Chapter 600 Time Corridor, Re-Stamping the Mark_3

"Someone actually came in," Grayson's eyes showed a trace of excitement, followed by surprise and uncertainty. When had the Purgatory Demon God become so trustworthy?

Or was it someone from another race, or perhaps... a human strong man.

Under Grayson's solemn and astonished gaze, the rumbling noise grew louder and louder, even causing the entire Great Hall to tremble, as if a gigantic creature was rapidly approaching.

Boom! High tens of kilometers, the right side corridor of the Great Hall, supported by huge stone pillars, collapsed, and a black-haired young man with loose hair slowly emerged from the violent smoke and dust.

Terrifying golden-white lightning leaped around his body, emitting a Destructive Aura that even made Grayson's heart tremble.

"Darren Callum!"

Upon seeing the newcomer's appearance, Grayson's face instantly showed horror and disbelief because, at that moment, Jack Clark was emitting a Supreme Level of Rule Aura.
