P.S. The protagonist is a complete scumbag, selfish to the core.
Chen Yan is an utterly unscrupulous cultivator of evil arts.
He has only one goal in life: survive, grow stronger, and achieve immortality.
Morality, reputation, the righteous path’s opinion of him? Not worth half a cent.
After he transmigrates to this strange world where spiritual energy is poisonous, cultivation is like drinking poison to quench your thirst.
One wrong step, and his body mutates, his mind vanishes, and he becomes a man-eating monster beyond the city walls.
Only the great formation around the city can suppress the corruption and give cultivators and martial artists a brief respite.
Chen Yan hides inside the city, posing as a street patrol constable and passing himself off as the most unremarkable ordinary man.
Disciples of the righteous path uphold their principles and follow their precepts, living in constant fear.
He, on the other hand, has mastered the System’s Corpse Refining Evil Art.
Helpless beggars, lone gang members, thugs with no one to back them up...
A few disappear at night, and no one ever investigates or cares.
He doesn’t specifically target villains.
He targets whoever is safest to kill and least likely to expose him.
No matter how vicious a monster is, once dead, it makes excellent material for corpse refinement.
No matter how ruthless the righteous path may be, they’d never suspect that the honest, down-to-earth Constable Chen has a System inventory piled high with ferocious corpses.
The great formation can keep the monsters outside the city at bay, but it can’t stop him, hidden among the crowds.
Keep your head down, grow stronger, build up your resources.
Once his wings are strong enough, no mere city can hold him, and no righteous sect can stand in his way.
He is destined to tread the path to immortality, one step at a time over a pile of bones.
What’s morality worth? Corpse refinement and immortality are better.
