The difference between a True Immortal and a Human Immortal was almost insurmountable.
Let alone Ao Longyu.
Even Jiang Lan, who possessed the Power Of Nine Tribulations, found it difficult to surmount this gap.
The body of a Human Immortal was still that of a human, while the body of a True Immortal was that of an Immortal.
The disparity was so great that one's immortal force was insufficient to make up for it.
The body of a True Immortal could be degraded to that of a mortal. But the attacks that land would only cause superficial wounds and not harm the foundation.
It was just like how Jiang Lan could still be injured by Ao Longyu despite possessing a golden body.
He was just intentionally suppressing the effects of his golden body.
However, no matter how badly he was injured, they would just be superficial wounds. His foundations would definitely not be injured.
