The six warships were so easy to spot that Roland could see them from the city wall without ascending to the sky.
Though he trusted Brenda, he was careful enough to fly above a warship with Human Cannonball and cast Evil Detection downward.
Then, redness glittered all over the warship.
He cast Evil Detection on another warship, only to find that it was brimming with redness too.
Hovering in the sky, he found that every warship was so red that they were almost black.
Without any hesitation, he rained fireballs down.
Those fireballs weren't too huge, only about one meter in diameter.
Probably because they never encountered Mages before, those warships weren't prepared for a flying Mage. Though many archers were shooting Roland, most of them missed the target, and the arrows of those who did shoot Roland were deflected by his magic shield.
