Villain: Ultimate Mutation System in the Alternate World

"Did you really think you could go on living after crossing me?" he sneered, his voice dripping with disdain.

She shrank further into the bedding, trying to make herself as small as possible beneath his towering figure.

The grin on his face widened as he watched her struggle.

"P— Please, forgive me. I didn't know you were a demon lord," she pleaded, her voice breaking with desperation.

"I can't do that," he said, shaking his head. "I enjoy watching you suffer," he continued, leaning in so his face was inches from hers.

"I want to hurt you more, torture you, and destroy you. And after you're dead, I'll eat you like livestock—no, you'll experience worse than that." His words cut deeply, each one delivering a new wave of pain.

She recoiled, her breath coming in short, panicked gasps.

"I wonder how this frail thing tastes," he said, grabbing her thin arm and pretending to bite it.

She wanted to scream, but every time she tried, Reign slapped her brutally, silencing her cries with each harsh blow.

"The next time you scream, I'll rip your head off and shove it in your hole," he threatened.

Emy's face contorted in horror and despair, tears streaming down her cheeks as she tried to grasp the reality of his threat.

She knew he could actually do what he had just said, making the situation even more horrifying.

"P— Please don't kill me. I'm sorry for everything. I can give anything. My father is the general in this city. If you let me go—" she pleaded, but before she could finish, he slapped her again.

"I told you to stop making noise, didn't I? Why can't you just listen for once?" he added .

This time, he didn't stop. He kept hitting her, his hand striking her face over and over.

SLAP!

SLAP!

SLAP!

Her head jerked with each blow, tears mixing with blood as he held her hair, forcing her to endure.

Emy's cries became weaker with each hit, the pain and terror overwhelming her.

Her eyes, once wide with terror, were now half-closed and glazed over, the whites barely visible behind swollen lids.

The repetitive slaps had also left her face bruised and puffy, with blood seeping from the corners of her mouth.

"Why are you not talking anymore? Did you bite your tongue?" Reign's cruel laughter echoed in her ears, making the nightmare feel endless.

She tried to speak, but her face was too badly beaten to form words.

"You can't talk ?" he asked, but all he received were groans.

"Since you're not planning to speak, then you don't need these," he said with a sadistic chuckle.

He grabbed one of her front tooth and yanked it out, blood spurting out immediately.

"Nuh..Stuhhp…" She squirmed in agony, but he wasn't finished yet.

With a cruel smile, he yanked out the next tooth.

"That's another one," he said, his voice dripping with satisfaction.

Blood spurted from the socket, and her body convulsed as she let out a muffled groan.

He moved to the next tooth, twisting and pulling until it came loose with a sickening snap.

Next, he held it up, looking at it briefly before popping it into his mouth like a candy.

Chewing slowly, he savored the crunch with a twisted sense of satisfaction.

"That's three," he declared, his eyes gleaming with excitement.

The process continued, each tooth pulled with cruelty in mind.

Blood flowed freely, mixing with her tears and sweat as her suffering intensified.

Meanwhile, Reign took his time, not rushing but enjoying the torment. He counted each tooth aloud as he removed them, turning her suffering into a sick game.

"Ten," he said, with a creepy smile, as another tooth came free. He chewed it again, letting the taste linger before continuing.

By the time he reached the last few teeth, she was barely conscious.

Her skin was slick with sweat and blood, her lips trembling as they parted in a silent, broken plea.

Finally, as he pulled the last tooth, he leaned back, admiring his work.

She no longer had any teeth, and her face was a horrific mess. It was a miracle she was still alive.

"You can't die yet," he said, shaking his head.

He then injected her with a non-transmissible virus.

An intense burning sensation spread across her skin, while her throat dried out so severely that she couldn't scream.

The symptoms were excruciating but not fatal.

And to prolong her suffering, he had included a pathogen that would increase her pain sensitivity while preventing her from bleeding to death.

Her face twisted in sheer agony, her eyes wide with terror and pain.

Her once smooth and pale skin now cracked and reddened, as if it were being consumed by invisible flames.

Every nerve in her body screamed as the burning sensation grew more intense with each passing second.

Tears streamed down her cheeks, mingling with the snot from her nose, creating a pitiful and messy display of her suffering.

Meanwhile, Reign watched with a cold, sadistic look, his eyes fixed on her.

Her face showed her deep misery and desperation, showing just how much pain and suffering she was feeling.

Finally, after enduring so much , her heart gave out. She went into cardiac arrest, and in her final moments, all she felt was fear, regret, and horror.

But even in that moments, Reign didn't grant her a normal death. He opened his mouth wide and began to devour her.

Bones and muscles cracked loudly in his mouth as he tore into her flesh.

Each bite was accompanied by sickening sounds of gnawing and crunching.

As he continued to devour her, he felt a strange and unfamiliar sensation growing inside him.

It was as if something new was awakening within him, but he couldn't quite pinpoint what it was.

The feeling was different from anything he had experienced before—intense.

His mind became clouded, focused solely on the intense pleasure of consuming her.

Until—

[DING!]

[HIDDEN MISSION -TITLE QUEST- COMPLETED]

[REWARD: TITLE]

<VENGEANCE >

[VENGEFUL AURA: This skill creates an intense feeling of anger. When activated, it makes host stronger and faster in fights, especially against targets host really hates.]

"What? I didn't know something like this actually existed," he exclaimed, taken aback by the unexpected surprise.

He read the description of the new title, and with each line, his grin grew wider.

The title's effects were stackable, and although the system hadn't specified the requirements, he was certain it was closely tied to his own state of mind.

'So once again, I'm being rewarded for being cruel and acting on my impulses,' he thought to himself.

He had suspected this before, but the new system feature confirmed his theory.

'Well, I don't really mind the additional benefits,' he added.

If it were before, he would have been hyped up, but now he couldn't help but be wary of the system.
