In a world where reality and dreams erode each other, the cloud-herding man Amu lives a lonely life in the sky. Until he found a mysterious key in Yun Kun's body and triggered the guidance of the "Dream Weaver's Core", an artifact left behind by his mentor - he must return this item to prevent the catastrophe of "the sky peeling off". To this end, he had to go deep into the "Ocean of Common Dreams" with chaotic laws shared by all human consciousness, and fight against the "Dream Weaver Society" who tried to cover up the truth and sacrificed the peripheral world to maintain the eternal dream in the core area. As the journey deepens, a chilling truth gradually emerges: the world he knows is itself an ancient dream that is collapsing. The core in his hand is actually the final key to restart or end this dream.
