Chapter 1183: Medicinal Valley

"You've finished reading it?!" asked Elder Wan Zheng in shock. "You've already remembered all the formulas here?"

Chu Liuyue nodded.

Actually, she had already finished reading it a few days ago, but she only had time to return the book today.

A portion of it was eighth-grade formulas, and the other portion was ninth-grade formulas. They were all for superior pills.

Elder Wan Zheng looked at her doubtfully. "I know that you have a photographic memory, but… You've understood the ninth-grade formulas here?"

One had to know that the difference between an eighth-grade pill and a ninth-grade pill wasn't that simple. The number of herbs used in a ninth-grade pill was many more than the number of herbs used in an eighth-grade one. Additionally, its steps were complicated and had an extremely high requirement for techniques.
