Villain: Ultimate Mutation System in the Alternate World

'Should I do it? Should I just fly straight in and start destroying things?'

The idea crossed his mind, and he loved it. The chaos, the panic—it would be entertaining.

But then again, that would be helping Lilith too much, and that didn't sit well with him either.

'No,'

The best scenario was something far more satisfying. He'd go to the front lines, play the part of a devoted angel, and wait.

Then, when the time was ripe, he'd reveal himself in full, and making her regret ever betraying him.

'That's right. Revenge is best served cold. A little patience won't kill me.'

His lips curled into a smirk. 'It's not like they're going anywhere.'

On the streets, they continued walking until they reached what looked like a road made of sparkling dust. He noticed that most angels stuck to its path.

It maintained order, and he could also sense restrictions in areas that were not meant to be fly zones.

The armed warriors suddenly stopped. One gestured toward the sky.

"From here, we fly."

The restriction was lifted.

Around him, the others took off, ascending toward their destination.

As he followed, the city stretched beneath him, revealing its full grandeur.

Towering structures gleamed under the eternal light, their golden surfaces reflecting a brilliance that almost hurt to look at.

Temples and sanctuaries lined the streets. He also spotted floating platforms where groups of angels gathered, their glowing wings casting soft halos around them.

Further below, smaller structures stood in neat rows—homes, perhaps.

Though they were nothing compared to the extravagant temples, they still bore the same pristine architecture, as if even the most basic dwelling had to uphold Heaven's image of perfection.

Despite the overwhelming beauty, something felt off. It was too flawless, too controlled.

Eventually, their path led them to a sprawling mansion nestled within the city's core.

Unlike the rest of Heaven's structures, this one was built on a grander scale, its polished gold and ivory walls stretching far and wide.

THUD!

He landed with the others, his gaze sweeping over the elegant architecture.

White marble walls, gold-trimmed pillars, intricate carvings woven into the surface—it resembled a palace more than anything

Nearby, he overheard whispers from passing angels.

"The Seraphic Legion"

Reign's brow twitched as he continued to listen. The angels ahead spoke in hushed voices, their tones reverent and oddly careful.

"So, this is that place...." one of them murmured. "Where Heaven's finest warriors reside."

One of the angels muttered, "Yes, normally we're not allowed here, so I don't know why we got summoned."

SWOOOOSH!

A sudden gust of wind tore through the courtyard, scattering dust into the air. Shadows shifted overhead, and in an instant, all whispers fell silent.

Six wings spread wide as the angel hovered above them, its presence so overwhelming that the others instinctively looked down.

Its large wings, layered like a storm of feathers, moved slightly as it looked down at them.

"We give respect to Seraphim Melissa," they declared in unison before bowing.

Reign observed their movements and quickly followed suit, lowering his head just enough to blend in.

However, contrary to the amazement of the others, he found the newcomer rather lackluster.

'This one is weaker than Ariel, so there's no way the presence I sensed came from her,'

"You! What are you looking at?" Melissa called out.

"I apologize," Reign said, bowing his head deeper.

He had no issue acting this way because it would be much funnier when he blindsided her later.

Just imagining the look on her face was enough to keep him calm.

'Not good. I need to stop thinking about such fun stuff, or I won't be able to hide my grin,' he reminded himself.

The Seraphim didn't waste any more time on him, turning her attention to everyone.

She hovered slightly higher, her six wings stretching outward as if to remind them of her status.

"You stand here today because Heaven demands more from its warriors," she began.

"We are meant to be the unshakable force, the protectors of divine order. Yet, even with all our strength, cracks have begun to form."

A pause. Her golden eyes swept over the group, searching for any sign of weakness.

"You know that most of our angels are on the front lines, fighting the devils. Because of this, our numbers are decreasing at an alarming rate."

The others didn't like where this was going. Some already had a clue about what would come next, their expressions tightening as if bracing for bad news.

"Rejoice," she announced, "You… fine warriors would normally not qualify to take the advancement test. But now, you have all been given the chance to prove yourselves."

Everyone stiffened, knowing full well that in a war, "advancing" meant being sent to the front lines to die.

Meanwhile, Reign found himself intrigued by this so-called Advancement Test.

He glanced around, noting the unease in their faces.

Though hesitation was clear in their stiff postures and clenched fists, none dared to voice their concerns.

"Good. I'm glad that all of you are willing to help our cause,"

Melissa nodded, like a proud teacher praising obedient students—as if she had given them a choice in the first place.

As expected, angels were a bunch of hypocrites. And it seemed the more powerful they were, the more shameless they became.

Well, it didn't really matter to him.

As long as he could enjoy tearing them apart and making them suffer, their personalities were irrelevant.

Without another word, Melissa turned and began leading them deeper into the mansion.

The group followed in silence, their footsteps echoing through the grand halls.

It wasn't long before they reached a staircase that lead downward.

Despite heading underground, the path didn't feel like a basement.

The walls still gleamed with divine light, and the floors remained polished marble, reflecting their every movement.

If not for the subtle drop in temperature, one might not have even noticed they had entered a lower level.

At the bottom of the stairs stood a massive door, carved with intricate patterns of gold and silver.

At its center was an angel holding a trumpet, its expression solemn, almost foreboding.

Melissa raised a hand. The moment her fingers brushed the surface, the doors groaned open, revealing a room.

A pool stretched out before them, but unlike the water from before, this one was on another level.

Thick and heavy, it looked like liquid gold.
