Villain: Ultimate Mutation System in the Alternate World

They had never abandoned their comrades, even after getting injuries that left them disabled.

But, they did not had any regrets, knowing they fought for the sake of humanity.

Cyntia\'s eyes filled with sadness after hearing Rudy\'s response, and she felt conflicted.

Rudy was a man of honor, commitment, and kindness—qualities that had drawn her to him in the first place.

But she needed him alive.

In a world already filled with heroes willing to die, what she truly needed was him by her side, alive and well.

"I\'m pregnant, Rudy. Please, let\'s escape this place! Do it for our future family," she pleaded, desperation evident in her voice as she grabbed Rudy\'s hand and placed it against her belly.

"Is this true, Cynthia?" he asked, his voice trembling with the sudden revelation.

"You can feel it, right? The heartbeat," she replied with a smile, her eyes shining with hope.

He focused his senses, and just as she said, he could feel a faint beating on her stomach.

It was undeniable—the rhythm of life pulsating beneath his touch.

One of Rudy\'s teammates, Bernard, witnessed the scene unfold.

Having been with the team for ten years, he was intimately familiar with Rudy and Cynthia\'s relationship.

In fact, he harbored feelings for Cynthia himself, though she had chosen Rudy over him.

"Buddy, I think we should escape. There\'s no point in fighting a losing battle," Bernard spoke up, his tone filled with concern.

"But..." Rudy began to protest, only to be cut off by Bernard.

"Do you really think you can change anything?" Bernard interjected, his voice tinged with frustration.

"Look at the reality of the situation. That demon is unstoppable. We can only hope that other cities send more powerful hunters." He explained, his words heavy with resignation.

Hearing the pleas of his friend and his girlfriend, he finally gave in.

With heavy hearts, the three of them turned and fled in a different direction, leaving behind the death and chaos .

But their decision set off a chain reaction, rippling through the ranks of the hunters and causing uncertainty and disarray among them.

Witnessing the strongest among them fleeing in fear, the remaining hunters followed suit, their resolve crumbling in the face of overwhelming terror.

Unfortunately, not all were fortunate enough to escape unscathed.

Some fell victim to Reign\'s long range attacks, their lives snuffed out by the deadly barrage of his projectiles.

Fortunately, Rudy\'s group managed to escape successfully, their quick feet enabling them to outpace others.

\'These things are annoying,\' Reign sneered in contempt as he tore another female hunter\'s body in half.

He glanced at the helicopters surrounding him in the sky, their gunfire kept echoing in his ears.

Unfortunately, The helicopters were flying higher than usual, so he had to think of way to get to them.

Then, a concept from his childhood fascination resurfaced in his mind.

It was something he had saw from an hundred year old anime series he had managed to obtain a copy of.

It was about a girl who could generate electricity and make a coin turn into a deadly weapon by incorporating the Rail Gun theory.

He became so fixated on the topic that he remembered researching the theory.

After looking into the rail gun theory, he discovered that what the girl did was impossible, even for someone with the ability to control electricity, due to numerous inconsistencies.

The Rail Gun theory was a concept rooted in electromagnetism and physics, particularly in the field of projectile propulsion.

Essentially, a rail gun utilizes electromagnetic forces to accelerate a projectile along a set of conductive rails.

In its simplest form, a rail gun consists of two parallel rails, typically made of conductive materials like copper or aluminum, with an electric current running through them.

A projectile, often a metal slug or projectile, was placed between these rails.

When the electric current was applied, it generates a magnetic field perpendicular to the rails.

According to the theory, the interaction between the magnetic field and the electric current creates a Lorentz force, which propels the projectile forward along the rails.

By increasing the current and optimizing the design, rail guns can achieve incredibly high velocities, making them capable of launching projectiles at hypersonic speeds.

With only human skin, it would have been impossible to accomplish all of this

But what about him?

With his lightning attribute and bones akin to metal with high conductivity, coupled with his genius mind, he felt a surge of inspiration.

All this time, he had been relying on the system for his skills.

However, he found the system\'s abilities to be too basic and straightforward. If he wanted to develop further and really become strong, he knew he had to think outside the box and create his own original skills.

As his mind raced, a blueprint appeared before him.

He exerted his control over his bones. His right arm began to transform, bones protruding from his arms and intertwining with each other in a complex pattern.

The bones in his arm elongated and fused together, forming a sleek and intricate structure reminiscent of a futuristic bio weapon.

Rib-like protrusions extended outward from the main barrel, creating a series of channels that seemed to pulse with dark energy.

Along the length of the rail gun, jagged edges and sharp ridges emerged, giving it a menacing appearance. Sparks of electricity danced along the surface of the bones, crackling with power.

At the tip, a cluster of very dense bone shards converged, forming a lethal projectile ready to be unleashed at his command.

[System: Congratulations, Host, for creating a new skill worthy of the System\'s acknowledgment.]

[Please name it for quicker access in the future]

Reign paused for a moment, recognizing the significance of naming his own skill. It felt like he had reached a new milestone.

"Death Rail-Gun," he responded.

[Death Rail-Gun - Saved]

After naming his skill, he refocused his gaze on his hand, which now looked incredibly awe-inspiring, leaving him fascinated by the transformation.

But Reign had no time to enjoy it, as the bombardment resumed once the smoke cleared, revealing his position again to the armies.

\'This guy doesn\'t know what\'s good for them,\' he chuckled to himself as he pointed his Rail Gun towards the sky, preparing to test it in actual combat right away.

Then, he summoned a Railgun slug, shaping it into a sleek, pointed projectile reminiscent of ammunition used in tanks for armor piercing.

Next, he infused dark red electricity into the rail-gun and into the slug.

The mechanism he had created for the Railgun activated.

BUZZZZZZZZZ!

The railgun emitted a sharp, high-pitched buzzing sound as it charged up, building anticipation for the impending release of the electrified slug.

"Death Rail Gun!"

What happened next unfolded too fast, as everyone could only catch a glimpse of a streak of red light before a helicopter went down out of nowhere.

"What was that?" A chill ran down everyone\'s spine after witnessing something that they could not comprehend .
