Zhu Xiaofen, a little pink pig who inherited the reverse genes of her parents, was passed off as a "peerless fierce beast" to enter a political marriage with the Peacock Demon King. The Demon King, who suffers from severe mysophobia and cares deeply about his face, nearly collapsed upon opening the cage to see a pig, yet for the sake of his pride, he stubbornly insisted that she was the "Heaven-Swallowing Pink Crystal Beast." Unexpectedly, a rebellion suddenly breaks out, and Xiaofen relies on her bizarre appetite and divine beast backbone to protect her husband multiple times, ultimately shattering the enemy in her true bloodline form during a crisis. The Demon King also spares no effort, offering his primeval essence blood to save her. Stripped of demon-god destiny and halos, the mysophobic Demon King becomes a barbecue master, while the cute, dim-witted little pig reigns as the boss lady, writing a contrasting sweet and pampered daily life amidst the warmth of human fireworks.
