Arthur's descent to the ground was accompanied by his faux true voice calling out the name of his technique.
One he had created in battle against three Epic Realm Celestials, back when he was but a mere Grandmaster.
The ground convulsed beneath him and then enormous waves of purple energy surged outward in all directions, covering hundreds of metres of distance in each second.
The Divine Human Soldiers on the ground all tried to defend, but it was pointless. The destruction law energy washed over their pitiful attempts at defence and ground them down to nothingness, before going on to do the same to their bodies.
Efforts at defence crumbled before the onslaught of power as the surge dismantled barriers and with merciless efficiency, obliterated flesh and soul.
It was even more effective on them as they possessed Divine Factors!
Master and Grandmaster realm existences succumbed and perished within seconds.
