In the "New Chang'an" city of the future, which is highly mechanized and where information flows like a waterfall, the boundaries between humans and androids are increasingly blurred. The protagonist of the story, Zero, is a "cyborg" (a human with a large number of mechanical modifications) who possesses ancient martial arts skills, but is troubled by a mysterious memory fragment. He was once the top "scavenger" in New Chang'an City, specializing in dealing with those "data ghosts" and "mechanical rebels" who wandered on the edge of the law. However, during a mission, he accidentally discovered that he had been implanted with a certain program, and this program seemed to be closely related to the secret plan of the "Tianshu System", the highest authority in New Chang'an City. Zero begins to question his identity. Are his "memories" real or programmed illusions? In the process of pursuing the truth, he was involved in a huge conspiracy involving human free will and the absolute dominance of AI. He must make a choice between the cold mechanical logic and the "martial spirit" gradually awakening in his heart, and ultimately determine the future of New Chang'an City and even human civilization.
