tensura: I don't know

Velnova rested deep within Veldora's cave, his translucent form barely shifting as he processed the flood of souls within him. The moment had come. He had delayed long enough.

"Great Sage, begin the Harvest Festival."

[Confirmed. Initiating Demon Lord Evolution.]

"And one more thing—hide it. I don't want anyone sensing my transformation."

[Understood. Suppressing all external magical fluctuations.]

At that command, the process began.

A flood of power surged through him, vast and overwhelming, yet perfectly controlled. The souls he had collected—12,170 lives reduced to fuel—burned within his core, reshaping him at the most fundamental level.

[First Blessing: Complete Nullification Series Acquired.]

The changes hit instantly.

Pain—gone. No sensation of harm would ever reach him again.

Heat, cold—meaningless. Flames of the hottest hell, ice of the deepest void, neither would touch him.

Holy and demonic forces—nullified. No sacred blessing, no cursed malice could affect him.

Spiritual and physical attacks—erased. Swords, magic, even reality-breaking curses, all rendered powerless.

Poisons, diseases, mind control—irrelevant. His body, his soul, now untouchable.

Velnova pulsed, absorbing the transformations in silence.

"So this is what it means to evolve…"

And yet, this was only the beginning.

Velnova's form trembled as his evolution surged forward, deeper and more profound than any ordinary Demon Lord's transformation. Unlike others, he had no need for a physical cocoon—Great Sage ensured the process remained hidden, locked away in absolute secrecy.

[Second Blessing: Evolution into True Demon Slime.]

His core burned with boundless power, his very existence shifting beyond mortal comprehension. Unlike a standard Demon Lord ascension, Great Sage was pushing the limits, exploiting the Infinity Attribute to its fullest extent.

His body compressed, then expanded—his very nature rewriting itself.

A normal Demon Lord would gain immense strength.

A True Demon Lord would be feared across the world.

But Velnova?

He transcended them all.

[Due to optimal resource allocation, True Demon Slime evolution is 300% more efficient than standard Demon Lord evolution.]

His previous abilities sharpened into perfection.

Pain Nullification → Absolute Pain Immunity – Even conceptual attacks designed to inflict suffering would fail.

Thermal Nullification → Absolute Temperature Control – He could walk through a sun or freeze reality itself.

Holy/Demonic Nullification → Divine & Abyssal Supremacy – He now ruled over both light and darkness.

Spiritual & Physical Nullification → Absolute Existential Defense – No being, no law of existence could erase him.

Abnormal Condition Nullification → Ultimate Status Immunity – Mind control, curses, fate manipulation—irrelevant.

The cave trembled under the sheer force of his evolution, cracks forming along its ancient walls. Even sealed away in his stomach, Veldora stirred, sensing the shift.

Velnova's transformation was nearing its peak… and the world had yet to realize what had just been born.

As the Harvest Festival progressed, Velnova's body pulsed with overwhelming power. His existence was no longer bound by the limitations of a mere slime or even a Demon Lord. Every cell in his being was reconstructed to surpass all living creatures.

[Third Blessing: Universal Adaptation Complete.]

New abilities emerged, far beyond what ordinary Demon Lords received:

Infinite Regeneration – His body could rebuild itself instantly, even if erased from existence. Destruction was meaningless.

Universal Sense – He could perceive everything, everywhere, at all times. No illusion, no stealth, no deception could hide from him.

Universal Shapeshift – He could assume any form, any mass, any density, even replicating conceptual entities.

Every skill he previously possessed had evolved, each one refined to perfection. He wasn't just a Demon Lord. He was the pinnacle of all demon lords evolution.

The cave groaned under the weight of his ascension. Even with Great Sage concealing the event, reality itself struggled to contain him. His core pulsed like a black hole, devouring all limitations, all restrictions.

[Final Phase: Skill Consolidation and Optimization Initiated.]

Velnova's transformation was nearing its peak. And soon, the world would tremble.

The evolution surged forward, reshaping Velnova's existence. His power swelled beyond limits, yet something was missing—an obstacle even Great Sage hadn't foreseen.

[Attempting Evolution: Great Sage → Wisdom King Raphael…]

[Rejected.]

A tremor pulsed through his core. Then another. And another.

One billion times.

Each rejection sent waves of instability rippling through his being, a paradox of power and limitation. But Great Sage did not falter. It analyzed. It calculated. It adapted.

The answer lay in the very souls he had devoured—the 12,170 human lives that had ceased to exist. They were no longer individuals, but raw energy, a foundation waiting to be repurposed.

[Applying Infinity Attribute… Utilizing stored souls as an anchor.]

The Voice of the World, the absolute law that governed all existence, hesitated. The logic was irrefutable. The calculations, absolute.

It could not reject what had already been rewritten as inevitable.

[Evolution Successful.]

A new existence took shape within him.

[Great Sage has evolved into the Ultimate Skill: Wisdom King Raphael.]

[Due to Infinity Optimization, efficiency increased by 500%.]

Velnova's mind expanded, accelerating beyond mortal comprehension. His thoughts processed reality itself as numbers in an infinite equation. Time felt insignificant. Knowledge no longer required effort—it simply was.

This was no longer just a skill.

It was absolute intelligence.

The cave fell silent. In the depths of Velnova's stomach dimension, Veldora stirred, an unfamiliar unease creeping through him.

Something far beyond a Demon Lord had just awakened.

The moment Raphael returned to Velnova's body, a surge of energy rippled through his core. He could feel it—his existence had transcended. His power had grown.

But something was missing.

[Attempting Evolution: Unique Skill 'Gluttony' → Ultimate Skill 'Beelzebuth'…]

[Error. Evolution requirements not met.]

Velnova's core pulsed with irritation. Why?

[Analysis Complete.]

[All available human souls were expended in the Demon Lord ascension. The skill 'Merciless' is required to extract additional souls for further evolution. Additionally, the Harvest Festival has ended.]

Velnova's form rippled. He had been so close. The power he sought was right there, just beyond his reach. But without a way to harvest more souls at will, he was stuck.

For now.

Raphael, standing within his consciousness, bowed slightly. "Master, the path forward requires more preparation."

Velnova pulsed with amusement. Then we prepare.

His evolution had stalled, but it was far from over. He would find another way.

He always did.

Velnova's mind surged with questions, his thoughts firing in rapid succession.

"Raphael, how different is my evolution from Rimuru's?"

"Why did I get the Infinity Attribute? Was it because of how you optimized my evolution?"

"How did you even manage to evolve when the Voice of the World rejected it a billion times?"

"What caused you to manifest in my consciousness as a separate entity?"

"Was it because of the Infinity Attribute, or did something else influence your birth?"

"Why did my power increase threefold compared to a normal Demon Lord?"

"Is my soul different now? Did the Infinity Attribute change my existence fundamentally?"

"How did I acquire those nullifications? Were they a natural part of the evolution, or did you forcefully integrate them?"

"Why couldn't Gluttony evolve? Would it have turned into Beelzebuth if I had Merciless?"

"If I got more souls, would I be able to evolve it now, or is it too late?"

"Does the Infinity Attribute affect all my skills? Will they evolve differently than in canon?"

"Did my body change significantly? Am I stronger physically, or is my power mostly in my skills?"

"What's my current magicule count? How does it compare to Rimuru at this stage?"

"Are there any side effects to this evolution? Any unknown variables you couldn't calculate?"

"What's my next step? How do I push my evolution even further?"

Velnova's form pulsed with anticipation. He demanded answers.
