A Cultivator's Modern Life

A Qi once transmigrated to a world of cultivation. She kept her strength hidden and lived peacefully for over three hundred years. Once she'd secretly maxed out her level, she slipped back into her original world and decided to try different things in life, starting with becoming a teacher. This is a very laid-back story, mostly about the quiet rhythms of everyday life. It's also wildly imaginative, with the protagonist trying out all the things she's ever wanted to experience.
