Epic of Summoner: Supreme Summoner System in the Apocalypse

-----

"Now, Gustav, use this power to defeat hits vicious parasite! He had been trying to devour this Dimension for eons now, his shadows had been slowly extending around my entire membrane, eliminate him before it is too late!" said the Dimensional Core, finally finding a proper vessel to all her power, it wouldn't be an exaggeration to say that Gustav might become a Dimensional Ruler!

Gustav and his summons, alongside Xijun, and his tamed pets merged into his body alongside his Spirit Beast Dragon all gathered their power together, as the constant summoning of their ultimate attack suddenly was strengthened by a billionth fold!

TRUUUUUUUMMM…!

CLAAAAASSSSSSHHHH!!!

"Nnggh?! Aghh…! I cannot… fight back?! T-This is the power of another Dimension?! Aggh… Y-You've… become a Dimensional Ruler?!" asked the Abyssal Dimension Dimensional Ruler in complete shock over the situation!

No on his wildest of dreams could he had guessed that Gustav would turn into such an entity, but it was all meticulously orchestrated by the Dimensional Core herself!

She helped Gustav evolve the Physique that could make a connection with her, and she also helped Gustav land into the Universe and the planet where the Dimensional Key was located.

The moment Gustav fended off the first wave of Dimensional Conquerors that she had already decided to turn him into her Dimensional Ruler, the one deserving of her power!

Crack… crack…

CRACK!

Enormous Dimensional Fractures emerged all around the Abyssal Dimension, as an endless wave of darkness and monstrous shadow beings fell over Gustav and his part, constantly trying to devour them and annihilate them from the face of the world, only to be greeted by enormous and all-consuming attacks that were completely logic-defying, and summoned billions of times per second!

BOOM! BOOM! BOOM! BOOM!

CRAACK!

Another fracture emerged in the Abyssal Dimension, as the Dimensional Ruler began to grow more and more desperate! It should had never tried to invade this dimension if something like this would had happened!

"All of you, unleash Plan B!"

However, he wasn't without a plan B!

All the powerful beings that had become his vessels within the Dimension of Gustav heard his orders as they used the power, he lend to them to break through space and time and create Dimensional Fractures as well!

His goal? He was going to flood this dimension with his endless shadow body and try to devour it from the inside out before he could get destroyed!

"Unggh…! T-This bastard is doing such a thing?!" asked the Dimensional Core, shocked!

"You thought I would die so easily, Dimensional Core?!" roared the Dimensional Ruler, as his endless darkness began to suddenly overwhelm all of Gustav's Dimension, devouring the very fabric of reality within it!

"And did you thought that I, as a Summoner, wouldn't be able to deal with such a little problem now that I have Dimensional Power with me?" asked Gustav.

"EH?!" the Dimensional Ruler suddenly felt an enormous feeling of dread!

Gustav within his Divine Realm waved his hands as he spent a pile of Orbs, he had accumulated this entire time, but he also infused Dimensional Energy into the very Gacha, and hacked it!

"Gacha Summon!"

FLAAAAAAAASSSSHHH!

Suddenly, hundreds of Summoning Jewels began to emerge one after another around the entire of Gustav's Dimension, summoning all sorts of entities that were made by fusing Gustav's fictional characters from his novels!

Hundreds- no, thousands of these powerful entities continued to fuse with one another and multiply as Gustav constantly used Dimensional to hijack his own System and suddenly take complete control over the very core of its functions!

The Great One Above All Creation, using his authority, was about to revoke Gustav of his power!

However, just as he was to try that Gustav hacked his own System and made it his own power, an extension of his very will!

"Impossible! He stole the System from me?!"

The old man roared in complete and utter surprise!

"Dimensional Core, Gaia, Mars, and all the planets, combine!"

Gustav suddenly created a connection with Gaia, Mars, the Dimensional Core, and the other planets of his Divine Realm…

But for what reason?

All of the planets suddenly resonated with their World Origin Core energy, infusing themselves into Gustav.

Gustav then redirected this power and quickly made a connection with many planets all around his own Dimension.

And then, from the planets to the stars, the black holes, the galaxy cores, and then, the universal cores!

FLAAAASH!

Countless cores all across his dimension began to resonate through his special method, using the very planets and the star of his solar system as his starting point and pillar for such dimensional connection!

Something that the Dimensional Core had never been capable of doing was done in mere seconds, unify all the independent cores around her entire body!

Her power suddenly skyrocketed by a quadrillionth fold, and beyond!

"So many Cores resonating within me, all willing to cooperate?! Gustav…! You've done what I have not been able to do all this time…" muttered the Dimensional Core.

"I am actually surprised in myself that it actually worked!" laughed Gustav.

Gustav's endless summons merged with his gacha summons constantly, becoming giant entities of various powers merged together, they began to fill the Dimension and attack the invaders, pushing them all back to the Abyssal Dimension, and closing the Dimensional Fractures, while healing them by using their very bodies!

The entire Dimension felt relieved now as the Dimensional Fractures started to heal one after another, her power was now stabilizing and not being drained away by the Dimensional Ruler of the Abyssal Dimension!

Meanwhile, inside of this entity's dimension, Gustav's summons were also powering up greatly and unleashing incredibly devastating attacks combined with Gustav's endless onslaught of summoned attacks!

"Primordial Cosmic Chaos!" roared Kireina, as she unlashed the power of her primordial chaos in all its splendor, now that she had the power of a whole Dimension, this was more than possible!

TRUUUUUMMMM…!

As massive fracture in the dimension emerged as endless all-consuming chaos began to spread everywhere, turning into countless caterpillars that began to devour the Fabric of Reality within the Dimensional Membrane, growing fat, and then turning into cocoons to later evolving into glorious Primordial Chaos butterflies that started to fly everywhere, consuming everything!
