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

After many introductions, Chaos got to know these former slaves that had their own lives, and who also brought more than he had gotten by just eating them. It seemed that these people might end up helping him a lot in the long run, as their abilities seemed useful and so did their knowledge and experience, something that Chaos couldn't take away from those he devoured.

He had begun to think more and more about the value of making new allies. However, he wasn't able to trust people up front, especially because he had just met them today, so for him to feel relaxed with people like this without the risk of betrayal, he had quickly used those soul contracts he created using his chaos magic and shaping it as chains.

However, he was not done yet for today, as he didn't want to waste any more time.

"Belphegor, please gather all the Orcs there are around the throne room, all of you, please accompany me," said Chaos, as the group of former slaves felt curious about what was Chaos calling them to the throne room for… Although most of them had already relaxed around him, they already began to think that he might have changed ideas and now wanted to eat them as snacks!

But that wasn't the case.

After a few minutes, Chaos saw the entire group of Orcs enter the throne room, from the strong ones qualified as warriors, who were mostly all women around their early twenties, to the old ones and even the young kids and babies…

And there were also the former slaves at his side.

"Welcome, I called you all here for a little experiment. I wanted to use Miasma to evolve you all. I am sure that you've already seen the other Monsters in my castle, they are all-powerful and had evolved from low-ranked monsters into the high-ranking creatures they are. All of you, I want to do the same for you too. This way, everyone can be stronger and therefore have an easier time surviving and adapting in this world," said Chaos.

The Orcs seemed eager, cheering for him, while the former slaves were a bit concerned.

"Then please, my Lord, let me be the first to be blessed by your powers," said Dura, walking towards Chaos.

Chaos nodded as he didn't mind her being first.

"Sure thing, Mutagenic Miasma," said Chaos, conjuring the spell he had created, which created a special miasma with very high mutagenic qualities within it, a bit of this black fog-like substance was enough to cover Dura's entire body.

Flash!

A second after, her entire body started to quickly mutate, as Dura felt as if her entire body was cracking and breaking apart, however, it was merely the power of evolving forcefully many ranks. As she was a flesh-living being, she was feeling more pain than those such as Will-o-wisps or Living Brooms could feel.

However, the pain only lasted but a few seconds before it fully disappeared, as a new and more powerful body was formed for Dura.

"Ah… Such power…"

The fog dissipated as Dura glanced at her figure, her figure had stayed mostly the same, her body was mature and slender, but also well-toned with strong and hard steel muscles, especially her thighs, which could easily crush a watermelon. However, her skin had suddenly turned from green to red! And her arms were now filled with fiery tattoos, while she had grown two black horns in the middle of her forehead. Chaos noticed that her face had become prettier as well, more refined and beautiful, and her eyes glowed with crimson-red and orange fieriness.

"Amazing, it worked well," said Chaos.

"Oh, Master… thank you so much for this power…! I will make sure to use it to serve you as much as I can!" said Dura, kneeling before Chaos.

Dura had evolved from a C-Rank Orc Warrioress into an SSS-Rank Fire Oni Amazoness Chieftain! Her power had multiplied several times by the grace of Chaos' amazing power, and she had even gained the power to conjure fire to enhance her powers, while her body temperature had also raised a lot.

Chaos continued to evolve the Orcs as they came. Not all the Orcs evolved into Oni, and those seemed rare. Only the strongest and healthiest seemed to tend towards becoming Onis, while the rest only became enhanced versions of Orcs, of course, the weakest ones were now A-Rank, so it was a substantial increase in power. Even the babies were evolved and became stronger. And due to this, they might now grow even faster than before.

All the Orcs were looking at their new and enhanced bodies, some of the warriors were seeing their newly acquired Oni elemental powers, such as Blue Onis, Black Onis, and even there were Gold Onis. Additionally, the elders of the tribe were rejuvenated after evolving by Chaos' miasma, and seemed to have gone back to their prime… It was truly a sight to behold.

After seeing such outstanding and insane powers, Natalia and the other former slaves were left in shock, they already knew Chaos was ridiculously powerful, but now, they were able to grasp but a small amount of his even greater powers, such as having the ability to evolve other beings! (although only once, repeated use of this spell seemed to not work anymore on already evolved targets).

"Now you're next…" said Chaos, looking at the former slaves rather eerily, it made chills run through their spines!

Natalia ended being the first to step in, as she seemed to be trembling a little bit.

"Don't worry, it might hurt, but it will make you stronger… I hope," said Chaos.

"Y-You hope?" she asked.

"I don't know if it can work on non-monsters yet, so you're the first for such an experiment… Anyways, good luck," said Chaos, as Natalia began to panic a bit…

"W-Wait! Uagh!"

Natalia tried to stop Chaos, but the miasma already took over her entire body like a black fog, warping her mind and body!
