A bizarre case brings Chen Mo, a disgraced detective, face to face with Su Jiu, a living corpse who has been imprisoned for a hundred years.
One is rational and resilient, the other walks the line between good and evil. One longs to return to the light, while the other seeks to settle an old score.
On the very first day they are forced to work together, Su Jiu tells him, "You and I are both pieces on someone else's chessboard."
He refuses to believe it, until the curses come true one after another, and the two of them are forcibly bound together by a "Symbiotic Curse."
If he lives, she can live. If he dies, she will vanish too.
In a city crawling with followers of evil gods and mysterious entities, the only way for this abnormal duo to survive
is to walk the razor's edge between betrayal and trust, and uncover a bloody truth that has endured for a hundred years.
"Chen Mo, if breaking the curse means you have to die, what will you choose?"
"Then we'll live on together, until we dig out that eye behind the scenes... with our own hands."
