The ocean trench was pitch-black as ink and utterly silent. The rocks lining the canyon were all black, without so much as a tiny fish, sea snail, or seashell...
The canyon was immense, spanning tens of thousands of feet. Enormous caves dotted the sheer cliffs on either side, and within them, powerful presences could vaguely be sensed, exuding overbearing auras...
Suddenly!
An extraordinarily peculiar stench spread through the trench, churning through the seawater like streams of gray mist...
All at once.
Roar!! An astonishing, furious Demon Beast roar erupted from the caves. Pairs of eyes glowing blue or blood-red stirred within cave after cave, radiating intensely suffocating auras...
Then!
Whoosh!!! Terrifying waves surged as enormous Sea Demons emerged from the caves one after another. Suffocating Sea Demons filled the entire canyon, charging like a tide toward that strange stench...
The Sea Demons grew wildly agitated. Their enormous charging bodies whipped up terrifying tides and sprays, filling the entire ocean trench with the roar of fearsome waves.
As the Sea Demons continued their charge...
In an underwater valley ahead of the trench, purple-blue flowers grew in the center, giving off the scent that drove the Sea Demons mad.
Roar, roar!! The Sea Demons howled with frenzied excitement and charged madly into the valley...
Those purple-blue flowers seemed to hold an irresistible allure for the Sea Demons, and countless Sea Demons rushed toward them in utter frenzy!
As the Sea Demons charged into the valley!
All at once!
Boom! Boom! Boom!!! Earth-shaking explosions rang out as pillars of water, runes, and spirit light erupted around the underwater valley, forming an enormous misty Light Barrier that instantly trapped countless Sea Demons inside...
Yet the Sea Demons seemed not to notice, fighting madly over the purple-blue flowers...
A terrifying battle between Sea Demons erupted
