A phenomenon-level hit murder-mystery game has arrived in Jiangcheng, boasting a jaw-dropping gimmick: "Sleep once, take away one of your character's skills." Editor Chen Fang climbs into a gaming pod, hoping to ride the wave of hype, and draws the "Nameless Killer" card. In his dreams, he kills with practiced ease, taking lives in a single blow. When he wakes, a homicide report describes a victim just like the one in his dream. Security footage shows his own face, yet the timestamp says he was napping at the gaming lounge. With just 24 hours, he is forced to master the "killing skills" loaded into his dreams. While evading the police, he searches for other "players" trapped in the same scenario. Every time he closes his eyes, the NPCs evolve, and real-life murders keep escalating. Gradually, Chen Fang realizes that the real thing spiraling out of control isn't the scenario, but the dark self split off from his own consciousness. Before the countdown hits zero, he must kill "NPC Chen Fang" in the hundredth loop, or his real body will be replaced and the city will gain another "nameless killer" who can never be found. A high-concept premise, a relentless manhunt, and a battle of personalities: this urban nightmare is about guilt and punishment. Turn to the first page, and you'll become the next "character" to be hunted.
