Yun Shu, whose gender was impossible to discern, was treated as a pawn by his family and forced to take another's place in marriage to Ye Sha, the famously violent Demon Lord of the Nine Netherworlds. He tread carefully, keeping his intersex body and divine bloodline a secret. Little did he know that Ye Sha had seen through everything the moment he lifted the bridal veil. From a marriage of convenience built on mutual suspicion to standing together through life and death, their bond began with a lie. Yet when divine pursuers and family conspiracies came one after another, that marriage became their only tie as they defied fate and fought side by side.
