Gu Congrong has been sensitive to numbers since birth. It is a gift from the heavens, and she uses it to kill. For years, she has used precise calculations to take lives without a trace. She could have continued living quietly in the abyss, but then she fell in love. Yin Lang's intentions toward her are impure: he came to investigate her. Against his psychological games, she has the greed of a girl starved for affection, and the insecurity of a murderer. When she stands before the court, the world calls her a murderous fiend. Then Yin Lang arrives, and peels back the darkness to reveal the true darkness beneath it.
