The Mermaid Apostle kept descending, and the two finally caught sight of the sea's surface.
A sense of unease suddenly rose from beneath the sea. The instant they recovered their magic power, the two immediately used teleportation magic to put some distance between themselves and it.
After returning to a place far from the cube, they flew high into the sky and looked down at the surging sea below.
"Kraken!" Mel used the Demon King's power to summon the ruler of the deep sea.
A massive octopus rushed toward them at incredible speed. Mel could clearly sense that Kraken had not gone near the cube.
That meant the unease from before had come from some other creature in the strait.
The problem was that, aside from the demonic whale and Kraken, the only other terrifying creature described in tales of the sea should have been an elusive demonized sea turtle.
All of this information had been gathered from horror stories about the ocean.
"No, it's not a sea turtle. Sea turtles can't move that fast!"
Mel stared intently at the sea, his Magic Perception piercing into the water like countless needles.
If it was a magical beast, then as the Demon King, he should have been able to control and command it directly, just as he commanded Kraken.
When the octopus's tentacles emerged from the sea, Mel landed directly atop one of them.
"Demon King, I don't know! That wasn't me just now!"
"Did you see anything? I can clearly feel that the thing beneath the sea isn't someone to be trifled with." Mel questioned Kraken.
"It seemed to be a merfolk. I saw scales."
"Merfolk?" Mel's brows drew together as he fell into confusion.
This was not where merfolk lived. It was hard to believe there could be demi-humans
