Seven Sins System Chapter 613. A Test Run?

Seven Sins System Chapter 613. A Test Run?

I teleported straight to his office, a place even high-ranking warlords avoided unless summoned.

-Pop!

I landed inside his office. The usual magical barrier pulsed—recognizing my bloodline—and allowed me through with a single shimmer.

Weird.

There was no sound.

No music. No giggles. No suspicious succubus moans from the corner couch. Not even the deep, throaty laughter my father was known for when f*cking one of them… or some of them.

The office was empty.

Dead quiet.

My fingers flexed slightly as I scanned the room, instincts flaring. The desk was there—still messy, still full of scattered documents, open scrolls, dark feathers from one of his ravens—and the laptop he only half-understood was humming softly on its stand.

But no one was in the chair.

“…What?”

This didn’t make sense.

My father was many things—lazy definitely one of them. But he usually did everything from this office. As long as I was stationed in the mortal realm, he rarely left it unattended, and never without locking the damn thing down.

The wards here weren’t trivial. Only a few could bypass them: me, my sister, and three of his most trusted aides. Everyone else? Needed blood clearance or a formal request.

And yet… no trace of him. Not even a flicker of residual aura.

Cautiously, I moved toward his desk. My fingers brushed over a few of the scrolls, mostly field reports. One was a letter, sealed with golden wax from the Light Realm. I flipped it open and read.

My breath caught at the signature.

The Queen of the Light Realm.

Puriel’s mother.

It was a diplomatic report—a complaint, on the surface—but beneath the formal tone, it was clear they’d been talking. She mentioned incidents: unauthorized demons bypassing the veil into mortal space… and even worse, similar crossings into her realm.

Her words were careful, but this one line stood out.

“Your earlier theory appears to be correct. There is a third force. One neither wholly of shadow nor wholly of light. Something that feeds on the breach itself.”

I stared.

So he knew.

He knew something was manipulating the balance.

And instead of acting, he’d been waiting. Watching.

Playing dumb.

My fingers slowly curled into fists over the parchment.

“So you knew all along,” I muttered under my breath. “And you just let us play right into it.”

I sat down in his chair—the throne-like one with jagged steel arms and a corrupted velvet backrest—and leaned back. The crystal core on the desk flickered with a system interface, awaiting input.

But I didn’t touch it.

I just stared at the letter.

Thoughts spinning.

If my father and her mother were both aware… what did that mean? Were we the bait? A test run? A key?

And if that scent in the cave really was from the Love Goddess’s palace, buried beneath the Lust domain… then maybe someone had already opened a door that was supposed to stay shut.

A door that linked love, lust, and fate in ways that hadn’t existed since before the war.

“Who are you?” I whispered to the empty air.

Not to my father.

Not to the queen.

But to the hidden hand that had stirred this mess from the shadows.

The one threading goddesses and devils together for a plan we hadn’t even seen the edge of yet.

I stared down at the faint glow on my wrist—the thread still linking me to her.

Puriel.

We were never meant to work.

But here we were.

And somehow, I had a feeling this wasn’t just about balance or realms anymore.

This was about rewriting the entire game board.

And someone out there was already a move ahead.

I leaned back in Dad’s throne-chair, still staring at that damn glowing thread like it held answers I couldn’t read yet.

I needed answers.

I didn’t just want them anymore—I needed them like a demon needs wrath, like a warlock needs mana, like a devil prince who just might’ve triggered a cosmic event needs an explanation now.

Without standing, I teleported again.

I landed inside my father’s bedchamber. Dimly lit. Velvet drapes. Gold-accented furniture. Not a pillow out of place.

The bed? Neatly arranged. Crisp sheets. No signs of use. No half-dressed succubi. No teasing laughter.

I blinked. “…What the hell.”

If he wasn’t in the office or in bed, then—

Throne room.

Of course.

I didn’t waste time.

‘Teleport.’

The air shifted sharply, shadows wrapping around me as I emerged near the rear end of the throne hall, just behind one of the obsidian pillars.

And that’s when I heard it—voices.

Low.

Sharp.

And serious.

Which immediately made me stop moving.

Because my father, Diablo—The Demon King—was never serious. He laughed in battles. He used executive reports as placemats for wine goblets.

But now?

His tone was cold. Controlled. Focused.

Something was wrong.

I didn’t step out. I didn’t announce myself.

I just stood there, behind the pillar, like a spy in my own house.

He probably knew I was there—he always did—but he didn’t say anything. Which meant he didn’t want to break the flow. So I listened.

His aide, Rathor, probably—spoke first. His voice always had that constant undertone of growl.

“It wasn’t just a surge. It was a ripple,” Rathor said. “Like a tear brushed the realm’s skin. It passed through ours, the mortal plane, and… even the Light Realm.”

Diablo was silent for a moment.

Then… “I felt it too. Subtle. But it was there. Like a heartbeat in a tomb.”

Veras, the mind-warden—spoke next, calm and analytical. “The frequency wasn’t raw demonic or holy. It was balanced. Filtered. Interlocked. A dual resonance.”

I blinked. My pulse slowed.

‘Oh, shit.’

“Any location trace?” Diablo asked.

“Somewhere around the mortal midpoint,” Veras replied.

I could almost hear my father’s jaw tighten.

“It wasn’t big,” he said slowly. “Not enough to shatter planes. But it was new. And that makes it dangerous.”

I pressed my lips together, fingers twitching at my sides.

Yeah.

No doubt about it.

That was us.

Me.

And Puriel.

Having sex.

Cosmic, divine-demonic, reality-ripping sex that apparently sent a magical ripple across three damn realms.
