Mu Lingyun had never seen this medical pharmacopoeia before.
But in her mind, there was a complete one.
After signing in to become the Valley Master of Medical Saint Valley, the system had crammed all this information into her brain.
Thus, after looking at it for a while, she felt somewhat bored.
After closing the medical pharmacopoeia, she looked at the Great Elder and said, "You must have read these books before, right, Great Elder? Don't you find it boring to go over them so carefully again?"
Mu Lingyun expressed that she herself wasn't too keen on reading them.
The Great Elder paused, then spoke, "These books, when read again, are actually completely different from the first time! When you reread them, you'll notice many things you didn't pay attention to the first time."
Mu Lingyun listened, without expressing agreement or disagreement.
To review the old and know the new, perhaps that's what the sage was talking about.
