Villain: Ultimate Mutation System in the Alternate World

The devil's language was not something that could be learned just from reading or studying.

It had the same concept as the Divine Language. Both could only be understood by their respective races .

In fact, even within their respective races, those languages could only be utilized to its full potential by those strong enough to contain the power of those words.

She decided to remain neutral for now and act as though she believed him .

"I understand, hand it over, and I'll make the changes as per your terms," she said softly, extending her hand to receive the contract back.

"Like I said, no need for that," Reign shook his head.

He focused his thoughts in devil's language, and to Lilith's astonishment, the contract began to vibrate faintly.

Drops of blood fell from it, and new words appeared as if written by an invisible hand.

"I— Impossible!" Lilith gasped, realizing that he was rewriting the entire thing.

And not just that, he was able to changed it with ease, indicating that his soul was far stronger than hers.

Reign was unaware that the contract had a loophole.

Devils always had an advantage in writing it, using their powerful souls to subtly manipulate interpretations to their benefit.

However, it was a different scenario when the person in question could understand and even write in the Devil's language.

Now she felt like she had pushed herself into a corner.

The contract was made partially from her soul, and now that Reign began to rewrite it, she saw three options: sign it, negotiate, or reject it.

"It's done," Reign threw the contract back .

The text was now at least tripled in word count.

'This…' Lilith was speechless after reading it.

The number of words showed how powerful Reign's soul was.

She was a Royal Devil, and even she couldn't write this much, as each letter would take away a bit of soul from the user.

Little did she know, Reign's soul had already been heavily tempered.

'I also don't see anything wrong with it,' she thought.

It was too detailed. He had patched all possible loopholes, and even she could not see any reason to reject it.

The contract protected him, and as long as she followed it, then there wont be any issue at all.

But there was one thing that made her raise an eyebrow.

"In the event that I fail to adhere to the contract, instead of death, I will be your slave?" she repeated those words and looked at him weirdly.

"Why? At least it's not death," he explained .

"I think you misunderstand. A devil's contract can only result in death for a breach. You can't just add your own punishment. It doesn't work like that," she replied, shaking her head.

Who did he think he was to alter such a powerful tool that had existed before even this world was created? God?

"Oh, don't worry," Reign chuckled, a cruel twist in his smile. "This isn't just some devil's contract anymore."

Lilith was unsure of what he meant, so she decided to study it more carefully.

This time, she used her soul to resonate with it, and though fundamentally the same, she realized it had been tampered with—not just the content, but even the death sentence had been removed.

"This is impossible. How did you change the nature of the devil's contract?" she wondered aloud.

"I have my means. So, are you going to sign it or not?" he asked while releasing his aura to stop her from asking so many questions.

He now appeared more powerful and intimidating in her eyes, thanks to all his past feats, which made her reconsider his strength.

This was the power of psychological warfare.

Despite being a devil, Lilith was an intelligent being susceptible to such tactics, and Reign had effectively portrayed himself as mysterious and powerful being.

It was a classic case of "fake it till you make it."

'Who are you?' she wondered, now feeling that her identity as a devil was not as impressive and mind-blowing compared to the person in front of her.

'Maybe he can do it?,' she thought.

Initially, she had seen Reign as a unique creature, but after witnessing all that he had accomplished, she began to believe he could be more than just extra muscle for her goal.

Her plan required someone capable of reading ancient languages that she had been searching for—an object on this planet planted by her predecessors.

Reign seemed to have the ability to understand unique languages, so he might be her ticket to accessing that legacy.

"I'll sign it," she agreed.

In the contract, the time frame was only six months, which, for a devil like her, was relatively short.

This made her think that it wasn't such a bad deal after all.

"Good," Reign nodded, satisfied by this turn of events.

He had intentionally included the six-month rule to trick her into signing it.

By doing so, she didn't even consider that this contract heavily restricted her because she was focused on the short time frame instead.

Lilith, after thinking it through, raised her finger and bit it.

One droplet of blood flowed from her finger, which she used to sign the contract.

As her blood touched the skinned texture paper, the parchment glowed with an eerie red light.

The ink absorbed her blood, the symbols shifting and twisting as if coming to life.

A surge of power pulsed through the air, and the contract emitted a faint hum, signifying the binding agreement.

The glow faded, leaving it slightly warm to the touch.

Suddenly, it flew towards Reign before burning away, leaving a black tattoo that appeared on his forearm.

The tattoo didn't concern Reign at all because the system had already assured him that it was safe.

In fact, it was thanks to the system that he had been able to change the contract. He took advantage of this revelation to deceive her.

'I can't believe I just tricked a devil. What a twist,' he chuckled to himself, feeling proud of his achievement.

He was unaware that the only reason she agreed to all of this was because she wanted to build a bridge for future cooperation.

Both of them were playing each other, but it was still too early to tell who had tricked whom.

When everything was settled, Reign found himself back in the yard as if nothing had happened.

"You!" Dan released his aura out of anger after being freed.

Beside him, the other members of their group looked equally wary and ready for a fight .

Lilith stepped forward, raising a hand to calm the situation. "He's not our enemy,"

She walked towards Reign and offered her hand.

"He's my important guest," Lilith said with a sweet smile forming on her lips, already beginning to treat him more favorably in accordance with her plan.

Reign noticed her action and decided to humor her for now.

"Come, I know you have a lot of questions," she added.
