Lin Feng is an ordinary country boy with a kind heart. Because he supposedly possesses the secret of a "primordial Dao body," the immortal master of the Qingyun Sect comes in search of immortals and slaughters every man in his village before his eyes to "sever his mortal ties." Lin Feng himself is taken back to the sect to serve as a cultivation cauldron, where he suffers endless humiliation. In the depths of despair, he unexpectedly awakens an ancient demon soul hidden within him and sets out on a path of devouring all things and exacting vengeance at will. He finally understands: on the path to immortality, if you don't eat others, they'll eat you.
