His name is Lu Yuan, codenamed "Night Trial", and he is the most outstanding A-level judge in the underground organization "Judgment Office".
After ten years in the industry, the task completion rate is 100%, with zero mistakes. His job - to judge the wicked beyond the reach of the law. His principle - only kill those who deserve to be killed, never indiscriminately.
He is the sword bearer at night, and he lives his life as a sword.
Until he met Su Wantang.
The deputy captain of the serious crime team is sassy and tough. He turns to the interrogation and drinks ice-cold American food. There is no sand in his eyes. She had been chasing him for three months—not a person, but a case. She wanted to investigate every person he killed. She had to break every clue he left.
Cat and mouse game, tit for tat.
But the truth is more complicated than a chase.
When Lu Yuan discovered that the memory he lost twelve years ago pointed to a human experiment project called "Rebirth Project"; when he discovered that the Supreme Leader of the Judgment Institute, "Libra", was inextricably linked to this project; when he discovered that the boy code-named "Zero" next to him - turned out to be another one of himself...
He began to wonder whether the knife in his hand was a weapon to judge evildoers or a chess piece manipulated by others.
And when the truth about Su Wantang's father, Su Yuanshan, a police officer who died in the line of duty while pursuing the Xinsheng Project, emerged, they discovered that the fate of the two had been intertwined twenty years ago.
She was five years old and he was seven. She handed him a mint in the dark.
Twenty years later, he sought justice for her father, at the cost of ten years behind bars.
