Nian Yangxiao arrives in a world that shouldn't exist, chasing a ghost of someone he loved and lost. She's alive here, but marked for death by forces that transcend dimensions. If she dies in this reality, she vanishes completely. There's no second chance, no third world where she might survive. Armed with a power to freeze time itself, Nian has to move fast. The killer carries a specific mark, a clue etched into his target's skin. But finding one murderer means navigating criminal syndicates, power struggles, and a city that doesn't know him or trust him. Every gang has their own agenda, and most of them are willing to kill. Time literally stops when Nian needs it to, but the ability comes with limits. Seconds matter. Relationships matter more. Building allies in a hostile world becomes as crucial as combat. Nian fights across impossible odds not for justice or revenge, but for one person. For a love that spans worlds.
