Nine Nether Underworld.
A massive mansion deep underground, covering more than ten thousand hectares. The buildings within the mansion are grand and luxurious, but due to its location beneath the Nine Netherworld, it is perpetually shrouded in chilly winds and darkness, never seeing the light of day.
The mansion must be lit with lamps daily. Under the eaves of each building hang ghost lamps, resembling will-o'-the-wisps, emitting a purplish, eerie glow, quite terrifying.
Inside a grand hall of the Netherworld, Lvo Zhenyu knelt on the ground, a Yin God stood before him, one of the famous Yin Gods of the Nine Netherworld, named Zhuu Jiuyin.
Legend has it that Zhuu Jiuyin was once a Divine Beast, with a human face and snake body, holding a pearl in its mouth, incredibly powerful. Later, due to violating the Heaven and Earth Laws, it was cast into the Nine Nether Underworld, becoming a Yin God, thoroughly falling into a realm of evil, a deep abyss of sin, never to return.
