Top neuroethicist Ella Venn was one of the creators of the "Prism" memory technology. An accident caused her to lose key memories, and she also glimpsed the terrifying darkness behind technology - someone is treating human memory as soil, grafting, contaminating, and reshaping personality at will.
She transformed into an underground "purifier", holding an illegally modified neural interface, wandering around the bottom of the giant city "New Canaan" where neon and carrion coexisted, and regained themselves for the "polluters" whose memories had been tampered with.
Until a tragic incident of "a loving mother killing her son" dragged her into a deeper nightmare.
The "killing instructions" accurately implanted in the victim's memory are just the beginning. A terrifying plague called "chain pollution" is spreading quietly through the "Prism" network. The upper-class elites are bizarrely depraved, and the lower-class civilians are inexplicably crazy. All clues point to a mysterious existence codenamed "The Gardener" - he regards the human brain as a nursery, uses memory as a seed, and carefully cultivates the flower of evil called "the collapse of human nature."
What's even more fatal is that Ella discovered that in the depths of her broken memory, there were strange-colored rust spots that had the same origin as the "Polluter".
Is she a hunter, or is she the ultimate product of a "gardener"?
Carrying a "self" that could collapse at any time, Ella was forced to form an alliance with a poisonous and mysterious AI "Ark" that was parasitic in the ruins of the old network, and launched a charge into the urban abyss where glamor and decay intertwined.
Cyber prosthetics? No, what she fights against is the invisible blade that tamperes with your cognition!
Memory is the battlefield, truth is the only weapon.
