This sudden and overwhelming aura was sensed by everyone present, prompting them all to look up towards the sky above the Ancient Arena, uncertain about what kind of change had occurred.
Many of them were not participating in Tianyuan City's talent competition for the first time and were very familiar with this aura, understanding that it only appears when the Tianyuan Secret Realm is about to open.
However, what surprised them was that the opening of the Tianyuan Secret Realm usually required several Divine Power Realm powerhouses to jointly activate the array patterns on the Ancient Arena, and this was the first time it showed signs of self-activation.
"Is the Tianyuan Secret Realm about to self-activate? What on earth is happening?"
Not only Lei Bikuan was surprised, but even the representatives of various major powers were also astonished.
They were just as familiar with this aura, recognizing it instantly as the aura of the Tianyuan Secret Realm from the moment it appeared.
