The Dungeon entrance to the Boundless Abyss Dungeon wasn't a conventional and pretty one, no at all.
It wasn't a finely built entrance with a properly made stair and bricks.
It was but an enormous hole in the middle of nowhere.
Of course, it had some areas within it that spiraled downwards, where people were able to enter and walk through it to reach the depths.
However, not many people entered this place, as this dungeon had designed itself to attract bigger prey, mostly anything that was a giant monster.
So when the Dungeon detected that an enormous dragon with a powerful aura came flying towards it, it couldn't help but feel joy.
How long has it been since a big prey had come directly into its abyssal maws?
And it contained so much power! The Dungeon Core could feel the overflowing mana within this entity… it was decided, the dungeon will try to do everything it can to kill him!
If the Dungeon Core can manage to get its hands into the corpse of such a being, and quite possibly its soul too, it could absorb it and gain enough energy to rank up and finally cross the X-Rank Realm to reach the Divine Dungeon Realm!
Oh? But there was more… An X-Rank coming with it and… another Pseudo Demi Deity too!
It was a big challenge… and the Dungeon only had X-Rank monsters at most… but it also had traps, the ability to manipulate its own interior partially, and the ability to lure them with all sorts of monsters and types of creatures… whatever power they had, if the dungeon did it just right like it always has done it… perhaps, they would all die at the end! How glorious would it be!
Unaware that the consciousness of the Dungeon Core had already planned their demise, Chaos, Belphegor, and Abyss entered the Boundless Abyss Dungeon through its gigantic and gaping entrance, which was an enormous hole that extended for several kilometers in the middle of the wasteland.
Flash!
Chaos performed a spectacular full dive into the Dungeon, flying down its abyssal entrance as it used Dark Vision to see its interior in detail.
"From what I know about this place, the entrance is deep into this darkness, there will be a series of caves, each one leads to a different biome, but they are all interconnected," said Belphegor.
"I see, let's go then," said Chaos, nodding as he encompassed his body with his crimson-red bloodthirsty aura, flying at an incredible speed through the boundless abyss, reaching deeper and deeper.
"Woah! We are going so fast!" said Abyss, enjoying the ride.
"Indeed! My lord is amazing at flying already! Oh, they grow so fast…" said Belphegor, feeling nostalgic about Chaos of a few hours ago.
However, the relaxing ride quickly came to an end as the trio detected a sudden malicious presence! …No, many of them, dozens, hundreds!
"Lord Chaos, something is coming!" said Belphegor, as he conjured dozens of magic circles around him, he was quite good at Fire Magic!
"I can see them!" said Abyss, suddenly expanding her feminine humanoid form into a mass of miasma with many glowing yellow eyes, tentacles, and jaws!
"I already detected them… Chaotic Spears," said Chaos, as his crimson-red draconic eyes flashed with bright light, his entire body exuded pure chaotic miasma as he shaped them into spears of eternal darkness, firing them at the entities rushing towards him!
The creatures that emerged from the abyssal darkness down below were enormous flying mammal monsters, covered by black fur, who was blind and had large ears, accompanied by razor-sharp fangs inside their vicious and drooling jaws.
Their wings had thin membranes and long claws, flapping against the winds, and reaching higher altitudes, these creatures were S-Rank Giant Spectral Bats, a single one of them could easily decimate an entire town, and hundreds of them, an entire nation!
"Grryyyaaaarrrr!"
The beasts roared as they flapped their wings, flying incredibly quickly towards Chaos and his party of two, as they didn't detect the deadly fireballs and chaotic spears flying towards them!
Flash! Flash! Flash! Flash!
"GGGRYYAARR!"
"GRRUUOORR…!"
"GGRRAAOO…!"
The cries of agony of the flying beasts quickly began to fill the entire Boundless Abyss Dungeon, the first wave of monsters made by the Dungeon Core was quickly greeted by a terrible fate!
The fireballs quickly reached them as they began to burn alive, being reduced to grilled corpses within seconds! The sharp chaotic spears pierced their bodies and exploded in chains, decimating bats left and right!
Slash! Boom! Crash! Clash!
"Oho! What a sight!" laughed Belphegor, flying near the surviving bats as they desperately tried to kill him, Spectral Bats had the special ability to exert their own souls as spectral forms, releasing bullets made of the spectral soul against Belphegor, which could directly damage his soul!
However, the old blazing skull laughed, as he conjured a powerful spell!
"Gyahahah! Is that what you call a spectral attack? Look and learn! Pandemonium Ring!"
FLASH!
Suddenly, Belphegor's flames extended all around him, creating a gigantic ring of spectral red flames all around, which constantly began to rotate, annihilating the bats and burning them to a crisp!
The powerful attack was so massive that dozens of bats began to fall one after another, their measly spectral attacks easily dissipated after the deadly flames!
And amidst this blazing massacre, Belphegor laughed eerily, enjoying the sight!
Meanwhile, Chaos began to play around with his Skills.
"Blazing Stab and Storming Stab… Blazing Storm Claws."
CLAASH!
By combining fire and winds coming out of his claws through these two Skills, Chaos created a blazing storm from his mere claws, which he unleashed as powerful slashing attacks over the bats, slashing them into pieces and roasting them at the same time!
"Orc's Burly Physique, Orc's Wrathful Charge, Nether Worm's Razor-Sharp Teeth."
Chaos enhanced his physique and muscles, and then coated himself with sharp fangs and charged against the Bats like a blazing meteor, crushing the bats one by one into a pulp against the walls of the cave!
CRAASH!
"Hm, good enough," analyzed Chaos, while drinking blood through Bloodwork.
Meanwhile, Abyss was singing…
