Jiang Fan stood on high, overlooking the entire scene.
He took in the battle situations of the Four Great Sects at a glance.
The other three sects, even if they chopped the Dead Corpse Puppets into powder, it was to no avail.
But the True Thunder Sect only needed lightning to shatter the deathly aura, and no matter how intact the Dead Corpse Puppets' bodies were, they couldn't move on the spot.
This was enough to explain.
The deathly aura was the key to their movements.
This was not a new discovery.
Whether experimenting on Little Demon Beasts previously.
Or burning the Dead Corpse Army afterwards.
They could all find that once the deathly aura of these Dead Corpse Puppets evaporated, they would lose their mobility.
It was just that.
In their first direct confrontation with the Dead Corpse Army, they were too nervous.
They only focused on fighting the Dead Corpse Puppets but neglected their only vital weakness, the deathly aura.
And this shout.
