The Trials of Leon Chen in the Mystic Valley Chapter 89

Just from the name, you can tell that this demonic sect's techniques are abnormal, and even its location is strange.

Lushui County, Yuzhou, is close to a tributary of the Yellow River. The most famous thing is the large reed swamp beside the river bend outside the town. There have always been legends about ghosts.

At night, the river beach was quiet, not even a human figure.

This is the place where the earth's Yin Qi gathers.

I don’t know which dynasty or generation started, but there have been mass graves near the river bend.
