Revenge with the Power of the Final Boss

"So, you can’t lie?"

Of course, this could have been an act.
But seeing that he was blurting out things he didn’t need to say, it was clear he couldn’t lie, and if he tried, his true thoughts would be exposed.
"So, you were planning to deceive me."

The fact that he tried to deceive me, even though he couldn’t lie, meant he had attempted to trick me.
"I don’t need your arms to talk, right?"
"Wait, wait just a moment...!"

"Let’s start by hitting you."
I coated my legs with mana and, in an instant, I shot upward with explosive speed, striking his arm with a mana-infused hand chop.
Though a child’s hand chop might seem insignificant, my attack, enhanced with mana and speed, was enough to break the arm of an adult man.

"AAAAHHHHH!!!"
Rupert screamed as he collapsed.
His entire body was pixelated, so I couldn’t tell what kind of expression he had, but just from the scream, I could tell he was in immense pain.

"My arm! Aaaaagh!"
Seeing him clutching his arm in agony, I couldn’t help but sneer.
"You’re whining over something so small? Considering what I’ve been through because of you... I could slowly tear your limbs off and it still wouldn’t be enough."

I’d never killed anyone before, but the thought of killing him now was rising in my mind.
"Please, please let me live! I’ll tell you everything, I’ll speak nothing but the truth!"
Even as Rupert begged for his life, my rage didn’t subside.

If I hadn’t suffered that hellish torment at the hands of the villains, I wouldn’t feel this furious now.
But I had experienced that hell, had begged for death not long ago, and the time I spent escaping it was barely 10 minutes ago.
Now, I was boiling with anger like never before.
However, I wasn’t planning to kill him immediately.

Though I would have enjoyed tearing him apart slowly, I needed the information first.
"Then, if you don’t want more pain, start explaining. Why did you reincarnate me here?"
Rupert struggled to speak through the pain.

"That’s... because someone I don’t know gave me power and ordered me to do this."
"Someone you don’t know?"
"Yes, I… well, I don’t know. After finishing Academy Hero Biography, I suddenly received a revelation in my head, telling me to select reincarnators who would save worlds. I was told there were two worlds to save, and I was asked to choose who to reincarnate into this world."

"One world is Academy Hero Biography, and the other is The SSS-Class Heir of National Power, right?"
"Yes, yes! It seems they wanted someone who knew Academy Hero Biography to reincarnate and make things better."
As he spoke, Rupert nervously glanced at me.

According to what he said, Rupert had become even more of a bastard than before.
"So why did you reincarnate me into The SSS-Class Heir of National Power?"
"Well... I was offended by the critical comments you left on my monitor. And seeing how much you knew about the content, I thought you’d be a good candidate, so I decided to reincarnate you... but when I tried, I saw two people through the monitor. So I decided to reincarnate you, but the light flew away, and the reader at the computer avoided it, so your friend, Seo-mun Yoo-cheon, ended up being the one who got reincarnated."

My friend, Seo-mun Yoo-cheon, had tried to recover from his shattered mind by lying down, only to be reincarnated without knowing why, vanishing without a trace.
"And then you reincarnated me?"
"Yes. I thought I should reincarnate you into another world, so I did. I really regret it. Once I reincarnated you, the person who gave me the revelation forcibly pulled me here and injected me with a lot of knowledge."

"To tell me the truth?"
"That seems to be the case."
This was the situation.

"So you didn’t know that I knew the original work of The SSS-Class Heir of National Power, did you?"
"No, I didn’t."
"You bastard!"

"AAAHHH?!"
I grabbed Rupert’s remaining arm and twisted it forcefully.
"It hurts! Aaaagh! Please, let me go!"

"What did you think would happen if I didn’t know the original work? Even if I had known it, I ended up in this shit situation, begging for death while tasting hell. Damn..."
The pain of feeling as if I were being burned from within was unbearable, just imagining it was enough to cause agony.
But on top of that, I had to endure this unceasing torment while being looked at as nothing more than an experiment by these madmen.

"And on top of that, Yoo-cheon became Seo-mun Hyun in the original! Why did I become Baek Seo-jun, the protagonist’s older brother, when I wasn’t even in the original?"
Yoo-cheon and I were supposed to be the same protagonist’s older brother.
But why did Yoo-cheon end up becoming someone from the original, while I did not?

"Ugh... Well... it seems Seo-mun Yoo-cheon is actually Seo-mun Hyun. I reincarnated him, but it seems that when he lost his memories, the events of the original—so, the record of the future—became his memories."
In other words, Seo-mun Yoo-cheon was originally the same person as Seo-mun Hyun, soul-wise.
The existence of Seo-mun Hyun could only have come about because Seo-mun Yoo-cheon reincarnated. So, in the original story, the future that Yoo-cheon had seen was actually his lost memories.

Therefore, Yoo-cheon had seen the future of himself that he couldn’t remember.
"But why did this happen to me? Why doesn’t my future after becoming Baek Seo-jun exist?"
"Well... the entity that gave me power also gave me the choice to reincarnate you into The SSS-Class Heir of National Power because if someone else reincarnated you, an irregular phenomenon would occur. This is because someone who had received information from another world wouldn’t be able to choose you, but an irregularity would occur if someone else reincarnated you."

"Irregular?"
"Yes. It’s a variable not recorded in the information. Ugh... it hurts so much..."
"So, I’m a variable?"

"Yes. That’s why Baek Hyung-won and Kim Yoo-jung couldn’t see you as their real child. They felt like you were someone else’s child, someone who might try to steal their son’s inheritance."
Baek Hyung-won and Kim Yoo-jung truly felt no parental affection for me.
And while some might argue that it wasn’t entirely their fault, it didn’t matter to me.

"I don’t need to understand why they treated me like that, thinking I was someone else’s child."
A bitter taste filled my mouth.
I understood why Baek Hyung-won and Kim Yoo-jung, who couldn’t view me as their child, treated me as they did.

However, they thought of me as someone else’s child, and that’s why they pushed me into that hell, seeking their own benefit.
Even if the villains weren’t involved, they would’ve used me as a sacrifice for Baek Seo-jin.
The moment they sold me to the villains, there was no excuse left for them.

"But what about Yoo-cheon and me? Did the version of Yoo-cheon and me from our past lives die?"
"Yes. Our bodies disappeared without a trace and were completely obliterated... Ughhh!"
I had already been killed once. By this madman in front of me!

"You killed two innocent people just because they left critical comments! What kind of crazy bastard are you?!"
"I thought you’d be happy to reincarnate... Ughhh!"
I almost killed him right there out of pure rage, but since I still had much to learn, I settled for hitting the spot I had struck earlier again.

"So Yoo-cheon’s world passed more than twice as fast as this one, meaning he’s already in his 20s?"
"Ugh... Yes... But now, since Terenity has been killed, the dimension there has become more stable, which caused time in your world to flow faster."
"I don’t fully understand the mechanics, but essentially, even if 10 years pass here, it’s like less than 5 years over there?"

"That’s correct..."
"Do you know anything about The Fox That Devours Worlds?"
"Not much... I just know that it’s stronger than The Black Serpent That Devours the World but weaker than The Eternal Dragon, Terenity. Unlike the latter, it enjoys slowly manipulating worlds with mana rather than simply consuming them."

"Alright. So, why did you come to find me here? Why am I alive and able to recover in this place?"
"This is... the rift between dimensions."
"A rift between dimensions?"

"Yes. It’s not a passage that leads directly to another dimension, but a space between dimensions. Souls that pass through this space are blessed by the mana here, but those with unfit bodies collapse and break down."
"Souls that pass through... are you talking about reincarnators?"
"Yes."

Most of my questions were answered. Now it was time to solve the remaining doubts.
"Then why were you waiting for me here? Was the entity that gave you the revelation the one who made you wait?"
"Yes... I don’t know much about that entity, but they forced knowledge into me and made me wait for you here. I’ve spent 10 years here, unable to die and only forced to remember my duties. I, too, am a victim."

"Yeah, you’re a victim. But to me, you’re the perpetrator!"
Before Rupert could respond, a sharp tendril shot out and pierced his body.
In this shocking moment, Rupert didn’t even have time to scream.

He simply crumbled away into dust and disappeared without a trace.
The one who pushed me into hell, Rupert the writer, had spewed out his information and vanished without a trace.
Reincarnator.
And then, a strange voice echoed in my mind.

“Telepathy?”
The voice seemed to be similar to telepathic communication or a magic spell used in fantasy novels, much like a message spell.
And the entity speaking to me was likely the one who had just disposed of Rupert.

"Who are you?"
My name is Ramisa. I am the entity you remember as The Black Serpent That Devours the World.
I had finally encountered the final boss of the original story.
