Reborn in the Interstellar Era: The Commander's Wife Is Terrifyingly Cunning

After dying in the apocalypse, Su Jiu was transmigrated into a sci-fi interstellar beast-world novel, where she became the overlooked second daughter of a duke’s family. Su Jiu: Wouldn’t it be great to live comfortably without lifting a finger? Why give me such a fragile body after transmigrating? It’s going to cost me a fortune. Just as she was worrying about how to escape her predicament, her reborn older sister, Su Rui, decided she didn’t want the commander she was promised to and insisted on swapping fiancés with her. Su Rui: “I refuse to spend my life looking after a useless man!” Su Jiu thought it over. Gu Lingce was handsome, powerful, and rich. He couldn’t have children and would die young. He was the perfect husband sent by the heavens. She agreed without a second thought. After they married, Su Jiu spent every second hoping to become a widow and inherit all her husband’s property. - Gu Lingce, the empire’s eldest prince and the strongest commander in the stars, was devoted to serving his country and believed himself incapable of love. The marriage had already been arranged, but then the Duke’s family suddenly switched brides. Forced into the marriage, Gu Lingce planned to wait out the one-year cooling-off period before divorcing her. Until one day, Gu Lingce heard his sweet little wife talking in her sleep about waiting to become a widow. He laughed in exasperation. “Even if I die, you’re still mine!” - Su Rui had been doted on by everyone, and no one in her family dared let her suffer the slightest grievance. But in her previous life, she schemed to marry Gu Lingce, only to be completely ignored. She became the laughingstock of the entire empire, while Su Jiu was the female everyone envied, living happily in love with Hanal. Reborn, she would rather die than marry Gu Lingce, so she forcibly took Su Jiu’s wedding match. But married life was unbearable, even harder than in her previous life. One day, Su Rui happened to see Gu Lingce carefully supporting Su Jiu, his face full of affection. Su Jiu looked utterly despairing, the pregnancy test in her hand impossible to miss. Su Rui was so furious she nearly ground her teeth to powder.
