Demon Queen Rebirth: I Reincarnated as a Living Armor?!

-----

Yggdrasil noticed that something had happened, the Celestial invading the planet had suddenly disappeared! The Split souls and her mothers had somehow been able to repel it…

She looked towards the outer space, as a sudden crack in space and time opened, and a gargantuan black mech fell from the skies into the depths of the ocean of the planet.

SPLAAAAASH!

"W-What the heck? Are they okay?!"

Yggdrasil felt immediately alarmed, this was not okay at all, something might had happened to her mothers and the split souls, and she was really worried about them, quickly spreading her roots under the water, as she had another Tree Body in the middle of this ocean, quickly moving there to see if they were alright.

Meanwhile, a gigantic black mech submerged into the depths of the water of Eden, causing a gigantic tremor in the middle of the oceans that was even felt all around the planet…

The consciousness of the minds merging within the mech suddenly felt an enlightenment as their Existence Realms suddenly skyrocketed, and everyone suddenly reached a Realm beyond Supreme Gods… the Realm of those that devour whole planets.

The split souls already had the potential to reach it, their accumulated power was that of two whole planets after all, but they were never able to fully unlock it because they required to level up more, but now that they acquired a gigantic amount of power from eating the Celestial, they gained enough strength to break through this progression wall in an instant, and because everybody was fused together, all this power was shared with everyone, and all of them jumped to World-Devourer Realm as well, even Aurora who had yet to reach Supreme Goddess Realm jumped that entire Realm in a single sitting!

"This power… incredible… So this is what it feels to devour one of those bastards…" sighed Aurora. "However, that was… very, very close… I once more thought I would die. For like the third time."

"Ah, don't joke with something like that…" sighed Ervas. "But indeed… We have gained unprecedented power, and these memories of the Celestial… they're quite interesting… I think we have finally learned the location of Samsara."

"This power… So this is what it feels to become a World Devourer-Realm entity?" wondered Veronica. "I see… And Samsara's Location, huh? Using Aurora's powers, we could… even teleport there."

The split souls began to consider such a possibility, but Samsara was too strong, they were not able to stand a chance against him even if they used their newfound power.

And also, they still had to completely assimilate this power… as of now, their divine realms and their very souls and divinities were evolving, all five of them were evolving together into a whole new entity, a World Devourer.

Within the divine realm of the split souls, their World Soul Core suddenly began to shine the brightest as it absorbed all the energy it gained from them devouring the Celestial and infused it into the gigantic Yggdrasil Tree holding this enormous core!

FLAAAASH!

The core began to glow with bright light, and began to rotate, while the tree continued to grow bigger and bigger, and through its branches and roots, it infused enormous quantities of World Source Energy into each of the worlds that this Tree had, each world grew larger and larger, until they all… suddenly exploded.

BOOM!!!

And then, something mystical, which they had never seen before happened, all the worlds fused together into one, an enormous and ever-expanding fused world!

"W-What is this?!" asked Veronica in shock.

"I-It is happening so fast that I can barely see what's truly happening…" said Ervas.

The tree suddenly began the pillar of this gigantic world, as its roots maintained it afloat, while Helheim remained the same, but expanded through countless new underground areas, while the Soul Core flew down, into the depths of the fused world, and remained at its center. Becoming, essentially, a World Core.

The entire Divine Realm had evolved, and just as their new Existence Realm indicated, it had become a World by itself, no longer a simple Divine Realm!

This was the World Devourer's internal space, named Internal World!

And alongside this, the gigantic Internal World of the Celestial they devoured fused with their Internal World was well, making it bigger and more grandiose than ever…

The outer space area of the Internal World became more and more expansive, as flashes of light, small stars that were just hundreds of kilometers big balls of fire and light emerged one after another, and they most likely had the potential to become true stars eventually.

The split souls admired such a beauty as it continued its course of creation, the enormous expanse continued endlessly as it began to expand more and more, until inside of both of their souls, a space by itself emerged, it felt as if a pocket universe had just begun its creation, but as of now it was only as big as a cosmic nebula with a small world in the middle of it, but this world might be the beginning of many more to come in the future…

The World Source Energy that their World generated was infused into their merged souls and the mechanical physical body, ensuing a rapid evolution into a new stage of power… both had now become the World Devourers of Life and Death!

Meanwhile, Aurora, Juliette, and Anastacia's Internal Worlds also developed, each one of the three had their own worlds inside of their souls now, although not as enormous as the split souls, they were still big and wondrous, producing constant World Source Energy to give them the power to assimilate and then settle down the enormous quantity of power they had suddenly acquired.

And as their powers were evolving and so did the System, a mass of roots hit the giant mech loudly.

CLAAAANK!

"W-What was that?!" Asked Veronica in fear.

"Oh, that's Yggdrasil." Said Ervas.

"Are you okay? Hello?" Asked Yggdrasil worriedly.

FLASH!

Suddenly, five bodies emerged out of the mech, as the giant titan was left in the underwater, Veronica, Ervas, Aurora, Juliette, and Anastacia emerged, now overflowing with new World Source Energy within them.

However, in another area of the planet, the fight was far from over…
