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

The Elder Brain was the supreme leader of the Mindflayers, a powerful being made out of the brains of many of their eldest members whose bodies were already too old to move their enormous brains. These brains converged together into a new lifeform, some sort of powerful eldritch god, a giant brain made of many smaller brains, who had his own consciousness created by the convergence of the many other consciousness that the Mindflayers had.

A powerful and terrifying being said to be able to manipulate the minds of the entire planet where it inhabited, it could easily dominate entire planets by merely reaching them, but it often remained on his hideout. Aside from his enormous mind powers, his body was frail and needed a pool of brine to maintain himself well.

Even though it had powers that already reached the level of a Great God, they were mostly trapped inside their own hideouts, and moving out was often a monumental task that was only made in desperate occasions, and with a proper amount of preparation.

The Elder Brain was unable to sense anything even with his amazing powers, and when the entire ordeal started, he was already growing rather nervous. His powers were incredible, but what he could do was very limited!

"Ggrrr…! Shut up you useless tentacles! Go defend my territory! If things gets to the worse possible scenario, I will have to escape, so make sure to distract the enemy until then- EH?! T-THIS IS…!"

BOOOOOOMMMM!!!

However, against his own expectations, things were not going to go according to his plans. An enormous object suddenly flew down from the sky, the very same spaceship that it was attacking the fleets defending the planet!

The entire spaceship was incredibly resilient because it was Rust himself, a living being of his own that could reinforce his defenses to amazing levels using cosmic energy and divine energy combined! Using his enormous body and weight, he fell down into the planet's surface and then dug through the ground, reaching the underground city in an instant, and falling right over the temple where the six Mind Gods and the Elder Brain were discussing what to do!

CRAAAAASSSHH!

The ceiling quickly shattered into pieces, as the enormous debris fell over the Gods and the Elder Brain, everyone generated Psionic Barriers and easily shielded themselves from the damage that these debris could even make, however, the enormous spaceship falling over them could not be properly stopped!

BOOOOMMM!!!

The giant spaceship-shaped metal slime, Rust, clashed over the Mind Gods and the Elder Brain's barriers, breaking some of them and using his enormous weight to crush them!

Barely, the Elder Brain and half the Mind Gods survived, running away from the area of the destruction. The Elder Brain had a hard time moving around as he would dry out without his pool of brine, but he could still keep some hours fighting without being on it. The Elder Brain used Telekinesis to lift himself and generated a bubble made out of Psionic Barriers to protect himself.

"Uunnggh…! Help!"

"Aagh! M-My body…"

Some of the Mind Gods that were unable to escape in time were crushed and their bodies were shredded, barely alive thanks to their divine souls, they were desperately asking for help to the Elder Brain and the Mind Gods, but they were not giving them any attention as a threat bigger than the spaceship itself emerged out of it, a dark shadow covered in a blood aura, the scent of Vampires covered the entire ruins of the temple as the Elder Brain was left speechless.

"Y-You're a Vampire?! You dare break our treaty?!" Asked the Elder Brain, as he looked at the figure of Jakob emerging from the spaceship!

"Yes, I, Jakob, declare war to all Mindflayers!" Said Jakob. "I won't allow you filth to live in our territories anymore!"

"You dare do such a foolish thing, you stupid vampire?!" Roared the Mind Gods, as the Elder Brain felt like he would be gritting his teeth if he had them.

Desperately, he quickly contacted the colonies of Mindflayers spread around the Galaxy, alongside some of his allied and even enemy Elder Brains, he had to tell these news to all of them quickly so they could unify against this new common enemy!

"To think that after eons of our treaty of peace, you've dared to attack us and even attempt to exterminate us, Vampires! I have already contacted all the other Mindflayers Colonies across the galaxy through our Telepathic Network, you don't realize the catastrophe that we'll unleash against your family!" Roared the Elder Brain in utter and wrathful anger.

Jakob smiled.

"Good." He said. The Elder Brain felt a strange and eerie presence from within. Although he had only met and made some transactions with this Jakob before, he never knew of such an insane facet of this Vampire, to think that he would storm his planet and even destroy his Mindflayers all because of merely being disgusted against them? Even when they had been in peace for so long without any problems whatsoever?

"A-Are you really…!?" Asked the Elder Brain, but it was too late, Jakob summoned his Soul Weapon, Scarlet, as an enormous spear of red color emerged. The Vampire flew towards the Elder Brain and immediately attempted to break his barrier with an enormous showcase of powerful techniques, the swing of his spear was replicated thousands of times over in mere seconds, clashing and cracking his barrier!

CLASH! CLASH! CLASH! CLASH!

"N-Nggh…! So fast..! This is the speed and power of a Great God-Realm Vampire…!" Muttered the Elder Brain, as he quickly attempted to fight back. "You're just too foolish to get close to someone as me, a master of minds! MIND CAGE!"

The Elder Brain immediately tried to attack Jakob by using the power of Mind Cage, one of his strongest techniques capable of caging the mind of a foe inside a different mind scape, where he can easily devour their minds and leave their bodies completely mindless, ready to be eaten as well.

However, a sudden protection activated within Jakob's brain, protecting him from the power of Mind Cage!

FLASH!

The Elder Brain's attack was ineffective.

"Impossible…!"
