Vampire Overlord System in the Apocalypse

-----

Noah immediately evaded the Light Bullets, as he leaped into the air.

Big Sis specialized Magic Detection eyes quickly followed Noah, as she directed the bullets towards him with excellent precision, if it were not because Noah was enhancing his capabilities through his Skills, he would have already been reduced to pieces!

"Hm, you\'re good at running away, but can you fight back?" asked Big Sis, as she managed to get near Noah, using her large spider-like legs as blades and beginning to hit the ground, creating small tremors while trying to crush Noah or even impale him!

Noah\'s senses were enhanced to his limits, as he realized how frighteningly powerful was this Machine!

"This thing precision and Magic Detection make it even stronger than the Goblin Champion and the Shadow Lynxes, it makes most of my classmates seem like jokes… This machine was most likely contracted to fight and defeat monsters above Rank E or even D!" thought Noah.

"However, because it possesses high intelligence and decision-making capabilities, it might be even stronger… However, let\'s see how hard her shell is!" thought Noah, as he summoned his Blood Sphere and generated a large Blood Spear, throwing it at Big Sis\'s upper torso!

FLASH!

"Oh? Long Ranged Magic…" said Big Sis, as she directed the bullets towards the Blood Spear while being in midair, completely shattering it into pieces!

However, that was but a distraction, as Noah emerged behind her and grew his Blood Claws like slicing blades!

SLASH!

CLANK…!

"Oh?"

However, instead of doing a penetrative attack, Noah\'s claws only left a large scratch, but did not manage to get through the hard protection of Big Sis metallic shell!

"Fool, did you thought that my torso was weaker than my legs because it is smaller?" asked Big Sis, as her chest suddenly opened, revealing another shotgun!

"Die!" she said, firing several Light Bullets at the same time, blasting away Noah!

BOOM!

"Gaaahh…!"

Noah\'s chest burned through the Light Bullets, and exploded into pieces, as his body fell into the ground!

His chest was blown apart, only leaving a few pieces of flesh connecting it with the rest of his body!

A gigantic and burnt hole was the only thing left, as his heart and even lungs were turned into ashes!

"Sakura, make sure to dispose of his corpse-"

"Oh? Did you think I was dead?" asked Noah, as Big Sis suddenly opened her cybernetic eyes wide!

There, she saw Noah running towards her again, already reaching her upper body with his claws ready to slash her!

Where the giant hole was supposed to be, a large amount of coagulated blood was present, connecting his body together, and slowly regenerating the tissue lost, as she could even see a heart growing back!

"It took a lot of my blood reserve, but I guess I can also regrow lungs and a heart, who would have known?" laughed Noah, as he unleashed his Blood Soul, covering his claws with them and materializing them into larger claws!

"What kind of monster are you!?" asked Big Sis, as she pointed all of her shotguns towards and unleashed a barrage of Light Bullets!

Noah, however, unleashed a powerful slashing attack, making the Light Bullets explode before they could hit him, as he seeped his claws into Big Sis!

CLASH!

"Nggh…?!"

Noah Blood Claws seeped into the gigantic mech\'s small torso, breaking apart part of her shoulder, as one of her arms was blown off!

BOOM!

"You broke through my layered Magic Alloy Shell?! That… Should not be possible!" roared Big Sis, as she pointed her shotguns towards Noah, blowing him away in a barrage of Light Bullets!

Boom! Boom! Boom! Boom!

As the bullets penetrated Noah\'s body, Big Sis noticed how more blood was poured into his entire body, regenerating it even through midair!

"Are you immortal or something?!" she roared, pointing her claws towards him, and employing them as blades, trying to slice him into pieces!

Slash! Slash! Slash! Slash!

"Blood Manipulation!" roared Noah, as he saw his entire limb being sliced into pieces!

However, through Blood Manipulation, he manipulated the blood in each limb, including the blood inside the muscles and other parts, grabbing them and then forcefully sticking them back to his body!

Clash!

"T-That\'s ridiculous…!" roared Big Sis, as she pointed her shotguns at Noah.

However, she noticed a giant blade made of blood that had emerged from Noah\'s wounds, as he had employed his own blood and made a large blade with it!

"Through Blood Sacrifice, I spend my own blood to enhance my capabilities, and through Blood Retribution, the damage of my attacks is enhanced, this obviously includes my long-ranged ones!" thought Noah, smiling wickedly as he had no remorse on using his own body and pushing it to unimaginable levels so he could achieve victory!

The Blade was enhanced by Noah\'s Attribute Values, and by the damage, bonus added from Blood Sacrifice!

Noah has lost so much blood that the power it achieved was also double its original damage output!

Flash!

"W-Wait!" cried Sugar, as she saw the gigantic blade penetrate Big Sis torso!

CLASH!

"UNGGAAAKKHH…!" cried the giant war machine, as several of her circuits were being broken apart!

"You are quite valuable, but I had to do this!" laughed Noah, as Big Sis screamed and suddenly fell over the ground!

BOOM!

Noah fell into the floor like a ragdoll, he had somehow achieved victory against a giant machine capable of turning E-Rank monsters into ashes.

His body was barely regenerating now, and the speed it did had decreased exponentially as he had lost too much blood, and the one he had stored beforehand was all used.

Although Noah seemed \'immortal\' to others, he could not achieve this if he did not have fresh blood to drink and nourish his body with!

"Big sis!" cried Sakura and Sugar, as they ran towards her as fast as they could.

"Ugh… He actually… beat me…" muttered Big Sis.

"Don\'t worry, I will repair you in no time!" said Sugar, as her hands suddenly transformed into dozens of small mechanical arms possessing many types of repair tools.

"Let me take this out!" said Sakura, quickly taking away the large Blood Blade out of Big Sis\'s torso, throwing it away as it broke into pieces over the floor.

On the other side of the battlefield, Noah\'s party quickly ran towards him.

"Ah! Noah-sama, that was way too reckless!" said Iris.

"But I told you I would win, I don\'t fight-"

"We get, we get it! Heal!" said Arthur, as he employed his new healing Skill over Noah\'s body, managing to close his wounds with more ease.

"Here, drink this!" said Iris, as she poured fresh blood from her Blood Sphere over Noah\'s mouth, which he drank expressionlessly.

"N-Noah-sama, you didn\'t have to be so reckless…" said Timassa.

"Please… get well…" said Jon.

"You don\'t have to worry for me, I am your progenitor! Stop being crybabies," said Noah rather pridefully, although he seemed a bit happy that they worried about him.

After a few minutes, he felt anew, standing back up again.

"Now, \'Big Sis\', what do you think? Am I strong enough to be fitting of offering you a new life?" asked Noah.

"Y-You... are strong… Very well, I trust your strength… But what are your plans?" said, Big Sis.

"Seriously, you fight with him to almost death, but you didn\'t even ask him what he genuinely wanted beforehand? You really have some loose screws, Big Sis!" said Sugar.

"A-Ah… I might have gone a bit too fast… To be honest, I was angered that Sakura brought strange humans here, I was about to dispose of them, but when she tried to protect them, it really made me angry," said Big Sis.

"But I told you that they meant no harm!" said Sakura.

"I guess I should try to suppress my aggressive program a bit more… Although I seem to have calmed down now," said Big Sis.

"You really should! I can\'t believe it, you\'re so reckless!" said Sugar.

"I guess they are not so different than us…" said Iris with a bitter smile.

"Now that I have your attention, what I have come to offer you is to join our guild," said Noah.

"Guild…?" asked Big Sis.

"Here we go…" sighed Arthur.
