A few minutes ago, within the depths of the oceans surrounding the Heaven Port city, there were countless of dungeons merged together into a gigantic underwater ruin. Ancient cities drowned by the rising sea levels surrounded these dungeons, as the Miasma pouring out from them, over thousands of years, grew stronger and unrestrained as nobody ever defeated the monsters that spawned inside. Eventually, the dungeons slowly "melded" into a single and terrific Labyrinth.
The Ocean Abyss Labyrinth.
Unlike normal Dungeons, Labyrinths are special Dungeons of incredibly ridiculous sizes that can harbor countless floors inside and even different biomes altogether. However, within this Labyrinth, only water remained, and countless of monsters constantly emerged from within, eating one another constantly and growing stronger out of that.
Over the many thousands of years, the monsters here became so strong that even creatures of Ranks above 6 began to appear as if it was normal. However, amongst them all, there was one true ruler, the first that managed to reach Rank 6, then 7, then… 8! And went even beyond Initial Stage but reaching Peak Stage after fighting another Rank 8 Monster that tried to take over its rule within this area of the world's oceans.
It was an enormous sea snake, which once started as a small and humble little sea snake that feed on small fishes and crabs, which slowly reached the pinnacle of the food chain here through thousands of years, refining its own body and soul by feeding in the magical powers of the monsters it devoured, and developing its powers through evolution.
Eventually, it even managed to unlock the power of a pseudo-Dragon, while still being a Monster. It was well known that there were Monster Dragons as well as the Ancient Divine Dragons in this world. However, these monster dragons were originated from the dungeons and not from this world, and are, in theory, a completely different species, yet they share many similarities in power and abilities.
However, the Old Ruler of the Ocean's Abyss, after thousands of years of living in battles, has grown tired and old, and wanted to settle down. Over time, it found a suitable mate, another Giant Sea Snake, way weaker than her, but suitable enough for reproduction.
It is nature's call for living beings, even monsters, to one day reproduce and keep their lineage going on. The old ruler mated with a male she found and forgave his life, allowing him to take a small part of her territory as her gratitude for his seed. Later, she laid a single, enormous egg in the depths of the Labyrinth, which she has been keeping warm through thermal bents in the depths of the ocean, where warm water flows with sulfuric components, making the water warm and filled with nutrients. The egg resting near this place was ideal, with enough warm, it would develop well and hatch quickly.
The old mother, tired of a life of fighting, and with incredible strength, rested in the depths of the hardest labyrinth in this area of the world… for years, she slept peacefully, hibernating.
However, something suddenly happened.
TRUUUUUUMMMM….!
Her ten years nap was interrupted, as her eyes opened wide, she looked around, suddenly realizing the floor below started cracking and opening. The thermal bents opened and turned into gigantic cracks, where magma continued coming endlessly. Her egg suddenly fell off the floor of the dungeon as the dungeon cracked open like an egg.
She desperately grabbed her egg with the tip of her tail, managing to save the egg from falling into lava and dying. Her rage was evident in her roar, as she quickly placed the egg inside a bubble floating in the ocean and conjured a thousand barriers of spiraling water to protect it from anybody daring to take a bite of the egg of their ruler.
She was intelligent, however. She quickly realized something happened… someone provoked this. She was a monstrous being and lacked feelings like sapient entities in the surface, but her rage was evident! She quickly glanced into the surroundings, finding an enormous crack near the wall of stone in front of her, which led to the surface. She realized, without any problems at all, that somebody had hit the ground so hard it broke apart and almost killed her egg.
With rage, she moved forwards, her enormous presence made most of the monsters around her quickly escape in utter fear, her enormous and intimidating aura made her rage more than evident! She reached the walls, which were already repaired, and body slammed them with her gigantic body, roaring furiously.
BAAAM!
BAAAAAM!
The walls didn't budge, the pressure was evident, the weight was immense. However, her gigantic body of over two hundred meters was not something that would easily give up either. Without hesitating, she continued slamming the walls, breaking them apart and then…!
BAAAAAAAAMMM!
CRACK… CRACK…!
CRAAASH!
The walls budged, opening as ocean water quickly got in. The monstrous ruler entered the area, roaring furiously and swimming everywhere, her gigantic jaws captured the small monsters that tried to freeze her, defeating them all.
However, ultimately, she found herself nowhere to go, pushing up only hurt her head and the enormous rock didn't budge… Instead, to satiate her rage, she decided to throw it all against the small people she had mostly ignored through her life.
Surrounding Heaven Port, the ocean began to wave furiously, as bubbles started emerging from above, enormous bubbles. Some people looking into the beautiful ocean of the port suddenly noticed the waves becoming strangely twisted, as the shadows of a behemoth- no, of various, several behemoths all at once emerged. A gigantic ocean snake's eyes looked from within the depths, as other beasts, obeying the ruler's call, were brought here.
"Mommy, mommy, look! What's that?" A little wolf beast girl pointed the sea to her mother.
"Huh? That's… a monster in the sea?" Her mother wondered, suddenly opening her eyes wide open as the gigantic head of a sea snake emerged, opening its gigantic jaws and unleashing an enormous blast of boiling water!
BOOOOOOMMMM!!!
