Redpine Region's northern border, inside the Shadow Swamp, a group of witches and aura users guarded a hundred-foot black tower.
At a glance, the black tower looked like an ordinary magic tower.
However, the black tower didn't just absorb mana from the atmosphere. Instead, after the tower was fully charged with mana, the tower would blast the concentration of mana into the skies, scattering it.
The construct was indubitably a mana disruptor whose sole purpose was to collect and disrupt mana signals.
Among the group of witches, the strongest were Peak-stage Senior Witches and Peak-level Rank 2 Aura Masters, while the weakest were Early-stage Senior Witches and Low-level Rank 2 Aura Masters.
At that moment, the Senior Witches were clamoring about their poor situation. They didn't have a problem with the task; they only had a problem with the location.
The Shadow Swamp was an unclean region, home to creatures of the darkness attribute.
