Zatiel butchered his way up to the last heaven. He took his time and made sure his energy, soul, and body were at their absolute peak before facing the one hundred Peak Rank 5 Demon Lords.
When a Challenger faced the last of the Myriad Demonic Heavens, the Demon Lords would attack in teams of ten individuals.
However, since Zatiel chose to attack the Demon Lords instead of waiting for them, he would have to fight with all of them simultaneously.
The Demon Lords waited in the sky with crazy yet blind expressions until the Neo-Demon appeared in front of them. Those eyes displayed an immense and chaotic slaughter intent as they focused on the person they needed to kill no matter what.
Every one of those Demon Lords' had gargantuan bodies, with the tinies reaching three hundred meters in size and the most enormous one million meters.
They covered the sky and resembled a heavenly demonic tribulation created to annihilate anyone foolish enough to face them.
Zatiel did not hesitate to unleash all of his power. He fused with his Law Avatar, activated his Symbiotic Armor, and entered Doomsday Incarnation's mode.
A dark armor that was the combination between the Tree of Massacre and his Laws covered the Neo-Demon, and bone spikes shrouded in purple superheated plasma emerged from his elbows and knees.
The All-Devouring Domain twisted spacetime around Zatiel, and a crazy amount of energy overcharged every single one of his cells.
With all these powerups, the Neo-Demon's aura reached the Early Hollow Sun Domain Stage, and thanks to the unpredictability of his soul invasion spells, he could even face Middle Hollow Sun Domain Stage powerhouses.
Unfortunately, even that strength was not enough to fight one hundred Peak Rank 5 Demon Lord that would launch suicide attacks against him.
"ROOOOAR!" Crazed roars covered the sky as the Demon Lords flashed toward Zatiel.
The Demon Lords were like one hundred meteorites falling from the sky, ready to blast Zatiel apart.
In less than five seconds, the creatures would reach him and overwhelm him with their combined power, but the only thing visible in Zatiel's face was calmness.
The Rebirth Eye glowed, and the eighty-one bone daggers revolving around Zatiel began to glow as their magic matrices and runes activated.
The daggers assembled above Zatiel, and their energy pools burst with power as their runes linked, forming an Animax Soul Rune Formation.
A monster more than five million meters long appeared above Zatiel. It had a draconic head with six Underworld Flaw Crow's eyes, the upper body of a leviathan with a demonic snake tail, and six massive feathered wings.
Despite the creature's imposing physical appearance, it did nothing to deter the Demon Lords. The reason was simple, it was an incarnation made of energy and lacked the aura of a true monster.
Zatiel was not surprised by the creature's lack of might. He knew the rune formation lacked true power and would need something only he could give it.
Golden electromagnetic energy with a white core emerged from the Eye of Life and Creation and fused with four drops of shining purple blood.
Immediately this force flashed up and fused into the runic formation. Then something amazing happened.
"Thump, thump!" A heartbeat, one so powerful that made the sky tremble, appeared and did not come alone since a wave of soul force accompanied it.
The Demon Lords stopped their march and focused on the creature from whom that heartbeat emerged. Even if they were crazy, they still retained their instincts, and they told them something unique was born in front of them.
After that heartbeat, energy transformed into flesh and blood. The creature that was until a few moments ago a rune formation metamorphosed into a true living being.
And things did not end there since a bone armor with purple runes similar to the one protecting Zatiel's extremities covered the creature's body as his six eyes transformed into a combination between an Underworld Flaw Crow's eyes and Rebirth Eyes.
The Neo-Demon fused Genis Drive into the creature, a force meant to be the origin of all life, and four drops of blood with the power to create each a Rebirth Incarnation.
A smile appeared on Zatiel's face as he stared at the creature that would accompany him for a very long time.
'Since you made your first appearance against the Myriad Demonic Heavens, I should name you honoring this fight.'
"Animax Soul Rune Formation: Myriad Rebirth Doomsday Avatar!"
"ROOOOOOOO AAAAAAAA RRRRRRR!" The Myriad Rebirth Doomsday Avatar roared as he heard the name.
His aura grew more potent by the second and did not stop until reaching the Middle Hollow Sun Domain Stage!
He had barely formed the first signs of a soul and still needed to develop his wisdom, but he could understand what happened around him thanks to his connection with Zatiel.
The core of his existence originated from the Neo-Demon's Mind Force, Genesis Drive, and Rebirth Bloodline's power, so more than a new life form, Myriad Rebirth Doomsday Avatar could be considered an extension of Zatiel's soul.
Under normal circumstances, some of the Demon Lords would have run after feeling the duo's power, but despite their instinct telling them the fight would end in their death, the force affecting their soul was too strong.
After a second, they renewed their march, and this time they would not stop for anything.
Unfortunately for them, that lapse in battle awareness was all Zatiel needed to enter inside Myriad's body and fuse with the creature's heart.
Myriad Rebirth Doomsday Avatar, now with a black hole as a heart, opened his enormous maw and started to devour.
Ancestral Root cut Zatiel's connection with the natural energy, and not even now could he overcome that interference.
Luckily, natural energy was just one of the many forces around him.
In normal circumstances, Zatiel lacked the power to affect them. Nevertheless, by fusing with the creature's heart, he gave Myriad the ability to display a wisp of the true power of the Absolute Unity Omega Law.
Around Myriad's maw, a terrifying vortex that devoured the countless forces that created the universe formed, as the black hole in his heart rotated faster and faster.
This power was similar to Ezequiel's ability in which he made the power of the universe part of him.
However, unlike the Supreme Neo-Demon, who achieved that by communing with the forces around him, the Neo-Demons' Ancestor method was cruel and tyrannical.
Despite the feeling of death growing stronger and stronger, the Demon Lords kept moving forward.
Just as they were about to clash with the creature, darkness enveloped the sky. The vortex had devoured every form of light in a radius of thousands of kilometers.
The darkness did not remain for long since the Demon Lords saw a white light the next second.
"¡BOOOOMMMM!"
A beam of super-compressed force carrying a myriad of powers blasted forward, disintegrating all the Demon Lords in his path and splitting the storm clouds apart.
One of the key components of this beam and responsible for its extraordinary annihilating power was Antimatter.
A third of the Demon Lords, including the ten whose power reached the absolute peak of the Marquess' level, were disintegrated to an atomic level in an instant.
