I'm Already Invincible, but It's up to You to Decide Whether I'm a Villain or Not?

My name is Xiao Ran, a time traveler. In this world of immortality, I am so invincible that I can only pass the time by sleeping. From the initial ignorance of survival, to the accidental journey to the path of demonic cultivation, and now... Looking at the three realms, I am afraid that those who can take my move have not yet been born. Being invincible is so lonely, especially for a demon cultivator like me who just wants to live a stable life. But the righteous monks seemed not to let me go, and even tried to kidnap me morally. Morality kidnaps a demon cultivator? Things seem to be getting interesting...
