Three days later.
The mysterious power within the Titan Attrition Ring merged into every inch of the unconscious Purgatory Giant King Aibadon's body.
At such close range, aided by the Face of Truth, Green could clearly sense that when the Titan Attrition Ring controlled a World Lord, aside from drawing certain power from vast numbers of illusory creatures, it also drew upon the sovereign's soul.

First, flame enhancement: the base attack degree of Purgatory Fire increased by 100,000 degrees.
Second, strength enhancement: the base attack degree of strength attacks increased by 100,000 degrees.
Third, golden-body infusion: gilded magma infused the true body of Purgatory Fire, repairing damage to the true
