Vampire Overlord System in the Apocalypse

-----

Within the confines of the universe, an enormous technological structure of alien origins traversed through the layers of space-time, slowly but steadily reaching their destination.

The figures within this structure had different shapes and sizes.

Some were humanoid in shape, others resembled masses of tentacles, and others large insects.

But they were all wearing special full-body armors made from materials containing immense strength and resilience.

Their transcendental souls emanated an air of colorful and immense power, each one of them was a being whose strength could not be easily comprehended.

They glanced at a holographic projection, Earth.

"Although we cannot carry ourselves directly there, as our souls would warp the spatial layers and could even cause a black hole to emerge and engulf the planet, we can at the very least begin to send the things we have prepared beforehand." Said one of such entities.

"It should be possible to send a few dozen of Mana Meteors there. The Mechanicals are still preparing, but in a few days we should be able to send them as well." Said another entity.

"Very well, open the wormhole."

A third entity commanded the rest, as a sudden hole in space itself emerged at another area of their technological spaceship, where another entity threw large pieces of crystallized mana.

"The wormhole would break if we touched it, be careful." Said an entity at its side.

"You don\'t need to be overly cautious either…" answered the entity, sending the last meteor towards the wormhole by using some kind of telekinesis-like force.

"They had been sent."

"Very well, now we shall wait. With this, more Gates should emerge in the world, and possibly those above the level of power these measly mortals have achieved. I believe this could be enough to wipe out the majority of them."

"After that, the Mechanicals will wipe out the rest, and then if that is not enough, we can send the Raid Beasts."

"Indeed. Everything shall go according to our master\'s desires."

"I am sorry, System Master, but this world shall be ours…"

"Wait, what about the divine entity within Earth\'s Exosphere?" asked an entity, interrupting. 

"Oh? The entity was born from the accumulation of Mana from the beliefs of those mortals over thousands of years. It is an incredibly young Divine Entity, we could even capture it and use it to refine materials."

"Even then, wouldn\'t it be strong enough to deal with the Mechanicals and Raid Beasts?"

"Possibly, but even as a Divine Entity, it cannot be everywhere… As long as we keep pressuring it, it will give in. Furthermore, when the waves of miasma hit it, the entity weakened greatly."

"And by the intervention of the System Master and the shift of attention into the System, it had weakened even more…"

"Nonetheless, let us proceed with cautiousness… Lucifer and the System Master are dangerous inter-galactic entities who are always together, if they notice us, we will have to retreat…"

"Luckily, the System Master seems to have become weakened after having suffered an attack from the Child of Chaos, that he named Kireina."

"How ironic… Well, let us use such opportunity then."

"Although the System Master might not be strong enough to stop all of us, it is strong enough to do a lot of things, we might risk resources by pointlessly fighting him."

"Lucifer, in the other part, is only but a vessel of the original one, as the original Lucifer cannot leave the Gates of Hell, the interdimensional plane where it was sealed by The One…"

"Only but a Vessel but it had already almost mastered the Law of Space-Time… How troublesome."

"But this world\'s Origin Core shall be ours, just as many have been!"

"Our Master will rejoice…"

…

Meanwhile, within the exosphere of Earth, a special space named Divine Realm rested peacefully.

This place unknown by all living beings in this world harbored the strongest entity that Earth has ever produced, a Divine Entity.

The Divine Entity, formed by the beliefs of humanity since their birth and intelligence has been shaping itself into countless minds and forms, always taking the form of the figures humans believed and held faith towards.

After many years, it ended becoming an immense colony of different minds, all connected by a single divine soul, formed by the refinement of the enormous quantities of mana that humans unknowingly infused into their prayers, beliefs, and faith.

This entity, however, felt ashamed of its own existence.

Born to protect its creators, humanity, it failed miserably.

The waves of Miasma produced by the crossing of the Child of Chaos through the Spatial Layers created tremendous destruction, and not even this Divine Entity could do much against such overwhelming and corrupted energy.

It shielded most of it is power, but the residual miasma still impacted Earth, provoking the apocalypse and the surge of gates towards dungeons.

However, if it had not shielded it, the entire world would have been tainted in the black and oozy miasma, and no humans would be left at all.

At least, it had managed to protect a small speck of humanity…

By using the help of the System Master, an entity that contacted it before this happened, it managed to set up a special System to enhance the strength of humanity so they could be able to survive against the apocalypse and dungeons.

However, it never knew that the true intentions behind all of this were others and that the System Master did not do such things out of pure goodwill.

The entity, that was resting within its Divine Realm to recover strength suddenly felt a disturbance in the spatial layers, as a small wormhole emerged before it could do anything to stop it.

The entity\'s various minds saw with horror as giant crystalized mana jewels fell over the surface of Earth, filling it with more Mana… and provoking the beginning of a new era, an era where even larger and stronger Gates would soon emerge.

"Damn it! Now, what can we do?"

"It is hopeless… Ooh…"

"Humanity has caused its own destruction, let them die and suffer for their own sins!"

"Silence, humanity created us, we must protect it!"

"But we have failed miserably…"

"The System Master has not come to help us either…"

"He has broken the promise…!"

"Damned alien!"

"I told you! We should have not trusted him!"

"All of you are too naïve, fools."

"The System is constantly draining the mana from Humanity, we are weakening!"

"It was a trap all along! IT WAS A TRAP!"

"No, we must trust him, he had good intentions, I was able to feel them!"

"You are too pure and stupid, shut up!"

"By buddha, all of you should behave a bit…"

"Is there any other hope?"

"We don\'t know. We must use our connection with the System to find a way out of this situation…"

"But how did this wormhole emerged?"

"Through witchcraft, of course! Burn all the witches!"

"Don\'t listen to him…"

"Could an enemy be targeting us from afar? Why does it want the world to be filled with even more mana and monsters?"

"Another entity is desiring this world?"

"Our home!"

"Why must we suffer such a fate? We should give up and escape into space…"

"No, we can\'t leave our creators alone!"

"We have to find a way… to save them!"

"Such hopeless and meaningless dreams… let them all die…"

As the multiple minds spoke chaotically, they suddenly felt an anomaly amongst the many Humans connected to the System.

"This… a Blood Core?"
