Welcome to the bustling and hilarious underworld world! Black and White Impermanence are ordered to roam between the yin and yang realms, Ox-Head and Horse-Face often cause comical blunders, Meng Po guards the Naihe Bridge brewing soup, and a crowd of underworld colleagues stage hilarious daily routines.

The majestic underworld sheds its serious shell, filled everywhere with twists and joy. Breaking the gloomy impression of the traditional underworld, watch a group of underworld emissaries diligently handle cases while staging various ridiculous iconic scenes.
