They had just witnessed Brother Cheng using fourteen Sword Hearts.
And they were all at the level of Sword Master.
This had already shattered the limits of their understanding.
And now, the legendary strongest Life and Death Sword Heart appeared!
"How is this possible..."
"What on earth happened over on the Immortal Realm side while we were away?"
"How could such a divine being appear among Sword Cultivators?"
Cang Luo Demon Emperor muttered to himself, unable to maintain his previous calm demeanor.
As for the other Quasi-Emperors, they were all in a dazed state.
They could understand each Sword Heart.
The surging Immortal Power was also familiar to them.
But seeing them all combined in one person was truly far beyond their comprehension.
Jin Ao had no idea what he was about to face.
He thought the gray mist was just the strong at the end of its strength.
No matter how strong it was, it couldn't surpass the previous Rainbow Extreme and Extremely Dark offenses.
