The ground was filled with countless strange-looking human-faced plants. The ferocious faces of the human-faced plants kept spewing out black fogs, even forming dark clouds in the sky.

There were all kinds of strange ghosts and gods flying in the sky.

It had a human face and a bird body, a beast head and a human body, an evil spirit, a Yaksha, and a ten-headed snake.

The sight of blood and the screams of ghosts and gods were alluring.
