Reincarnated as the Demon King's Son

Aldred approached the demon-infested planet with a calmness that belied the gravity of his mission. Hundreds of demonic vessels swarmed the atmosphere, a protective barrier of sheer force and malevolence. Yet, they passed over Aldred without a flicker of recognition, as if he were nothing more than a whisper against the backdrop of space.

It was not invisibility that shielded him but a far subtler magic, one that clouded perception and diverted attention. He moved among them, unseen and unchallenged, a ghost drifting towards his quarry.

From orbit, the planet revealed itself as a hive of demonic activity. Massive forges belched fire into the sky, their flames casting an infernal glow over sprawling cities. Legions of demons moved in chaotic harmony, their forms diverse and horrifying, engaged in ceaseless labor or brutal training for wars yet to come.

Towering spires pierced the sky, from which the dark energies pulsed, weaving a tapestry of power that shielded the planet from prying eyes and unwelcome intruders.

Aldred hovered in space, his gaze piercing the veil of demonic might. His eyes, glowing with a light born of ancient power, observed the ceaseless industry, the relentless preparation for conquest. It was a world of darkness, yes, but also of undeniable strength and purpose.

"It's almost beautiful, in a terrifying sort of way," Aldred murmured to himself, the weight of his task pressing upon him. He knew what had to be done, yet the sight of a world so alive with activity, so vibrant in its dark majesty, gave him pause.

Drawing a deep breath, Aldred extended his hands, palms facing the planet below. The fabric of reality seemed to bend and warp around him, a visible distortion in the space between his fingertips and the world he targeted. Then, with a forceful downward motion, he unleashed his power.

The effect was immediate and catastrophic.

A palpable wave of energy, invisible to the eye but overwhelming in its might, swept across the planet. The ground shuddered and groaned as if in agony, vast fissures tearing through cities and wilderness alike.

Demons looked up in shock and terror as the very world beneath their feet betrayed them, gravity itself turning malevolent. Structures that had stood for eons crumbled in moments, swallowed by the gaping maw of the planet as it fractured under the assault.

Aldred watched, his expression a mix of sorrow and resolve. "This is the price," he whispered, not to anyone but to the cosmos itself. "The price of your aggression, of your hunger for conquest. May this be a lesson to those who would follow in your footsteps."

They stood no chance under his might.

Aldred's journey through the cosmos became a silent vigil, a lone warrior moving against the dark tide that threatened to engulf the universe. Each demon world he encountered was a testament to the relentless ambition of its inhabitants, a mirror to their desire for dominion and power.

And yet, with every planet he visited, Aldred brought with him a reckoning, a force of nature that could not be denied or deflected.

On the world of Zharak, where the skies were choked with the fumes of industry and the rivers ran thick with the blood of the enslaved, Aldred found no beauty, only desolation. Here, the demons had built their empire on the backs of countless conquered peoples, their suffering the foundation of demonic might.

As he orbited above, Aldred's heart grew heavy with the weight of the pain that emanated from the surface.

"This cannot stand," he declared, his voice a whisper that carried the force of thunder. With a gesture, he summoned a storm of cosmic energy, directing it towards the planet's core. As the storm penetrated the surface, it ignited the volatile compounds that powered the demonic machines, setting off a chain reaction that tore the world apart from within.

The explosion was a brilliant flare in the darkness, a brief but potent reminder of the price of tyranny.

Aldred did not linger to watch the destruction. There were more worlds, more battles to be fought.

His next target was the oceanic planet of Nal'Shara, a jewel of water and ice, twisted into a fortress of sorcery and shadow. Here, the demons had harnessed the ancient leviathans of the deep, binding them to their will and corrupting their once-noble spirits. Aldred felt a pang of sorrow for these creatures, their majesty perverted into tools of war.

As he descended into the atmosphere, Aldred extended his hands, his powers reaching out to touch the minds of the leviathans. "Be free," he urged them, his voice a beacon of light in the oppressive gloom. Under his guidance, the leviathans rose, their rage and pain transformed into a force for liberation.

They turned against their captors, shattering the chains of dark magic that held them, and in their fury, they tore the demonic fortresses asunder.

The planet shook with their wrath, the sea reclaiming what had been stolen.

Dozens then hundreds of worlds fell.

However, the more he destroy these worlds, the more risk he took.

The enemies would soon got a better understanding of his power.

It might not seem obvious, but what Aldred did actually put him in a disadvantage.

He knew nothing about Malgorth's power, but they do know about him.

Aldred knew the risk, but he had to do it.

In the hidden depths of the universe, far from the prying eyes of gods and mortals alike, Zagrath, the Flame Warden, observed the destruction wrought by Aldred with a mixture of fascination and concern. His lair, a fortress of shadow and fire nestled in the heart of a dying star, thrummed with dark energy.

The walls, adorned with ancient runes, pulsed softly, illuminating the vast chamber with a sinister glow.

Surrounded by a multitude of screens, each one a window to a world under siege, Zagrath watched as Aldred moved from one planet to the next, his power unleashed with devastating effect. The Warden's fingers danced across the surfaces of arcane instruments, tracking the path of destruction, calculating the impact on the delicate balance of the cosmos.

"So, he dares to challenge the might of the infernal realms," Zagrath murmured, his voice a deep rumble that echoed through the chamber. "Foolhardy, yet… impressive."

With a flick of his wrist, Zagrath zoomed in on a particular screen, capturing the moment Aldred's power shattered the defenses of a demon stronghold. The Warden's eyes, burning with an inner flame, reflected the cataclysm unfolding before him.

"He wields ancient magics," Zagrath noted, stroking his chin thoughtfully. "Magics that have not been seen in the universe for eons. Interesting."

Despite the danger Aldred posed to his own kind, Zagrath could not help but admire the warrior's resolve. It was a rare sight to see someone so willingly walk into the maw of darkness, wielding light as a weapon against overwhelming odds.

But admiration did not cloud Zagrath's judgment.

He understood better than most the stakes of this conflict.

The balance of power was shifting, and if Aldred's crusade went unchecked, it could lead to a cataclysm far greater than the destruction of a few demon worlds.

"Let me test his strength."

Aldred floated in the void of space, his gaze fixed on the planet below him, now a roiling inferno of flame and lava. What had once been a bastion of demonic power lay broken, its destruction complete. The air, though absent in the vacuum of space, seemed to shudder with the heat emanating from the dying world.

As he turned to depart, the fabric of space itself seemed to warp and shiver. Dozens of massive red portals tore open the cosmos, framing Aldred in a circle of impending doom. From these gaping maws of dark energy, huge demonic leviathans emerged, their bodies writhing masses of scales, claws, and fangs, eyes alight with hellfire.

They were ancient creatures of destruction, pulled from the depths of demonic lore, each one a harbinger of death.

Aldred's stance shifted, his calm demeanor giving way to alert readiness. "So, it comes to this," he said, a spark of resolve igniting in his eyes.

The leviathans charged, their forms cutting through the vacuum with supernatural speed, a nightmare made flesh aimed directly at Aldred. Their roars, silent in the vacuum of space, reverberated through the magical essence that bound the universe together, a primal challenge that no warrior could ignore.

The first leviathan reached him, a colossal beast whose jaws could swallow worlds. Aldred met its charge with a surge of power, a brilliant lance of pure energy that pierced the creature's heart. It recoiled, a silent scream of agony and rage as the light consumed it, reducing it to ash that drifted into the void.

One by one, the leviathans came, and one by one, they fell.

Aldred moved with a grace and power that belied his mortal form, each movement a dance of destruction against the forces of darkness.

Yet, for every beast he felled, two more seemed to take its place, an endless tide of malice.
