While Ares suffered great losses due to such an unexpectedly overwhelming explosion empowered by primal forces above unigins' reach, Felix knew that it wasn't going to end well for him.
He saw it from a mile away that the confrontation was going to end horribly and since he could not move or use his laws to defend himself, he was left with only one option.
Accept his death and plan to minimize the losses...For unigins, death wasn't the end.
Thus, right before the explosion occurred, Felix had done something to himself and the tenants.
***
A couple of hours earlier, right before the explosion...
'Everyone! Move to Asna's core!'
Felix shouted with a solemn expression as he watched his soul barrier crashing at a rapid rate.
Rumble! Rumble!
'I can't believe your death happened because of you.'
