The night of Lin City is wrapped in the bloody smell of superpowers - Jiang Xun is a desperado hiding in the shadows, a "remnant" of the old case five years ago, carrying the secrets of the night watchman agency; Shen Yan is an investigator who steps on the edge of the rules. In order to track down the serial disappearances, he knocked on the door of the underground intelligence station with half a superpower crystal core.
When the morning glow of the dark city burns through the lead-gray sky, the knot of interests binds two people with different agendas: he wants to clear his name, he wants to uncover the shady story, and the hunting net of the night watchman, the undercurrent of the mutual aid association, and the truth that was buried five years ago are crawling towards them along the neon lights of the city.
Are they allies who use each other, or are they each other's salvation? When the muzzle of the gun was pressed against his back in the dark alley, Jiang Xun heard Shen Yan say in his ear: "Your life is now in my control."
Purpose: redemption
