Villain: Ultimate Mutation System in the Alternate World

As Reign ripped into the Corrupteds' bodies, he found their external ure to be gooey, resembling a thick, dark substance.

However—

Their internal organs was still intact, although filled with a dark-colored tumor and emitting a foul odor.

While the sight and smell might have be repulsive to others, Reign, accustomed to the sct of blood and internal organs, didn't find it particularly bothersome.

Instead, he became curious about the tumor-like patches within their bodies.

Attempting to absorb it, he tried to discern if it was a type of virus he could use, but there was no response.

This suggested it was another substance altogether.

'System, why do you reject this miasma?' Reign inquired, hoping for a response from his system, which had be responsive lately.

However, this time it failed to provide him with an answer.

Well, he did not really mind the silce; he was only trying his luck, anyway.

On his side, Arc moved like a killing machine, each swing of his sword slicing through the horde with a crimson lightning arc.

Despite his monotonous movemts, Arc's efficicy was not the least effected.

His emies lacked strategy, mindlessly charging forward, making it easy for it to dispatch them with each strike.

"Cover me," Reign ordered, and without wasting any time, he began devouring the Corrupted.

Unlike consuming normal humans, this process was very differt.

The Corrupted had no taste, and they were absorbed into his body much more quickly

He assumed that only a portion of the Corrupted was useful to him, judging by how he was now releasing black miasma on his back to protect his body from being affected by it.

To accelerate the process, he utilized his Serpt Vertebrae to construct multiple long whip-like limbs.

With precise control, these dozs of thin limbs pierced through the dead Corrupted, making the absorption process way faster.

While he was busy absorbing his spoils, he observed Arc's movemts with ke interest.

The more it fought, the more its movemts improved.

ARC's actions became more diverse, adapting seamlessly to dispatch numerous Corrupted without expding unnecessary ergy.

"He's improving, almost like he's remembering his old self," he mused inwardly, observing Arc's progress with a sse of satisfaction.

Seeing this, he decided to be on the sideline for now, if this thing could improve Arc more , th he did not mind just watching.

"I feel like a trainer... Arc, use Thunderbolt!" Reign commanded with a hint of amusemt.

In response, ARC raised its sword and summoned red lightning, striking the g and obliterating hundreds in one fell swoop.

'Yeah, that's ough playing a,' Reign chuckled to himself.

If he kept at it, he might have to find gym leaders, collect badges, and th spd 5 years without aging just to finally become the world champion.

But joking aside .

He commanded Arc to refrain from using flashy attacks and instead focus solely on its sword skills.

After 30 minutes, the horde of Corrupted was finally starting to thin down , he would supply Arc ergy from time to time , but he did not mind because it was an investmt.

The Arc right now was a far cry from before. It was more agile, more flexible, and the way it wielded the sword closely resembled the original.

'Beautiful' Reign mused inwardly.

Watching Arc effortlessly kill the Corrupted with its sword made Reign feel like he was just a crude butcher hacking away at meat.

If Arc was the elegant chef delicately slicing through ingredits with finesse, th Reign was definitely more like the butcher, wielding his claw with all the finesse of a caveman wielding a club.

'Should I learn how to wield a sword too?' Reign pondered.

If he knew how to wield a sword, th he would be able to fight without taking off his mask and just pretd to be a master swordsman.

'Let's see, '

He focused his mind, summoning a long bone that protruded from his arm.

With a mtal command, the bone transformed, morphing into a black-red katana with a hilt crafted from a sinister-looking skull.

"Sweet," he whistled, admiring the imposing katana he had just crafted. Its dark-red patterns gave it a powerful and intimidating appearance.

"RAWWWWR!" T Corrupted darted past Arc, charging directly at Reign.

He glanced at his sword, pondering how to wield it effectively. After some consideration, he awkwardly decided for a horizontal swing.

SLASH!

The Corrupteds fell as Reign swung his sword effortlessly.

It resembled a child playing with a toy, but the swing itself gerated shockwaves, accompanied by a whooshing sound akin to a jet plane taking off.

'Is this what they call talt ?' Reign chuckled, amused by the damage he had done while not ev putting much of an effort.

If a Hunter were here right now, they'd probably roll their eyes so hard they'd see the back of their heads.

They'd likely think Reign's swing was the most sorry excuse for an attack they'd ever witnessed.

Hell, ev a -year-old Hunter in training would probably have better form.

With no one a to criticize, Reign swung his sword as clumsily as possible, but thanks to his stats, each swing dealt more damage than Arc's precise strikes.

As he continued swinging his sword, Reign's motions grew more polished.

Surprisingly, he progressed at a quicker pace than Arc, despite merely mimicking its actions.

Once again, his ability to grasp things quickly was big advantage, after minutes , Reign sword movemts was in no way inferior .

He ev began using Stream Guide, hancing the power behind his swings.

With the two of them hacking through everything in their path, the horde of monsters finally died down, leaving only the duo standing side by side.

Ironically, Arc looked more like the main character, with a reddish shadow and arcs of lightning suring it.

After making sure that there was no longer anyone left to kill, Reign unsummoned Arc and began absorbing the corpses again.

[ Level up + ]

[ Level up + ]

In the d, he only leveled up twice after killing so many.

It just showed how heavy the EXP debuff was wh devouring Corrupted. It was like doing 40 times the work for the same result.

[Ding]

[System: Host has refined Dark Dust = 30,567 Dust was refined.]

'Dark Dust?' Reign was puzzled , this was a new term that he was no familiar with.

[System: Dark Dust are very small fragmts resulting from the refining process of Corrupted. They materialize the fear, hatred, and anger that the corrupted felt before they turned into one.]

"What are they used for?" Reign asked.

He couldn't care less about the fear and hatred part; they were dead anyway. He was more curious about the befits.

He thought that all of this was not worth the effort, but this Dark Dust could be a game changer.

[System: The function of Dark Dust will be available after the Host reaches level 30.]

'Level 30, huh?' Reign mused, realizing that reaching that level would be a challge.

Devouring humans would have made it easier, but these creatures didn't provide much EXP.

Unfortunately, he couldn't just dismiss the Corrupted and the pottial of Dark Dust.

Whatever function unlocked at level 30 must be worth the effort.

'No doubt about it,' Reign mused confidtly. 'The system wouldn't put that function at such a high level without a good reason.'
