In 2147 AD, when the "data disaster" struck, the global network collapsed instantly. All humans who relied on neural interfaces and intelligent prosthetics were instantly reduced to walking zombies - their consciousness was formatted and their bodies were transformed into "data zombies" controlled by unknown protocols. Civilization collapsed within seventy-two hours, and the steel jungle became a neon hell. Lin Yuan, a low-level prosthetic doctor who was fired from the "Dome Medical Group" due to a medical accident and was heavily in debt, accidentally activated a broken mechanical head while searching for parts in a garbage mountain to repair his old brain-computer interface. Youlan's data torrent broke through the firewall, and an ancient consciousness calling himself "Zero" forcibly bound his damaged neural interface.
