Bei Yutang said nothing, but put a box of rouge into water to dilute it. After continuously diluting it, he soaked the rice paper in the rouge water for five hours. Then he dried the rice paper with fire and asked Xue Qian to check it.

Xue Qian indeed found Su Cuihong on it.

"I can prove it with the method you used that day."

Bei Yutang shook her head. "It took five hours to soak. You had to make sure everything was safe. Even if it's proven, they could just say you tampered with it during those five hours, or even switched it up. There are too many ways to go about it to make it impossible to prove."

"So what should we do?"

Bei Yutang pointed at the herbs in front of him and said, "Use them."

Before Xue Qian could react, Bei Yutang said, "You can make better rouge than Gu's and sell it at a cheaper price. Do you think they will still buy from Gu's?"

Xue Qian's eyes lit up, "You're right."

"What you have to do now is to make rouge that is better than Gu's Company at the lowest cost. This task is left to you." Bei Yutang patted his shoulder lightly and said solemnly.

"What about you?" Xue Qian looked at her.

"I have things to do, too."

In the two rooms, Xue Qian was studying the formula of rouge, while Bei Yutang was opening other skin care products.

Gu Pianran wanted rouge and wanted to expand her territory through cosmetics, so she used all kinds of ice creams and cosmetics products to completely block her path.

"Ming, are there any skincare products suitable for this era in the system's store?"

Bei Yutang did know some of the materials used in modern skin care products, but in those backward times, these things were difficult to find and even more difficult to extract.

For example, although she knew aloe vera was good, extracting it would be very expensive, and current technology was not up to the level of modern industry. Most importantly, aloe vera was rare, and she didn't have the time to cultivate it now.

If possible, she would rather buy the formula from the system's merchandise.

【have. 】

"How many points are needed?"

【200 points.】

"Buy one."

Ming seemed surprised by her straightforwardness and couldn't help but ask, "Aren't you worried about losing points?"

He knew how much she valued points, and she would feel heartbroken if she lost one or two points.

"formula."

Bei Yutang didn't bother to talk to him.

Soon an ancient recipe appeared in Bei Yutang's mind.

Bei Yutang's eyes lit up after reading the recipe. An ancient recipe seemed to have sparked her inspiration.

Ming saw Bei Yutang quickly changing the original recipe, creating various recipes.

Ming looked at her in surprise.

Sure enough, Bei Yutang is Bei Yutang and will not suffer any loss at all.

The two hundred points were well spent.

Bei Yutang looked at the formulas he had modified. Whether these formulas were feasible would only be known after experiments.

In the following days, everyone devoted themselves to researching beauty and skin care products.

Xiao Moer helped her mother, Daixiang helped Xue Qian, and she was solely responsible for food and clothing at home. The three of them were doing various experiments in the room with peace of mind.

Xue Qian tried again and again to create a rouge that was cheaper and more effective than Gu's, which was undoubtedly a huge challenge. When he learned that Bei Yutang had successfully developed a lipstick, Xue Qian became even more anxious.
