In 2105 AD, Su Qiyuan, a civilized archivist, accidentally activated a quantum memory chip engraved with "Star Bridge" while sorting out family relics, tracing back to the starting point of the Su family's rise in 2025. Through the memory fragments of four generations, he witnessed his grandfather Su Zhenbang founded Xingqiao Technology with the benevolence of a doctor, but fell into the whirlpool of capital and ethics; his uncle Su Mingzhe broke through the red line of digitization of consciousness in pursuit of profit, triggering a social crisis; the family was divided and fell in the technological boom, and ultimately became a tragic footnote in the transformation period of carbon-based civilization. Su Qiyuan examines the past with the eyes of the future. In the tearing of historical data and emotions, he asks about the boundary between technology and human nature - when civilization rushes to the stars, who still remembers those night watchmen who were crushed under the wheels?
