Villain: Ultimate Mutation System in the Alternate World

"So, what's next? Where is it?" he broke the silence, his voice bouncing off the walls of the capitol's underground basement.

The air was thick, and everything smelled old, like wet stone and rusted metal.

Lilith led the way, moving quickly through narrow halls and under low, crumbling arches.

She had told him earlier that the place they were looking for was deep underground.

"It's is buried far below," she said, not looking back.

"How far?"

He sounded impatient, wanting to know more.

"I don't know the exact distance," she shook her head.

"We're wasting time here. It'd be faster if I just dug a hole straight to it," he suggested.

Lilith paused for a moment. "I don't think that's possible. If you use too much force, the whole place could collapse."

"Don't worry about it," He walked forward, stopping to point at the ground. "Is this spot okay?"

"Yes," she nodded, unsure of what he had in mind.

But he was right—they had wasted too much time already.

If he had a way to speed things up, she wouldn't stand in his way.

"Got it," he gave her a nod , his gaze dropping to the ground as he began controlling his power.

Though his abilities in this second body were weaker than his original, it possessed one key advantage—every core was entirely dedicated to divine energy.

This trait set it apart, allowing him to harness and control divine power with a precision and intensity that even his original body couldn't match with a single element.

'Heavenly King Mode,' he uttered.

BOOOOOM!

His energy surged , but this time, it wasn't golden light. Instead, a darker force emerged—pure black energy that seemed to absorb everything around it.

It had no aura, no signature, but it looked intimidating. This was the advantage of "System Cloaking," which concealed the true nature of his power.

As the dark energy swirled around him, his overall appearance began to change.

His hair and eyes darkened, shifting to a deep shade that matched the energy surrounding him.

At the same time, a crown materialized in his forehead, made from pure energy so condensed that it took on a solid form.

As he raised his arm, a jet-black staff gradually come into existence , its surface smooth and devoid of light, resembling a solid beam of darkness.

The energy surrounding it made the air vibrate, yet it emitted no sound.

"EXTEND!" he commanded.

The staff shot downward, piercing the ground and burrowing through it, obliterating sand, stones, and any material in its path inch by inch.

Reign stood still, casually holding the staff in his right hand. He even looked bored.

When he sensed it had gone deep enough, he clenched his fist and issued another order.

"EXPAND!"

At his command, the staff widened in all directions.

The energy cut through the earth as if it were nothing, leaving no debris behind—just a smooth, clean passage.

It was large enough for both of them to jump down into.

Lilith stood frozen,

'What kind of power is that?' she was lost for words.

There were no explosions, no mess—just pure, penetrating force.

Reign turned to her, his eyes calm, treating what he had done like a simple act.

"Let's go," he said, gesturing toward the hole.

'Is this his true power?' she wondered, realizing she had seriously underestimated him.

Little did she know that what she saw was just a droplet of his true power.

Reign, on the other hand, was puzzled by her reaction. To him, it was a simple feat—he didn't even find it all that impressive.

'Is it just me, or is she pretty weak?'

He had never figured out her power because she never used it around him.

Since she didn't just tear a hole in the ground as her first option, he could only assume she wasn't the type with a lot of firepower like him.

Maybe her abilities relied on illusions or, even worse, mental tricks, which made her more dangerous in his eyes.

Or maybe she was just feigning weakness to gauge his true power while keeping hers hidden.

Reign didn't really care either way what her plan was; this was just his second body. If she dared to betray him, he would erase her and the entire city from existence with his original one.

"Ladies first," he called out to her again.

Lilith nodded and jumped. Reign followed closely behind .

It took them more than a minute to finally reach the end of the hole, or so they thought.

Instead of landing on solid ground, they continued to fall until they spotted a light at the end.

As they passed through it, they were greeted by a large cavern with tall glowing ceilings while they where in freefall.

In the distance, a massive temple came into view. It looked familiar, and he could sense a powerful energy emanating from it.

'That's a pyramid,' he recognized it.

It was not the type of structure normally seen in the vast deserts of his past world.

Instead, this one closely resembled the grand structures built by the Mayans, rising majestically against the backdrop of a ceiling adorned with glowing green crystals.

The stone walls were weathered and gray, covered in patches of vibrant green moss that clung to the surface, adding a touch of life to the otherwise stoic structure.

Surrounding the pyramid was a forest of its own, filled with large vines that sprawled across the ground .

The vines twisted and turned, some climbing the pyramid's sides while others hung low, covering the ground.

Reign and Lilith landed on one of these thick vines, feeling its softness beneath their feet.

'Did we get isekai'd into a fantasy world?' he joked, recalling a term popular in his past world.

Seriously, though, this was definitely unlike anything he was used to.

No toxic miasma, no noisy, dirty urban landscape—this place was peaceful and untouched by humans for a very long time.

It was almost miraculous that such a place, so deep underground, could actually sustain an ecosystem.n/ô/vel/b//jn dot c//om
