Epic of Vampire Dragon: Reborn as a Vampire Dragon with a System

The tiny Dungeon Core had suddenly popped into existence over the accumulation of miasma.

The first thought it had was the universal desire for expansion that all Dungeon Cores are born with.

It had intelligence, but it seemed primitive at best… It quickly flew into the underground, and like a seed, it planted itself into the ground.

It gathered energy and miasma, and after a few hours, a complete and fantastical thing happened, the dungeon began to form, the earth moved away as bricks emerged out of thin air, torches, and even monsters appeared…

However, it wanted to expand more. But it was limited by energy and resources, it could not easily expand as much as it wanted anymore…

Like any other dungeon that has ever been born, it desired to expand and grow bigger, to cover the entire planet- no, the entire galaxy!

Dungeons were simple life forms that improved for this sole and primitive desire which they all are born with.

However, it usually depends on their desires that they can expand more, sometimes, as time goes by, they change and gain new desires. But all Dungeons gain a new desire after the first one…

The desire of eating.

They want to eat, to appease the hunger for power and energy they all have, so they must sacrifice the very monsters they gave birth to, while also forcing them to reproduce by themselves to generate more nourishment. Usually, this process is slow, however.

This is why dungeons become immense structures, they desire to bring forth meals inside of their very stomachs, they generate riches to entice them, and monsters and traps to kill them.

They can absorb the corpses and convert their organic matter and souls into energy, and gain more power to expand further.

Of course, monsters are sometimes faster.

However, as long as they can absorb the souls, they gain a moderately high amount of energy, often leaving the physical bodies to the monsters that killed them.

But dungeons such as the Boundless Abyss are highly intelligent, desiring to even devour the physical body of Chaos. In which case, they employ the Dungeon's Will by expending energy, using it, they can control the monsters inside and also the dungeon structure itself.

But of course, for the little dungeon core that emerged out of miasma produced by Chaos near his castle, there was no such power, it lacked sufficient energy.

After a few hours of being born, it was impatient to get a meal, it had set up multiple deadly monsters and traps, although it decided to not spend energy making riches, as it found them useless.

And then, finally, a group came inside the dungeon!

But it was doing everything wrong… for it! It was eating the monsters, and rushing inside without stopping. Somehow, the traps were not working against them either, or merely didn't even damage them.

Multiple times Chaos stepped into a trap and was bathed in boiling oil, but that didn't really cause any damage to him, and Abyss would lick his entire body to clean him with her tongue and slimy body after that… She was a very serviceable maid and couldn't tolerate seeing her master getting nasty.

The Dungeon Core began to feel frustrated and even fearful, as Chaos reached the last floor…

It quickly used all the leftover energy it had and infused it into the last boss, enhancing its power to its limits!

FLASH!

BOOM!

The moment Chaos broke apart the gate to the dungeon boss, what he found inside was… a dragon!

A dragon coated in black scales, gleaming crimson-red eyes, and possessing enormous black wings with red membranes… it exuded a high amount of energy, it was a peak X-Rank monster, the same level of power as the Blazing Fire Dragon that Chaos fought before! It even had a similar size, of around 40 meters tall, the hall of the boss was very big too, so it could easily move around!

And even more, Chaos felt like something deep down had infused the creature with more power and forced an evolution similar to how he was able to force evolutions in others.

The monstrous creature was… a Chaos Dragon, an X-Rank Monster!

"Amazing… this is a dragon! Here from all places?! And such might…! Peak X-Rank!" said Belphegor.

"Woah… it kind of looks like my lord's dragon form," said Abyss.

"Such might… My lord, shall we fight it together?" asked Dura.

"I can't help but feel a bit overwhelmed…" said Natalia.

"No, I will fight it alone. This is perfect, I can test my new abilities and the power I've gained since defeating the Blazing Fire Dragon," said Chaos.

Everyone obediently nodded, as they moved outside of the room and watched as Chaos walked towards the black-scaled beast, whose crimson-red eyes gleamed with malice as they inspected the invader.

"GRROOOAARRR!"

The dragon roared, as Chaos exploded in black smog and black flames, quickly emerging as a giant dragon, it was way bigger than his usual 20-meter-size now! As he was now almost reaching the 40 meters of the Chaos Dragon!

"Impressive, my lord's dragon form has grown bigger!" said Belphegor.

"His size has doubled!" said Abyss.

"Amazing…" said Dura.

"That's my lord for you!" said Jack.

"Go for it, master~!" said Lilith.

"Crush it!" said Ifrit.

It seemed that Chaos had a whole team of cheerleaders cheering for him, which made him feel a bit embarrassed, but nonetheless, he roared back at the Chaos Dragon as both of their crimson-red eyes flashed with dreadful light.

"RRRROOAAARR!"

FLAAASH!

At the same time that he roared, Chaos released a deadly breath attack combining the fire breath of the blazing fire dragon with the power of his chaos and nether breaths, unleashing a Black Chaos Nether Flame Breath!

The Chaos Dragon was surprised by it, as it quickly ducked and evaded in time, the powerful breath attack hitting the wall behind it and making a loud explosion, spreading the deadly flames all around…!

BOOOM!!!

CLASH!

The Chaos Dragon enhanced its body and leaped towards Chaos while unleashing its Aura of Chaos Attribute!
