Suddenly, in the distance, a purple light shot up into the sky, illuminating the world afar with unparalleled brightness. Within that light, there was a terrifying power, and even from a great distance, the frightening energy fluctuation could be felt.
Just after the purple light rose, a crimson light also ascended.
Compared to the previous purple light, the energy fluctuation contained within this crimson light was not weak at all.
"That light is from two powerful cultivators casting spells. Besides me, there are other cultivators here.
Moreover, this aura surpasses that of the Golden Immortal Realm, this must be a cultivator beyond the Golden Immortal Realm!"
Cao Zhen quickly flew toward the direction where the sound came from.
In an instant, after traversing the void, he saw two figures appear in his vision.
He immediately restrained his aura and hid in the shadows, observing the two figures.
