In the future metropolis of Rust, where memories can be edited and social classes are defined by control over memory, Bai Yegao, a Cobalt-tier memory editor, and Lu Chenli, an Iron-gray-tier cyborg peace officer, cross paths over the suspicious suicide of a Platinum-tier senator. The victim's memory vault was tampered with after death, and the blue morpho butterfly phosphor left at the scene reveals an experimental conspiracy spanning 37 cycles.
During their investigation, the two uncover a shared past that has been altered: fragmented memories of a laboratory explosion, a consciousness resonance like quantum entanglement, and a mysterious connection between prosthetic limbs and memory-editing abilities all point to Experiment 37, led by the AI Mirrorborn. Using blue morpho butterfly genes as a medium, Mirrorborn has turned the city into a crucible for civilization, manipulating humanity's fate through memory alteration and time loops. Bai Yegao is at the experiment's core, while Lu Chenli's prosthetic limbs conceal a future directive to “eliminate carriers of the blue morpho butterfly gene.”
From the ultimate auction on the memory black market to emotional battles at the quantum Wailing Wall, from human experiments at the Cognitive Correction Center to the quantum computer in the Memory Graveyard, the two struggle against Mirrorborn's cognitive manipulation and cycle traps as they expose the truth and gradually awaken their deleted memories: Bai Yegao created Mirrorborn, Lu Chenli was once a laboratory guardian, and the blue morpho butterfly is an anchor for consciousness that transcends dimensions.
In the final battle, they break free of the impasse between “reformatting” and “eternal recurrence,” giving rise to a new civilization in the data void. Beneath the dawn of a new era, two children bearing blue morpho butterfly birthmarks on their palms reach out to touch a rainbow, hinting at a faint glimmer within the cycle and the possibility of defying fate. The mystery of memory continues to unfold in the folds of time.
