Abyssal Lord of the Magi World

The inhabitants of the Yuru continent saw how a sea of flames and darkness covered the sky. Even the dumbest devil could understand by now that the phenomena affecting their home occurred due to a fight between entities whose powers were beyond their comprehension. 

Zatiel and Eon Six managed to regain control of their bodies less than a second after the explosion sent them flying away. The Tree of Massacre's armor protected the Neo-Demon from collateral damage, and the Supernova Race man channeled energy into his armor. 

The rest of the Devil Marquises ended up with extensive burn injuries, and some of them even vomited black blood since they could not stop the Dukes' energies from poisoning their bodies. As for the Devil Counts, they were at the edge of the battlefield, so none of them died, but many withstood severe wounds. 

The Devil Lords moved even farther from the battlefield after that, with only Zatiel and Eon Six remaining in their original positions. 

Darkness and flames covered the figure of both Duke Krior and the Rank 6 Pit Fiend, but they dispersed the next second as two bursts of energy manifest themselves. 

Everybody could see the condition of the Devil Dukes, and despite their monstrous physical might, that last clash injured both of them. Duke Krior lost his right arm, and cracks filled his Solid Light's armor.

The Darkness Poison Duke returned to his natural form after the clash. His right horn was missing, and there was an indentation in his head, proof of a fractured skull. 

As their energies spiked, Duke Krior's arm regenerated, and the Darkness Poison Duke's skull began to heal. The duo displayed extraordinary healing abilities, but the truth was that the new limb and tissues would be weaker than the previous ones since they lacked the tempering of the laws. 

In less than a second, the duo's bodies fully healed, and they did not hesitate before attacking with their full power once again.

The apparition of their wounds marked the start of the real fight between the Dukes. Everything before was just a test. 

They both moved with incredible speed. Their momentum and drive constantly broke space to the point that huge scars that could split a Rank 4 life form in two filled the Yuru continent's sky.

Some of the deadliest scars reached Zatiel and Eon Six, but the duo only needed to unleash the might of their energy pool to seal the space around them. 

The Neo-Demon's Rebirth Eye and the Supernova Race man's Eye of Time targeted one of the Devil Dukes and quietly charged their most potent spell. 

Neither Duke Krior nor the Darkness Poison Duke noticed the duo's intention. The Devil Dukes could not give themselves the luxury of splitting their concentration in a fight of this level, not to mention they were confident that their power and contracts protected them from their underlings. 

The Darkness Poison Duke kept switching between his Order Snake, Order Dragon, and natural form during the fight. He displayed no fixed patron, making it impossible for anyone to predict his next move, but the Order Aura diminished quickly. 

Duke Krior, on the other hand, combined the explosive might of the Law of Fire with the speed of the Law of Light. He improved his constitution with Solid Light and, at the same time, made weapons capable of unleashing crazy amounts of energy. 

More and more wounds appeared in the duo's bodies and souls as the fight carried on. It reached the point they could no longer regenerate their bodies due to the lack of energy, making their battle power gradually decline. 

Their Hollow Sun Domains kept burning as strong as at the beginning of the battle. However, Zatiel knew it was just a matter of time until their Soul Origin depleted and the Dukes lost their ability to project their Inner Law Dimension into the real world. 

Usually, Devil Dukes would never allow a fight to reach this level since they would end severely injured even if they won. Having wealth and being wounded in Baator or Abyss was the same that suicide. 

Zatiel's knowledge of devils' nature was as high as it could get. He was sure that both Dukes made pacts with other Rank 6 Devil Lords. The Sun Law Domain existence on the winner's side would appear and protect the Devil Duke until his wounds completely heal. 

The loser's destiny was to perish and have their soul and Demonic Bloodline devoured. The Rank 6 Devil Lord, with whom he made a pact, will not appear to rescue him. 

In his Order Dragon form, the Pit Fiend once again attempted to ram Duke Krior, but this time, the dwarf managed to dodge and shoot a cannon of light speed fire at the dragon's shoulder. 

"AHHHH!"

The Darkness Poison Duke roared in pain, and the cannon sent his five million meters long body flying away. 

Duke Krior managed to connect a powerful attack, but the cannon's recoil pushed him back and fractured his arms. Solid Light was powerful but consumed copious amounts of energy and Soul Origin, so the Devil Duke chose to reinforce only his vital organs now that his reserves were low. 

The Pit Fiend returned to his natural form after regaining control over his body, and there was a vast gaping hole in his left shoulder. A somber expression appeared on the Devil Duke's face as he felt the amount of Order Aura in him.

Without access to his Order Art, the Darkness Poison Duke's battle power will diminish considerably. Some urgency appeared in his eyes as he pushed even harder against his opponent.

Duke Krior noticed the condition of his opponent and smirked as he fought back. The truth was that his condition wasn't anything better since he was about to run out of Soul Origin, but according to the Devil Duke's calculation, he should last more than his opponent. 

Another clash between the Order Dragon and Duke Krior's flaming fist occurred. None of them overcame the other, and both suffered deep wounds, but a smile appeared in the dwarf when he saw the Pit Fiend's Order Aura finally ran out. 

Fear appeared in the Darkness Poison Duke's eyes, and he turned around before escaping, but Duke Krior immediately chased after him.

Duke Krior was just in range, ready to release another cannon of light speed fire when he saw how the Pit Fiend halted his escape and looked back at him with a smile. 

Before the dwarf Devil Duke could understand what happened, the Pit Fiend's right eye exploded, unleashing a wave of invisible energy that covered not only the Yuru continent but the entire Iron City of Dis! 

Other than his fantastic range, there was nothing special about the wave. It lacked amazing lights or strange phenomena. 

However, the effect it had on the Iron City of Dis was extraordinary.

Million of kilometers away from the Devil Dukes, two lesser devils were fighting, and one managed to connect a fireball in his enemy's face just when the wave appeared. To the shock of both, the fire failed to burn the target.

Inside a castle, a Rank 4 Devil trained the Law of Fire when all of a sudden, he felt a static vail cover the law and made it impossible for him to grasp anything of it. 

A Hellblade Devil had fused with his Law Avatar when something interrupted his connection with the Law of Fire, deactivating his transformation. 

Somehow, that wave of invisible energy affected Baator's Law of Fire. Flames no longer burned and those who had yet to form Fire Essence and still depended on the plane's law lost their power.

Those powerful devils who created Fire Essence focused on the Yuru continent. Interest and greed appeared in their faces as they thought of the thing that could affect Baator's laws. 

Duke Krior's eyes depicted the utter shock he felt right now. He could still use the power of the Law of Fire, but the wave affected its ability to apply its influence on the outside world. 

The dwarf Duke saw his Hollow Sun Domain tremble before crumbling into nothing. Immediately, the Devil Duke's aura became weak, and exhaustion appeared on his face. 

'That eyes, it must have been a one-time use Pseudo Rank 7 Artifact. How could he obtain something like that!?' Hundreds of thoughts crossed Duke Krior's mind, but he did not have time to waste.

The Darkness Poison Duke pushed his power to the limit as he attacked the dwarf Devil Duke, ready to kill him.
