Epic of Summoner: Supreme Summoner System in the Apocalypse

-----

Demons! Creatures from myths and religions, which actually existed in other planes of existence, Dimensions.

The Infernal Gates that led to the Dimension of Demons connected to several other dimensions which had a close connection with it, however, there was no such thing as a connection to this dimension within Earth's dimension.

Nonetheless, when the Dimensional Convergence happened, Demons leaked into Earth just as much as any other entity from other dimensions.

The World of Demons had only sent a few armies of their lower ranked and lesser demons to scout the area, only to find that powerful groups of entities had already sent their own scouting teams, such as the Slarkobs and the Celestials.

Due to this, the powerful Infernal Entities that existed in this world had been wary of them, and had only pretended to have sent some swarms of demons as wild monsters than anything else.

However, due to unprecedented circumstances, these two major groups of invaders who were taking over the planet was suddenly stopped and slaughtered mercilessly by a third party, an army of powerful beings capable of fighting both parties at the same time and kill them both!

Who could these beings had been?

The powerful entities that dominated the Demon World were left speechless after learning these news, even more when they saw the planet itself closing the Dimensional Cracks that led to the Slarkobs and Celestial Worlds for the time being, quickly reducing the amount of foreign energies melding into the planet.

They had already see how the entities of the World of Beasts had decided to retreat as well, closing the Dimensional Crack as it didn't wanted to risk letting an enemy with such terrifying potential it could grow so strong in just a few days…

However, aside from the initial report, the Demon Entities that governed the Demon World were left in the blue.

Should they risk it and try to conquer this world to devour their rich Core, or simply abandon it?

The Demons had discussed this thoroughly but decided to send four members of their Lower Rank Elites, named Infernal Generals!

Infernal Generals were beings that had already reached a level of power similar if not a big higher than a Demigod, their Demonic Energy was rich, and their Demon Cores were overflowing with tremendous quantities of power.

Demonic Energy underwent changes after Demons were to evolve into higher ranks, becoming Infernal Energy, of a higher and even more powerful quality that could easily overpower Demon Energy users.

As the Elite of the Lower Ranked Demons, these four Generals stood at the pinnacle of the "mortal" Demons and had already transcended into Infernals.

The powerful entities that dominated the demon world had many other worlds to pick up and devour, due to this, they decided to employ these four powerful Infernal Generals alongside a few more swarms of Demons to conquer Earth, deciding that four Demigod-level Demons were more than enough to destroy anything that could defeat a Celestial King, a being at the peak of Pseudo Demi Deities and the powerful Motherships of the Slarkobs.

However, even if something unprecedented might happen, they could always pull back at any time, all of such hegemonies within these interdimensional worlds were filled with resources and overflowing power, they were the groups that governed these dimensions entirely, and had grown bored and stagnated after so long, the Dimensional Convergence offered the possibility of expand their worlds as interdimensional empires, conquering other worlds was something easy for such high-level worlds such as the Demon World, Celestials World, Beast World, and so on.

But of course, these did not know nor were completely aware that Earth possessed the power of a Player, a mortal gifted with the power of a Supreme System given by the Great One Above All Creation in a whim.

The Beast World, however, accurately predicted Gustav's existence as a Player, and decided to close the connection with Earth for the time being, possibly looking for other worlds to conquer that could be much easier to devour than something with a Player, which as long as you don't kill it, will continue to grow stronger without stopping.

The Demon World's leaders overlooked the planet earth greedily, but this was just one world of the many more within their plans. Several illusions representing these planets emerged before their demonic and supernatural existences, resembling holographic images.

In there, earth was but a small planet within the countless others where they had sent their armies and generals, and these generals and armies were nothing but the lesser entities they possessed…

Certainly, despite this, they had kept an eye in this particular planet because it had a being capable of fending off strong threats by itself, the planet had birthed a proper guardian, something that wasn't so rare, but it was rare when they were actually strong enough and effective.

However, in the great scheme of things, a single planet within the countless others they could conquer and devour wasn't much. Of course, worlds with life were their main targets, after all such worlds were the ones that could form cores to devour, life to assimilate or kill for essence, and more.

The large Red Tower that Gustav had seen come from the ground glowed with bright red colors, as it emanated a large amount of demonic energy.

From within four Infernal Generals had come from their original world, sent by their great leaders to defeat the threats of this world, and conquer it, offering its core to them.

The four Infernal Generals looked over the vast landscape, there were many strange areas around, spaces which were teleported from other alien worlds through the dimensional convergence…

Millions of Demons of all shapes and sizes, ranging from C-Rank up to SSS-Rank in power marched before them, their army had begun to expand.

"North seems to be emptied by that being that defeated the Slarkobs and Celestials, let us go to the south, these uncharted lands seem good enough as a starting point…"

As the Demon Swarm neared South America, a flashing light emerged from the skies.

"What's that?"

"A… spear?"
