Li Xuan, a post-apocalyptic water shifter, accidentally travels to a werewolf world full of mystery and danger. Here, he not only faces his original body's reputation as a lousy gambler and huge debts, but also has to deal with power struggles and territorial rivalries in the werewolf society. In this world, werewolves, humans and Little Brother live together, forming a complex social structure. Li Xuan, as an outsider, must quickly adapt and find his footing. Fortunately, he meets Lin Feng, a werewolf little brother who is cold on the outside but kind on the inside, and his appearance allows Li Xuan to find a touch of warmth in the new world. Lin Feng, as a member of the wolf clan, is discriminated against due to his family's decline and his own special status. He thought he was doomed to a life of loneliness until Li Xuan's appearance broke his fate. Li Xuan not only improves Lin Feng's life with his supernatural powers, but also uses his wisdom and courage to help Lin Feng earn respect among the wolf clan. The relationship between the two deepens through their common challenges, and Li Xuan not only becomes Lin Feng's dependence, but also the favorite husband of his heart. Together, they face the trials of the wolf clan, expose the conspiracy hidden behind the power, and eventually not only win the recognition of the clan, but also build a strong wolf territory together.
