Shen Qingyao, a powerful dual-ability user in the apocalypse, is betrayed and triggers self-destruction, transmigrating into a red-eyed white fox and binding with a life-extension system that requires her to rely on Regent Pei Wangshu to obtain vitality. Afflicted with cold poison and wielding supreme power over the imperial court, Pei Wangshu uniquely treasures her above all else. The empress dowager and the Ye family view her as a weak point to check the powerful official, repeatedly setting traps to harm her. Spending days and nights together, the two develop mutual affection for one another. Shen Qingyao successively unlocks spatial and wood-type abilities, and during a surge of spiritual energy, her fox ears and human form are exposed, completely revealing her identity. Together, they join forces to quell court turmoil, unravel the cold poison and the age-old secrets of Southern Xinjiang, moving from human-fox companionship to a meeting of minds in mutual redemption.
