Heinz stood in the center of the dark red flaming soul force that obliterated the entire mountain range, but he was not the origin of it. The destructive power came from the Cultivator's sword, which began to release a monstrously sinister and chaotic aura.
The dark red sword's aura kept growing more and more potent and did not restrain itself, slowly expanding through Heinz's body.
Right now, the sinister aura limited itself to the Cultivator's forearm, making a violent expression full of murderous rage appear on the face of this one.
Roku, Dean, and the rest of the Gods Slayers could feel the evil soul inside the dark red sword. Although they grasped the concept of Sword Spirits, this seemed something different, as the sword gave them the feeling of being a proper life form, not a mere amalgamation of spiritual energy.
"¡BOOM!"
Another explosion echoed through the continent, but this one did not come from the dark red sword but from within Heinz's chest.
Dark aura wrapped the Cultivator as his Infinity Heart began to beat harder and harder. Heinz's body grew three times taller, reaching fifteen meters, as bone armor covered every piece of it, and that was not all, as a new weapon emerged from his left hand.
The bone weapon that emerged had the form of a broadsword, with dimensions that fit the Cultivator's new fiendish body.
Heinz turned toward the dark red sword, which began to change, transforming into another broadsword. Once he did that, he focused on the opponent in the sky, and his violent and fierce aura exploded.
"ROAR!" The Nº1 Sky Breaker roared, and as he did that, the Neo-Demons focusing on him all began to cheer due to their leader's great power.
On the other hand, Sophia and the rest of the Sky Breakers adopted solemn expressions when they felt the dark red sword's evil aura. They stared at each other and silently nodded as they pushed their focus to the limit.
Gwyn, who was the violent aura's target, frowned. This contest was just a practice battle, but he could feel the desire for slaughter coming from the Cultivator.
Unfortunately, the Holy Son did not have time to worry about it since golden channels appeared in Heinz's bone armor, and then, this one vanished.
With speed almost two times faster than before, Heinz covered the distance between him and the Holy Son in less than a millisecond before unleashing a ferocious attack.
Gywn was barely able to block the bone sword with his halberd. To his shock, the transformation not only increased Heinz's speed, as the Cultivator's strength also reached a monstrous level.
The bone sword's momentum was so strong that it sent the Holy Son flying away, and before this one could regain control of his body, Heinz appeared above him and attacked with the dark red sword.
Pain and awe appeared in Gwyn's eyes as he felt the dark red sword easily cutting his armor, which should be powerful enough to endure Primary Sun Domain Stage full power attacks!
And things did not end there, as the dark red flaming soul force invaded his body and attempted to not only destroy his flesh and blood but also burn his soul.
Gwyn saw Heinz immediately chasing after him to continue the onslaught, and rage appeared in his face. The Eldritch Ghost Underworld shone with even more power, making the Holy Son's body grow larger and stronger along with his armor.
When the halberd and the bone sword clashed, Gwyn once again regained superiority in terms of strength.
Seeing his opponent grow stronger only made Heinz's violent aura more potent. A sinister smile appeared on his face as he attacked with the dark red sword.
Gwyn barely managed to counter the next attack. He felt how the dark red sword's striking power was even more potent than the bone sword, but he still had the upper hand.
Unfortunately, before the Holy Son could overcome the Cultivator, an explosion of dark red flaming soul force blasted him away.
Unlike previous times, Heinz did not immediately pursue Gwyn. As the dark red sword's evil aura expanded, an annoyed expression appeared on his face.
Gwyn did not lose the chance, immediately regaining control over his body before making his bloodline force burst.
The illusion of a hellish pyramid appeared behind the Holy Son, and from it, thousands of souls emerged. They were all people Gwyn killed.
Not even in death, these people could rest because the Holy Son used the Eldritch Ghost Underworld to confine their True Souls.
Although using these True Souls to attack the opponent would be effective, Gwyn's Law Bloodline allowed him to do much more. His bloodline eyes glowed, and the tormented souls showed expressions of agony as they morphed into seals that began to rotate around the halberd.
Gwyn's halberd transformed into a silvery flaming soul tornado.
Heinz's expression returned to one of murderous rage once the evil aura stopped expanding, reaching right beneath his shoulder.
When he saw the state of his opponent's weapon, he focused on his sword, making the dark red flaming soul force grow like a tsunami.
The Sky Breaker and Holy Son stared at each other for a second before flashing forward with all their strength!
A cataclysmic battle occurred in the sky as two natural disasters clashed one against the other, unleashing waves of destructive energies that could boil oceans and transform continents into withered lands.
The Supernova Domain Magi, seeing the battle, could not hide their shock. Both the Cultivator and Eye Holder were at the 5th Engraving Stage, but their battle power touched their level.
While they were still a step away from the Early Supernova Domain's battle power, their power would allow them to face them and put up a good battle.
Gwyn and Heinz showed a talent that could allow them to face the leaders of the Magi World's great organizations when they reach Peak Rank 5, a feat only Gabriel Rebellion had been able to display in the past one hundred thousand years.
As they continued their fight, the consequences of pushing themselves beyond their limits began to show. Gwyn's bloodline eyes were bleeding, and Heinz's body displayed evident signs of internal damage.
"¡AHHHHH!"
"¡AHHHHH!"
The Holy Son and the Sky Breaker roared simultaneously as their powers reached the absolute peak, each transforming into cataclysmic disasters.
Gwyn's halberd transformed into the tip of the grey flaming soul tornado as he flashed forward.
Heinz put one sword over the other as the tsunami of dark red flaming soul force blasted around him, and then he pierced toward his opponent.
"¡BOOOOMMMM!"
The clash between the two cataclysmic supernatural disasters unleashed an explosion that could split a continent in two.
Awe appeared in the face of the Magi army as they saw the sky of the Loth Continent burn with grey and dark red flames.
It was as if the firmament got itself on fire!
From the explosion's core, two figures emerged. Gwyn and Heinz were injured and had a hard time standing in the air.
That should mark the end of the battle, but unlike the Holy Son, the Sky Breaker's face kept showing a murderous rage.
The Gods Slayers showed severe expression as they saw how the dark red sword's evil aura began to extend once again and how the soul inside the weapon grew even more potent.
Roku's eyes displayed a light of enlightenment as a word came to his mind.
"Archdemon."
