In this city that never sleeps, crime is no longer merely an act of violence... it has transformed into a work of art.
A series of murders occur with terrifying precision. At every crime scene, not a single trace is left behind, except for one thing the perpetrator always leaves behind:
A pair of bird wings arranged elegantly beside the victim's body, and a single playing card placed face up.
The police call this culprit "The Dealer."
Every card left behind holds a number and meaning, every placement of the wings carries significance. It is as if the victims were not simply killed, but were merely assigned "roles" in a grand game whose rules no one truly understands.
Li Yuan, the captain of the investigation team, finds himself cornered. He is not fighting against an ordinary criminal, but against a brilliant mind playing on an entirely different level.
Then, Shen Yi arrives.
This calm man with sharp eyes seems capable of reading a language invisible to others. Under his touch, the positions of the wings and the meanings of the cards slowly unravel, revealing a path that was once shrouded in total darkness.
The thick wall of mystery begins to crack.
However...
They have forgotten one crucial thing.
That only the creator of the game knows exactly where every card is placed, and where those wings were always meant to fly.
