After Chen Lillian self-detonated her crystal core in the apocalypse, she unexpectedly found herself in an interstellar era, occupying the body of a girl who had just lost an arm. On the day she was discharged from the hospital, Chen Lillian learned she was to enter an arranged marriage. Her intended spouse was also disabled—she lacked an arm, while he was missing both legs. It seemed like a perfect match. Upon discovering that marrying him would grant her a mining planet, Chen Lillian decided without hesitation: she would marry! Yuan Vincent had once been an S-class Sentinel prodigy. During a real combat mission, he lost both legs. From then on, this once-gifted genius was labeled a failure, abandoned by his family and mocked by former rivals. Even those who once admired him kicked him while he was down. As his rank continued to drop, Yuan Vincent gradually sank into despair. Everything changed when a one-armed girl entered his life. Her optimism and unwavering spirit quietly lifted him up, encouraging him and renewing his hope. She planted a “crystal core” within his barren wasteland. From there, he soared to unimaginable heights, ultimately becoming the strongest force in the interstellar realm.
