Grandma's story is all true.
White mountains and black waters, twilight hides evil, there is an iron rule passed down from ancient times: "Don't go out after dark, be careful to trap your soul!"
My family has passed down the art of soul-binding from generation to generation. The soul-binding book in the left hand and the soul-suppressing ruler in the right hand can travel between the yin and yang realms and extradite lonely souls and resentful ghosts.
People in the village only heard about the presence of immortals in the mountains, but they didn't know that there were countless ghosts who died unjustly lurking deep in the dense forest.
The dead souls whining in the middle of the night, the wild fairies blocking the way and asking for closure, the evil spirits imprisoned by obsession...
One murderous case after another comes to light, humans, immortals, and Yin spirits are entangled endlessly, and the balance of Yin and Yang is at stake.
As night falls, yin and yang interact. If you are walking alone in the wilderness and hear someone calling from behind, remember not to answer.
Otherwise, the next name will fall on my soul book and I will never be able to escape.
