The sky is dark, the earth is dark, and humans and ghosts are on the same path.

Gu Xu, with three talents, traveled to a world of cultivation where demons were rampant, and became an ordinary clerk in the Exorcist Department of the Great Qi Dynasty.

He just wanted to practice quietly and seek immortality.

However, he accidentally turned the world upside down.

Shrouded in gray fog, the world is immersed in darkness.

You hear low roars and gnawing sounds;

you smell the strong smell of blood and decay;

you touch the wet and slippery limbs;

don't panic, they are the "relatives" accompanying you.

Born in the darkness, cut off everything with a bright and sharp blade!

This is a story that makes the existence wandering in the darkness flee madly to the place they call "light".
