At this moment, in the Immortal World, within the Human Territory, the Barbaric Elephant Mountain Range.
Above the sky, dark clouds roiled, covering a million kilometers in every direction, as countless Immortal Tribulation Lightning bolts flickered like dragons and snakes dancing in the air, exuding waves of terrifying, destructive aura.
Clearly, someone was undergoing a tribulation here.
A lone figure stood tall in mid-air, bathed in golden tribulation lightning.
Each bolt of golden tribulation lightning was incomparably fearsome, imbued with a destructive power terrifying enough to obliterate a True Immortal.
And that person was none other than Zhou Sui.
He was currently undergoing the Ninth Layer of Mahayana Tribulation Thunder.
However, he had not summoned the Mahayana Thunder Tribulation in the Profound Yellow Realm or the Spirit World, but within the Immortal World.
