Yinhu knew that if he wanted to succeed, the person with ultimate decision-making power wasn't the Empress, but Zhao Xuanji.So he simply spoke directly to Zhao Xuanji.Zhao Xuanji chuckled and said, "...Chapter 703: The Technology Tree

A pair of fair, slender hands dipped into the basin of water. Liu Sichun first wet her hands and then rubbed them with this bar of soap before rinsing them thoroughly.

Under Li Chen's guidance, he learned to use the world's first bar of soap.

Soon, Liu Sichun was pleasantly surprised to find that although this bar of soap looked oily, it had a very strong cleaning power. After washing his hands, his hands were clean and refreshing, and many oil and grease stains disappeared completely.

Although Liu Sichun's hands were already very clean, this refreshing feeling was something she rarely experienced. She could truly feel that this thing called soap had washed away all the invisible oil and grime from her hands.

"Your Highness, this thing is so amazing!" Liu Sichun's surprised expression caused Wan Jiaojiao to be incredibly envious.

No woman does not love beauty and cleanliness.

If it weren't for your Highness being here, she wouldn't have dared to go there herself earlier to experience it.

Li Chen smiled and said, "The greatest use of this item is to cleanse and remove stains, especially for some oil stains, it has super efficacy."

"Although wealthy families can now bathe with flower petals and other such items, these things are ultimately unattainable to the common people. Therefore, using this [product] not only cleanses hands, but can be used for bathing, effectively cleaning the entire body. Most importantly, its production materials are inexpensive and the process is simple, making it suitable for large-scale promotion."

Liu Sichun was a shrewd businesswoman by nature. As soon as Li Chen mentioned the idea, she immediately grasped that this product had the potential to create a sensation in the market.

"Such a treasure, Your Highness, where did you come by it" Liu Sichun asked in surprise.

"As I read in a book."

With a smile, Li Chen casually replied, "All women in the world love beauty. Could this object win the hearts of all women"

Liu Sichun said excitedly, "It's as easy as taking something out of one's pocket!"

"Speaking of which, she frowned again, sniffed her hand, and hesitated: 'There's just one slight flaw. After washing with it, there's still a faint fishy smell.'"

"It's alright, just add some floral scent powder."

Liu Sichun said with delight: "Your Highness, this thing can bring immeasurable profits..."

"Go ahead and do it."

Li Chen said calmly, "I will give you the recipe and teach you how to make it in detail. The production and sales will be entirely your Liu family's responsibility. You are professionals at this. I only have one request: 70% of the pure profit goes to the Ministry of Households."

Liu Sichun said without hesitation, "This is already a great favor to the Liu family. The little woman thanks Your Highness."

Then, Liu Sichun looked at Li Chen with an astonishing gaze and said, "First, it was sweet potato, and now this soap. Is there anything Your Highness cannot do"

Chuckling lightly, Li Chen chose to maintain his mysterious and tall image in front of Liu Sichun, so he didn't answer the question at all.

Next, Li Chen taught Liu Sichun how to make soap in an hour.

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

Liu Sichun is remarkably intelligent. In just an hour, he has mastered the subject completely.

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

After Liu Sichun left, Li Chen hadn't had time to catch his breath when he saw Wan Jiajiao's eyes, full of longing, blinking at him. Even Gong Huiyu, who was browsing the bookshelves for new reads, would occasionally steal glances in his direction.

Li Chen burst into laughter and said, “I’ll give you two each a piece.”ss the Princess live a thousand, thousand, thousand years!"Li Chen turned his head to look at Su Jinpa, just about to speak.Boom!A deafening roar erupted, and outside the gates of Taimiao Palace, crie...
