SHE IS A TEACHER

"MEOW"

[Alright, so I read about this on one of those books at the Elixir Making section. I found this record about a sorceress that suits your description. This sorceress was dubbed as the best potioneer of the Milennia.]

Janus first gave them a few words of introduction about the other party.

He even put some effort into giving a pause for a few more seconds to add more drama to his introduction before continuing.

"MEOW"

[She had been in Magus Academia for a long time, before being reported as a missing person way back 30 years ago. Then after around 10 years ago, she went back to Magus Academia as if nothing happens.]

"A sorceress that is good at Elixir making who left Magus Academia and reported back at school 20 years ago. Hmmm... Interesting."

Mu Lingxi said to herself as she nodded her head.

It was unsure whether it was pure coincidence or not, but the other party's appearance and disappearance fitted to their timeline.
