Su Chen transmigrates into the Honkai: Star Rail universe, only to find himself stuck as a lowly waiter on the prestigious Herta Space Station. Lacking any innate powers or noble background, he despairs until a sudden awakening grants him the 'Plane Mobile Game Development System.' His mission is clear: develop and promote the very game that defines his new world, Honkai: Star Rail, to the station's inhabitants.

In exchange for traffic, attention, and likes, he earns points to unlock powerful rewards and gacha opportunities. Su Chen releases the game, shocking the staff and Lead Researcher Asta with its hyper-realistic depiction of their home, including accurate forecasts of Antimatter Legion attacks and appearances by infamous Stellaron Hunters like Kafka. As the entire space station becomes obsessed with the game, Su Chen rises from an invisible servant to the center of galactic attention, using his unique cheat to influence fate and uncover secrets before they happen.
