Three Years Undercover, and My Sister-in-Law Wants Me to Rule the Underworld

Chu Xuan is reborn on the first day of his undercover assignment in a crime syndicate.

When he opens his eyes, he finds himself in bed with the beautiful but ruthless fiancée of the underworld’s “young master”!

And it gets worse: the real young master has just been poisoned to death by the woman before him, and killers are about to break down the door. A deadly trap has sprung!

At the brink of life and death, Chu Xuan awakens the [Underworld Godfather System] and turns the tables!

He grabs his sister-in-law by the throat, perfectly imitating the young master’s voice. “Cover for me, and I’ll help you take over the whole organization. Expose me, and we all die together!”

From then on, the underworld gains a ruthless kingpin who preys on other criminals.

His superior roars, “I told you to gather evidence against the rival gangs. You scattered their ashes instead?!”

His sister-in-law trembles. “At first, I only wanted to use him. How did he really become the Emperor of the Night?”

Three years later, when the police prepare to round up criminals across the country, they discover to their horror… that the underground godfather who rules both the legal and criminal worlds and makes tycoons around the globe tremble and bow is the very undercover cop they sent in!
