The young master returns, sweeping away everything.

Chen Fan, the King of Assassins of the Demon-Suppressing Prison, disguises himself as a useless, abandoned young master to return to his family and marry into the Xie family, a wealthy and sickly heiress, to bring good fortune. Xie Wanyue, the eldest daughter of the Xie family, appears to be paralyzed and terminally ill, but is actually a shrewd business genius who feigns illness to protect herself, while waiting for an opportunity to break free from family control, expose internal enemies, and cultivate reliable allies. Chen Fan, step by step, plots his revenge for his mother, reclaims power within the Chen family, and uncovers the long-buried truth of the past. The two join forces, stirring up a bloody storm in the vortex of power struggles within the wealthy family.
