Thinking of this, Shen Yanxiao immediately follows rod's words without saying a word.

The library on the ninetieth floor is totally different from what Shen Yanxiao saw before. There are no mountains of books here, but only potions placed in huge cabinets one by one.

Hundreds of medicines are placed in rows of cabinets. The sun shines through the library window and sprinkles on all kinds of medicines. It is as beautiful as mottled crystal.

Shen Yanxiao's eyes are closely attracted by those potions. Here she sees a lot of high potions that can only be heard in the legend. Looking around, all the cabinets in the whole 90 floors are high potions.

The cheapest price of a bottle of high-level medicine is thousands of gold coins, and the most expensive one is tens of thousands.

Shen Yanxiao roughly estimated that the total value of the high-level medicine placed on the ninetieth floor was enough to buy five cities!

Unconsciously, Shen Yanxiao's hands itched.

If she could get all these potions, she would not have to worry about money for the next ten years.

Rod led Shen Yanxiao through the aisles to a huge wooden door.

Rod carefully tidied up his clothes and then knocked on the wooden door.

"Come in." An old voice rang from behind the wooden door.

Rod immediately opened the wooden door.

Inside the wooden door, there are dozens of huge drug refining tables, each of which is made of the highest crystal stone. On each crystal table, there are expensive drug refining utensils. These utensils have the highest quality. The price of any set is 3 million gold coins.

An 80 year old man was so busy at a medicine making table that Rhode's entry didn't affect him at all. His eyes were fixed on the burning crystal bottle. The handsome young man standing beside the old man took a look at rod and said politely, "mentor rod."

Rod nodded his head and said, "shangguanxiao, you are very early today."

Standing next to the old man is Xiao, the top official in the pharmacy branch.

There was a faint smile on Xiao lengqing's face. When he noticed Shen Yanxiao behind rod, he was slightly shocked.

"Rod, why are you here?" Buried in the potion, the old man slowly raised his head and looked at rod.

"Master price, I'm here to tell you something." Rod is very respectful to the old man.

"What is it?" There was a shrewdness in prise's old eyes. He was one of several pharmaceutical masters of Saint Laurent college, famous for the whole empire of Longxuan. Even Ouyang Huanyu wanted to treat him politely by three points.

Most of the people who can hit the top of their careers are eccentric. Naturally, these medicine masters live in the library for a long time and rarely appear in front of people. Some people have even stayed in the library for five years without leaving half a step. Their research on pharmacy can be said to be a state of demon sealing.

"I heard that Dean Ouyang said before, master, you are willing to find some gifted students to be assistants in the pharmacist branch. I am here to recommend a student to you today." Rhode said respectfully.

"Oh?" Prise looked at rod and then noticed Shen Yanxiao standing behind him.
