Abyssal Lord of the Magi World

A dark purple aura emanated from Zatiel, and thunderclaps could be heard from his body as his figure began to grow and muscles bulged out. From his elbows and knees, bone spikes jugged out, and flaming black runes were engraved in them.

Fire emerged from the Eye of Life and Creation, Eye of Death and Destruction, and Rebirth Eye. The power in each one of them grew immensely, and their innate abilities were pushed to the next level. 

The white wings in the Neo-Demon's back also grew in size, and each crystal feather became extremely sharp.

Doomsday Incarnation was the unique ability of the Neo-Demon race. The increase in power that it granted could match or surpass the boost of a Law Avatar. It stimulated the full potential of the Neo-Demon's body and bloodline, and only in this form would the abilities granted by the True Doomsday Body can show their true might. 

The strength of the Doomsday Incarnation depended on how well developed was the True Doomsday Body's Path of Power and the power of the Neo-Demon's bloodline. However, this impressive ability had a side-effect that was born due to the power it was used for its creation.

The transformation ended in an instant. As strength filled every cell of Zatiel's body, something else came with it. 

The Neo-Demon was not able to stop himself from releasing a mighty roar. His dark purple aura burst and spread in every direction. 

"ROOOOAAAAARRRR!" 

They say that while dragons' roars could scare mortals, it would only make devils and demons laugh, but the roar of a Doomsday Incarnation made all those devils who heard it tremble as terror filled their hearts. 

The only ones who were able to maintain control over their emotions were the Devil Lords. However, a solemn expression appeared in the duo when they felt Zatiel's aura. 

It was an aura that could infuse horror even in Rank 4 Fiends, an aura that depicted a will that sought to destroy everything and slaughter everyone, an aura that could only be born of the overwhelming desire to bring everything to an end and submerge the universe into complete emptiness.

A small smile appeared on Xenia's face as a plan began to formulate in her mind. As for Zitu, he only made his energy increase and descended with even more power.

In Zatiel's soul dimension, a red light began to appear in the eyes of the True Doomsday Body. A golden light permeated the dimension in the next instant, as the True Will used his power to keep the black humanoid's ego in check. 

The wild and savage instincts that attempted to invade Zatiel's mind dissipated thanks to the power of his True Will, but the desire to bring doom into the universe remained.

He did not have a problem with this feeling since it was the right mindset in a battle. A Neo-Demon must become an embodiment of death and destruction the moment they go into war. The race must act like a heartless machine whose ultimate goal is to deliver annihilation to those marked by their Ancestor. 

Zatiel was able to adapt instantly to his new power. His eyes were filled with the murdering intent as he saw the Rank 4 Devils trying to escape his domain.

The Neo-Demon displayed the full power of the Absolute Solar Yang True Doomsday Body. The flames in the domain transformed into a dark golden plasma that was hotter than the core of a Low World's sun. 

The plasma was not only hot but also hard. The devils felt as if hundreds of mountains were crushing their bodies in every direction, and there was nothing they could do other than use their full power to resist the destructive power of the plasma.

A duo that had the face of a beautiful woman and the body of an infernal wasp was using all their power to resist until their leader's arrival. Unfortunately, the thing that appeared in their sight was the Undying Leviathan. 

The creature swallowed them whole before piercing the earth and disappearing from everyone's sight. 

A Rank 4 Hell Cockroach saw with horror how his comrades were eaten. He was about to burn his life force in the hopes he could gain enough power to escape when an index finger pierced his skull. 

Dark purple flames invaded his soul dimension. He was not able to do anything while the Neo-Demon swallowed his body and True Soul. 

The last devil had managed to ignite his life force, but he was barely able to move half a meter before an arm pierce his chest, and just like his friend, his body and soul were devoured. 

After having consumed the bodies and True Souls of three Rank 4 Devils, Zatiel's felt his bloodline along with Rebirth Eye return to their full power. 

The Neo-Demon focused on the Devil Lord that was about to clash with him and whose face was filled with rage. 

He used the power of the Absolute Solar Yang True Doomsday Body to compress the flaming plasma. 

The devils in the city's walls saw a world-ending meteor clash with a dark golden sun. One was almost one hundred thousand meters large while the other only fifty meters in diameter, but no one could tell which one was stronger. 

An explosion of red and dark golden fire occurred when the two apocalyptic entities clashed. Hundreds of kilometers were devastated in an instant, killing all the lesser devils that had not already succumbed to Zatiel's domain. 

The fire also reached the city's walls, but the force field protected the residents, or else, only those at Rank 4 would have survived. 

Earthquakes and storms appeared after that cataclysmic explosion and the duo that caused it vanished. 

Terror and envy appeared in the lesser devils as they saw that power. Despite not having taken their eyes away from the clash, the duo moved too fast, and they only saw an explosion. 

Countess Xenia saw how Zitu's hooks clashed with the Neo-Demon's sword and bone spikes almost ten times in an instant. Neither of them contained their power, which resulted in that blast. 

The Devil Lord and the Neo-Demon were not stupid, and after the initial crash, they immediately broke space and were expulsed hundred of thousands of kilometers in the sky.

A vicious and ruthless light appeared in Xenia's eyes as she saw the two monsters fighting. A sweet fragrance began to emanate from her body, and slowly, and without anyone realizing it, it spread through the entire city. 

The fight between the dark golden sun and the world-ending meteorite could only be described as cataclysmic. The shockwave of their impacts could devastate everything in a radius of five hundred thousand meters. 

The body of the Devil Lord was countless times larger than that of the Neo-Demon. However, Zatiel's attacks could cover tens of kilometers and affect his opponent's consciousness, making the difference in size irrelevant.

Zitu's arms have transformed into six giant whips with sharp hooks at their end. They attacked with an amazing speed and dexterity, all of them charged with the power Law of Fire and Law of Earth, giving them weight and heat. 

The dark golden plasma around the Neo-Demon worked as a shield that slowed down the Devil Lord's attacks, allowing Zatiel to respond with his sword, bone spikes, and sharp wings.

The Devil Lord's attacks were powerful and fast, but his domain over long-distance spells was null. Zatiel took advantage of that and constantly fired beams of energy from his eyes that rot Zitu's skin, and filled his body with deadly energy. 

Three beams of energy had landed in the Devil Lord's chest when all of a sudden, Zatiel felt an immense sense of danger. Zitu threw his flaming body forward, shrinking the distance between the two, and his whips attacked from every direction. 

The Neo-Demon's eyes narrowed as he pushed his body up, parrying four of the whips and using his wings to protect himself from the last two before launching an arc of blue and purple fire to the Devil Lord's eyes. 

The arc of fire was too fast and the distance too little. Zitu detected the danger and knew he was not able to dodge the attack. Anger appeared on his face as he activated an artifact that was hidden inside his body. 

A black membrane filled with howling faces covered the Devil Lord's gargantuan body. 

Zatiel was not surprised that Zittu had a life-saving card since he was a Law Engraving existence and a Devil Lord. However, he detected that while the membrane indeed increased his enemy's defenses, its main function was to protect from illusions and soul invasion spells. 

The arc of blue and purple fire could have destroyed a considerable portion of the Devil Lord's head and infected his soul dimension, but the membrane completely neutralized it. 

The Neo-Demon was not able to continue with his attacks since the whips clashed on him. Zatiel used his wings to protect himself, increasing the number of wounds they have. 

'Dammit!. Defending from that attack used almost all the energy in the Illusion Shield. Fightin Xenia without it will be too dangerous. This foreigner not only destroyed my army but also ruined my plans.' Zitu was furious, but he did not reach where he was by allowing his emotion to dictate his actions. 

His injuries were not life-threatening and did not diminish his battle power at all. His vital organs and consciousness were fine, and while Zatiel's energy was bothersome, he could easily keep it in check as long as he maintained One with the Law. 

While the Devil Lord was thinking whether or not to continue attacking the wounded Neo-Demon, his instinct screamed danger and detected two new enemies appear behind him.
