On the isolated "Memory Ark", Lin Mo, the archivist numbered K-734, sorts out the memory backups uploaded by humans day after day. He has no past, only cold data and other people's joys and sorrows. Until a fragmented and abnormally numbered memory file "Resound" arrived, in which the broken images and familiar calls resonated strangely with his blank past. In order to explore the truth, Lin Mo embarked on an illegal journey, only to find that he was not only a bystander in memory, but also the core of a story that had been carefully erased. Is this isolated island a refuge for human civilization or a prison that imprisons him alone?
