Revenge with the Power of the Final Boss-Chapter 133

The Fox That Devours Worlds burst into mocking laughter, loudly ridiculing him.

“How does it feel, hmm? How does it feel to stab your own mom? Did you feel a sense of accomplishment, knowing it was to save the world? Were you proud, like a hero?”

Her face began to morph, shifting into Kim Yoo-jung’s likeness. Even her voice transformed, taking on Kim Yoo-jung’s tone as she mocked Seo-jin directly.

“Your mom is screaming inside me, begging for the pain to stop. How does that make you feel? Tell me, so I can pass the message along to her~”

Seo-jin wanted desperately to believe it was all a lie. But even though the words came from his enemy, denying them felt impossible. Denial would mean returning to the life of avoidance he had left behind.

Desperate for clarity, he turned his gaze to Baek Seo-jun, silently pleading for his brother to refute the claim.

But Seo-jun’s voice was as cold as ice.

“She’s telling the truth. I sealed that Extraterrestrial inside Kim Yoo-jung’s body.”

“Ah, call me Hee-ah, won’t you?” the Extraterrestrial chimed in. “You’ve earned the right to use my name~ Ahahaha! I was wondering who was messing with my plans, but wow, this turned out to be way more fun than I expected!”

Despite the injury she had sustained, Hee-ah clapped her hands in amusement.

“I… I stabbed... my mom.”

Seo-jin collapsed to his knees, the weight of the revelation crushing him.

The realization that Seo-jun’s desire for vengeance had driven him to orchestrate such an act left Seo-jin in shock.

He could now fully grasp the depth of Seo-jun’s hatred and the pain he had endured since their childhood—the fury that had been born when their parents sold him to villains at the age of ten.

The torment Seo-jun had suffered as a test subject, combined with his relentless thirst for vengeance, was far beyond what Seo-jin had imagined.

"He made me stab my own mom with my own hands."

Even though Hee-ah controlled Kim Yoo-jung’s body, Seo-jin knew that his mother had likely felt every wound he had inflicted.

In essence, Seo-jun had forced a battle between mother and son.

"I can’t even blame him for this."

Seo-jin realized there was no one he could hold accountable. The horrors inflicted upon Seo-jun by their family justified his brother’s vengeance.

Memories of his parents’ unrepentant attitudes came flooding back. He recalled how they had even lamented not killing Seo-jun earlier, showing no remorse for their actions.

It was only natural that Seo-jun would exact his revenge.

This truth tore at Seo-jin’s spirit, driving him into despair.

Unable to hold himself up any longer, Seo-jin collapsed. His battered body hovered in mid-air before being flung aside as if discarded.

Seo-jun had removed him from the battlefield.

“So, it’s just the two of us now?”

Showing no interest in Seo-jin, Hee-ah redirected her attention entirely to Seo-jun. Smiling, she touched the wound on her side, her demeanor calm and collected.

“Do you think you have the upper hand now? Sure, we’re both weakened inside this barrier, and I’m slightly injured, but…”

Before she could finish, Seo-jun interrupted her with a frigid tone.

“You’re not afraid at all, are you?”

“Ahahaha! Nooo~! I’m sooo scared! Please don’t hurt me!”

Her mockery was so exaggerated that it was impossible to take seriously.

Seo-jun didn’t bother responding with words.

Instead, countless black tendrils erupted from the ground and the air, each one tipped with razor-sharp points, hurtling toward Hee-ah with terrifying precision.

“Oh my!”

Sensing the immense power imbued in the attack, Hee-ah quickly rolled to evade it.

“Ahaha! That power! It’s not even yours, is it?”

Hee-ah’s laughter rang out again, her tone a mix of amusement and taunting disbelief.

Rolling on the ground to avoid the black tendrils, Hee-ah’s body was now covered in dirt. Yet, she paid no mind to her disheveled state, laughing instead.

From the energy emanating from Baek Seo-jun’s attacks, Hee-ah had discerned the origin of his power—it was the energy of Ramisa, the Black Serpent That Devours the World.

While Hee-ah had never been particularly interested in Ramisa, dismissing it as a lesser being, she immediately recognized the unmistakable aura of an Extraterrestrial.

“So, you’ve made a contract with an Extraterrestrial, huh?”

“Stop wasting your breath and just die.”

“Wait a moment~”

Hee-ah raised a hand, gesturing for Seo-jun to pause. With a sly and seductive tone, she asked, “Can you really trust the Extraterrestrial you’ve made a deal with? Are you sure it won’t deceive you? Betray you when you least expect it?”

Her voice was laced with manipulation, her words calculated to unsettle. It was her most potent weapon—a persuasive, honeyed tongue capable of sowing doubt in even the strongest minds.

While she had chosen not to use this ability on Seo-jin, preferring to toy with him, Hee-ah had saved it for Seo-jun, aiming to shake his resolve.

“Did you carefully read the terms of your contract? Or could it be using you to eliminate me, only to devour this world once I’m gone? Have you never questioned its intentions?”

Despite her cunning words, Seo-jun responded with a faint chuckle.

“Huh?”

Hee-ah tilted her head, genuinely perplexed by his reaction.

“Listening to you ramble like this... I can tell you’re desperate. Makes sense. This world’s will is pressing down on you, isn’t it?”

The difference in strength between Seo-jun and Hee-ah wasn’t significant under normal circumstances. For Seo-jun to weaken Hee-ah and maintain the barrier binding her, he had to endure significant strain himself.

However, one decisive factor tipped the scales: the will of the world.

While the world’s will rejected and suppressed the Extraterrestrial invader, it lent its support and power to Seo-jun as its chosen guardian.

Unlike Seo-jun, Hee-ah had not descended into this world of her own accord. Dragged here by the world’s will, she was forced to endure constant pressure, weakening her further. This allowed Seo-jun to restrict her movements and give Seo-jin the opportunity to strike earlier.

“Wait, wait. Do you seriously trust that Extraterrestrial? Really?”

“At least it’s far more trustworthy than you.”

Despite Hee-ah’s manipulative words, Seo-jun remained unshaken. His faith in Ramisa was unyielding, impervious to her cunning attempts at persuasion.

“Hold on, hold on! Let’s talk this out!”

As Hee-ah’s tone grew increasingly desperate, Seo-jun coldly unleashed a flurry of black tendrils, driving them toward her with merciless precision.

[Aaaaagh!]

The tendrils pierced through her body, one after another, not just tearing through flesh but also ripping into her very soul.

The essence of The Fox That Devours Worlds—its spiritual form—was impaled and shredded, writhing in agony as Hee-ah screamed.

“It hurts! It hurts! Aaaah!”

Through her anguished cries, Seo-jun spoke with chilling detachment.

“I don’t hold any personal grudge against you. But I want this world to continue existing. So, die.”

“W-wait! Let’s make a deal! I’ll offer you a better deal than that Extraterrestrial! I’m meticulous, trustworthy—”

“I’m not interested.”

Seo-jun interrupted her plea without hesitation, driving the tendrils deeper, tearing apart her spiritual essence until nothing remained of her Extraterrestrial core.

"An Extraterrestrial cannot truly die unless its essence is destroyed," Seo-jun thought. With that in mind, he executed his attack flawlessly, ensuring that Hee-ah’s essence was utterly annihilated.

“It’s over.”

Without so much as a final scream or a parting curse, The Fox That Devours Worlds disintegrated, erased from existence.

“Ugh… aaagh…”

With Hee-ah’s presence gone, Kim Yoo-jung regained control of her body. Weak and trembling, she collapsed onto the ground, her gaze meeting Seo-jun’s as she lay there.

“You did well, Kim Yoo-jung,” Seo-jun said coldly. “If it weren’t for you, I wouldn’t have been able to win this easily.”
