Zi Xu smiled and let go.

Qian Zhenzhen went back and changed into a dress similar to Zi Xu, holding a horse whip in her hand.

"I'll talk to my father and see if he is going."

"it is good!"

The two came to Master Qian's study, Master Qian was reading a book in his arms.

Zi Xu glanced at him, and Master Qian was actually watching the planting of coarse cotton.

"Father, Zixu is here. She wants to see the coarse cotton. Give me the key to the big warehouse."

"Well...what? Zixu is here? Quick, I have something to find her!"

Zi Xu felt that the two men had similar temperaments.

Lord Qian saw Zixu and smiled: "I happen to be looking for you. You have a lot of land. Can you improve the coarse cotton?

I have now found a way to produce more tribute cotton, you see if it works. "

He took out a few pieces of paper in the crypt of the desk and handed it to Zi Xu.

Zi Xu took it and looked at it, and it turned out to be a grafting method.

This method is generally used on fruit trees, but it has never been used on cotton.

Just change the main stems of white peach cotton and red peach cotton, and new varieties will grow if they survive.

But this way the total amount of labor is large, and the survival rate is not high.

Zi Xu shook his head: "This won't work. You can only plant a small piece of land, one mu at most."

"That's it." Master Qian was disappointed.

He has lost a lot of weight now, so his expression can be seen clearly, no longer like the fleshy ball before.

Qian Zhenzhen pouted: "You have been fooled again, haven't you learned the lesson about the seed last time?"

Master Qian glared at her, "Didn't I want to try it? If there is more tribute cotton, the people will be able to afford it.

You won’t wake up from sleep at night. "

Zi Xu felt soft, the Lord Qian really loved his daughter.

Qian Zhenzhen smiled and said nothing.

Zi Xu said: "Let's take a look at the coarse cotton first. Now Cheng Guian has a monopoly on the fabric. Your coarse cotton can solve my big problem."

"Really?" Master Qian's eyes lit up and the loss on his face disappeared.

Qian Zhenzhen asked, "Are you going?"

Master Qian nodded: "Of course, I will also go, walk around!"

The three of them rode horses, and Master Qian was still relatively large, but he rode very sensitively.

The three came to the Qian's large warehouse, which covers a large area and many people are guarding it.

Although things are not very valuable, they need to pay attention to fire prevention.

Opening the door of the large warehouse, Zi Xu walked in. There was a skylight on the roof, which could let light through by poking it open with a stick.

Zi Xu tore open a sack, revealing the gray-brown coarse cotton inside.

If you look closely, it is really cotton, but the fiber cloth is white and thicker, and it is not soft.

If it is not soft, there will be gaps, and the cold wind will not keep you warm.

Zi Xu smiled and said: "These coarse cotton grows exactly like malnutrition without growth."

Qian Zhenzhen didn't understand this: "The people now use this kind of coarse cotton. They buy it and soak it with water, then fish it out and beat it with a wooden stick.

Knock it into a ball and then even out, so that you can make a quilt. "

Zi Xu nodded: "Well, this is also a way, better than nothing."

Master Qian asked: "These coarse cottons are all with seeds, so the selling price is very cheap, don't look at it so much, it didn't cost a lot of money!"

Zixu touched his chin and asked Tian Tian secretly: "Do you think these cottons have the value of improvement?"

Tian Tian said: "In fact, it is a good way to soak it with water. If you use a softener to soak, you can omit the step.

Add bleach, just a little bit more than the cotton. "

Zixu doesn't like bleach, and thinks pure natural things are good.

"Do we have that softener?"

"do not have!"

"No, you say a ball!"

"Stupid host!"

"Huh! You are smart, but you take it out!"

Tian Tian snorted: "The reward task is for nothing? You offer a reward."

"A reward? Can I offer a reward too?"

"Nonsense, this is a platform. You are not only the person who takes the task, but also the customer. Of course you can."

"Wow... can I just go and offer a reward for what I want?"

"Almost, but with shielding, you can't change things that are harmful to the world."

Zi Xu rubbed his hands in excitement: "I won't change things that are harmful to the world. What do you think I can use as a red?"

"Dim Sum, the formic acid produced by the ants is a good softener."

Zi Xu nodded: "Yes, but how much can I exchange for a hundred dim sum?"

"This...I don't know, I have to discuss it!"

"Then you can discuss it, hope not to lose, after all, there is a lot of coarse cotton here."

"Got it."

Just after talking here, Qian Zhenzhen gave Zi Xu a push: "What's your expression? It's like seeing gold.

These coarse cottons cannot be sold at a good price even if they are made into fabric. "

Zi Xu looked sideways: "That's because you can't help it. I'll take a hundred jin and go back for the experiment."

Master Qian smiled and said: "Get more, or else you can toss all these coarse cotton, I know now that there is no way to improve it."

Zi Xu thought for a while: "Alright, give it to me, and share the money together."

Master Qian didn't spend much to buy these coarse cotton, and now he still owes Zi Xu money, so he plans to give it for nothing.

"You don't need to divide it. If you make money, the interest on the money you lent to me is ready."

Zi Xu looked sideways: "You will regret it."

Master Qian shook his head: "How come?"

Zi Xu smiled: "Okay, I'll take a hundred catties first, you find someone to pick out the seeds for me."

"it is good!"

Zi Xu hurried home after receiving a hundred catties of coarse cotton.

Tian Tian said: "After talking, Ant-Man said that the snack is too small, ten yuan in exchange for a drop of formic acid."

"A drop? How much cotton can it soften?"

"It's about a hundred catties. The concentration of formic acid is very high and needs to be mixed with water."

"Yes, but we have no utensils."

Tian Tian said, "Don't worry about this, they do."

Zi Xu nodded: "Okay, I'll go to make dim sum immediately, and change ten drops first."

"it is good!"

Zixu went to make dim sum, it was getting dark on a busy day.

After the formic acid was exchanged, Zi Xu was stunned, ten drops? This is not ten liters?

Tian Tian smiled: "The Ant-Man over there is bigger, and your snack is small. Ten yuan is enough for a bite."

Zi Xu haha: "Next time I will make a big snack."

She took out about 100 milliliters of formic acid, mixed it with ten kilograms of water, and then soaked the coarse cotton in.

The coarse cotton is gray-brown with a dirty feeling. Soaked in formic acid, it gradually becomes grayish white. After an hour of soaking, the coarse cotton becomes much cleaner, but it is still not white.

After drying, the elasticity of coarse cotton is much smaller, and it feels particularly like acrylic cotton.

Zi Xu soaked these coarse cotton in normal water and found that it did not absorb much water.

In this way, the phenomenon of moisture absorption and compaction of cotton will not occur.

Tian Tian asked: "How is it? Did it succeed?"

Zi Xu touched his nose: "Half of success!"
