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

Morning mist still clung to the academy grounds, but inside the elite training chamber of the Heavenly Demon Sect, the air burned like fire.

Jin Seo-Won's body was covered in shallow wounds. His breath was heavy, but the fire in his eyes never dimmed.

[Intensive Training Program — Demon Core Refinement: Level 1]

[Side Effects: Internal pain. Meridian fracture risk: 3%. Base power increase efficiency: +217%]

> "Continue," he whispered, blood dripping from his lips.

Dark aura surged from his body in waves, thick and suffocating, threatening to crush anyone nearby. Behind him, the faint image of the Yasha Demon Sword pulsed with a life of its own.

> "I can't stop. Not even for a moment."

> "Because they won't wait for me to grow."

Elsewhere, in the headquarters of the Sword Clan, the seven clan leaders sat in a secret gathering.

They sat in a circle, their faces veiled in the dim blue light of a floating lantern above.

> "Jin Seo-Won…" murmured the Wind Clan Leader.

"The discarded prince… is shaking the foundation of everything."

> "Still too early to call him a threat."

> "But he's now the wielder of a demonic heirloom," the Spear Clan Leader said.

"That's not something we can dismiss."

The Sword Clan Leader stared at the center of the room.

> "The sect will soon hold a tournament to select the heir. If he joins… we must prepare countermeasures."

> "And if he wins?" the Poison Clan Leader asked, his voice sharp.

From the shadows behind them, a new voice cut through the air—the Sect Leader stepped forward, his black robes flowing as if moved by an unseen wind.

"then the fate of the sect will change."

At the same time, Soo-Ran and Do-Yoon stood outside Seo-Won's training room.

Through a crack in the door, they watched his body emit waves of demonic aura, shaking the stone floor beneath him.

> "Is he… still human?" Soo-Ran whispered, wide-eyed.

> "He's not just human," Do-Yoon replied.

"He's a threat to the entire order we know."

Later that day, as Seo-Won opened his eyes from meditation, the system spoke within him:

[New Effects: Resistance to low-level poisons. Minor wound regeneration active.]

[New Title Acquired: "One Who Challenges Fate."]

And for the first time since his regression…
