When freshman Lu Ding stumbles upon a blood-soaked stone at a construction site, he discovers his long-dormant golden finger—the Monster Containment Prison—is finally ready for action. After nearly two decades without a single monster encounter, his patience has evaporated. The 749 Bureau offers him the perfect outlet: hunt, contain, and eliminate supernatural threats using their vast resources. Lu Ding becomes their newest investigator with a brutal reputation—no survivors, no exceptions. Legendary demons and nightmarish creatures materialize across the world, only to fall beneath his relentless assault. Each containment grants him devastating new powers: the Stubborn Stone of Nanshan's unbreakable resilience, the Black Old Lady's mountain-moving strength, the Flying Centipede's sky-soaring speed. The 749 Bureau's philosophy demands containment and confinement, but Lu Ding operates by a different creed—complete and total extermination. As supernatural threats escalate and more monsters emerge from the shadows, the Bureau faces an impossible truth: their newest investigator refuses to follow protocol. With Lu Ding on the case, containment becomes irrelevant. There are only ashes and silence.
