[ "Demonic Emperor Sword: Cataclysmic Destruction" ]
From my memory fragment of the Emperor of Destruction, this was one of the skills that contain absolute destructive properties.
Unlike Extermination Blast, Demonic Emperor Sword: Cataclysmic Destruction does not spread the power. The beam focuses on a single point and, upon contact, causes a colossal explosion.
-CRACK!
The sword broke right after launching the attack. The sword was a Rank-B artifact, even so, it could not stay intact after storing the amount of Dark energy needed to use this skill.
-BLARGH! -THUD!
Zero's body took an unbelievable troll to execute that skill. It was already a miracle that he was able to stand after using Demonic Emperor Sword: Extermination Blast.
Zero completely fell down with all his organs wrecked. Every cell in his body was screaming in pain.
