Xu Lingqu, a former order enforcer in the post-apocalyptic era, transmigrates into the body of a frail orphan girl with the same name in the interstellar age. Commander Xu Chengbi adopts her and sends her to Moye Star Academy. Hiding her SS-level mental power, she astonishes everyone with her post-apocalyptic life-or-death combat skills and command tactics. She repeatedly overcomes challenges in physical training, shooting, and underground labyrinth trials, wins over a group of companions, and uncovers long-buried secrets about the Galactic Pioneers and her personal mecha, Lumiere. With her exceptional talent for coordination and strategy, she becomes a one-of-a-kind, all-around commander at the interstellar academy.
