Cangwu Mountain Celestial Master Mansion's only female disciple, Jiang Xiaoxiao, burdened with a curse of turning three inches tall on the night of the full moon, drags a kitchen knife down the mountain to find her husband. At a glance, she locks onto Xie Xun, the deposed prince stripped of his dragon Qi and sealed in the countryside. "I am here to be your wife!" Armed with her kitchen knife to slay evil spirits and drawing talismans barehanded, Jiang Xiaoxiao violently sweeps through the Yin-Yang Bureau. The deposed prince hides imperial bones, plotting step by step to reclaim his dragon Qi. When the air-headed, direct celestial master collides with the scheming, down-and-out prince, capturing ghosts and seeking revenge go hand in hand—the heavens of this Yan State are due for a change!
