Even if Lin Xianyu has the ability to never forget, it is only theoretical knowledge, knowledge in books.

When it came to practice, it still made Lin Xianyu work hard and suffered a lot.

Because many medicinal herbs are actually quite similar.

What's more, to recognize medicinal materials, it is not only necessary to know each medicinal material, but also to have medicinal properties, as well as collocation, and which kind of product is the best and has the strongest medicinal properties.

Lin Xianyu stayed in the pharmacy all day, and he only knew one-tenth of the medicinal materials.

However, Dr. Li is already very satisfied with Lin Xianyu's progress!

"It's getting late today, so let's stop here. Go back as soon as possible, lest your mother worry about you. ”

Dr. Li watched the sunset and interrupted Lin Xianyu, who was immersed in learning.

Although Lin Xianyu usually doesn't look very reliable, when he is studying, he is really attentive.

"Then I'll come back tomorrow." Lin Xianyu realized that this small medicinal herb actually contained so much wisdom!

If you use it a little wrong, the medicine that saves people can become the medicine that kills people!

After Lin Xianyu returned home, he directly improved the incense powder recipe slightly, especially some of the medicinal materials used, and only changed it after consulting the master.

After the change, this incense powder recipe, although the foundation is still Yueniang's, but the kernel is completely different.

Not only is there nothing harmful to the human body in this incense powder, but it even has a small amount of beauty and beauty effects.

Perfect recipe!

Lin Xianyu took this recipe and went to Mrs. Lin to offer treasure.

"Mother, look at this." Lin Xianyu gave Mrs. Lin the incense powder, the original recipe and the improved ones sent by Yueniang.

"Powder?" Mrs. Lin looked at her daughter with some surprise.

"The envy fish is older, and it is also the age to dress up and be pretty." After Mrs. Lin finished speaking, she opened the incense powder but was flustered.

I was even more surprised to see the two different squares before and after.

You must know that the Lin family has a business of rouge gouache, because women's money is the best to earn.

The taste of this incense powder is very unique, elegant and fresh, and it seems to be absent.

And this recipe, the one before the improvement, is not very precious, and the materials used are mediocre.

Because this incense powder has nothing special except for a special fragrance.

But after the improvement, it is completely different, not only the materials are precious, but her daughter also used clumsy brush words to mark which medicinal materials play what role, and finally explained that it has the effect of beauty and beauty.

"Envy fish, where did you get this recipe?"

During this time, Mrs. Lin's rouge shop business was trying to enter the high-end market, and she lacked a product that could be held in town, so her daughter was sent to the door.

Lin Xianyu told Mrs. Lin what happened today.

Twenty taels to hire a doctor for a year, no matter how you calculate it, it is a good deal.

If it weren't for Dr. Wang's troubled affairs and his reputation was greatly damaged, let alone twenty taels, even if it was fifty taels, he might not be able to hire them.

"Xianyu, you did a good job, this recipe is very useful, but I can't give Yueniang a commission for your improved recipe."

Mrs. Lin nodded only after hearing that her daughter promised to cover all the medical expenses and promised to give Yueniang a commission, otherwise it would be a kind of danger to take advantage of others.

"These two recipes are already two products, the original one can go to the low-price market, and the one you have improved is just the main high-end product of Wudiexuan."
