Liang Yuan, the craziest gangster in the underground world of Dongcheng, has gained a reputation in the street with his fists. One day, he accidentally picked up a shabby ancient book while collecting protection fees, and from then on, he had a strange "villain halo system" in his mind.
The system told him: As long as he accepts a disciple and guides him on the path of being a villain, he will be able to obtain heaven-defying rewards. However, Bai Yunyan, his first disciple, turned out to be a confused girl with a horribly stupid nature - she was able to blow up her enemy's house because she forgot to turn off the gas, she was able to control the underworld because she treated the underworld boss as an uncle who asked for directions, and she became a public enemy of martial arts because she sent secret books to the whole world as recipes.
From then on, Liang Yuan lived a frustrating life in which "the system urged me to teach my disciples to be bad guys, but my disciples did good things every time." What's even weirder is that he discovers a shocking secret: the chaos of every era seems to originate from the accidental collision of a "confused villain". And his apprentice Bai Yunyan happens to be a once-in-a-century "congenitally confused villain with a destiny"...
When the world's strongest alliance of righteousness, the darkest demonic forces, and those old monsters hidden in the shadows of history all targeted this little girl who couldn't even tie her shoelaces, Liang Yuan could only bite his cigarette butt and stand up: "Although I am a fool, whoever dares to touch my apprentice, I will let him know what a real villain is!"
