I Was Reborn in Another World, But I Awoke Inside a Corpse

Chapter 135: Fusion—Ω

The air beneath the roots of Yggdrasil had gone still.

Not just quiet—hushed, like the very breath of the world was waiting.

Isaac stood alone in the aftermath. The bones of the battle lay scattered around him—cracks in the stone, blackened ichor drying in rivulets, and the fading echo of a Sin's death scream still reverberating through the cavern's pulse.

But none of it mattered.

His eyes weren't on the wreckage. They were locked on the system window hovering before him.

[Skill Selection Complete]Selected: [Devouring Loop – Rank EX+]

The skill pulsed with presence. Even in text, it radiated hunger.

He clenched his fist.

"Too strong to leave as-is. Too connected to Beelzebub. It needs to become mine. Entirely."

He opened another interface.

[Skill Fusion Protocol – Rank EX]Source Skill A: [Soul Devourer Matrix – Rank EX+]Source Skill B: [Devouring Loop – Rank EX+]Compatibility: 100%Result: UnknownProceed?

Isaac didn't hesitate.

[Confirmed.]

The world changed.

A spike of system feedback lanced through him—cold fire threading every nerve, every bone. His knees buckled. The fusion sequence wasn't like the last one. This wasn't merging relics or enhancing passives.

This was fusing two cosmic-level devourer protocols, both designed to bend reality around death itself.

The interface flickered.

[Warning: Fusion exceeds classified threshold.][System recalibration in progress…][Calculating compatibility across Ω-scale…][Creating new classification...]

A roar like a windstorm in reverse sucked the ambient mana toward him. The air warped. His soul buckled under invisible pressure.

Then—

Stillness.

A single line remained in the air:

[New Skill Created: Devourer Omega Matrix – Ω Rank][Updating status interface…]

The system interface trembled, as if even it struggled to display the result. The background turned pitch black. A circular glyph—twisted, elegant, infinite—etched itself behind the new name.

Isaac opened the new skill's description:

[Devourer Omega Matrix – Ω Rank]

Absorbs 30% of all base stats (including Luck) from any being that dies or any corpse touched—regardless of who dealt the killing blow.

Bypasses ownership, proximity, and claim mechanics.

Acquired skills have a small chance to increase in rank (e.g., E → D, D → C, etc.).

Has a chance to acquire multiple skills per devoured soul.

He read it once.

Twice.

Then again.

No cooldowns. No restrictions. No daily uses. It had the best of both parent skills and none of the limitations.

He took a breath—and the air tasted different. Heavy with potential. The type of potential that reshaped worlds.

[Ω-class designation registered.][New Rank Tier: Ω][Warning: Skill power exceeds system-standard ceilings. Broadcast disabled.][Skill fusion report: Not shared with other users.]

Isaac let out a long, slow breath.

"Good," he murmured. "Let the world think I just absorbed Beelzebub's energy. Let them believe this was just another win."

He turned his gaze upward, toward the faint light filtering in from the split in the cavern ceiling where the roots of Yggdrasil trembled.

[System Message – Private Only]You have become the first recorded Ω-tier Devourer. No titles assigned. No records updated.You exist outside the boundaries.

He smiled faintly.

That fit him better than any godly title.

Footsteps approached from the distance—soft and familiar.

Sylvalen and Lira.

They were just now stepping into view, silhouetted against the faint glow of divine roots above. Neither had seen the fusion. Neither had seen the system window.

Isaac closed the interface and straightened his coat.

He looked like a man recovering from battle—worn, battered, and victorious.

Exactly what they expected.

And that's what he gave them.

"Isaac!" Lira's voice echoed across the chamber. "Are you alright?"

Sylvalen's eyes scanned him with sharp precision. "You're bleeding…"

He gave a tired smile, walking to meet them.

"Just a few scratches. Beelzebub put up a fight."

They didn't ask about the skill. They didn't have to.

He'd made his choice.

This power isn't for the world to know.Not yet.Let gods, demons, and kings play their games.

I'll be the one who rewrites the rules when they forget someone like me exists.

Far behind them, the blackened stone still smoldered. The scent of ruin lingered in the air. The remnants of Gluttony's domain were silent now.

But inside Isaac?

A new hunger stirred.

Not Beelzebub's.

His own.
