In the golden age of the Interstellar Federation, the development of technology allowed human consciousness to be digitized, and memories could be stored, read and even traded. However, when a person dies, his unprocessed consciousness data becomes a dangerous "information ghost", polluting the sea of data.
"Relic organizer" - this special profession walking on the edge of society came into being. They are responsible for sneaking into the fragments of consciousness of the deceased, organizing and formatting these broken memories, and erasing their existence.
Gu Chuan is the most inconspicuous relic organizer in New Feileng Cuixing Port. He deals with the joys and sorrows, love and hatred of the deceased every day. He is low-key and reclusive. He seems to be just an ordinary person who relies on his crafts to make a living. But no one knows that he is the only remaining legend from the golden age of "deep diving" technology - a "conscious submariner" who should have completely disappeared in the "Black Tide Incident" ten years ago.
He wants to bury the past until a mysterious client brings a strange relic - a music box from a Confederate hero. When Gu Chuan sneaked into it, what he encountered was not the glorious memory of a hero, but a deliberately concealed dark abyss that could subvert the entire federation.
Cold killers, powerful giant corporations, the shadow of the Federal Security Service... All forces are taking action upon hearing the news. Gu Chuan's peaceful life was completely broken. He knew he could no longer stay out of it.
When memories can be erased and souls can be encoded, where is the boundary between reality and illusion? This time he not only wants to sort out the belongings of the deceased, but also to find the buried truth in this sea of stars built of lies.
