He was in terrible pain. He had nothing to stop the assault on his dantian and body. His dragon scales, so powerful against his enemies before, were glass to just the projection in front of him.
Fiends were weak to him. Any doubt about the absurd strength he enjoyed against them had been hammered home in a single crushing defeat. Immortals were far more powerful than he had expected.
He had sparred with Lanbao and Linghu but they held back more than he had imagined. Lanbao also was instinctively reduced in strength due to their bloodline differences.
He had become arrogant or at least over confident in his ability to fight above his realm.
The source of his heart demon was so clear to him now. He believed he could win due to being a dragon and pioneer in his field of 6 elemental development. He had not become mad with power, but fallen for the trap of his success.
