In the rainy and foggy "Fog Shadow City", memories can be extracted, stored and traded. The top memory архивист (Archivist, Archivist) Lin Zhou can repair the most broken memory fragments, but he is unable to piece together the truth about the disappearance of his lover, leaving only a silver pendant that cannot be opened. One day, a mysterious woman named "Xiao" brings a dangerous deal - to completely erase a memory that can subvert the entire city. This commission was like a boulder thrown into stagnant water, dragging Lin Zhou into a huge whirlpool composed of lies, power and forgetfulness. He must make a choice between pursuing his personal past and protecting the city's future, and the sea of memories he has long forgotten is quietly setting off a huge wave that can swallow everything.
