In the vertical city "Dome", memory is a commodity that can be extracted, traded and tampered with. The oppression at the bottom and the luxury at the top are maintained by a layer of technology giants called "Yongyi Group".
Lin Xun, an amnesiac who makes a living by repairing other people's broken memories, his world completely collapsed when a mysterious "memory crystal" arrived. This memory crystal is not only the only key to his blank past, but also the talisman that leads to death.
In order to survive and find "himself", he was forced to join forces with "Nightingale", the most dangerous female hacker in Xiacheng District, and embarked on a desperate journey. From the neon-lit criminal streets to the heavily guarded summit of power, every step is on the edge of memory.
When the cocoon of truth was peeled back layer by layer, Lin Xun found that he was not only the prey of this conspiracy, but also the center of the storm. His former identity was enough to overturn the entire world.
Can memory define a person? When the past is an abyss, will he choose to sink or make a new choice on top of the ruins? This is a story about search, betrayal and resistance.
