A pair of white and slender plain hands were immersed in a copper basin of clean water. Liu Sichun first wet his hands, then wiped them with this piece of soap, and then washed them with clean water.

Throughout the whole process, I learned to use the first piece of soap in the human world under the guidance of Li Chen.

Soon, Liu Sichun was surprised to find that although this piece of soap seemed greasy, it had strong cleaning ability. After washing his hands, his hands were clean and refreshing, and many greases and dirt disappeared.

Although Liu Sichun's hands were already very clean, she rarely felt this refreshing feeling. She could truly feel this piece of soap and clean up all the oil that was invisible on her hands.

"Your Highness, this thing is so magical!" Liu Sichun's surprise performance attracted Wan Jiaojiao's envy.

No woman doesn’t like beauty or cleanliness.

If His Highness hadn't been here, she wouldn't have been allowed to go and experience it in person in the morning.

Li Chen smiled and said, "The biggest function of this thing is to cleanse and remove dirt, especially for some oils, which have super effective effects."

"Although wealthy families can bathe with flower dew and petals, these things are destined to be impossible for ordinary people to own. Therefore, using them not only cleans your hands, but also uses them during bathing, but also completely cleans the whole body. The most important thing is that the raw materials for making this product are cheap, simple, and suitable for large-scale promotion."

Liu Sichun was a shrewd businessman, and Li Chen just started to look a little bit, and immediately she thought that this thing would definitely be something that could sensation the market as soon as it was released.

"Where does Your Highness come from such a treasure?" Liu Sichun asked in surprise.

"It seems to be in the book."

With a smile and casually swearing, Li Chen said: "Every woman in the world loves beauty. Can this thing win the hearts of women in the world?"

Liu Sichun said excitedly: "Take a baby!"

As she said that, she frowned again, sniffed her hands, and hesitated: "It's just a little bit of beauty. After washing it with it, there is still a smell of oil."

"It's okay, just add some floral powder."

Liu Sichun said happily: "Your Highness, this thing can bring incredibly generous profits..."

"You just do it."

Li Chen said lightly: "I will give you the recipe and teach you in detail how to make it. Your Liu family is responsible for all the production and sales. You are professional in this regard. This is only a little requirement for me. The net profit is 70% of the Ministry of Revenue."

Liu Sichun said without hesitation: "This is the Liu family that has taken advantage of the situation. The private daughter thanked His Highness."

After saying that, Liu Sichun looked at Li Chen with a shocking look and said, "First it is sweet potatoes, then this soap. What else can Your Highness not do?"

With a chuckle, Li Chen chose to continue to maintain his mysterious and tall image in front of Liu Sichun, so he did not respond to this issue at all.

Next, Li Chen spent an hour teaching Liu Sichun how to make soap.

The principle of soap is simple and the production process is not complicated. As long as you know the method and procedure, it is difficult to fail.

In addition to Liu Sichun's talent, he has completely mastered the time in one hour.

Then Liu Sichun could no longer sit still and immediately went back to make arrangements.

After Liu Sichun left, before Li Chen could breathe a sigh of relief, he saw Wan Jiaojiao flashing big eyes full of desire. Even Gong Huiyu, who was looking for a new book next to the bookshelf, also looked over from time to time.
