Abyssal Lord of the Magi World

In a remote location of the Prima Universe, there was an area full of asteroids and dead stars. Even a Law Overlord would not see anything wrong with this place at first sight, but all of a sudden, space began to tremble before a red cocoon the size of a world appeared.

Cracks began to arise on the cocoon before part of it shattered, and a tsunami of Astral Chaos emerged from the opening. The red force obliterated everything in its path, under a weight that could collapse black holes. 

A figure emerged from the ocean of primeval Astral Chaos that could eradicate Low Worlds. What escaped that apocalyptic force was a Rank 8 God.

Although, to be more precise, the only thing left of the Beyond Shackles existence was a small part of his chest.

Once that piece of the Rank 8 life form left the Astral Chaos, it exploded, showing a gray humanoid with tentacles instead of legs and a yellow robe covering his body.

The King in Yellow looked at the primeval Astral Chaos with eyes full of murderous rage. He managed to escape by entering the Rank 8 God that he left by his side and using that body as an escape capsule.

At first, he thought that everything went according to his plan. Even when Zatiel showed the Red Primeval Sun, he calmed down almost immediately, but even in his wildest dreams, he never imagined that a Rank 6 life form could fire a World-Ending Spell.

'Those violet seals, they were the key for that attack, but how? Even Primarchs could not create something like that.' The King in Yellow's thoughts were interrupted due to his instincts screaming like crazy, and he turned around just in time to see a bone sword penetrate his chest.

Zatiel's cold eyes stared at the King in Yellow as he pushed his bone sword deeper. Armor covered his body, and six swords were floating around him.

The Neo-Demon was in his maximum state, with Bloodline Apocalyptic Metamorphosis activated and having fused with Myriad. 

A purple electric matrix covered his bone sword and both of his arms, making them release an absurd level of energy.

The King in Yellow clenched his teeth as the bone sword pierced so deep into his chest that it managed to come out of his back. 

He was shocked by Zatiel's state. There was no wound on the Neo-Demon, so that meant that he managed to control the spell with such precision that no collateral damage reached him.

At this moment, when they were next to each other, the King in Yellow was able to feel an aura in the violet seals that were vanishing from Zatiel's skin, and the rage in his heart increased as he thought of someone.

'That fucking tree!'

The King in Yellow figured out that the one responsible for those violet seals that allowed Zatiel to mobilize a Rank 9 spell was no other than the World Tree.

Despite his wrathful state, the King in Yellow did not lose focus, and he felt how the bone sword was about to unleash an extremely destructive force. 

Instead of dodging or blocking the bone sword's power, the King in Yellow chose a different path.

Zatiel was about to unleash the power he charged in the bone sword when he felt the King in Yellow's hand touch his chest.

"Karma Inferno!" The moment the King in Yellow pronounced those words, the billions of red threads coming out from Zatiel shone. 

An immense sense of danger assaulted the Neo-Demon, but no fear appeared in his eyes, and he only focused on unleashing all the power of his next spell. 

"Apocalyptic Supernova Immolation!"

The purple matrix covering the bone sword glowed before extending into the King in Yellow's insides at a monstrous speed.

They both started together. The karma threads ignited, making a red fire cover Zatiel's entire body, while the purple matrix torched the King in Yellow's insides. 

As the flames of karma and rebirth inundated their bodies and harmed their souls, the King in Yellow and Zatiel felt unbearable pain, even for individuals with their level of willpower.

However, the only thing in their eyes was killing intent, and instead of trying to separate, they channeled more energy into the flames.

"¡AHHH!"

"¡AHHH!"

They screamed as the power of karma and rebirth reached a level capable of instantly incinerating anything beneath Rank 7.

The King in Yellow sensed the purple matrix extending deeper into his insides, now covering every corner of his body except for his brain. 

He felt how the purple matrix attached to his life essence and used it as food to deploy the purple fire that destroyed his insides. 

On the other hand, Zatiel felt the karma threads piercing deeper into his body, allowing the red fire to infiltrate his bloodstream, but that was only part of its power.

The Neo-Demon felt that the memories of all the people he cared about were being distorted, changing those joyous moments with horrible and treacherous experiences. 

His willpower was powerful enough to allow him to fight back, but he could not stop the negative emotions from invading his soul.

Zatiel's eyes showed the rage and madness plaguing his mind, but he kept control and began to raise his bone sword, enlarging the cut inside the King in Yellow. 

Black blood leaked from every orifice in the King in Yellow's face, but he resisted the pain and put both of his hands over Zatiel's helmet before making the power of karma explode.

The Neo-Demon felt the force affecting his memories and emotions growing stronger, to the point he began to lose track of what was real and what was fake.

He could not allow the force affecting his memories and emotions to keep growing, so he sent a command, and the next second, a purple sun emerged from his right arm, making the electric matrix disappear.

Immediately, the sun fused into the left arm, enhancing the purple electric matrix in this one, and Zatiel took out the hand from the bone sword's handle before punching the King in Yellow's face. 

The King in Yellow was sure that he could resist that fist, as his body was equal to that of a Rank 7 Demon Lord, but when it touched his face, his eyes widened by the immense power he felt.

That punch was not only strong but also fast, heavy, hard, and carried a heat that could ignite a continent in an instant. It sent the King in Yellow flying away, destroying dozens of stars and asteroids on his path. 

Those purple suns were Zatiel's Apocalyptic Extremity Suns, the unique ability of his Bloodline Apocalyptic Metamorphosis. 

The purple suns had two powers, the first being an overall enhancement. If Zatiel used the power of the three on his entire body, he would grow thirty percent more powerful, but if they concentrated in a single extremity, it would improve one fold.

By fusing two on his left arm, the Neo-Demon improved everything about the extremity by two hundred percent!

The second power consisted in fusing with the enemy's body and devouring their life essence to unleash an endless rebirth fire. The Neo-Demon called this ability Apocalyptic Supernova Immolation.

Zatiel's face twisted by the pain and hate that was invading him, making it hard for him even to think, but after using his Mind Force to appease his soul, he flashed toward his enemy.

The King in Yellow regained control over his body only to see an enraged Neo-Demon flashing toward him, and the first thing he did was a hand seal.

A dark eldritch aura emerged from the King in Yellow, as the illusion of a horrible creature that resembled a larva with tentacles holding a flute appeared above him.

The next instant, a flute materialized in the King in Yellow's hands, and this one began to play it.

No sound came from the flute, but Zatiel stopped mid-flight, and he grabbed his head as the craziness in his eyes grew stronger.

"AHHHHHH!" The Neo-Demon screamed in agony as the negative emotions filling him drilled deeper and deeper into his soul.

The King in Yellow smiled as he saw the madness in the Neo-Demon's eyes, and he kept playing the flute, but all of a sudden, his enemy vanished from his line of sight.

He detected the presence of the Neo-Demon behind him but was too slow to respond, and a large cut appeared in his back and inundated him with even more rebirth fire before pushing him away.

'How did he break my seal in space and teleported so silently that I was not able to detect him until it was too late!' 

The answer to his question emerged the next second when he saw a lonely bone sword a few hundred meters ahead of him.

Without any warning, the Neo-Demon materialized next to the bone sword and attacked him, making another large cut on his chest and sending him flying away again. 

'Beyond superluminal speed, using the bone swords as beacons.' The King in Yellow immediately figured out the trick behind Zatiel's monstrous speed, and his eyes narrowed when he detected another lonely bone sword on his path.

He made a hand gesture, different from the previous one, and the illusion of an elephant-like humanoid monstrosity appeared above him. His muscles grew larger, and an immense sense of physical power emerged from him. 

Just like the King in Yellow expected, Zatiel appeared next to the bone sword, and then one fist and one blade collided.
