Ancestral Root's eyes showed the awe he felt when he detected the power in that beam.
When Zatiel's fused into Myriad's heart, he pushed the creature's aura to the Late Hollow Sun Domain Stage, and the beam they released after savagely devouring the World Strength reached the Peak of that level.
The difference in power between the Early and Peak Hollow Sun Domain Stage is greater than the difference between the 1st and the 6th Engraving Stage.
Zatiel's battle power growing so much after unleashing Myriad was something that amazed the Artifact Spirit.
However, Ancestral Root also perceived the backlash the duo endured after unleashing that beam.
Myriad and Zatiel split the next seconds, and their faces were pale.
The beam had drained the energy stored in the All-Devouring Domain along with the Neo-Demon's energy pool. Wounds covered Zatiel's inner organs and had many torn muscles.
Myriad Rebirth Doomsday Avatar also had injuries. The bone daggers that supported his body had small cracks, and their energy pools were almost empty.
While those injuries were not minor, they would not affect their battle power for the time being. Thanks to the Rebirth Bloodline's power running through them, the duo could heal without the need for external help.
Zatiel focused on the Demon Lords, and the smile on his face grew wider after seeing their condition.
The beam only killed a third of them, but it also unleashed gales of destructive power that severely harmed all the others. Some Demon Lords were having a hard time stopping their bodies from melting due to the nocive energies that invaded their cells.
Of course, even if they were about to die, as the killing machines they were, the Demon Lords ignored the pain and roared as they flashed toward Zatiel and Myriad.
Zatiel no longer had any Elemental Chaos left, but Rebirth Force fueled the bone sword as Mind Force gathered inside the Rebirth Eye, ready to unleash Soul Eradicators.
Myriad's body changed, becoming slender and shrinking to less than fifteen meters. The creature's eyes glowed, and the world around him changed to one overflowed with red scars.
The Underworld Flaw Crow could perceive the Flawed Universe, and so could Myriad Rebirth Doomsday Avatar. The Rebirth Eyes even enhanced that ability, allowing them to reach the level of Primordials.
Since Myriad was an extension of Zatiel's soul, the Neo-Demon shared the creature's field of vision, and his Rebirth Eye showed him the red scars that covered the sky, the ground, and the Demon Lords.
"Let 's go!"
"ROAR!"
The duo flashed toward the Demon Lords. Purple superheated plasma covered the head of one and the sword of the other.
Myriad was the first one to reach the Demon Lords. His speed was so high that average Hollow Sun Domain Stage powerhouses would find it hard to respond to his attacks.
The creature was much faster than Zatiel, and the Neo-Demon needed to use Shooting Star End to surpass him. This amazing natural speed was thanks to the power of the Underworld Flaw Crow and Pit Fiend's Order Snake Heart.
Before the first Demon Lord could even react, a flaming hole appeared in his head. Myriad's Rebirth Flames incinerated his brain and True Soul.
Zatiel displayed his exceptional martial skills by cutting Demon Lord's head and using the rest of the body as a shield against the attack aiming at his back.
The Neo-Demon and the living Animax Soul Rune Formation started a carnage in the sky.
One flew so fast that the Demon Lords could not keep up with his movements, and the other used his incredible battle awareness and martial skills to defend from every attack before unleashing a killing blow.
Finally, the last Demon Lord perished after a sword strike divided his three hundred thousand meters tall body in two.
Zatiel was exhausted. He no longer had any form of energy in his body and would have fallen unconscious if it wasn't for the All-Devouring Domain using the corpses of the Demon Lords to help him recover mid-battle.
The next moment, Myriad's body glowed before disintegrating into particles that gathered into the eighty-one bone daggers.
His eighty-one energy pools were empty, and the Rebirth Incarnation's droops of blood that allowed him to pass from an energy construct to a creature made of flesh and blood had run out of power.
Zatiel stared at the daggers and nodded after detecting the soul waves inside them. While Myriad's body required Rebirth Incarnation's blood and Genesis Drive to unleash his full power, his soul remained even after all his energy was gone and would grow stronger with time and nurturing.
'The eighty-one bone daggers became his soul's vessel. As long as one of them remains, I can reform Myriad's soul and body no matter how much damage he endured.'
The Rebirth Eye collected the bone daggers into the Dream Dimension before a power teleported Zatiel out of the sky.
More than eight years of flying up left him thousands of millions of kilometers away from the ground. If Ancestral Root had not teleported him, the Neo-Demon would have needed months to descend.
"Congratulations Challenger. You have completed the Myriad Demonic Heavens with a perfect score. Next comes the final test, the Test of Strength. Take all the time you need to rest, and let me know when you are ready to start."
Zatiel nodded to Ancestral Root and unleashed the full power of the All-Devouring Domain to speed up his recovery. Since the test was over, he could once again swallow natural energy.
One stream went to his energy pool, another to his Dream Dimension, and the last to his body. The Neo-Demon also ate a bunch of origin stones to recover Soul Origin.
.....
In a High World whose surface was covered entirely by water, a battle between six individuals that cracked the sky was going on.
On one side, there were three members of the Leviathan Race. Two of them had enormous bodies, but the strongest adopted a humanoid form with black metallic skin, blue eyes, and large muscles.
There was a Law Domain around the last Leviathan formed by the Laws of Devouring and Physical Potential.
Facing those in monstrous form were two old men from the Atlantean Race. They resemble humans, but scales were covering their chest and extremities.
The one fighting the strongest was a young man with white hair and white lightning covering every piece of his body. He had a halo on his back and forehead and seemed capable of wielding the power of the world.
One of the old Atlanteans wielded a trident and displayed impressive physical might and martial skills as he clashed with the Leviathan. The other's battle style focused on long-range, and he constantly fired spells against his enemy, creating water incarnations with the form of countless beasts.
Ezequiel was in Asura Form, with his twelve arms combined into only two. His battle power reached the Late Hollow Sun Domain Stage after fusing with Entropy, but despite his enemy soul force putting him at the Early Hollow Sun Domain Stage, the Supreme Neo-Demon could only equal him.
It was clear that the humanoid Leviathan was a genius as well. He had a technique that allowed him to draw copious amounts of natural energy forcefully, which worked perfectly with his race's natural devouring talent.
The Leviathan would then transform that energy into kinetic force, enhancing his physical might tremendously.
Whenever the Supreme Neo-Demon and the Leviathan genius attacks collided, giant space cracks would form in the sky.
Ezequiel's eyes narrowed as he felt that Entropy could not keep fighting for much longer. His Sanctus Battle Partner may be powerful, but he was still an infant and grew tired quickly.
A decisive light appeared in the Supreme Neo-Demon's eyes as he pushed his body forward, ignoring his defense.
Ezequiel's fist, in which a massive amount of energy had gathered, landed in Levithan's chest, right above the heart.
The Leviathan genius flew away while puking blood. Instead of returning to the battle, he took advantage of the impulse and escaped.
When they saw their leader running away, the other two Leviathans pushed back the old Atlanteans and left the battlefield.
Ezequiel saw the Leviathans running but did not chase after them. He had severely injured his enemy in the last clash but also received a deep wound.
There was a fist print on the right side of the Supreme Neo-Demon's chest. The Leviathan genius managed to land a punch that shattered his ribs and severely harmed his lung.
Ezequiel took a moment to analyze the fight, figure out what he did right and what could be improved. As he went through that mental exercise, he narrowed his eyes and took a metallic tadpole from his space ring.
'A message from the Magi World.'
