"Interesting." Troyer Des looked interested in the enemy's provocation. His body glowed when he summoned magical energy. 

"Take this! Hah!"

Troyer Des summoned Wind Blades and fired at the enemy. He was an experienced spellcaster, therefore his aim and power with the long-range magic attacks were pretty good.

"Dammit! He was indeed strong," Troyer Des muttered with knitted brows.

Even an attack from a gold-rank Guardian failed to touch the enemy?

Seeing that, Rossbert said, "Let's get out of here first—", he hastily decided, but the enemy would not allow them to do that. He interjected saying, "No, you can't leave here without my permission. Come forth!"
