Information about the Five Emperor Demon Kings was obtained by Ling Xiao from the sealed Night Demon King's memories.
Although the Seven Great Heavenly Demon Kings that make up the Night Demon King seem incredibly powerful in the Mysterious World, they are not top-tier existences in the Demon Realm.
These Seven Great Heavenly Demon Kings are all governed by the Blue Emperor Demon King among the Five Emperor Demon Kings.
However, this is not important.
What's important is that Ling Xiao, based on the data of the Five Emperor Demon Kings and the Night Demon King's memories, combined with the battle intent of the Ancient Heavenly Demon King, surprisingly comprehended a new way of fighting.
A combat style more suitable for the Heavenly Demon Incarnation!
This is the Sky Demon Purgatory!
As the Sky Demon Purgatory activates, Niu ɡui and Snake God emerge in succession, with countless bizarre phantoms flickering beside Ling Xiao.
