The Hell Soul Cannon was a magical bomb released after condensing and compressing death aura.
The power unleashed by this magical bomb was immense. It could even destroy more than half of Aisladu.
Katelyle had not expected Gellert Grindelwald to possess such a technique. This was already on par with Forbidden Curse-level magic.
Katelyle raised his wand and intoned, "O Light Sprites who roam heaven and earth, shine with sacred radiance, tear through the darkness, and destroy evil-Holy Light Demon-Slaying Bullet!"
One spell radiated holy light, while the other released death aura. The instant they collided, it was like a struggle between night and day.
At this moment, it was also a contest of magical power between the two.
Gellert Grindelwald was confident that his magical power was no weaker than Katelyle's. He possessed the Goblin Necklace, which greatly amplified his magic. In addition, the Moss Wand greatly increased the destructive power of his spells, while the Elven Crown allowed him to clearly sense the death aura between heaven and earth and gather it to himself.
That was why the world behind Gellert Grindelwald seemed shrouded in darkness: he was continuously drawing in death aura from farther afield.
Roy Sophie and the other dwarves emerged from the smithy one after another. Bathed in holy light, they felt its warmth and were filled with curiosity about the distant battle.
Roy Sophie left the smithy and ran toward the city wall, eager to learn the outcome.
Glais, Nost, and the other goblins stood aboard the Elf Ark, watching the scene before them, utterly speechless.
Harry and the others were shocked, but deep down, they firmly believed that no matter how powerful Gellert Grindelwald was, he was no match for Katelyle.
William Thomas hid inside the Crystal Ball, not daring to show himself.
