Harem Startup : The Demon Billionaire is on Vacation-Chapter 611: Infernal Sovereign

Chapter 611 – Infernal Sovereign

This wasn’t that thrilling, addictive heat that came from a good fight or a dirty win. No. This was deeper. A weight curling under his skin, humming through his bones like someone had just filed a divine merger without telling the shareholders.

"Wait," Lux muttered. "Hang on... wait."

Mira sat up a bit, frowning as she adjusted the qiaopao back over her shoulders. She was still flushed. Still breathing fast. Still sticky from what they just did. But she could feel it too.

Lux reached into the ether with one hand, fingers slicing through invisible locks until his dimensional inventory opened. The system shimmered. He flicked his wrist, and something solid dropped into his palm.

Zoltarin’s demonic core.

Or rather... what should’ve been.

It was black and gold. Dense. Like obsidian with veins of pure sin mana running through it. The size of an apple. Warm in his hand. But something was wrong.

He tilted it.

No pulsing. No glow.

It looked... empty.

[System Notification]

[Zoltarin’s Core – Status: Inert Shell]

[This artifact no longer contains active essence. Core power: 0%]

Lux stared.

"No no no no... don’t say it—"

-Crack!

The artifact split in his hand. A thin fracture down the middle, hissing out faint sparks of dead mana.

-Crack... tinkle...

Then it shattered. The shards turned to glittering dust in his palm and blew away like ash caught in a divine audit.

Lux stood there.

Still naked. Still slightly hard. Covered in sweat. Holding absolutely nothing.

"Oh Holy Hell," he muttered. "Please don’t say what I think you’re gonna say..."

He swung his hand, frustrated. Opened the system. "Status."

His eyes stopped at the word.

’Infernal Sovereign.’

"...Huh?"

He blinked at the class title, confused.

"I’ve never seen that before," he muttered. "What happened to ’Prince of Greed’? Why does this sound like I just got a promotion I didn’t apply for?"

The system chimed in.

[System Explanation: Upon defeating a demon of equal or higher tier, with a compatible sin lineage, the remaining essence was absorbed directly into the host.]

[Zoltarin’s demonic core could not be stored externally. Automatic assimilation triggered.]

[Body adjustment in progress... adjustment completed.]

[Reason for neural damage: Royal grade Sin Merge requires full nervous re-routing and core harmonization.]

[You are now the sole inheritor of Zoltarin’s Greed Line Sub-Domain.]

Lux blinked.

He squinted at the screen like it owed him a refund.

"So wait," he said slowly, "I didn’t lose the core. I ate it."

[Correct.]

"Without knowing?"

[Correct.]

He groaned. "You could’ve warned me!"

[You were unconscious.]

"Then wait until I wake up!"

[No.]

Mira, who had been quiet until now, finally asked, "So... you merged with your uncle’s core?"

Lux nodded, still stunned. "Yeah. That explains the nerve damage, I guess."

"And the rope snapping?"

He looked at her. Then at his hands again.

"...Also that."

"Okay," she said slowly. "So what’s... different now?"

Lux frowned. "I don’t know. It’s not like the system gave me a tutorial—"

[Suggestion: Test Your Weapon Summons]

"...I stand corrected," he muttered.

He raised his hands again.

"Summon: Devorare."

The Greed blade bloomed into existence. Gold edge. Black hilt. Hungry, pulsing with sin mana. But different. There was a faint glow at the tip now. A spiral rune rotating slowly just beneath the surface of the blade.

[Devorare – Greed Blade]

[Effect: Now drains ambient mana from nearby enemies. Gains +10% damage per active drain.]

"Ohhh," Lux grinned. "Nice."

"Summon: Amare."

The Lust dagger flickered into his other hand. Crimson. Elegant. It shimmered with subtle magic, but now when he gripped it...

[Amare – Lust Blade]

[Effect: Gains Stunning Touch – 1.5 sec stun on first contact when wielded during active arousal.]

He stared.

Mira raised an eyebrow. "Really?"

Lux coughed. "I’m a Lust. Don’t complain to me."

"Uh huh."

He dismissed the weapons, pleased. "Okay. That’s... that’s actually good. This power set is useful. The drain, the stun, the—"

[Suggestion: Activate True Form – Greed Incarnate]

Lux’s grin widened. "Now that’s what I’m talking about."

He muttered under his breath. "True form activated."

The world tilted.

Heat exploded under his skin.

Dark green light spiraled from his core, wrapping his body like a second skin. Horns lengthened. His hair flared back. His hands flexed, nails sharpening to talon like tips. Gold tattoos burned across his arms, chest, and down his thighs. From behind him, shadowy wings unfurled... no longer the feathery hints of a mid-tier demon.

These were full infernal wings.

Layered. Vast. With sin runes glowing across the membrane like circuit diagrams of want and conquest.

A second pair of horns curled behind the first, forming a twisted crown. His eyes burned gold, slitted like a predator in heat. His voice? Rougher. Deeper.

His aura?

Overwhelming.

A CEO at his highest merger moment.

A demon lord who just remembered he was owed everything.

[Pressure Level: Demonic Lord]

Her thighs clenched.

Her breath caught.

This wasn’t Lux in his teasing mode, or Lux in his sly, smug, CFO-calculating mode.

No, this was something ancient wrapped in that same sinful smile.

Something deeper. Raw. Dominant.

Sira took a step back, chest rising and falling. Her pride instinct screamed ’don’t submit...’ but her body had its own idea.

This wasn’t the Greed Prince anymore.

Not just that.

This was evolution.

This was power.

"Lux?" she whispered, lips parting.
