After being hit by a mysterious note on the subway, Lin Yuan actually traveled through the unfinished Cthulhu apocalyptic novel "Whispers of the Abyss". Giant scarlet eyes hung in the sky, the streets were crawling with twisted flesh, and strange bloody words kept appearing in the notes in his hand: "Don't believe anything, including me." When he thought he had found the altar to break the doomsday, he discovered that he was just a "narrative patch" used by the author to fill in the plot holes, and every death would restart a more terrifying cycle. Countless "selves" in parallel time and space meet here and are trapped in an endless narrative corridor. Under the gaze of the abyss, can they tear apart this "novel" that traps everyone and find the real exit?
