Lin Jingzhe, an ordinary young man who lives in the middle-class area and makes a living by interpreting and repairing old memories, accidentally came into contact with a memory chip from the taboo era - "Obsidian" during a job.
In an instant, the buried truth emerged like a ghost. The founder of the city became a conspirator, and the refuge of mankind turned out to be a carefully designed cage. This spying made him the number one target of the "Data Enforcement Bureau", the city's highest law enforcement agency. The ruthless "scavenger" code-named "K" launched a ruthless hunt for him.
In order to survive, and to solve the mystery surrounding herself, Lin Jingzhe took this dangerous chip and embarked on a desperate road together with the mysterious lower-level messenger Xiao. From the neon-lit mid-level corridor, to the sunless ruins of the subsidence area, to the sky area at the core of power, every step is on the edge of lies and truth.
When the final code is unlocked, how will he choose? Destroy this false utopia, or return the painful truth to everyone?
Memory is both a shackle and a key.
