“This is the territory of the Ghost Clan.”

Gui Qi stopped in his tracks. “The Ghost Clan’s buildings are all attached to the cliffs of the abyss, and from the outside they look like inverted cities.”

At the very bottom lies an underground river, flowing with the waters of the Yin Spirit Spring. The cave at the very top is the dwelling of the clan elders. I will take you to find the Old Man of the Underworld.”

Gui Qi led the group up a spiral stone staircase.

The stone steps are narrow and steep, with a hard rock wall on one side and a bottomless abyss on the other.

At the entrances of several caves along the way, ghost cultivators poked their heads out to scrutinize Chen Ping and his companions, their eyes filled with scrutiny and curiosity, but without hostility.

After walking for about fifteen minutes, they arrived at a relatively open cave.
