There were three possibilities.
The first was that Angel Yan's attack had posed no threat whatsoever to Death Carl and had not even broken through his defenses, but that was obviously impossible.
Death Carl's strength did not lie in his body's defensive or offensive power. Nor could he possibly ignore an attack from Angel Yan, who already possessed a Fifth Generation Divine Body.
The second possibility was that Angel Yan's attack had never actually struck Death Carl. The two existed in completely different dimensions. It looked as though the attack had covered Death Carl, but in truth, that was merely an illusory body and had no effect on Carl himself.
Tony considered this the most likely possibility. Death Carl's Phantom Body had displayed precisely this sort of trait. He had previously believed Death Carl's Phantom Body was similar in constitution to Void Creatures, or perhaps identical in essence, but now it seemed that was not the case.
If they were the same, there was no reason Angel Yan's attacks could affect those Void Creatures yet have no effect on Death Carl.
The final possibility was that Death Carl had indeed been covered by Angel Yan's attack, and his Phantom Body had not evaded it. It was simply that Angel Yan's earlier ability possessed a certain conceptual bias. Traits inherent to the very concept of "angels," such as "Justice" and "Radiance," held absolute destructive power over "Evil," "sin," and "darkness." But so long as something fit an angel's definition of goodness—"Justice," "Radiance," "kindness," and "mercy"—it would not be harmed.
When Su Yunqing had fused with the blood of a Twelve-Winged Angel from the Western Magic World, she had awakened a similar ability. It was hardly strange for Angel Yan to possess it as well.
