[Science fiction + system + multiple split personalities + cyberpunk]
When memory becomes a weapon, the soul is just a puzzle piece of pieces.
In 2088, the interstellar port "Neon City" is ruled by a memory monopoly group. Part of human memory is a tradable commodity, and the side effect is split personality. Under the threat of death, Xiao Chen accidentally activated the memory fragment collection system - plundering other people's memory fragments, integrating combat experience, knowledge and skills, and even awakening the afterimage of the deceased's personality.
