He's always so perceptive, but since Li Zhibai doesn't explain, she must have her reasons.
So Xu Chang'an didn't ask. After a light sigh, he seized the opportunity to complain to his teacher, recounting those things he encountered during work as jokes for Li Zhibai.
As a man being an Internal Affairs Steward on Muyu Peak... there really are many inconvenient things.
"Teacher, some tasks are really inconvenient. Speaking of, don't laugh at me, but the days when the senior sisters on Three Officials Rock have their menstrual cycles... I can't help but remember them, since if Ms. Fang is unavailable to deliver items, I have to go." Xu Chang'an looked helpless: "Thankfully, the senior sisters are quite broad-minded and don't mind such minor issues."
The elixirs or items like white silk used by Muyu Peak women during their Gui Water, he could say he's very familiar with them.
Li Zhibai: "..."
Honestly speaking, she didn't really want to hear the words "Gui Water" right now.
