Beyond the realm of the living, where mortals dwell, lies the so-called Netherworld inhabited by spirits. For centuries, tales of ghosts, spirits, and vengeful souls have circulated widely among humans, alongside legends of the Underworld's gloomy abyss.

Does it truly hold beings like the legendary Black and White Impermanence, Ox-headed and Horse-faced Demons, the King of Hell and his minions, along with the terrifying Eighteen Levels of Hell...? Now, let us journey through this so-called Netherworld alongside our protagonist, Li Feng, and lift its veil of mystery!
