The moment the Holy Light Magic Array was disrupted, Amberser teleported into the city and unleashed a massive Dark Art.
The entire Sandshadow City was enveloped in a thick black mist, not just thick enough so you couldn't see your fingers when you waved your hand, even placing your palm in front of your eyes rendered it invisible.
But the magic left by Katherine could only disturb the Magic Array for a few seconds. The Holy Light Magic Array operated once more and immediately locked onto Amberser, an Undead exuding an aura of darkness.
Amberser had always wanted to experience the Laine Empire's Faith Conversion Magic Array firsthand, and now that he did, he found it was indeed formidable.
The converted power of the Holy Light deeply infused within Sandshadow City's Magic Array. Upon Amberser's appearance, the Holy Light formed dozens of light swords and flew toward him.
With that kind of power, the former Amberser definitely wouldn't dare to resist directly.
