An old palace that is about to collapse, and a group of people who are out of place.
The once glorious Night Watch Division now has only a handful of people left, struggling to survive in the treacherous world. When An Minghui, a girl from the ghost market, bursts in with a special skill from the underground, she becomes a beam of light shining into this stagnant water.
Here, there is only a thin line between genius and madness, and protection and destruction are mutually exclusive. In the whirlpool of mystery and intrigue, before dawn at the end of the long night, they will fight to clear the wronged and find a way out for themselves.
Purpose: Guard the glimmer of light in the dark night and seek justice outside the rules. Through the confrontation between the Vigil Department and the Qing Ping Department, the work explores what real justice is - a "Qing Ping" that adheres to procedures, or a "Vigil" at any cost? A group of forgotten little people, using their own paranoia, tenderness and sacrifice, hold up a sky for the powerless in the cracks of decayed rules. This is not only a case investigation, but also a torture of the world: when the light no longer exists, the night watchman ignites himself and becomes the light that pierces the long night.
