I can't remember the title of this one I was reading, "My Master is..." something like that? The MC is a super strong woman from our time who ends up in a cultivation world where she trains her student. But she really doesn't have any sort of magic powers, she's just really strong. Her student is a swordsman who's a good cook and he keeps progressing from stupid things she says even though she has no idea what she's talking about. There's also this other guy who's a senior cultivator who reincarnated from our time but she's way stronger than him.

I really can't remember the title...
