How the Laine people managed to escape from there, Amberser did not know, all he knew was that it wasn't going to be easy to get through from the seabed.
Even if he dove deep into the ocean, avoiding the terrifying thunder from above, the seabed still had countless whirlpools, and these strange currents had shattered the seabed into pieces, much like a labyrinth.
He either had to navigate through the rocky layers of the seabed labyrinth or charge directly against the whirlpools above, to see whether the force of the water was stronger or if his own body was tougher.
This was definitely not a natural environment, it was either the masterpiece of a Deity or the creation of a Legendary Mage with a twisted sense of humor, using the World Weaving Technique.
