Legend has it that the Ghost City is hidden in a large tomb. Some people have seen the Ghost City, but they all died.
At night when the Ghost City appears, the night sky is strange, half white and half black.
There will be a lavender mist surrounding the ghost city, and there may be only one person who can enter and leave the ghost city - Niyan, the ghost name of Si.
He has a bad appearance and a eccentric nature, and he is also a misty person in the ghost city.
No one knows her origin, and no ghost can see through those eyes that glow blue at night. No one knew that she was the child of the Ghost King's concubine, and she was actually about the same age as the Ghost King.
With such a bad face, all that is left is a smile that makes people unable to see through...
