Hero Hack: Reversing Heroes and Raising Harem

A deep, guttural roar split through the air, shaking the cracked walls of the mansion.

The girls turned sharply, their eyes narrowing.

In the distance, through the broken gate, something massive was moving toward them.

Velra's gaze sharpened. "That's not just some wild beast… that's a devil."

Zelia's expression stayed calm, but her tone was firm. "And judging by its ether signature… It's Supreme rank."

A slow smirk crept onto Zain's face. "Perfect."

He rose from the throne and gestured lazily toward the approaching figure.

"How about you three go have some fun with it?"

Savra arched a brow. "You're giving us permission to play?"

Zain chuckled. "More than that. It's inside my territory now."

"That means it's being suppressed. No matter how strong it is out there, in here it's nothing but prey."

Velra's grin widened, cracking her knuckles. "Then let's see just how much weaker it gets."

Savra's crimson eyes gleamed with excitement. "I'll make sure it burns nice and slow."

Zelia simply adjusted her grip on her blade. "Understood. We'll handle it."

The three of them stepped forward, the air around them already beginning to shimmer with killing intent.

Zain, meanwhile, paid no mind to the approaching devil or the sounds of the girls preparing for battle.

Instead, he leaned back against the throne, closing his eyes for a brief moment as his thoughts shifted to a different goal.

This mansion… It's mine. It always was. But in its current state, it's barely fit to stand.

If I'm going to make this the heart of my Heavenly Demon Sect, I need to rebuild it from the ground up.

He exhaled slowly, his gaze dropping to his hands.

"Too bad my ether's been drained from setting the territory," he muttered under his breath.

A faint grin tugged at the corner of his lips. Thankfully… I have something better than rest, [Heavenly Demon God].

"All I need to do," Zain murmured, "is feed."

He shifted into a meditative posture right there on the throne, spine straight, hands resting loosely on his knees.

Closing his eyes, he began to inhale, not just air, but the raw essence that clung to the core area.

Rotten ether from the cracked walls… lingering traces of corrosive miasma in the air…

Even the faint energy bleed from the approaching devil's footsteps.

Every breath he took turned the corruption into something denser, purer, darker.

Every exhale spread his own Heavenly Demon Ether back into the territory, reinforcing his control.

Slowly, the exhaustion weighing on his limbs began to fade.

His chest rose and fell with a steady rhythm, the aura around him thickening until it became almost visible.

He smirked without opening his eyes. Keep coming… I'll take everything this place has to offer.

The girls moved in unison the moment the hulking figure emerged from the mist.

The Supreme Rank devil's skin was like molten rock, glowing cracks running across its massive frame.

Its eyes burned like twin furnaces as it roared, shaking the fractured walls of the mansion.

But inside Zain's newly claimed territory, it wasn't at full strength.

Its movements felt heavier, slower, its aura dampened by the [Heavenly Demon Sect] suppression.

Velra smirked, cracking her neck. "Perfect. Let's break it down."

She surged forward first, her form vanishing into a blur.

Her leg whipped out in a sharp arc, [Velvet Fang Kick], slamming into the devil's ribs.

The impact forced the beast a step back, black ash spraying from the wound.

Savra followed up instantly, her hands igniting in sacred crimson flame.

[Flame Invocation] burst forth in a rapid volley of fire lances, peppering the devil's chest and forcing it to raise its arms in defense.

Zelia stayed at the edge, eyes locked in cold focus.

She slid her blade free in one smooth motion, ether condensing along the edge.

With a flick, she unleashed [Sword Arc Sever], a crescent of energy that carved a deep line across the devil's thigh, staggering it.

The devil roared, swinging a massive claw toward Velra.

She ducked under it, planting her palm on the ground before spinning.

Her leg whipping upward in a full-circle strike, [Velvet Guillotine Kick], snapping the devil's jaw sideways.

Savra capitalized on the opening, planting a glowing ritual circle beneath its feet, [Sacred Flame Rite].

Pillars of fire erupted upward, engulfing the devil in a cage of divine heat.

The beast thrashed, the suppression preventing it from breaking free instantly.

Zelia darted in, her blade stabbing clean through a glowing crack in its chest.

[Piercing Moon Strike] sent a burst of ether through the wound, making the devil roar in pain as black smoke poured from its mouth.

Still, even suppressed, a Supreme Rank devil wasn't easy prey.

It slammed its foot down, sending a shockwave that knocked all three back.

Velra skidded to a stop, her smile sharper than ever. "Not bad… but not enough."

She dashed back in, ether surging into her legs.

[Velvet Demon Heel Drop] came crashing down like a falling guillotine, shattering part of the devil's shoulder.

The battle wasn't over, but the momentum was shifting fast.

---

Zain could hear the clash of steel, the crack of impact, and the devil's enraged roars echoing outside the hall.

From the rhythm of the sounds and the occasional burst of laughter, Zain could tell the girls were enjoying themselves.

A faint smirk curved his lips. Good… they're having fun. With the weakened supreme devil, they can train a lot.

By now, the steady pull of [Heavenly Demon God] had done its work.

Ether surged through his veins once more, his strength refilling like a tide returning to shore.

He exhaled slowly, opening his eyes. "Not bad… I've got enough to get started."

His gaze swept over the worn beams, cracked walls, and moss-covered floor.

The faded glory of the mansion seemed to stare back at him, almost daring him to restore it.

"Alright," he murmured, flexing his fingers as crimson-black ether began to coil around his hands. "Time to bring this place back to life."
