A series of bizarre events takes place in Cang Village, at the foot of Cang Mountain: ghosts knock on doors in the dead of night, female ghosts wail, and villagers are skinned alive. Even more terrifying, the human skin that was peeled off is delivered from house to house by the very person everyone had identified as the victim, and eaten as boar skin! Who is the culprit, and how can their methods be so bizarre and depraved? Then another villager fails to return home for an entire night. With the situation growing urgent, I set off for the depths of Cang Mountain with forensic pathologist Chen Chuan and Detective Scorpion. But a mysterious force leads us to a pit filled with corpses, where we are attacked by a Li Ghost Officer and forced to enter the Tomb of the Ten Sons of Heaven. Whose tomb is this? Could it really belong to the Ten Sons of Heaven of the Yin Palace? The Road to the Underworld, the Naihe Bridge, the Purely Lured Female Corpses, the Ten Kings of Hell... Along with eerie prophecies and terrifying curses, could this place really be... the underworld? In this ultimate nightmare of endless torment, am I even still alive? An ancient tomb, a shocking conspiracy! The End
