Xiao Yi glanced at the barrier a hundred meters away.
These individual barriers were intricately arranged into a formation.
It was none other than the Ten Realms Annihilation Formation.
Xiao Yi and the Black Robed Elder were now within this formation.
The Black Robed Elder was an elder from the Black Demon Hall.
As for the Black Demon Hall, it was a force that emerged from nowhere.
Mysterious and powerful.
Even the Demon Hunting Hall had scant knowledge about them.
All that was known was that they caused trouble everywhere, committing wanton slaughter.
This caused both the Demon Hunting Hall and the official forces of Northern Mountain County immense headaches.
The Black Robed Elder was the only member of the Black Demon Hall listed in the Demon Hunting Hall's archives.
Xiao Yi had only seen his wanted portrait and a description of his strength; he knew nothing else.
