His name is Lu Yuan, codename “Night Judge,” the most outstanding A-rank adjudicator in the underground organization known as the Tribunal.
Ten years on the job, a 100 percent mission success rate, and not a single mistake. His work: judging the wicked beyond the reach of the law. His principle: kill only those who deserve it, and never kill indiscriminately.
He is the executioner of the night, having turned himself into a blade.
Until he meets Su Wantang.
Deputy chief of the Serious Crimes Squad: sharp, tough, twirling a pen during interrogations and sipping iced Americano. She can't tolerate the slightest wrongdoing. She has been after him for three months, not to pursue him romantically, but to pursue the case. She investigates everyone he kills and follows up on every clue he leaves behind.
A game of cat and mouse, with both sides refusing to yield.
But the truth is far more complicated than a chase.
When Lu Yuan discovers that the memories he lost twelve years ago point to a human experimentation project called “Project Rebirth”; when he learns that “the Scales,” the Tribunal's supreme leader, is inextricably linked to the project; when he realizes that the boy beside him, codenamed “Zero,” is actually another version of himself...
He begins to wonder whether the blade in his hand is a weapon for judging the wicked, or a pawn controlled by someone else.
And when the truth emerges about Su Wantang's father, Su Yuanshan, a police officer who died in the line of duty while investigating Project Rebirth, they discover that their fates were intertwined twenty years ago.
That year, she was five and he was seven. In the darkness, she offered him a mint.
Twenty years later, he avenged her father, at the cost of ten years behind bars.
