Villain: Ultimate Mutation System in the Alternate World

As she lunged forward, her forceful step left a clear mark on the floor.

She gripped the hilt of her sword tightly, and it emitted a low, buzzing hum as it effortlessly sliced through the air.

With a craze expression, she unleashed a powerful horizontal slash coming from her right, the blade cutting through the air aimed directly at Reign's midsection.

However —

Before it could connect, she smoothly transitioned into a vertical strike by forcing the trajectory to shift to trick Reign, bringing the blade down in a powerful overhead chop.

Reign saw this and was ready to block it .

But, with a quick twist of her wrist, she change the direction again of the sword to a horizontal slash , this time coming from her left, aiming for Reign's side.

This attack was a double feint, a maneuver made possible by her precise control over her body, augmented by the Power-suit.

Her caliber surpassed even that of a Gold Rank Member of the Veiled Nights, showcasing the extent of her skill and power.

CLANG!

Reign blocked the attack with his single-handed dagger.

While her move might have confused others, he saw through it almost instantly.

Compared to Arc's Thunder Slash, her attack was as slow as a snail's pace.

"You're annoying, Brother!" she clicked her tongue in annoyance.

She knew that kind of attack would not be enough to kill Reign, but she was still shocked to see how easily he parried it.

After performing a double backflip to create some distance, they now faced each other toe to toe.

'Interesting. Are Divergents immune to viruses' he pondered.

He had used his Silent Killer on her, but it hadn't worked.

It means that she either has a very strong anti-bodies due to her Divergent DNA or the possibility that she had taken some form of enhancement to bolster her immunity further.

"I'll give you credit, Brother. Blocking my attack this easy show that you're really strong," she chuckled. "But now, I'm getting serious. I hope you don't lose too quickly," she declared.

With a click, her sword began to dismantle until only a thin blade remained, resembling those used by hunters but shorter.

"Don't be surprised. I'm actually a speed type, and I just use that big sword because I want to enjoy my fight," she giggled sadistically, licking the blade with her tongue.

"You talk too much for someone so weak," Reign shook his head in disappointment .

The crazed girl, her ego bruised, failed control her emotion and began her attack.

SWOOOOSH!

She was much faster than before, her agility showing wonders as she zigzagged around her target, trying to confuse him.

He, on the other hand, remained unfazed. He didn't even have to turn his head because he could sense everything around him, and his peripheral vision was wide enough to detect any movements.

As she darted around, her movements looked erratic, but there was a calculated pattern to them.

SWOOOOSH!

With a quick motion, she exploited a brief opening in his defense and launched herself to him.

At first, it looked like she was attacking him head-on, but suddenly, her sword changed direction, aiming at Aiku's head.

Unfortunately for her , Reign's reaction was just too fast as he intercepted her blade, preventing it from reaching Aiku by mere inches.

But this was something she had anticipated. The moment he blocked her initial attack, the blade slid upward, directly aimed for his throat.

'Another trick again,' he sighed.

CLANG!

He blocked the attack, his movements devoid of any wasteful movements. Despite her attempts to overwhelm him with speed and tricks, he remained composed, deflecting each attack with ease.

CLANG!

CLANG!

CLANG!

Each swing grew faster, more diverse, and much faster

She was a Divergent with a unique ability that fueled her power the more she moved. She was banking on this to overpower Reign in the long run.

Normally, such a tactic might work for her, but the power gap between them was too vast.

He operated on a completely different level. Even if he allowed her to swing her swords for hours, there was no way she could contend with him.

In fact, Arc, when he was still alive, had posed a far greater challenge, and Reign had managed to defeat him even before reaching his current level.

As the fight progressed, Aiku was stunned to witness the vast power gap between the crazy girl and her master.

She could see the intense focus and effort in the girl's expression, putting everything she had into each attack.

Each clash created shock-waves, but he barely moved his dagger, effortlessly blocking each strike.

"You're annoying me !" With a frustrated scream, the girl swung her weapon with all her might, aiming for Reign's vulnerable spot.

But just before her strike could find its mark, a sudden feeling of weakness washed over her, causing her to falter and drop to her knees.

THUD!

Gasping for air, she clutched her chest, her heart pounding erratically.

'Oh it's finally working, '

As he watched her writhe in pain, Reign couldn't help but smirk inwardly.

His plan had worked. By subtly injecting her with the Silent Killer virus through small needle-like bone projectiles, he had slowly infected her without her even realizing it.

The adrenaline of battle had masked the sensation of the tiny mosquito bites size injections, allowing the virus to spread unnoticed until it finally took effect.

But it wasn't all good news.

This experiment also revealed just how strong the immunity of Divergents were.

Most of his virus had died out from her antibodies alone, and he had to keep attacking her until to kept on pumping more virus in her system.

"W— What's happening to me?" she groaned in pain.

Reign stepped closer, his expression unreadable. "It's your body finally reacting to my Silent Killer. Took you long enough."

Her eyes widened in realization

"You...poisoned me?" She tried to stand, but her legs gave out beneath her.

Reign shrugged. "You should've paid more attention. I was just testing my skills on you,"

"You…" She gritted her teeth in anger. Then her vision blurred, and her strength faded rapidly. "This...isn't...over..." she gasped, collapsing to the ground

"Amazing, she's still alive even after all of that?" he mused aloud.

"Alright, time to kill you," he knell down and was going in for the kill but Aiku spoke from behind him.

"Don't kill her, Master!" she pleaded.

"Why?" he asked.

"I want her body. I told you my power depends on my host, right? If I take over her body after I'm done using my current host, I could gain her power," she explained.

Reign considered this for a moment, his eyes narrowing as he assessed the crazy girl who was unconscious on the ground.

"But she's too weak and her face annoyed me" he replied.

"It's okay, it's still better than my current one," Aiku explained.

She realized that despite all her authority, she was still useless against pure and raw power.

If not for Reign protecting her, she would have already died dozens times over.

"Alright," he nodded.

If Aiku could transfer from body to body, it meant her usefulness to him could be extended.

With this in mind, he moved his hand to grab the crazy girl, but before he could do that, he sensed the presence of multiple people closing in on him.

'This guys never learn,'
