In the cyber colony "Ark" surrounding the ice giant, Lu Chen, a low-level excrement handler, accidentally picked up an ancient neural chip from dinosaur excrement. This chip allowed him to deeply synchronize with the mechanical dinosaurs, thus entering the "Dragon Riding Competition" monopolized by the upper class. He rose from the filthiest garbage dump and shocked the audience with his homemade tattered modified dragon. However, he gradually discovered that behind this seemingly glorious competition, there were hidden conspiracy to manipulate the game, taboo human experiments, and a huge lie that shrouded the entire colony - the Jurassic World they were in was just a giant ecological ship drifting in deep space, and human civilization had long been annihilated. When the truth is revealed, Lu Chen must make a choice: stay in the beautiful illusion and survive, or drive the last mechanical dragoon to charge into the dark starry sky.
