In that very moment, the Heavenly Demon showed the King of all Evil the strength of “mere mortals,” beings born with no special bloodlines, no special powers, and nothing but themselves and the world around them.

He clenched his fists, unleashing the power he had waited this entire time to release, ensuring he would deal as much damage as possible.

All those blows, all those attacks that could still not deal enough damage—it was all for this moment.

The accumulation of it all, a full release of every cursed stigma imprinted into each wound, a curse so strong and yet… so pure, that not even the King of all Evil could detect or cancel. 

“{Cursed Fist Explosion: Release}!” 

“Ngh?!” 

Before the Demon could speak another word, he felt his entire body inflating. Each punch and blow he received across his body activated a “curse” the Heavenly Demon had imprinted into the wound. These curses rapidly began overflowing with light, becoming runes of their own across his body. 

“W-Wait a second, this is…?! AGH!” 

As he released this power, the curse exploded into flames, injected directly into the Demon’s damned body—a powerful technique that not even the King of all Evil could stop. 

“Are you fucking kidding me?!” 

BOOM! BOOM! BOOM! BOOM! BOOM! BOOM! 

“UUUAAAGGH…!” 

As he screamed in agony, his body bulged and bubbled. Each explosion within his body caused some of his flesh, muscles, and bones to explode as well, flying everywhere in a bloody mess. 

“Were you underestimating me, you fucking bastard?! Taste the power of the strongest of Bestia!!!” 

With a furious roar, the Heavenly Demon reached the King of all Evil while his body continued to explode, swinging his fists and even using his wings as a secondary pair of limbs to fight, as if they were arms as well. 

“I’m going all-out! I cannot let this bastard catch a break! I’ll overcome this! For Anna, for my love, for my son!” 

With his mind completely set on destroying the monster in front of him, the Heavenly Demon combined his techniques, his martial arts converging as the power of the Spectral Guardian, emerging from his Soul and Aura, moved with him. 

“{Abyssal Cursed Demonic Seal Release}: {Dantian-Destroying Spear Finger}!” 

Using the claws of his wings and the fingers he had left, he pierced the King of all Evil’s body repeatedly, leaving tiny holes through his muscles, skin, and bones. 

CLASH! CLASH! CLASH! CLASH! CLASH! 

“GRAAAAGGH?!” 

As the Demon groaned in agony and vomited blood, his internal body still exploding, the Heavenly Demon noticed the monster’s aura transforming into a massive crimson fist made of demonic flames, swinging down toward him. 

CLAAASH! 

“Y-YOU LITTLE BIRD…! HAHAHA! THAT FREAKING HURT!” 

The King of all Evil laughed as he grinned back at the Heavenly Demon. His body was covered in deep wounds, one of his arms was now missing, and he was bleeding profusely.

And yet, he still had the strength and control to attack the Heavenly Demon! 

“Then this’ll hurt even more!” 

The Heavenly Demon roared, thrusting his arms forward as his Aura wrapped around them. All the power of his cursed seals and the white void he could unleash through his form, gained through regret, converged. 

“{Abyssal Cursed Demonic Seal Release}: {Soul-Shattering Cursed Black Tiger’s Fangs}!” 

His aura transformed into a giant black tiger out of nowhere, roaring ferociously and tearing through the Demon’s Aura, destroying the arm used to block him, and then biting and ripping through the scales and skin of the Demon’s arms, which he used to defend himself. 

“BASTARD!” 

The King of all Evil grew more desperate, roaring back and kicking the Heavenly Demon in the head, crushing his left eye as it exploded into a bloody mess, nearly reaching his brain with the sharp claws of his fingers. 

BOOOM! 

The Heavenly Demon felt an immense sharp pain in his skull. His entire body had never endured so much pain before, yet this pain gathered into even more strength. He opened his beak and bit the Demon’s leg, tearing it apart from his body. 

The King of all Evil cried in agony. The Heavenly Demon grabbed his leg and burned it to ashes with his black flames, turning the power gained by incinerating a piece of the Demon’s body into a surplus explosion of energy. 

While his empty eye socket kept bleeding, the Heavenly Demon pushed forward, kicking the Demon’s face and then rushing toward his stomach, unifying the fingers of his hand into blades with his Aura and stabbing him dozens of times, aiming at his intestines and even his ribs. 

“{Abyssal Cursed Demonic Seal Release}: {Dismembering Abyssal Rhinoceros’ Horns}!” 

His aura transformed into a massive, monstrous rhinoceros made of black miasmic energy and demonic kin flames, relentlessly stabbing the Demon’s stomach and opening it up, revealing his intestines and stomach. His ribs were being destroyed as well. 

CLASH! CLASH! CLASH! CLASH! 

“RAAAAAH!” 

The Demon roared even as he was being torn apart like this, rushing toward the Heavenly Demon and punching his stomach and chest, nearly breaking his thorax and managing to shatter three of his ribs. 

CRASH! CRASH! CRASH! 

The Heavenly Demon vomited blood as one of his broken ribs pierced his lungs, but he didn’t care. He quickly twisted his body, his blood and aura merging as it burned out, granting him even more strength. 

“I cannot let him win! If I do, this monster is capable of destroying everything…! I cannot lose—not after everything, not after we’ve come so far!” 

His aura transformed, rapidly changing shapes, embodying his pain even further. The Demon suddenly saw something strange. 

“W-Wha…?!” 

His eyes widened in awe, amusement, and shock as the Heavenly Demon’s Aura began to transform into a landscape.

A world! 

The world showed visions of his own life, of his pain, of his suffering—from when he was nothing but a little crow trying to survive alone after his family was killed, how many times he was tricked, taken advantage of, and nearly killed.

During that time, he was captured by a gang of slavers, tortured, enslaved, and sold as an exotic “creature” as the only red-eyed crow in the world.

Or when he broke free from his slaver, freeing dozens of other slaves with him, and all of them tore that slaver to pieces like rabid beasts.

How he began walking the Demonic Path not because he chose to, but because it was the only path he could walk in such a harsh world.

The times when authorities sought him, and he had to hide and prepare for battle, trapping and killing his pursuers one by one, earning himself the reputation and title of a “Demon” by many.

How his dark powers developed, and how he burned a malefic rune of his own creation into his flesh, embodying his pain and granting him powers he never thought possible.

How he struggled, nearly at death’s door, cornered by many orthodox cultivators and almost killed by an immortal called to solve the problem.

And even that time when he ascended as an Immortal, only to be thrown into an even more dangerous world of Immortals, never finding the true peace he wanted for himself.

How he was forced to fight endlessly, to shed blood for a living. Even as he ascended, the battles became never-ending; there was no possible future for him other than fighting to the death.

And as he went through countless challenges, how each one shaped him into the world’s Heavenly Demon, the vilest of them all, and the leader of the revolutionary group of “Demonic Cultivators” who fought against the rules and regulations set by the orthodox cults and the corrupt Heavenly Court.

And how, after struggling all his life, he became a Venerable, ascending to the ultimate pinnacle of the world, venerated by all Demonic Cultivators as their God and feared by everyone else as a Demon of Evil.

And yet, at the end of that journey, he clashed against the pinnacle of his opposite side, the one he thought he was born to kill, to defeat.

But… he was unable to.

Instead of dying, Heaven itself stopped them from killing each other. In that moment, he realized that fighting was no longer the answer to his problems.

Although reluctant at first, after he got to know that woman, he learned she wasn’t as he believed, and that her life was very much like his own, riddled with pain and agony in every phase.

From childhood, she suffered and kept suffering all the way to the position she reached.

And yet…

Why?

Why did she choose a different path? What allowed her to even choose?

He believed that anyone born and shaped the way he was would always end up in the same position—a resentful person who wanted the world to burn and to rebuild a new, chaotic world from its ashes.

And yet, despite facing the same challenges and enduring so much suffering, she chose the opposite. She fought against evil and helped the poor, even when she barely had anything herself.

Despite how much he hated her…

He couldn’t help but feel admiration for her, a level of admiration he had never felt for anyone before.

This woman… She was the one who shaped his life from that moment onward, until now.

His Aura transformed as the Heavenly Demon’s thoughts, memories, and the many challenges he had gone through became his strength.

They converged—all of these images, all of it—within his fists as he attacked the Demon in front of him, an ultimate evil, a true monster with no redeeming qualities.

An agent of destruction and chaos, someone who valued no life.

And then, the two precious treasures in his life shone brightly amidst the darkness of his powers.

Song, his beloved son, the innocent soul born from the union between him and the Heavenly Empress, who had a tragic end.

And Anna, his adoptive daughter who came from beyond the stars and saved his son while teaching him about empathy. 

“THIS IS ALL I HAVE!”
