In such a large-scale battlefield, ordinary means were completely ineffective. Even if he himself entered the fray, it would not have made much of a difference.
But Du You was different; he had been hiding a very powerful magic. Without hesitation, his figure flashed, and he charged directly into the airborne front line. He glanced around and raised his finger.
Following the motion of Du You's hand, a spell shot out and numerous magic arrays formed in the sky, totaling 330 upon a careful count. At the center of each magic array, a black fireball began to coalesce.
The vast array that filled the sky sent a chill through everyone below. Not only was the range enormous, covering the entire battlefield, but the threat emanated from the fireballs let everyone know this was no joke.
