The vast undersea mountain range, riddled with ravines, saw one majestic and noble cave mansion after another, perched on mountain peaks, mid-slopes, and flat lands alike. At a glance, tens of thousands of these cave mansions had been constructed, with demon cultivators coming and going in groups.
Compared to the Red Blood Territory, this place was flourishing beyond measure.
In the center of this grand undersea mountain range stood the towering Nine Evil Hall, which dominated all other structures in height and occupied a staggeringly large area.
The overall layout of the Nine Evil Hall was in the shape of the "Twelve Capital Gates," featuring twelve palaces at the positions of the formation's eyes. Between these palaces were gardens, private courtyards, pavilions, and more. The number of guards at the Nine Evil Hall was an astonishing tens of thousands.
It could be said that the population inside the Nine Evil Hall alone could match that of the entire Red Blood Territory.
