There are rumors in the world that the Qingyun Sect's once-in-a-century "Destined Son" is about to appear, but because of a mistakenly delivered secret letter, the poisonous bastard Lu Jin was mistaken for the destined one. Lu Jin, who originally wanted to live alone and wait for death, was forced to get involved in sect battles and the battle between good and evil. While pretending to be a master, he relied on his golden fingers to deceive the whole audience with his "poisonous words". His friends who were jealous of him in the past secretly tried to trip him up, but masters from all walks of life worshiped him. The more he pretends to be, the more he looks like it, and he actually becomes the savior? But no one knows that this "Holy Son" doesn't even know internal skills, and relies solely on his talk and poisonous snakes to support the scene.
