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

After the haze of the outer mission faded and the disciples returned to the academy, the Heavenly Demon Sect settled into silence once more. But within that silence, something began to grow—resolve, strategy, and a burning hunger for power.

Inside a secluded pavilion assigned to Team 7, Jin Seo-Won sat cross-legged atop the cold stone floor. His body was covered in wounds from battle, yet his black eyes burned with purpose.

> [Body scan complete. Initiating regeneration sequence.]

[Internal injuries: 72%. Prioritizing healing.]

A soft aura enveloped his body, knitting torn flesh and mending damaged meridians—injuries no ordinary medicine could treat. From a distance, Do-Yoon and Soo-Ran watched in silence, unable to comprehend the power at work.

"He's… really not the same anymore," Soo-Ran whispered.

"Starting tomorrow, we'll enter the next phase of training. I'll teach you the second-level techniques."

Do-Yoon bowed deeply, his breath trembling with excitement. "I'll follow you until death!"

A faint smile touched Seo-Won's lips. But within, the storm he was preparing was far more terrifying.

Later that night, once his teammates had fallen asleep from exhaustion, Seo-Won sat alone in the meditation chamber. He opened his system interface.

> [SYSTEM: Heavenly Regression Protocol v1.2]

[Main Mission: Prepare for the massacre in three years.]

[Current Phase: Early Preparation]

> [New Option Available: Martial Knowledge Expansion – First Step]

[Description: Access hidden martial arts techniques from the future and integrate them into your current body.]

His body shuddered. Complex diagrams of martial formations and energy paths surged into his mind. Every movement, every meridian flow—this was a martial art that did not belong to this era.

> "If I want to save Mother… I have to become a monster even this sect can't control."

The next morning, while the rest of the academy still slept, an explosion of aura shattered the training wall behind the pavilion.

Seo-Won stood at the center of the ruined sparring ground. Do-Yoon lay collapsed on the ground, his body trembling—but his eyes were blazing with determination.

Seo-Won nodded. "Get ready. This technique isn't meant for those who wish to live comfortably."

Soo-Ran stood at the edge of the field, clutching the scroll containing last night's teachings. In her heart, she began to understand…

This man didn't just want to survive.

And she would be there to witness it all.
