Fantasy: I Became a Big Boss, but I Don't Know Anything

What kind of exercises are you doing? I will become a big boss after I leave the mountain. Do I need to practice? Besides, I'm so handsome, why do I want to kill myself? I don't rely on those useless things when people travel through time in the halo of the protagonist. Also, I can destroy the sun, moon, and stars with one move. This feeling of invincibility is so satisfying. This is my life, hahaha! This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
