Shao Qingyuan smiled. "I've never learned it."
"Huh?" A question mark slowly appeared in Gu Yundong's mind.
"Do you still remember the medical book you gave me?" He was referring to the medical book that Gu Yundong had copied from Song Dejiang. At that time, Gu Yundong had given it to him so that he could read it and remember the herbs inside. If he saw the herbs in the mountains in the future, he would not miss them.
At that time, Shao Qingyuan remembered the book after reading it once. It made Gu Yundong feel defeated.
After that, the book was left with him.
