「Above the underwater city!」
The battle between the Mermaid King and the Black Wing King had reached its climax. The surrounding seawater was churning violently.
The Black Wing King summoned his Battle Soul. It was also a humanoid Battle Soul, but it was tens of times larger than the Battle Soul of a Black Wing Guard! It loomed above his head like a mountain.
"Die, old scoundrel!"
With a furious roar from the Black Wing King, the Battle Soul, like a Grim Reaper, struck towards the Mermaid King.
"Hmph!"
The Mermaid King snorted coldly, his hands placed before his chest, swiftly forming seals.
"Ocean King Seal, kill!"
With his low shout, a golden seal burst from between his hands, colliding fiercely with the humanoid Battle Soul.
BANG!
Both were destroyed. The Black Wing King was flung away, his face slightly pale. The Mermaid King, however, spurted blood continually as he was sent flying!
