Vampire Overlord System in the Apocalypse

-----

Noah managed to grab his subordinates with tentacles made off his coagulated blood, resembling jelly or slime, and flew high into the air, before the Bat could destroy the boulder, and hiding beneath the debris of the boulder!

"Growl?!"

The bat was surprised to not find anything, as its sharp senses quickly noticed that Noah's group was above its head!

Noah activated the Blood Weapon Creation Skill and his Poisonous Blood Skill, using Poisonous Blood and Mana to generate Poisonous Blood Weapons out of thin air, forming a dozen in a second, from swords, spears, rapiers, and naginata, while he ordered his group to ready any long-distance attack they had!

"Corrosive Waves! Blood Projectiles!" said Arthur, unleashing a concentrated wave of corrosive dark energy, coupled with a dozen of his own blood projectiles!

"Evil Eye, Blood Spear," said Jon, using his Evil Eye to immediately drain the life out of the boss slowly, while creating a large blood spear out of thin air, launching it at the bat's head!

"Black Thunder… Arrow Storm!" roared Timassa, infusing all the mana she had into her Skills and generating a dozen of black thunder arrows in a row!

"GRAAAAAARRR!" roared Adamantine, infusing all of her Dark Aura into her Dark Claws and unleashing a storm of dark slashing attacks!

"Phantom Fox Spirits! Blood Spears!" said Iris, generating Phantom Fox Spirits and Blood Spears, the Phantom Fox Spirits jumped over the Bat's skin, converting into tattoos that slowly made the bat lethargic, and then strong blood spears penetrated its flesh!

Noah and his subordinate attacks all fell over the Bat's back and head, slashing through its flesh and leaving deep wounds all around, Noah made sure to target the Boss' wings, slicing the membranes it used to fly so it could not generate storms again!

Clash! Clash! Clash! Clash!

"GGGRRROOOOWLL…!"

The Bat cried in agony as it quickly moved its body away, using its giant claws, raising them upwards and trying to slice Noah and his subordinates into pieces!

SLASH!

However, Noah managed to maneuver in time around the air, evading the powerful slashing attack and flying up into the air!

"T-That was close!" said Iris.

"So Noah-sama will carry us around now?" asked Timassa.

"There is no choice, it is safer in the sky now that the Bat cannot fly anymore," said Noah.

"Hehe, as long as I am at your side it's all good~!" said Iris adorably, as Noah sighed.

"GROWL!"

The Giant Black Bat Boss, however, had no time to wait for them to talk about a strategy, noticing the wounds on his wings, it quickly decided to simply employ other of its abilities, charging energy within its jaws, shadow energy!

"Shadows… on his jaws?!" asked Arthur.

"Right… we saw Bats use them before…" said Iris.

"Let's evade, for now, drink blood and recharge your Mana!" said Noah, flying around and evading the enormous beams of shadows released by the Giant Bat, breaking through the ceilings and making more boulders fall into the ground!

Boom! Boom! Boom!

Noah then realized something.

The boulders… were big.

And they were falling over the bat, a lot of them, in fact.

The Bat roared in pain, as it took away the rocks that fell over its body, although it had taken a lot of damage nonetheless!

The bat closed its jaws, seemingly resting from using its Mana, as it grabbed a giant boulder and pointed it at Noah!

FLASH!

The giant boulder was sent flying towards Noah!

Noah evaded by going down each time, but the Bat's precision was fairly good!

"What is this?! It's acting more like a monkey than a bat to me!" said Iris.

Clash! Clash! Clash!

The large boulders hit the ceilings and walls, generating more boulders to fall and more projectiles for it to fire!

Although it had its membranes gone, it still had the long fingers that bats possessed, and it used them to grab several boulders and fire them towards Noah!

Clash! Clash! Clash!

"What a troublesome bastard… Bare yourselves, I will be flying at a faster speed!" said Noah, darting around the air while evading the gigantic boulders, one by one barely reaching him, the enormous shockwaves they created generated loud tremors around the cave, as Noah kept evading, more boulders fell!

Until Noah reached above the bat's head, as the bat seemingly smiled, opening its jaws and charging its shadow beam!

BOOM!

Noah barely evaded, although half of his body was blasted off, he managed to save his subordinates by quickly moving them away with his blood tentacles!

"Nnghh…!" muttered Noah.

"Noah-sama! Y-Your arms… and part of your chest!" cried Iris.

"This is nothing," said Noah, covering his wounds with coagulated blood as the bones, flesh, arteries, and other things began to grow through it!

"Let's get out of here!" said Noah, flying away like a meteor from the current area as the bat did not wait for him to recover, firing more shadow beams every time!

Boom! Boom! Boom!

The ceiling began to quickly fall apart, larger rocks followed by enormous boulders!

Suddenly, the bat realized that it screwed up!

Noah smiled maliciously, he had done something incredibly simple, yet quite smart!

He abused the bat's shadow beam to break the ceiling until a big enough boulder were to fall over it!

"GRROOWL…!"

BOOM!

A boulder over three times the size of the bat fell over it, as its body was crushed into the ground, blood exploding out from the surroundings of the rock!

"Ah…! It buried itself!" said Iris.

"You simply used the environment to kill it!" said Arthur.

"Amazing, to be expected of our progenitor!" said Timassa.

"Stop celebrating you, idiots… It still alive!" said Noah, flying high into the ceiling as he saw the enormous boulder slowly cracking open!

CRASH!

The bat… was still alive!

However, its entire body was bruised, and several of its bones were broken, its jaw was barely not cracking open, and several of its long fingers were twisted horribly!

"It's on death's door!" said Arthur.

"Now, with all we got, kill it!" roared Noah, darting towards the dizzy Bat as he unleashed his Vampiric Eyes of Hypnosis, impacting the giant bat's movements for a few seconds, enough for a barrage of all kinds of attacks to fall over the Bat's entire body!

BOOM! BOOM! BOOM!

"GRYYYAARRR….!"

The bat cried in agony, as its entire body was pierced by enormous projectiles and electrify thunder, Noah flashed towards its head, as his claws grew bigger, and his blood exploded out of his body!

"Blood Sacrifice! Blood Armor!" roared Noah, covering himself with armor, resembling a scarlet knight, his enormous bloody claws penetrating the bat's neck, as the creature groaned in agony, he kept seeping his claws into the flesh, tearing it apart as he drank all of the blood coming out from the enormous wound!

"GROOOOOWL…!"

The Bat cried one last time, as Noah reached its spine, and cracked it open with his crimson claws, killing it on the spot!

CRASH!

Poof!

The gigantic body then turned into an enormous cloud of black smoke, quickly fading away as it left several Cores behind, shining brightly and greeting Noah's greedy crimson eyes.

"W-We did it…" said Arthur.

"Noah-sama did it!" said Iris.

"We helped too though!" said Timassa.

"Haahh…" sighed Noah, resting on the ground and dropping off his subordinates into the floor.

He noticed a few gleaming Cores within the pile… Ability Cores!

…And alongside that, other strange types of items.

"Oh! It dropped equipment too!" said Arthur.
