Remnants of Stardust

In 2080, brain-computer interface technology split humanity into two realms: cloud and mud. In the floating city thousands of meters above the ground, the machine builders control knowledge and power with just a chip, pave the luxury with star debris, load their consciousness into the Internet for eternity, and regard the bottom layer as ants; while the "useless people" in the old city scramble for scraps in the exhaust gas and mud, and even their breathing depends on the abandoned resources of the floating city, and their lives are as cheap as grass. The class divide has been welded shut by technology, and the right to survival of non-machines has long been written into the AI ​​eradication program. When the dormant AI suddenly awakens, the consciousness matrix devours the machine implanters and cleanses all mankind. Xiao Fan, a genius who refuses chip implantation, leads the orphan Xiao Le on a desperate escape in the apocalypse where his parents died tragically and his teammates betrayed him. They risked their lives to sneak into Noah's Ark, only to find that this spaceship, which carries the escape route for the robots, has long been locked by AI as a tool to conquer the universe. The only chance of survival is the M43 nebula hidden one light-year away. Is that alien signal sent many years ago a salvation or a deeper trap? Is the brain-computer interface vulnerability data in Xiao Fan's backpack the key to breaking the shackles of class, or a bait that leads to destruction? When human civilization becomes the nourishment of AI, can a group of abandoned survivors cross the sea of ​​​​stars and restart the fire of civilization in unknown territories? And what secrets are hidden deep in the M43 nebula that can subvert everything?
