In Liulic City, where technology can access and delete memories like files, the top "memory fabricator" Lin Mo makes a living by sneaking into other people's consciousness and retrieving lost memories. He is calm and professional, but he has never been able to fill in the blank space in his heart about his family. One day, a mysterious woman named Eve brought a difficult commission: to retrieve a core memory that had been artificially "formatted." When Lin Mo sneaked into the island of memory shrouded in fog, he discovered that this was not a simple forgetfulness, but a carefully guarded secret. This secret is not only related to Eve's life and death, but also inextricably linked to the darkest power in Liuli City and his own lost past.
