"Interesting..."
Otto squinted his eyes to look at the protective shield above Stania, which was blocking his Strong Acid, a continuous damage spell.
Now, he could clearly see that the places on Stania's protective shield being smeared by the acid were emitting dazzling light.
This indicated that a large amount of energy conversion was taking place, and it seemed that resisting Otto's Strong Acid Breath wasn't an easy task.
However, before Otto could continue observing, the magic circles of the Magic Cannons under Stania had lit up again densely.
As the brilliance of magic became brighter and brighter, a large amount of magical power was injected into these Magic Cannons from Stania's body, causing the Magic Elements in the surrounding air to gradually become volatile.
Mentor, who was in the Mage's Spire, clenched his teeth, his gaze fixed on Otto's body.
"Paton, increase the magic power injection. I want to see that damned Black Dragon blown to pieces immediately!"
