Villain: Ultimate Mutation System in the Alternate World

"Well, that was unsatisfying," he grumbled, his disappointment evident in his voice.

Absorbing the corpses of the dead guards did little to satisfy him. It was clear that this meager numbers was far from enough to fill him.

But it was alright because from here on out he could go and kill everyone inside this mansion.

Cyril likely believed that he would only target her family members and spare the innocent individuals who were merely working here and trying to make ends meet.

Little did she realize that she had struck a deal with the devil himself.

Reign had no intention of letting anyone escape tonight, not even the kindest soul in the world.

In his eyes, all humans who were not useful to him were nothing more than food.

But before starting his one-sided massacre, Reign needed to take care of something first.

CRACK !

His bones began to crack and expand, reverting to his original size.

'Yeah, this size still feels better,' he chuckled to himself, relishing the sense of comfort that came with his original form.

Contrary to common belief, turning smaller didn't mean he was lighter. When he compressed his bones, he became much heavier.

And it wasn't merely a matter of doubling his weight; the increase was far more bigger than that.

The only reason the ventilation and ceiling could support him was because he was good at shifting his weight using Stream Guide.

Since reaching the Upper Rank, his control over Stream Guide had improved significantly, becoming almost second nature to him.

If Ben were alive and here right now, he'd be cursing aloud about how unfair the world was.

Seriously? he spent years honing his skills, and Reign just copied and surpassed him.

It felt like a scene straight out of a shonen anime, where the protagonist defeats the villain who had trained tirelessly for years, all thanks to the power of friendship.

'Time to hunt,' Reign's expression twisted into a sadistic grin as imagined the number of humans that would die in his hands tonight.

With a powerful first step, his legs coiled like springs as he lunged forward on all fours to maximize his speed, the sheer force of his movement creating a gust of wind that rippled through the air.

SWOOOOSH!

SWOOOOSH!

SWOOOOSH!

The guards stationed at the garage turned their head at the whooshing sound to investigate.

But before they could process what was happening, a breeze swept past them, severing their heads instantly.

THUD!

It all happened so quickly that no one had a chance to make a sound.

Their heads were dicapitated, tumbling across the cold floor as blood spurted from their sliced necks like fountains, painting the floor red.

Having cleared the garage , Reign used the stairs leading to the first floor of the mansion, continuing his deadly rampage.

He showed no mercy to anyone he encountered, whether male or female, guard, maid, gardener, or butler.

Anyone unfortunate enough to cross his path met their maker, their heads severed before they could even feel anything.

As he entered a room filled with maids enjoying their meal, Reign faced another challenge.

With too many people to confront directly, he adjusted his approach.

Instead of slashing his way through, he aimed both hands and launched a Claw barrage, in attempt to kill everybody in one attack.

Those who were supposed to be taking a break suddenly felt a cold sensation wash over their bodies.

In the next moment, they were riddled with small holes, their bodies collapsing to the ground dead and bleeding.

When Reign finished with one area, he didn't stop to rest and went to the second floor.

He continued to hunt down anyone inside the house, moving nonstop, not giving anyone enough time to even raise an alarm.

The once well-decorated walls and expensive carpets were now stained with blood and littered with corpses.

It was a one-sided massacre, a display of power that emphasized how Reign's capabilities had far surpassed the normal standard for demons.

One by one, many more fell to Reign's deadly attacks until only those in the dining room remained.

Oblivious to the deaths unfolding around them, they continued to eat and discuss business, unaware that their mansion had been transformed into a hunting ground.

"What's this?" One of the butlers spoke up as he noticed a crimson liquid flowing from the gap beneath the wooden door.

He raised his eyebrows, assuming someone had spilled a glass of red wine.

Curious, he knelt down to inspect the liquid more closely,

BAM!

The wooden door shattered open, and before the butler could react, Reign's claw grabbed him, crushing his face like a watermelon.

"Demon!" Cyril's family exclaimed in unison as they laid eyes on Reign's terrifying and imposing skull face.

"Protect the President!" Two guards stationed at the corner rushed forward, their fast movements revealing their status as Divergents.

"Fuck off," Reign retorted coldly, activating his Death Aura.

Instantly, the room was enveloped in an oppressive atmosphere, causing everyone present to feel their bodies suffocating under the intense pressure.

The two guards momentarily staggered and stop moving.

It was a dumb mistake.

In the next instant, two projectiles pierced their heads directly, leaving them stumbling lifelessly to the ground.

"No!!!!!" The women at the table began to cry hysterically after witnessing the brutal attack.

"I said, fuck off," Reign's cold voice echoed again, his gaze fixing on one of Cyril's brother who was attempting to use his phone to call for help.

'Idiot,' Reign muttered, shaking his head in disappointment. Clearly, someone couldn't read the room.

A hole appeared in his forehead as he was shot dead doing something unnecessary .

"Let's not be hasty here. Anyone attempting to call for help will be shot indiscriminately," Reign warned.

"I'm impartial to gender, so don't test my limits." He added, his gazed scanning the women in the room.

Reign's cold tone, coupled with his imposing aura, compelled everyone to instinctively obey his words.

"A demon that can talk? A High Rank Demon?" Cyril's father spoke, his voice tinged with unease.

As someone of wealth and influence, he had access to real information, and he understood that the ability to articulate speech so fluently was a trait typically reserved for demons of at least High Rank.

"A High Rank?" Reign chuckled, unable to believe he felt slightly insulted by being referred to as such.

Well, in all fairness, these people were so weak that he hadn't even needed to go all out.

Cyril's father saw an opportunity.

An intelligent demon presented a chance for negotiation. Whoever had hired such a powerful entity must be one of his competitors or someone who hated him, willing to expend considerable resources to gain a favor of a powerful demon.

"Who did I offend?" he asked, his mind racing to identify the potential enemy behind this calculated move.

Little did he know, the mastermind behind all of this was none other than his own daughter.

"Offend?" Reign chuckled as he settled into the same seat once occupied by Cyril.

"A demon of your caliber wouldn't target my family without reason. Tell me, who did I offend, and how much were you offered?" he asked, mustering his strength despite the oppressive aura enveloping him.

Even Cyril's step sister who was acting smug and bitchy before was now silent, she was trembling from head to toe, and had already peed her panties because Reign was sitting next to her among all people.

"I'm afraid your offer can't compete with what my employer has on the table," Reign shook his head with a hint of amusement before casually lifting a glass of wine to his lips and taking a sip.
