Monster Hunter, start with a wife

In a world ravaged by the invasion of the Void Realm and overrun by bizarre, monstrous beasts, humanity clings to survival within the colossal walls of the Lighthouse City. While the privileged indulge in decadence within the inner rings, the citizens of the outer city endure endless hardship, and those beyond the walls exist merely as fragile ants. Cheng Zhuo is an ordinary high school graduate struggling to survive in the outer city. His fate seems sealed when he awakens a lowly F-grade Origin Card—until he is unexpectedly approached by Ruan Qinghe, a stunning beauty from the neighboring class, with a life-altering question: "Cheng Zhuo, do you want a wife?" Mistaking her sudden proposal for a cruel prank, he initially walks away. But to his absolute shock, he finds himself standing across from her the very next day in the official marriage registration hall. She is deadly serious about finding a husband, and this impromptu union plunges Cheng Zhuo into a thrilling journey alongside uniquely gifted, formidable heroines, where he will rise from the very bottom to hunt the monsters threatening their world.
