Nangong Xu walked over, sat down on the chair, feeling helpless.
Baili Xia immediately took off her shoes with a grin, climbed onto the bed, "Master, I'm a bit tired, is it okay if I lie down and listen?"
Nangong Xu looked up at her, wanting to say something but held back.
Baili Xia immediately added, "I won't fall asleep, I'll listen carefully, definitely."
Nangong Xu glanced at her once, then again, and eventually still pulled up a chair to sit by the bed, deliberately showing impatience, "Where did we leave off last time?"
"In the way of traditional medicine, only old and fresh are valued, with time that can be worn but not hurried... Master, why do we need both old and fresh? Isn't that contradictory?"
Nangong Xu stared at her, finally starting to explain quietly.
"Using old in medicinal herbs refers to age, using fresh naturally means the efficacy is best when freshly picked."
