Harem Startup : The Demon Billionaire is on Vacation-Chapter 675: Black Jello

Chapter 675 – Black Jello

The little slime pulsed once on his shoulder, letting out a low, disgruntled pu. Not the cute kind. The ’I’ll destroy your bloodline when I recover’ kind. But with his core still cracked and runes still faintly glowing on his black jello like surface, the only thing Zehar could really do was vibrate and glare.

Which he did.

Impressively.

"Yeah, yeah," Lux muttered, walking toward the kitchen island. "I know that look. Believe me, I’ve worn it before."

Lux strolled casually toward the kitchen. The overhead lights flicked on with a hum as he passed beneath them, casting his long silhouette over the sleek counter. Weirdly, he found no servants nor Lyra.

He opened the sleek black coffee machine, lazily shoving a capsule in with one hand while the other dipped into the air behind him, pulling from thin space like reaching into a VIP vault. A ripple in the air shimmered gold. From his dimensional storage, he pulled out a small red bottle, sealed with gold twine and tagged with a curl of demonic shorthand.

[Infernal Elixir—Grade A].

The moment he popped the seal, a soft pulse of warmth brushed against his skin. Not heat, luxury. This wasn’t your average healing potion. This was one of his CFO-tier craft elixirs, designed to restore HP, stamina, and get you hard enough to punch a god if needed.

"Morning meds," he muttered to himself with a smirk, pouring it down in one clean swallow while the coffee machine hissed behind him. The elixir hit like a perfect espresso shot laced with dark mana, flooding his limbs with warmth and shivering fire.

[Dark Healing Actived]

[Regeneration: Passive Triggered]

[HP Restored: 100%]

And yeah, he could’ve stayed cool and let the system do the rest. But why not enjoy both? The taste of sin and espresso made mornings worth waking up for.

His spine cracked back into place, and his wings twitched as if remembering how to behave. Lux rolled his neck, finally standing straight again without gritting his teeth.

Meanwhile, the slime watched with narrowed, judgmental eyes.

Lux snorted.

"Don’t look at me like that." He reached back into the storage and pulled out a second bottle. "Here."

He held it up toward Zehar, who didn’t move.

Corvus immediately launched off the back of the couch, flapping once and landing near Lux with a pointed screech. "You’re giving him an elixir? Seriously?"

Lux popped the cork and offered it anyway. "I don’t want my new servant dying in the first quarter. Bad for image."

Corvus gawked. "Image? He tried to vaporize you."

"He missed," Lux said, matter-of-fact.

Zehar didn’t reach for the bottle. Because, you know, no hands.

Lux tilted his head. "You gonna float down or what?"

The slime made a noise that sounded like a sigh, hovered in place, then lunged at the vial, swallowed it whole, glass and all.

Corvus shrieked. "He ATE the bottle!"

Lux blinked. "Huh. Neat."

Zehar purred. Not gently. More like a low engine revving. His surface shimmered. The cursed sigils around his gooey outline dulled slightly.

He wasn’t healed yet. But he wasn’t dying either.

"See?" Lux said, tossing the empty cork over his shoulder. "One step closer to a fully functioning apocalypse pet."

Lullaby stepped out from the hallway, rubbing one eye. Still barefoot, with that signature ’I just woke up but will end you’ aura. She padded across the floor and stood right in front of Lux.

She looked at Zehar. Then at Lux.

Then back at Zehar.

She scowled.

"I still don’t trust him."

"You shouldn’t," Lux replied without missing a beat. "But he’s branded and broken. Plus, I own his soul now. So, you know, team-building."

Lullaby huffed.

Then reached up.

And patted his head.

"Good Lux," she said softly.

His smirk softened a fraction. "Don’t patronize me."

Corvus, from the floor, coughed. "Too late."

Lux ignored him. "Now then—Lulla, are you going back to sleep or...?"

"Yeah," she mumbled, voice low and floaty. "But after I cancel my sleeping spells."

Lux froze mid-step.

He turned slowly. "You what."

Lullaby looked at him with a sleepy blink. "I put sleep spells on everyone. Just in case."

"Everyone?"

She nodded. "The staff, the girls. It was... a security measure."

Corvus turned toward her, horrified. "That’s why no one woke up when the Overlord showed up?!"

She nodded again.

Lux walked over to the nearest window and peeked out toward the courtyard. Sure enough. Half a dozen servants were slumped against pillars. Mira? Still curled on the upstairs lounge, hair a mess, snoring softly like a cute Eastern dragon in deep REM.

He looked at the living room clock.

It blinked 09:17.

Lux groaned.

"You better cancel it now."

Lullaby tilted her head, confused. "Why?"

He pointed toward the hallway with the dramatic flair of someone reciting doomsday prophecy.

"Because they are going to be late for work."

Lullaby blinked again.

"Oh."

She raised a hand lazily, snapped her fingers, and the air shimmered like a screen saver snapping off.

Immediately, the distant sound of people screaming in confusion echoed from various rooms.

Someone tripped over a sofa.

A toilet flushed aggressively.

Naomi yelled, "PAST 9?! I’M DOOMED!"

Mira’s voice followed a second later. "LUX, WHERE ARE YOU, I HAD A DREAM YOU DIED—"

Lux sighed into his hand. "So much for a quiet morning."

Corvus perched on the couch, fluffing his wings. "You could’ve died. Instead, you brought home a slime and overslept an entire building."

Zehar let out a long, angry pu.

Lux tapped the slime with one finger. "Don’t ’Pu!’ me. You’re going to love HR."

Lullaby yawned beside him, resting her head lightly against his shoulder.

"I’m going back to sleep," she murmured.

"You just woke up," Corvus said.

She didn’t reply.

She was already snoring.

Lux reached for his coffee machine, voice dry. "Remind me to file an overtime form for surviving eldritch mergers. This counts as billable trauma."

Just like that... The mansion woke up in chaos.
