Trapped in a apocalyptic book world due to a system error, Xiao Jinsheng discovers she's been cast as the malicious supporting character destined to rival the protagonist—but compensation comes in the form of five devastatingly powerful Beast Husbands: a mysterious snake-man draped in violet locks, a sharp-tongued youth with feline ears, a charismatic black panther radiating primal magnetism, a nurturing sheep-man guardian, and an elegant Dragon Sparrow noble. Recognizing them instantly as her lost husbands, Xiao Jinsheng eagerly activates the system's promise. "11111!" she cries, frantically pressing her fingers against their poster images. The reward seems too perfect—until reality shatters the fantasy. These aren't devoted lovers; they're five executioners bent on her destruction. The snake-man emerges from the black market seeking vengeance. The cat-eared youth demands daily divorces. The black panther threatens her with bloody brutality. The Dragon Sparrow treats her as poison. Even the gentle sheep-man conceals a predator's heart beneath his kindness. Survival depends on a brutal world law: Beast Husbands must follow their wives into death, making her murderous quintet her unwilling protectors. Determined to strengthen her position, Xiao Jinsheng discovers unexpected allies emerging from the shadows. A Demon Lord becomes obsessed with her. The King of the Deep Sea Mermaids surrenders to love at first sight. The Silver Dragon of Cloud Island refuses to leave her doorstep. Watching her grow more powerful and beloved, the five Beast Husbands—once desperate for escape—crumble and kneel, now clinging to her side even unto death itself.
