THE ZOMBIE SYSTEM-Chapter 25: Mid-Dungeon Boss: The Flesh Golem

A Monstrous Sight

Leon adjusted his grip on his mana gun, his pulse steady despite the oppressive air around him. The labyrinth had led him here, deeper than he expected, to a vast chamber where the stone walls gleamed with something slick. The room stretched wide, towering columns of flesh-like growths pulsing faintly in the dim red light.

Then, the stench hit him.

Rot. Decay. A thick, cloying odor that clung to his skin. His sorcerer and warrior stood at his sides, silent as ever, but even the undead could feel the wrongness in the air.

Then something moved.

A deep, wet shudder rippled through the chamber. Leon tensed, his gun already aimed toward the far end where a massive shape loomed in the shadows. A grotesque figure, stitched together from countless corpses, shifted forward.

The monster's arms were mismatched—one thick and bulging with necrotic muscle, the other eerily thin but tipped with elongated claws. Its body was a patchwork of decaying flesh, stitched by an unnatural force.

Then its head turned toward him.

The thing had no eyes.

But it saw him.

A low, gurgling growl rumbled from its throat, followed by a sickening snap as its massive jaw unhinged.

The system's warning appeared in Leon's mind.

[System Alert: Mid-Dungeon Boss Encounter – The Flesh Golem]

Threat Level: Deadly

Leon exhaled.

"So that's what I'm dealing with."

First Strike

The Flesh Golem lunged.

Leon fired. A mana-infused round shot straight into its chest, tearing through rotten muscle, but the thing didn't even flinch.

The next second, the monster was on him.

Leon barely dodged to the side as the massive arm swung down, slamming into the stone where he had been standing. The impact shook the entire chamber, sending dust and loose debris falling from the ceiling.

His warrior zombie moved first, charging forward with its massive cleaver. The blade bit deep into the golem's left leg, slicing through flesh—only for the wound to immediately seal itself.

Leon's eyes flickered. Regeneration. Of course.

The golem turned its attention to the warrior, swinging its clawed arm like a whip. The razor-sharp talons tore straight through his summon's torso, splitting it in half.

Leon didn't panic. He simply snapped his fingers.

"Reconstruct."

Dark energy rippled through the air, and his warrior reformed beside him, whole again. The golem paused, as if confused. It hadn't expected that.

Neither had Leon expected what came next.

The Flesh Golem opened its mouth wider than should have been possible. From within its throat, a twisting mass of tendrils shot out, writhing toward him like hungry snakes.

Leon fired again, his gun glowing with dark energy, and the moment the mana bullet hit the tendrils, they withered and burned.

A guttural scream erupted from the golem.

He narrowed his eyes.

So it could regenerate its body.

But not its soul.

A Shift in Strategy

Leon raised his hand. "Sorcerer. Soulfire."

His sorcerer lifted its skeletal arms, a green inferno swirling between its fingers. The fire crackled unnaturally, casting twisting shadows across the chamber walls.

The Flesh Golem let out another deep, unearthly moan as if recognizing the true threat.

Then it charged.

Leon fired a shot to slow it down, but the monster didn't stop. It barreled through his warrior zombie, sending the summon crashing into the far wall, then swung at the sorcerer with its massive, misshapen fist.

The undead barely teleported away in time, reappearing on the other side of the chamber.

But Leon knew he couldn't keep dodging forever.

So he didn't.

Instead, he stepped forward.

Ending the Fight

Leon let out a slow breath, reaching into his coat. He pulled out a single, modified mana cartridge, the markings along its casing glowing ominously.

He loaded it into his gun.

The Flesh Golem, sensing something, let out a horrible wail and charged again.

Leon stood his ground.

He fired.

The moment the bullet left the barrel, the entire room dimmed.

The shot wasn't just physical. The modified cartridge carried pure necrotic energy, the essence of death itself.

The bullet punched into the golem's chest, sinking deep into the mass of rotting flesh. Unlike his previous shots, this one didn't just tear through it.

It unmade it.

The energy spread outward like veins of darkness, crawling across the golem's body. Its regeneration kicked in—desperately trying to stitch itself back together—but the corruption was faster.

The monster let out a horrible, choking shriek, its body writhing as black cracks spread over its form.

Leon simply watched.

With one final, shuddering convulsion, the Flesh Golem collapsed into itself—

And then it was gone.

The chamber fell silent.

Leon lowered his gun.

Aftermath

The system's notification appeared.

Leon exhaled, rolling his shoulders. He could already feel the fatigue setting in, but he wasn't done yet.

His eyes shifted toward the far end of the chamber, where a single path stretched deeper into the labyrinth.

The real enemy was still ahead.

And now, he knew this dungeon wasn't just an ordinary challenge.

Something was waiting for him.

Something intelligent.

Leon adjusted his grip on his weapon and stepped forward.
