I, the Great Immortal, Am Reborn as a High School Student?

I am also a world-famous Great Immortal, and there is no great cultivator who does not respect me. But you actually let me be reborn as a high school student, what are you doing? Well, for the sake of the goddess being my default wife, I will bear with you for a while... I just want to show off and don't want to cause trouble. You scumbags don't have the foresight to show up at my door. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
