**When truth is swallowed by darkness, someone will always carry a light forward.**
**Zheng Mingliang, a criminal investigation team captain haunted by the mystery of his father's disappearance, stumbles upon clues to a cold case sealed away for twenty years while investigating a bizarre murder.**
Lin Yaodong, a rising star in finance, is found dead in his own mansion. His body has been carefully arranged in the center of the living room, his expression peaceful, as if asleep. There are no signs of a struggle or a fight, only a missing wedding ring, a copy of "The Art of Death" deliberately opened to a particular page, and a mysterious scrap of paper still undigested in the victim's stomach.
**Behind the case lies a criminal organization codenamed Wan, and Zheng Mingliang discovers that it is connected to his father's disappearance twenty years ago.**
**As his investigation deepens, he gradually uncovers a vast criminal network spanning the business world, politics, and the underworld.**
- **Why was the elegant, mysterious widow Su Yuan missing a diamond earring on the night of the murder?**
- **What exactly did financial magnate Zhou Mingyuan discuss with the victim in their final phone call?**
- **What truth will the key to his father's safe lead him to?**
**Danger closes in from every side.**
- The evidence room is broken into in the dead of night, and crucial evidence vanishes.
- An anonymous text warns him: “Stop investigating, unless you want to follow in your father's footsteps.”
- His apartment is ransacked. Beside an old photograph of his father, the victim's missing wedding ring has been placed in plain sight...
**This is a deadly game of wits spanning twenty years.**
