When Wang Xiaohu saved a stranger’s life, he never imagined it would lead him into the gilded cage of a billionaire’s mansion, posing as a long-lost cousin. Inside, nothing is as it seems. The patriarch, Li Jiangang, is infertile and secretly plots to “borrow” Xiaohu’s vitality to produce an heir, all while scheming with his mistress, Ye Tian’ai, to murder his own wife, Chen Jingjing, and seize her fortune. But Xiaohu is no pawn, Chen Jingjing is not the helpless heiress she appears, and even Ye Tian’ai plays a deeper game. In this mansion of mirrored lies, every smile hides a knife, every alliance is temporary, and the only thing more dangerous than the plot is the truth—because in this family, everyone is ready to kill to get what they want.
