Born as the fourth son of the Heavenly Demon Sect's supreme leader, Jin Seo-Won was shunned and humiliated simply because his mother came from the commoners, not from the prestigious Seven Clans that uphold the sect.

Betrayed by his own brothers and silently executed by the heir of the Sword Clan, Jin Seo-Won's life ended in despair.

But fate wasn't done with him.

A mysterious system gave him a chance to return to the past—before his mother's death, before his fall. Now armed with future knowledge, hidden power, and cold determination, he walks the path of revenge through blood and flame.

He will challenge the pride of the Seven Clans.
He will tear down the thrones of his brothers.
And this time... he will rise not as a discarded son, but as the true heir of the Heavenly Demon Sect.

Let the world tremble.

He has returned.

Heavenly Demon Regressor

> "ALERT! Defensive formation! They're coming from three directions!"

The instructor's voice echoed across the valley—but it was already too late.

Elite mercenaries from outlaw clans, remnants of an old rebellion, surged into the camp. They came like a black tide—hundreds of them.

Screams ripped through the darkness.

In the center of chaos… stood one figure, unmoving.

His robe fluttered in the storm of violence. His long black hair began to tint blood-red at the tips. A wicked aura started to pulse from his body.

> "Do-Yoon. Soo-Ran," he said quietly.

Without waiting, he leapt into the air—spinning midair, his blade drawing a perfect arc that split three enemies apart in one motion. Blood rained like mist.

> "Demonic Shadow Step – Level Four."

He vanished—reappearing behind the main strike group of enemies. In one sweeping strike, he cut down ten men.

> "There! It's him—the Fourth Prince!"

Poison needles, shadow spells, and blood magic surged toward him—

—but the aura around Seo-Won burned it all away.

> "You think your filth can touch me?"

> "SYSTEM—Activate Full Aura Release. Duration: 60 seconds."

[✔️ Full System Aura Engaged. Slaughter Mode Activated.]

A purple-black storm burst from his body.

Every step he took cracked the earth beneath him.

He stomped down—sending a shockwave that obliterated twenty enemies.

On a ridge nearby, the seven princes watched the battlefield.

Jin Seo-Jin, Second Son of the Spear Clan, clenched his fists.

Jin Seo-Gi, from the Poison Clan, narrowed his eyes.

> "That energy… isn't ordinary martial art."

Even the First Prince, of the Sword Clan, said nothing. His gaze stayed locked on Seo-Won.

Now he stood alone—in a sea of corpses.

> "You sent dogs to kill me?" Seo-Won roared, turning toward the pavilions where the other princes stood.

"ANYONE WHO STANDS IN MY WAY—WILL DIE!"

Instructors. Disciples. Even clan observers—silent.

For the first time, everyone realized:

The Fourth Prince wasn't fighting to survive.

He was fighting to take the throne.

And that night, under a blood-soaked sky,

Jin Seo-Won entered the war for the legacy of the Heavenly Demon Sect.
