Chapter 637: Voidthunder Essence

"How is it Principal? Feeling better?"

"Indeed. This is so mysterious. Even Vivian's purification ability cannot expel the rampaging Source Energy. And yet, your small amount of Chaotic Energy immediately burned it."

The sly old man sighs in relief and amazement as he stares at the wound on his side that has begun to close up. Just a second earlier, it was swollen and pulsating irregularly as though it was about to burst.

That's how scary the rampaging Source Energy was even to a Rank 4 Transcendent like him.

Although it wouldn't be enough to kill him, he would have to recuperate for a few months or years before it disappeared completely. During those times, he'd feel the wound burn through him as though a scorching hot iron stake was branding him.
