Silence!
Unprecedented silence!
Those on the walls of Changlin City were all staring with their mouths agape, incredulously watching the scene unfolding before their eyes, many people gaping and desperately rubbing their eyes, wishing to confirm whether what they saw was real.
Oh my heavens!
This was a Demon King, possessing monstrous strength, a formidable ruler of a faction of monsters. Among the humans, perhaps only those powerhouses at the Seventh Rank level could kill such a being.
Moreover, even for the mighty figures of the current age at the Seventh Rank, killing a Demon King, even a newly promoted one, was supposed to take considerable effort and the casting of techniques.
Essentially, it was necessary to use the qi produced by the Demon Slayer's bloodline to perform techniques that would slay the Demon King.
Yet what Zhou Heng had done was completely different from the methods of a Demon Slayer.
