Chen Lin transmigrates into the body of a disciple of an evil cultivation sect. He plans to become the greatest evil cultivator under heaven by practicing the Shadow-Devouring Evil Art, only to discover that every shadow he devours grants him the righteous cultivation techniques of its owner.
And so...
In the eyes of evil cultivators:
"This man hides his true nature extremely well. He seems to practice evil arts, but is actually a saint of the righteous path!"
In the eyes of righteous cultivators:
"This young man is untouched by worldly grime and possesses boundless merit. He is the future leader of our generation!"
Chen Lin:
"No, I really just want to be an evil cultivator!"
