Yun Yi, heir to the Great Xia financial conglomerate, is assigned a special mission by national security. He infiltrates the City of Sin, Goethe, by swapping souls, with the goal of capturing Professor Yao, a defector.
When he wakes up, he discovers that he's become a frail young heiress, abused by her stepmother and forced into marriage by her father.
Faced with a table full of meat and a bowl of slop for himself, Yun Yi flips the table.
He slaps his scheming stepsister across the room, knocks out his spoiled stepsister's brother with a punch, and breaks the housekeeper's arm with a club.
“From today on, I'm in charge of the Liu family.”
His stepmother hires a butcher to tie him up? He uses Great Xia's business model to crush the competition, sweeping the city with food delivery and fashion brands.
The city lord wants to sacrifice the lives of everyone in the city to become a god? Yun Yi pulls out a Twin Fish Jade Pendant and sends him straight to hell.
When the truth comes to light, everyone is stunned: inside this body named “Liu Ruyan” lives a man more terrifying than a demon.
