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 special powers or noble background, he despairs over his insignificant fate until a mysterious voice answers his desperate plea. Awakened with the 'Plane Mobile Game Development System,' Su Chen receives the complete initial version of the Honkai: Star Rail game itself.

His mission is clear: develop and promote this game within the very world it depicts to earn points for powerful rewards. When Su Chen launches the game on his terminal, the hyper-realistic graphics and uncanny prediction of events send shockwaves through the station. Lead Researcher Asta and the staff are stunned as the game mirrors their reality perfectly, even forecasting the imminent arrival of the terrifying Antimatter Legion and the notorious Stellaron Hunter, Kafka.

As chaos brews and the line between game and reality blurs, Su Chen must navigate this dangerous new prominence while leveraging his unique cheat to survive and thrive in a galaxy filled with cosmic horrors.
