City of Sin (Yanyu Jiangnan) - Vol 1 Chapter 47: Mountainsea

Demons in Academy of Light are described as vile, dark, cruel, evil, impure, and a whole lot of other things. At least, that’s how they’re portrayed in the game—a sacred land where demons and dark energies aren’t supposed to exist. That’s how it was supposed to be... So what the hell am I supposed to do now? Thanks to my rotten luck, my soul ended up possessing the lowest-ranking demon, the one who dies at the very beginning of the story... I’m screwed! I have no other options left... If I want to survive, I have to kill the protagonist.

[Are you crippled?][Did your fiancé break the engagement?][Did you lose your family to a demon attack? Are you the last surviving member of your clan, seeking revenge?][Does your family look at you with pity because you're the only one without any innate spiritual roots?][Are you tired of being told that you're a 'waste of resources'?][Are you stuck with no way to progress? Are you tired of being weak and helpless?][Well, have no fear! This Supreme Master is here to help you!]

Lu Chang’an cultivated the reincarnation of immortals for two generations, and in the third life, An Wengou reached the Nascent Soul stage, solved the mystery of the reincarnation stele, and then practiced the mediocre ancient health-preserving skills.

Avoid fighting and fighting, operate steadily, and form good relationships with people.

After a long cultivation career, I got acquainted with growing characters, upright leaders, celestial beauties, demon giants, evil cultivators, thousand-year-old monsters, behind-the-scenes chess players…

Watch the ups and downs of the world, the ebb and flow of the tide.

Unknowingly, it has become a living fossil in the world of cultivating immortals, an evergreen tree through the ages.

…………

Mortal flow, stable, pseudo-longevity, decisive killing, and normal three views.
