Harem Startup : The Demon Billionaire is on Vacation

Chapter 778 – The Ancestral Incubus Chamber

Lux stiffened. "Okay." His voice sounded smaller than usual. "That’s... strong."

Asmo stepped beside him calmly, unaffected.

Lux swallowed.

He could feel it.

There were no personalities in the air.

No single presence.

Just layers.

Ancient ones.

The Lust Lords who ruled before Asmo.

Before the current houses.

Before recorded infernal economy.

And deeper...

Something else.

The Original Lust.

Not a demon.

Not a lord.

The Sin itself.

It hummed through the chamber like a pulse.

Then...

The air shifted.

The chamber darkened slightly.

And voices began.

Not from one direction.

Not from everywhere.

From within the walls. 𝒻𝓇𝑒𝘦𝘸𝑒𝒷𝓃ℴ𝑣𝘦𝑙.𝒸ℴ𝘮

Within the floor.

Within the air itself.

"...A Lust..."

"...He reeks..."

"...Greed..."

Lux stood still.

Asmo crossed his arms, watching calmly.

Lux muttered quietly, "This is why I do not enjoy heritage ceremonies."

The voices grew clearer.

"Who wakes us?"

"Who disturbs the domain?"

"That Lord?"

A pause.

"...No."

"...Not him."

"...The other."

Lux stiffened slightly.

Asmo grinned. "Don’t mind them. They’re cranky."

The air pulsed again.

"He carries Lust..."

"...But not pure..."

"...He reeks of coins..."

"...Greed."

Lux sighed. "Yes." He spoke clearly now. "I am Greed."

The chamber vibrated slightly.

"And Lust."

Lux exhaled. "...Apparently."

Asmo chuckled quietly.

The voices overlapped.

"Who are you?"

"State lineage."

"Declare blood."

Lux straightened his coat slightly out of reflex. "Lux Vaelthorn."

The chamber echoed the name.

"...Vaelthorn..."

"...Greed line..."

"...Yet..."

"...Lust awakened..."

The pressure increased.

Lux felt it pressing against his ribs.

His sigils flared instinctively.

Green and pink intertwined across his chest.

The system flashed.

[Dual-Sin Resonance Detected.]

[Ancestral Compatibility Scan: 73%...]

Asmo leaned closer to Lux. "Breathe."

Lux did.

The chamber hummed.

"He woke us."

"Yes."

"...The greed boy."

"Not pure."

"...But strong."

"Stronger than the others."

Lux narrowed his eyes slightly. "Others?"

Asmo whispered, "Past heirs."

Lux inhaled slowly.

One of the voices sharpened.

"You reek of restraint."

Lux blinked. "...Excuse me?"

"You bind Lust."

Lux frowned. "I practice control."

A ripple of ancient laughter moved through the chamber.

"Control."

"Control."

"He starves himself."

Lux’s eye twitched. "That is called discipline."

Another voice, deeper, older...

"...Why wake us?"

Lux opened his mouth.

Paused.

Closed it.

Asmo leaned back against the invisible pressure, amused. "Well?"

Lux exhaled slowly. "I didn’t wake you intentionally."

Silence.

"...Then why?"

Lux hesitated. "...Emotional stress."

The chamber went quiet.

Asmo tried not to laugh.

Lux glared at him. "I had a difficult day."

The voices shifted.

"He broke restraint."

"Yes."

"He surrendered."

"Finally."

Lux frowned. "I did not surrender."

The pressure intensified. "You unleashed."

Lux inhaled sharply as his sigils flared brighter.

[Ancestral Resonance: 89%...]

Asmo raised an eyebrow.

"Oh?"

The chamber’s voice deepened.

"You are Lust."

Lux swallowed. "I am Greed."

"You are both."

The pressure surged.

Lux’s aura burst outward instinctively.

Green and pink spiraled around him.

The chamber trembled.

"He holds coins."

"Yes."

"But he burns."

"He burns bright."

Lux clenched his jaw. "I am not here to replace anyone."

Silence.

"...Not yet."

Lux blinked. "...Not yet?"

Asmo laughed softly. "Oh this is getting good."

Lux shot him a look. "Do not encourage them."

The chamber pulsed again.

"Greed boy."

Lux stiffened.

"Yes."

"Why bind yourself?"

Lux’s expression hardened. "Because without control, Lust destroys."

The chamber responded instantly.

"...And Greed does not?"

Lux paused.

Asmo slowly smiled.

The ancient voices whispered again.

"You are afraid."

Lux inhaled slowly. "...No."

"Curious."

Lux blinked. "...Yes."

The chamber softened slightly.

A deeper presence rose from beneath the others.

Older.

Colder.

More primal.

The Original Lust.

Not seductive.

Not playful.

Raw desire.

It spoke only once.

"Balance."

The word echoed through the chamber like a command.

Lux felt something inside his chest shift.

Not violently.

But clearly.

The system flared.

[Dual-Sin Equilibrium Acknowledged.]

[Ancestral Domain Stabilized.]

[Permission Granted.]

The pressure eased.

Not gone.

But no longer suffocating.

The voices softened.

"He is Lust."

"Yes."

"...A full Lust."

"...Though Greed stains him."

Lux folded his arms slowly. "Greed does not stain."

For a moment, the chamber seemed to accept the statement.

Then the air changed.

Not louder.

Not brighter.

Heavier.

The kind of pressure that made bones remember gravity.

Lux felt it first in his ribs. Then in his spine. Then in the invisible weight pressing down on his shoulders like an ocean.

The sigils across the chamber ignited again.

Not crimson this time.

Black.

Ancient.

The system flickered violently.

[Warning: Primordial Presence Manifesting.]

[Domain Authority Overridden.]

[Ancestral Layer: Primordial Sin]

Lux froze.

Beside him... Asmo stopped smiling.

That alone was enough to tell Lux this had escalated past the usual heritage theatrics.

The chamber darkened.

Shadows thickened into something almost liquid.

And from the center of that darkness...

A form emerged.

Not fully.

Not clearly.

Just a silhouette made of gravity and hunger.

The Primordial Sin of Lust.

It did not sit on a throne.

It did not glow.

It simply existed.

And that existence alone forced both Lux and Asmo down.

Their knees hit the stone floor at the same time.

Not by choice.

By law.

Lux’s breath left his lungs.

He had been in divine negotiations.

He had faced celestial courts.

He had stared down infernal kings.

None of those felt like this.

This was older.

Rawer.

Like standing in front of a law written before Hell itself learned how to govern.

The shadow moved.

Slowly.

It circled Lux.

Not walking.

Flowing.

Like smoke observing prey.

Lux straightened his back slightly despite the pressure.

Lobbying mode.

If this was a court... Then he knew how to survive courts.

The shadow’s voice arrived not through sound but through sensation.

"You hold Lust. And Greed. An anomaly."

Lux exhaled through his nose. "...That word comes up a lot lately."

The shadow continued circling him.

It was studying him.

Testing.

Feeling the aura spiraling through his body.

The chamber whispered with ancient voices again.

"Greed and Lust."

"Strange combination."

"Rare."

"Dangerous."

The shadow stopped in front of him. "Why?"

One word.

Simple.

Heavy.

Lux didn’t answer immediately.

He inhaled slowly.

The pressure pushed harder, like the question itself had weight.

Why?

Why hold Lust after starving it for centuries?

Why deny it?

Why unleash it now?
