When whispers at your bedside become a death-knell, falling asleep is like stepping through the gates of hell. Ning Ye only wants to protect his frail younger sister, but he is dragged into a sleep-plague crisis engulfing the entire world. Armed with an old copper coin imbued with uncanny power, he travels through an apocalypse fractured by rule-based horror. The residents of Smiling Town donate happiness every day, while phantoms in the mirror whisper lies about who they are. Yet the Dreamweaver, the savior he seeks, is closely tied to his missing memories and his family’s dark destiny. When the truth comes to light, will he be the one key to ending the apocalypse, or... the culprit who brought it all about?
