Harem Startup : The Demon Billionaire is on Vacation-Chapter 672: Mess With Me And I’ll Make You Work For Me

Chapter 672 – Mess With Me And I’ll Make You Work For Me

Lux twirled it once in his fingers. The air stilled. Even the dying Overlord felt it. The way the core seemed to quiver, shuddering like it knew what was coming.

"Yeah," Lux muttered, dragging the back of his hand across his busted mouth. "You feel that? Good. Because we’re about to get very personal."

He stood slowly, his legs trembling for a second from the earlier blow. His ribs still ached. His wings ached. His pride? Not so much.

The pen’s point flared gold as Lux pressed it to the surface of the core. The moment the nib touched it, the realm screamed again, an internal, high-pitched sound that made the air taste like burnt ash and ozone.

Lux began to draw.

He started with the central rune of Greed. The spiral. The hoard loop. It curled outward in perfect symmetry, feeding into itself. Then came the service clause. Then the bonded ring.

Each sigil burned into the Overlord’s core with a hiss and a snap, releasing brief bursts of cursed vapor that coiled around Lux’s ankles.

The Overlord stirred.

"You... you dare," it growled, voice fractured. "You would brand me?"

Lux didn’t stop writing.

"I’d brand your soul if it had market value," he said casually, drawing another hooked line. "Don’t take this personally. You’re a high-risk asset. Too big to kill. Too annoying to let go."

"You cannot enslave what predates time."

Lux clicked the pen and switched ink reservoirs. "Maybe not. But I can acquire it. You’re just a legacy entity with no remaining liquidity. And I?"

He paused and grinned.

"I’m very liquid."

He kept drawing.

More sigils.

These ones were older. Rougher. Written in the handwriting of demonic kings from before the era of Thrones and Rings. Ancient, brutal, and full of arrogance that didn’t care about aesthetics, just power. They wrapped around the core like chains made of symbols and finance clauses, cold and elegant in a way only greed-born contracts could be.

Yeah.

That was a huge level of petty.

And so very Greed demon.

Because Lux wasn’t just binding a soul.

He was forcing an ancient Abyss Overlord to become his servant.

Why?

Simple.

Because killing Zehar would’ve been flashy, sure. But stupid. If he ended this old bastard, more would come. Older ones. Crazier ones. And they’d come not for contracts, but war. Bloodline war. High House eradication kind of war.

No thanks.

Lux didn’t need revenge. He needed compliance.

And obedience.

And a very clear statement to every other ancient watching from the shadowed rings.

"Mess with me and I’ll make you work for me."

He’d had this insane, impossible idea fifty years ago. Watched someone try it and fail. But the failure hadn’t been in the method. It was execution. Patience. Precision. Branding something older than cities took finesse, and absolutely no fear of pissing off half the infernal boardroom.

Now?

He crouched low beside the still-pulsing core. The air buzzed against his skin. His body ached like hell. But his eyes were sharp.

Focused.

He added the final loop.

The runes flared, every last one igniting in sequence. The light blasted upward like a geyser of molten signatures, wrapping the Overlord’s form in fiery contract law.

The creature screamed.

Its body spasmed. Its shadow cloak evaporated like mist. Its bones, what passed for bones, locked in place as if chained by something far worse than steel.

"YOU DARE—"

"I do," Lux cut in. "This is forced acquisition protocol. Clause thirty-three of executive greed doctrine. You knew it was coming."

"You will unleash fury."

"I’ll get ahead of fury. That’s what PR is for."

The runes began to sink into the Overlord’s skin. Every swirl of light branded its incorporeal mass, until the black of its body was layered in gold binding etchings.

The Overlord collapsed forward, arms braced against the floor, breathing ragged.

Lux dropped the pen back into his storage with a click and flicked blood off his hand.

"Congratulations," he said, rolling his sore neck with a satisfied grunt. "You’re the first Abyss Overlord with a Greed compliance stamp."

"Release... me..."

Lux walked closer, crouched, and tilted his head.

"No. But I will give you a new department title."

He reached forward. Touched the branded sigil still burning on the core. And pressed in.

The glow sank.

The core stilled.

And a soft chime echoed in the space.

[System Alert: New Entity Registered]

[Name: Zehar – Abyssal Overlord]

[Status: Bound Servant – Greed Executor Contract Class]

[Obedience: Pending Stabilization]

Lux finally exhaled, his shoulders sagging.

His body was one big bruise. His soul felt like it got drag and dropped through a tax audit. But his smile?

Sharp as hell.

He sat down, legs crossed on the dying floor of the core, breathing in slow through his nose.

Everything was quiet now.

Smoke curled from the ruptured walls. The runes were dim, but not gone. And the Overlord, now silent, remained kneeling, tethered to him by golden lines that stretched across the entire room.

Lux looked around slowly.

Then reached into his pocket and pulled out the Save Point Crystal.

It shimmered faintly.

But he didn’t activate it yet.

No rush.

He wanted this moment.

To sit there, sore, victorious, barely upright, but grinning like the bastard son of Hell he was.

He looked at the Overlord again. Still twitching.

Then he leaned back on one elbow, closed one eye, and sighed.

"Holy Hell," he muttered. "I can’t wait to see Sira’s face when she hears I didn’t kill you."

A low, painful hiss came from the Overlord.

"...you... insane... little—"

Lux raised a finger. "Uh-uh. Servant."

The abyss groaned.

And Lux?

He chuckled.

Then stretched, cracked his neck again, and whispered, "That’ll teach you to drag a CFO into your balance sheet without reading the fine print."

He stood.

"Now," he said, brushing ash from his pants. "Let’s go home before Mira thinks I died in another dimension and Lullaby puts the realm to sleep in mourning."

He tapped the Save Point Crystal once.

[Teleport Initialized – Returning to Anchored Location: Beberly Hills Mansion]

Just before the shift pulled him out, he looked back one last time.

The core.

The wreckage.

The branded Overlord.

His.

All his.

And he smirked.

"Perfect."
