Vampire Overlord System in the Apocalypse

-----

Within a faraway Sector, over a tall skyscraper building that represented one of the biggest corporations that had raised after the Apocalypse, a young man with long blonde hair and shining aquamarine eyes glanced at a holographic window.

As usual, he would be designing new types of mechanical items or body parts, improving structures through the use of advanced magic technology and his knowledge and mastery over it gifted to him by his awakened Ability.

He was no other than the director of Axis Corporations, the one who started it all, the owner of the wealthiest and most known corporation in the entire world after the Apocalypse.

It was all… thanks to the power he was gifted after awakening that he was able to accomplish so many things.

However, his fervent resolve always made him strive forward to higher and newer horizons, although he was often caged inside of his office designing new things, he was in fact a famous S-Rank Hunter.

His daily routine, however, was to design new types of mechanical constructions, improve parts, and more.

Although his creations were always thought to be masterpieces by the public, he always strived forward to improve them even further. He was never satiated with the greatness of his creations, and always found ways to improve them.

As the creator of every machine, even if they were produced in mass through the special machines he created and distributed around the world to create and design even more machines, he still had an innate connection to all of his creations.

He knew that many became scrapped metal, others that became failures and escaped to suburbs, and a few others that had tried to rebel against his commands.

He saw these as flawed, and quickly cut his connection with them, leaving them to do whatever they wanted, to die or not, he did not care.

For him, they were simply failed creations that he could take notes from to improve into his new designs.

However, he had forgotten to cut the connections with two models amongst the hundreds of thousands there were, which he had not thought would strive from their original functions so much.

Due to his superhuman capabilities and special Skills, his mind was like that of thousands of computers, he was able to administrate every single of his creations, although he held no direct power over them, he was able to see what they were doing to an extent, even how they felt or how their models were.

Amongst these many models, a certain group of them had… recently became strange.

Only about a week and a few days had gone by since that time, but he still could remember what they had become right before cutting their connection with him.

Their glowing, blue-colored signals suddenly became crimson red, and their mechanical properties changed and evolved through a strange type of magic and powers infused within them… something that, through his entire life, he had never seen.

Since everything started that he never found anyone capable of "hacking" into his own creations like this.

He was left speechless.

He, an S-Rank Hunter, had his own creations hacked and changed.

Even… he felt like they were improved by this strange power.

He felt both intrigued and scared afterward.

He felt scared due to someone being able to take over his creations, improve them, and make them powerful enough for them to completely cut their connections with him.

And intrigued about who this mysterious person was, what did he do, what kind of ability he used, and if he could be willing to work for him.

Throughout his long life, he has never found anyone with similar powers to him.

Someone who could be capable of influencing his creations and… improve them.

From the little time he had before his creations lost their connection with him, he learned a few things from their improvements, things that he had never thought possible within his powers, many of such abilities which he had tried to create many times, but never working.

One of such abilities was that… the Mana Core Batteries became self-sustainable.

Usually, any mech he created needed to change their Mana Core Battery every so often, they were batteries after all, and could not be easily recharged, if overused, they would even break.

This was something he could not do anything about, as long as his creations were fueled by his mana, it would be fine, but to make them independent and go around the world, these batteries were needed, which he could not design and were rather away from his power.

These batteries were created by the combined effort of many alchemists and high-tech mechanical weapons he also created.

But he had already reached the limits of what he could do about it, however, these robots who changed their mana core batteries were different, such mana cores had become crimson red, and gained immense magical capabilities.

Amongst them, they gained the ability to absorb mana from materials and improve themselves!

Not only that, as there was another similar ability, the power to self-replicate pieces of their own bodies, design new ones, and completely adjust their own bodies through the accumulation of mana!

This was something that he could partially do on his own creations that were always at his side when he fought, such as the enormous mechs he piloted, however, any other independent creation lacked such properties, and even those he used for himself were very limited, not to this point of nanomachine-like shapeshifting ability!

And this was not all.

The creations were able to assimilate magic materials and fuse their own components with them! This was honestly ridiculous.

Not even him could do this as smoothly as these robots!

And… as if things were not ridiculous enough, they gained some kind of magic mass that resembled… a primitive soul!

Through this soul, these robots even acquired some kind of affinity, and were able to even develop and use abilities they developed!

Skills and Magic!

This was something his machinery could not develop.

He had to arduous create armament, weapons, and cannons fueled with magic, but to use innate Skill-like Abilities right off the bat… was nothing but insane for him!

He, the owner of Axis Corporations, had finally found someone that complemented his abilities, someone that was worthy of becoming his companion as both walked through the path of machinery creation and the bright future of magic technology!

If he wanted to bring back the old world and heal the contamination of Earth, he needed this mysterious person at his side!

He was willing to do anything… even if he had to force him to cooperate!

Even if he had to slave him or something, his powers would be his!

He smiled wickedly, feeling fascinated by the possibilities.

And since then, he had left the supercomputers within his building searching for the location of these robots.

After many days, they finally found it…

"Sector D… I see! So that is where you are… I shall go there immediately, and seek for you, my friend! You and I shall seek the bright future ahead of us! And if you do not cooperate… well, I have more than a thousand ways to force you to…" said the man smiling with resolve and wickedness.
