Do It

At this moment, right in front of the Phoenix's chest, a red fireball appeared, small but seemingly very dense, churning endlessly like a balloon about to burst.

As Oliver continued to observe, he found the fireball expanding at an unimaginable speed, making him retreat in haste.

The size of the fireball was truly unimaginable.

Even when Oliver retreated to a distance of 15 kilometers, the fireball was still in front of him.

Quickly, he looked down only to find that it had already almost reached land.

The sea beside the wall was boiling dry, leaving dead fish to burn.

Oliver wasn't sure how the bird could have released such a large flame.

He didn't think he could do it.

"Lady Phoenix, is this really a Class S Skill?" Oliver asked.

"Yes, the domain is indeed like this. Even Class S, the resulting Zone is huge."

"What about SSS+ Class?"
