Feeling the oppressive power of the Chaos Spirit Ruins Sealing Heaven Array, Fen Xiao sneered, "How overconfident!"
This formation could indeed pose a threat to him, after all, he was now just a residual soul.
However, activating this formation consumes a massive amount of immortal power. The power of one Immortal King and one Mortal Immortal clearly couldn't fully unleash the formation's potential, let alone seal him.
Fen Xiao loudly shouted at this moment, "Burning Heaven and Boiling Sea!!!"
His body instantly erupted into even fiercer flames, clearly, he was burning his Divine Soul Power.
At the moment of burning his Divine Soul Power, this wisp of residual soul became even more transparent, looking as if it were about to disappear at any moment.
But even as this residual soul was very weak, it was nonetheless left by a Great Power, and the strength Fen Xiao exploded with was enough to crush an ordinary Immortal King.
