Chapter 369: Flames of Purification

"Icycle Realm!"

A sound similar to hundreds of tinkling glasses reverberated in the surroundings as William activated this Icycle Realm. This spell was one of the most powerful spells in the Ice Wizard job Class. 

It allowed William to create a zone where Icicles protruded from the ground. However, it didn't stop there. Within this battle zone, hundreds of sharp icicles crisscrossed in the air, attacking those that the red-headed boy deemed to be his enemy.

Simply put, it was a slaughterhouse that was designed to prevent others from entering, while keeping its victims inside as they got cut down with blades made of ice.

William decided to go all out because he was not confident that he could prevent anyone from getting seriously hurt from the swarm of undead that had appeared from the depths of the fortress.
