? ”

The farmer said, "Yes......"

The aunt then said: "Go to heaven and be a fairy." ”

The farmer said, "Isn't a dead man dead?" ”

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

Someone immediately said, "Of course it's not an ordinary person." ”

"Then it's okay, after the ordinary person dies, he is dead, and after the ordinary person dies, he ......"

The farmer said, "Then it's not a man, it's an immortal." ”

"Aren't immortals human?"

"Of course the immortals are not human anymore."

Everyone nodded in agreement.

A restaurant in Chang'an Pingkangfang.

Lu Dongzan walked into a room without moving.

Satisfaction sat in this room, and there was no girl in the room.

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