Capítulo 1602: Special Ability.

Aeternus observed to himself and the other clones, "These threads can heal and restore themselves quickly. If I don't overwhelm the barrier instantly, I won't be able to destroy it."

He can see that he will need to destroy all the threads at once to destroy the seal. That will require a power capable of destroying 100,000 Supreme Powers at once. Such a thing doesn't exist. At least not on the light side of the void universe. 

"This is interesting." He said, as he observed the flickering barrier. "How did they make it work?"

A world god is required to destroy the seal. That much is certain. The alternative is to kill the Supreme Tyrants that made the seal one by one. So he can't believe that a couple of sovereigns managed to come up with something like that.
