Damn, I Have to Marry the Strongest Antagonist at the Start?

Sensing Owen's terrifying power, the Dark Lord's expression shifted dramatically. Just as he prepared to act, he caught sight of Owen's icy gaze locking onto him.

Owen's eyes were devoid of emotion, a chilling void.

Before the Dark Lord could react, Owen's fist, radiating an overwhelming magical aura, loomed large in his vision.

Heaven Emperor Fist!

As Owen unleashed this strike, the Dark Lord's view was stripped of all else. All that remained was the image of the fist expanding relentlessly, exuding an unstoppable force.

Boom!

The fist's impact shattered the stars, causing the heavens and earth to tremble. Endless darkness was obliterated, reduced to fragments that scattered in every direction.

The Dark Lord's body, caught in the blast, was sent hurtling backward through the shattered void. The terrifying force of the strike left cracks spreading across his form, as if he might shatter entirely at any moment.

Owen seized the moment, advancing with Flame Sword in hand, determined to end the Dark Lord.

The burly youth and the bald elder, seeing this, immediately acted. Both surged forward to protect the Dark Lord, unleashing their most potent spells to intercept Owen.

"Star Shatter!"

"Annihilation Ray!"

The burly youth swung his blade, drawing endless mana from the starry expanse into his weapon, forming a terrifying rift.

Simultaneously, the elder's forehead split open, revealing an eerie, glowing eye that fired a devastating ray of light.

"Owen, do you think we don't exist?"

"Without your reinforcements, let's see how long you last today!"

Their roars echoed as they attacked.

Yet, facing their onslaught, Owen remained calm. Gripping the Godslayer Staff, he unleashed a radiant beam of light that met their combined attacks head-on.

Boom!

As their powers collided, the black sea below seemed to evaporate under the resulting shockwaves. The entire base of the Demon Abyss trembled, as though on the verge of collapse.

Amid the chaos, Owen stood tall, an unyielding monument in the storm of destruction.

At that moment, everyone present felt it—the sense that Owen had become an invincible force.

This overwhelming aura was something they had only ever felt from Tsukihime and Leslie before.

Owen's power seemed to have transformed again.

As Owen's enemies, Dolores, the Dark Lord, and their allies sensed this shift most acutely. From Owen, they felt the unmistakable scent of death.

For beings like them—Primordial Gods, who were nearly immortal and incredibly resilient—the idea of true annihilation was almost unthinkable. Even grievous injuries could be healed swiftly.

But Owen's presence now carried the undeniable threat of obliteration.

This was no mere intuition; it was a bone-deep premonition shared by these battle-hardened beings.

And they knew it meant one thing: Owen now had a way to destroy them completely.

As this realization gripped them, a notification flashed before Owen's eyes.

"Heart of King Activated."

Upon seeing this system prompt, Owen felt a profound transformation within himself. His spirit, mana, and very essence seemed to ascend to a new level.

It was as though his once-ordinary magic had been reforged into unbreakable steel, amplifying his power across all dimensions.

"So, this is the Heart of King? Truly terrifying… A masterpiece of the system," Owen murmured.

The Heart of King was a reward Owen had earned after restoring the infernal realm, though he hadn't fully explored or activated it until now.

Now that he had, the benefits were immense.

Previously, he had been confident in wounding the Dark Lord and his allies. But with the Heart of King, he was certain he could annihilate them outright.

Ordinarily, he might inflict severe damage, but their rapid regenerative capabilities would prolong the fight indefinitely. Now, he had the means to break this stalemate.

In that moment, Owen's heart appeared to glow golden in Dolores and her allies' eyes. With each beat, a resounding pulse echoed through the air, leaving their minds reeling.

The sudden shift in Owen's aura clearly stemmed from his transformed heart.

Realizing this, the burly youth and the bald elder refused to give Owen another chance to act. Roaring in fury, they charged at him from both sides.

But Owen merely smirked coldly.

"I've entertained you long enough. It ends now!"

Taking a deep breath, Owen faced the two Primordial Gods without a hint of fear.

Even before activating the Heart of King, he hadn't been intimidated. Now, with his power surging and his spirit emboldened like a true king, he felt utterly unstoppable.

As the others watched, convinced a life-or-death clash was imminent, a profound, ancient heartbeat emanated from Owen's chest.

The golden pulse rippled outward, freezing time and space like a shimmering golden tide.

The charging figures of the two Primordial Gods halted mid-air, frozen like statues.

Though they had sensed the danger an instant earlier, they were too late. The golden wave had already enveloped them, plunging them into a realm where time stood still.

Owen moved deliberately, raising his blade to strike.

Two swift slashes, understated yet precise, severed their frozen forms.

As the golden waves ebbed, their bodies crumbled into fragments, shattered by the lingering mana in their wounds.

The once-radiant golden domain was now tainted crimson with their blood.

From their remains, two spectral forms—souls—emerged, desperately attempting to flee the golden field of the Heart of King.

Though losing their bodies would weaken them, survival and future retaliation were still possible.

Owen shook his head as he watched their futile efforts.

"The moment you chose to attack me, your deaths were sealed."

Their spectral forms trembled.

They knew Owen was no stranger to delivering on his threats.

As they scrambled to escape, Owen's sword struck once more, obliterating their souls entirely.

With their demise, the skies above the Demon Abyss darkened, blood-red clouds gathering ominously.

From these clouds, a rain of crimson droplets began to fall—a celestial phenomenon marking the fall of Primordial Gods.

Two at once, no less.

The onlookers, from Dolores to the Chief, were utterly horrified.

For them, Primordial Gods were insurmountable entities.

Yet, before their very eyes, two such beings had perished at Owen's hands.

"Time manipulation? What kind of power is this? Even The Celestial cannot achieve this!"

"This Owen… His capabilities are beyond belief. To think he still had such a trump card…"

The Dark Lord's gaze fixed on Owen, his heart filled with shock and dread.

But then a thought struck him, and he charged at Owen.

Though Owen's technique had been devastating, the Dark Lord believed it must have come at a cost. Surely, Owen couldn't use it again.

Burning his mana reserves, the Dark Lord prepared to stake everything on one final assault.

Owen, his attention already on the Dark Lord, steadied himself.
