When Guan Shan received a horror game simulator implanted in his consciousness, reality transformed into a nightmare. Gruesome meat restaurants with corpses displayed in their kitchens, desolate apartment complexes echoing midnight phone calls, psychiatric institutions harboring dangerous criminals—all became his twisted playground. [Defeating the ultimate BOSS is the sole path to escape this hellish simulation.] As a typical person, Guan Shan faced overwhelming terror. Confronted by monstrously powerful Bosses, his only strategy involved slaying creatures and collecting equipment for survival. Each simulation pushed him to his breaking point, barely clinging to existence. Yet paradoxically, to everyone else, Guan Shan himself appeared as a terrifying anomaly. "Captain, he annihilated the S-class dangerous psychic and destroyed the entire facility. Why does he look so desperately frightened? Should we intervene or evacuate?" "Are you insane? He's advancing toward us! Retreat immediately!"
