Tianjing City, Ghost King Palace.
As a super-class force of the ancient martial arts world, the Ghost King Palace was undoubtedly one the most powerful existences.
The Ghost King Palace, along with the Sword Pavilion, the Hundred-flower Palace, and the Fiery Emperor Palace, were all super-class forces of Huaxia. Super-class forces all had connections to self-cultivators, including the Ghost King Palace.
First-class martial forces didn't have access to self-cultivators, but super-class forces did. There were even self-cultivators amongst the super-class forces.
There was a self-cultivator living in the Ghost King Palace but the self-cultivator wasn't Ghost King, nor Hell King. The self-cultivator was actually a man named 'Sky Ghost Elder'.
