I'm a useless prince, so what if I know a little bit of chemistry?

"Is it finally starting? This time, we can come in handy."

Chun Fang glanced at Qin Jiaojiao with unusual excitement in his eyes.

Qin Jiaojiao covered her mouth and smiled, jokingly saying, "Sister is really happy, but the Marquis won't be able to see her so happy."

"You stupid girl, you actually made fun of your sister."

Chun Fang's face turned red after hearing what Qin Jiaojiao said. He gently pushed Qin Jiaojiao's shoulder but did not refute. He just hoped to see Lin Fan again as soon as possible.

But Qin Jiaojiao did not stop, but continued: "It is easy to find a priceless treasure, but it is hard to find a lover. Sister, I saw it clearly before. The way the Marquis looked at you at that time was not the way an ordinary host looks at a maid. The Marquis is interested in you, sister. If you don't hurry up, don't let others get there first."

Chun Fang was stunned, as if she was recalling the scene where Lin Fan came to save her. It seemed that her eyes were indeed different, and she couldn't help but feel a little amorous.

But then she found that Qin Jiaojiao was looking at her with a smile, and she understood. She stretched out her jade finger and touched Qin Jiaojiao's forehead, saying coquettishly: "You stupid girl, you only learned some tricks to deceive people in the brothel."

Qin Jiaojiao smiled even more happily, stuck out her pink tongue slightly, and said, "I was just talking, but I didn't expect you to take it seriously. Okay, it's all my fault. I'll apologize to you."

Chun Fang rolled his eyes at the smiling Qin Jiaojiao and said unhappily, "Okay, stop talking nonsense and get ready for action. If you're too late, be careful that the Marquis will spank you."

Qin Jiaojiao nodded and left to prepare.

Chun Fang, however, stood there distracted.

Just as Qin Jiaojiao said, the way Lin Fan looked at her that day was very different, and Lin Fan had been quite close to her recently.

Could it be that the Marquis really has intentions?

Or am I just overthinking?

For a moment, Chun Fang was confused and all kinds of emotions surged in his heart.

"Sister, it's time to go." Qin Jiaojiao shouted in the yard.

"Oh, okay, coming I come!" Chun Fang adjusted his mentality and walked out the door.

It was already evening, and in the residential area, many people could be seen strolling around after dinner.

Next to these wandering people, there were two girls in plain clothes, constantly selling things.

It was Chun Fang and Qin Jiaojiao.

The two set up a stall on which they placed soap and some dirty clothes.

Next to the dirty clothes, there is a bucket of water.

There were quite a few people gathered in front of their stall.

Most of them were there to watch the fun and had no interest in what the two were selling.

However, there are also some people who, although they don’t understand why, are gradually attracted.

Chun Fang rubbed his hands on a piece of lard, and when he felt that his hands were greasy, he picked up a piece of soap and started washing his hands.

"This is soap. You can use it to wash clothes, hair, and hands. It is definitely much better than soap nuts, and it doesn't have any odor. You can all take a look."

When Chun Fang finished washing, there was indeed no oil stain on his hands, which surprised the people around him.

"Sure enough, it is much better than soapnuts."

"But this is more expensive than soapberry, right?"

"Little girl, you have to go to the Shen family's main residence to sell these things that rich people use. We can't afford them here."

Amid the excitement, some people were talking, some were advising Chun Fang and Qin Jiaojiao to change the place to sell their products, and some were staring at Chun Fang and Qin Jiaojiao with lustful eyes.

"What kind of soap is this and how much is it?" Someone walked forward a few steps and pointed at a bar of soap and asked.

"One tael of silver." Qin Jiaojiao stretched out a finger and said.

The man picked up a bar of soap, looked at it, weighed it in his hand, and then asked, "It's not very heavy. It won't become useless after a few uses, right?"

"How is that possible? A piece like this can at least last for a month or so." Chun Fang said.

"One tael of silver is not expensive. Give me one piece first." The man took out one tael of silver and said.

"Wait a minute." Qin Jiaojiao said.

The man said dissatisfiedly: "What's wrong? Don't you want to sell it? Isn't this bullying?"

Qin Jiaojiao waved her hand, stretched out five fingers, and said to the man who wanted to buy soap, "Sir, you misunderstood. It's not that we don't sell it, but we will give a discount to the first five customers who buy it. If you want to buy it, you only need to pay half a tael of silver."

When the man heard this, he retracted his hand, changed it, and handed it to Qin Jiaojiao, saying, "Half an ounce is not expensive. Just think of it as paying for a lesson."

"Here is your soap, take it." After taking the money, Qin Jiaojiao handed a soap to the customer and said softly.

The man took the soap, looked at it, and then looked worried, muttering, "I hope it works well. If not, I'll just think of it as a waste of money."

Someone nearby saw the man's dirty clothes and came over and said, "Brother, why don't you try it here? If it works, you won't lose anything."

The man thought it made sense, so he looked at Chun Fang and said, "Can you lend me your water?"

Chunfang nodded and said, "Of course, feel free to use it."

"Hey, that won't do. What if they put something special in the water?" the man stopped the man and said.

The man hesitated for a moment, then thought it made sense, and asked, "What should I do? I'd better go back to the inn and wash."

The man turned to leave.

At this time, an old man came out, stopped the man, and said, "Don't worry, my yard is right next to you. I can just go get a bucket of water."

The old man seems to be popular.

When the old man finished speaking, someone had already taken the initiative to help him fetch water.

Not long after, an old man and a child came over carrying a bucket of water.

The old man looked at the people around him and said, "Everyone knows me, Old Jintou, right? You all know what kind of person I am, so I won't say much. Let's see the effect of this soap. If it works, we can each buy a piece. It's not easy for these two girls, so just consider it as a help."

"I still trust Uncle Jin."

"Just listen to Uncle Jin. If it works well, we'll buy it."

"Yes, try it and let us see the effect."

Listening to everyone's words, the man nodded and agreed.

"Okay, I'll give it a try first."

The man did not take off his clothes, but put a dirtier corner of his clothes into the water and dipped it, then looked at Chunfang and asked, "What next?"

"Rub the soap on the dirty area and start rubbing it. After rubbing for a while, rinse it off with water." Chun Fang said.

"Oh, good."

The man heard and did as he was told.

After rubbing for a while, the man found a layer of foam and continued rubbing.

When the man feels it is almost done, he rinses off the foam with clean water.

When I saw the corner of the clothes, I found that they were indeed unusually clean.
