In the future city "Xinhai" where memories can be extracted and traded, Lingzhou, the top memory ferryman, is like a lonely boat with no direction, transporting the most private memories to customers, but only forgetting his own past. A mysterious commission drew him into the center of the whirlpool: a woman codenamed "Night Owl" asked him to steal a core memory that was encrypted in layers. The moment he dived into this memory, Ling Zhou was shocked by the burning emotions and broken images. This is not only a mission, but also a cruel pursuit of self. When the island of memory emerges in the sea of oblivion, what he will face is the truth that can overturn the entire world, as well as his own buried identity.
