The story begins when trainee reporter Lin Xia investigates the serial disappearances in Qinglan Town, but uncovers a shocking conspiracy spanning three centuries - this seemingly ordinary town is actually a living petri dish of the "Seventh Laboratory", and the townspeople are all genetic containers for the immortality project.
When Lin Xia discovered a clone specimen with her birthmark engraved on it in an abandoned clinic, when she witnessed police officer Chen Mo being transformed into a half-human, half-animal killing weapon, and when the time-space anchor she personally detonated spawned countless versions of herself in parallel worlds, she was shocked to realize that she was not the pursuer, but the most primitive "matrix" of the entire experiment. From the first-generation cloning capsule in 1977 to the consciousness matrix in 2123, every choice is strengthening the Ouroboros-like death cycle: the blood stains on the clinic operating table come from the gunshot wound of the future self, the postmark date of the anonymous reporting letter is later than the time of receipt, and the "murderer" convicted on the trial bench is exactly her twenty years later.
In this self-war that spans time and space, Lin Xia must join forces with the afterimages of different timelines: the reporter who exposed the black market transaction in 1998, the scientist who destroyed the data in 2015, the fugitive who was charged with the crime in 2035... Every decision is splitting a new Möbius strip. When the consciousness of the immortal madman Lu Wenyuan takes over the biological empire of the world, and when Qinglan Town turns into an altar of flesh and blood devouring memories, the only key that can end the closed loop is the ever-collapsing ∞-shaped crystal in Lin Xia's right eye - it is her mark as the first-generation experimental subject, and it is also the seam of all space-time rifts.
