Female chef Ling Xi accidentally connects to the Underworld and opens a small restaurant on the Yellow Springs Road. With human delicacies like saucified fish, hot pot, and glutinous rice chicken, she conquers Underworld bigshots including the King of Hell's adopted daughter, the celestial master Zhong Kui, and Meng Po, turning even the stern King of Hell from "this king does not eat" into a sneak-eating addict and regular return customer. From being ignored to bustling with crowds, Ling Xi establishes her footing with her culinary skills and sparks ambiguous romance with the King of Hell amidst the worldly bustle.
