Vampire Overlord System in the Apocalypse

-----

Within the residence of the Crystal Family, the notice of Emerald's presumed death impacted the family greatly.

Although they had never expected their son to truly die due to his talents, and would always believe that he could be surviving somewhere else, Emerald's father, Granite Crystal, knew that this was… the truth.

It was all thanks to the special accessory he possessed, which connected to his son's vitality signals, something rather normal for rich aristocratic families to give to their young Hunter children.

Emerald was a young man filled with talents and great Skills, and he was always at the side of his friend, so Granite could have never expected his son to suddenly be murdered…

Even more, because he did not know about the schemes and plans of the government within the military school, who planned to filter the strongest students and incentive them to kill each other without the consent of their parents for such barbaric acts.

Especially because they wanted to seek a new batch of Soldiers, which the government of Sector D was trying to amass for the imminent war that was approaching against Sector B for resources and territory, as Sector D and Sector B have been battling against each other for the ownership of a large area within the wastelands whose deep and dark caves were filled with valuable Magic Crystals of high qualities, something that was usually very rare within Earth, as most Magic Crystals were harvested from Dungeons, and after C-Rank, Dungeons would become too dangerous to safely harvest them.

However, Magic Crystals from higher Ranks, even up to A-Rank had been seen and extracted from these underground mines, which both Sectors wanted for themselves to increase their resources, profit, and more.

Although Granite was aware of this dispute, he did not know that such a Military School was so involved with it to the point that the government would do something so ruthless as incentivizing hate and fights to filter suitable and strong soldiers for them…

However, through his insiders, he managed to learn an important piece of information…

"They saw Emerald enter the same cave as the group of a student named Noah… after the incident, they saw Noah and his group walk out… but Emerald… did not come back… and not even his corpse was… left behind…" muttered Granite, remembering the bitterness of such a thought.

The beloved son he had taught so many things, which he had trained and made stronger through these years, and who he had helped develop his unique ability to this point was now… killed by a nobody… who somehow did not even leave his corpse…

It was very obvious why Noah would not leave the corpse there, as it would be more than obvious evidence of the act, so he had saved it alongside the other members of the party inside of the Dimensional Storage Ring, and had cleaned all the blood around through Blood Control, leaving nothing behind to be used as a clue…

"Noah… This damn brat… I cannot believe that my… that my Emerald… my boy… would die to this piece of trash! He must have used some… underhanded method to kill my precious son! I cannot… let such a filthy street rat do such an offense to my family… Killing my precious son will only lead to his death! I cannot… bear with the pain of my heart… I need his head below my feet, I want his head at all costs...! I will not rest until… he is exterminated! Servants!" said Granite, as he called upon two butlers.

"Yes, Granite-sama," they said at the same time.

"Call my children… There will be a meeting… We shall discuss… the extermination of Noah and all those related to him! We will not rest until we avenge Emerald!" said Granite, as the two butlers who resembled more as ninjas darted out of the room while nodding.

Flash, flash!

Granite's eyes were filled with sorrow, as he glanced through the window into the bright and futuristic city of Sector D… the death of a son to a father could be said to be the most painful thing to ever happen to them, simply thinking about his son would bring him terrible pain on his heart, as if he was running out of air.

He sat down on his chair, as the man glanced at the photos of his son, remembering all the times he used to be with him, teaching him, guiding him, laughing with him at his side.

Granite was so proud of his son, so much as he was the only thing that his wife had left after she died out of an incurable disease within this new apocalyptic world, a disease that often affected people older than 30 years of age, named Mana Cancer.

Mana Cancer was provoked when the cells of a person could not properly adapt to the contaminated and high-density Mana flowing through Earth, although some would still awaken Skills, the Mana Cancer would continue to slowly eat the person's from the inside out, their cells would begin to mutate and degenerate, as the person would slowly turn more… monstrous as if it were becoming a Mutated Beast.

However, unlike Mutated Beast, the person would not be able to bear with the mutations and would die out quickly after if not well treated…

Granite could still remember the death of his wife as if it were yesterday, and how he had left Emerald for him to take care of alongside the rest of his siblings…

She was a good mother who had many children, and Emerald was the last one.

Granite had met her when the Apocalypse had still not stabilized, and everything was still chaotic when humanity was still fighting for survival…

The man began to cry desperately, his sorrow was so big that his proud face resembled that of a pathetic man who had lost his soul…

However, his children were soon to come, although Emerald was the youngest and brightest, he still loved each one of them… And wanted to ask them the favor to exterminate Noah and anyone at his side, just to teach him what was to suffer the same things as him.

Quickly after, all four of his children had gathered in the same room as Granite.

"Father… So Emerald… No… It can't… it can't be…" cried a petite woman in her early twenties, with short red hair and green eyes, wearing a beautiful crimson dress, she was Ruby, the third daughter of Granite Crystal, a C-Rank Mage-type Hunter.

"Who… Who could… have done such a thing… Emerald was so strong… he was destined to be at… our side soon enough! You shouldn't have let him go to that damned School…" muttered a young and slender man in his early-twenties, with short blue hair and iridescent green eyes, Sapphire, the first son of Granite Crystal, a C-Rank Archer-type Hunter.

"Emerald… No, Sapphire, this is not the father's fault. This is our fault. We should have been more attentive to him, more protective… The weight of his death… falls upon our shoulders to bear…" sighed a beautiful young woman in her mid-twenties with long green hair and glowing rainbow eyes, Agate, the second daughter of Granite Crystal, a C-Rank Warrior-type Hunter.

"I understand why you called us here… father… I can… barely bear in my mind that our little Emerald is now… completely gone… Leave it to us… We will make sure to show that trash… what hell truly is… we will make sure that… he will suffer the most painful of deaths…" said a startling beauty with long golden-brown hair and yellow-gold eyes, her figure was slender and beautiful, with wide hips and large breasts, she was Amber, the first daughter of Granite Crystal, a B-Rank Mage-type Hunter.

Granite noticed as his four children unleashed enormous magical auras from within them, they were enraged… incredibly enraged and filled with sorrow…

They could barely resist their sorrow and wrath, they needed to avenge their little brother, the one that had brought so much happiness to their lives, the one they loved so much… the one they were so proud of…

They needed to exert revenge…

To tear apart the one that did this to their brother!

To break his spirit…

To make him go through complete hell! action

To make him understand the pain they had gone through!

They would not rest until… they were to completely tear his entire body not pieces and then burn it into ashes as he screamed in agony!

This was the only way…

They could not do anything else.

They could not bring the dead back to life…

There was only… the option of appeasing their wrath.

Granite dropped some documents and pictures over the table, showing Noah and his party.

"There are their names and information… Noah, Iris, Adamantine, Jon, Arthur, and Timassa… What a pity, Arthur might have been from a family which was a bit respected, but nothing I would even care about anymore! If he dared to kill or help to kill my son… I do not care what his position is! The Strongarm family is not near as strong as ours… Bring me his head alongside Noah's!" said Granite, his face beginning to disfigure as he showed a monstrous and wrathful expression on his face! He was filled with bitterness, with anger, with sorrow!

His children could not help but think the same, they wanted to appease their wrath, sorrow, and bitterness, they were frustrated about their own mistakes, and about how it brought Emerald's end…

"Yes, father!" said the four Crystals, their bloodlust emerging like a vicious beast!

…However, they did not know that the one they wanted to show hell had already gone through it, and had been reborn as something they would never comprehend.
