Abyssal Lord of the Magi World

Giant waves appeared in the  Spiritual Endless Ocean as the True Doomsday Body laughed maniacally. The light in the black humanoid's eyes grew clearer due to the new ego becoming more powerful.

Suddenly, two giant golden eyes appeared in the sky. They covered the entire Soul Celestial Vault, and they showed nothing but disdain as if everything was beneath them.

Those eyes made the True Doomsday Body freeze, and as he looked up, fear appeared in his face. The black humanoid still lacked a true ego and wisdom but recognized the entity that always forced him into submission.

Unlike the previous times he faced that existence, the black humanoid did not remain silent. 

"ROAR!" The True Doomsday Body roared to the sky as the madness in his eyes grew more potent.

Unfortunately for the black humanoid, that act of rebellion seemed to have enraged the entity in the sky. Golden lightning and mighty thunder covered the Inner Law Dimension as a golden humanoid descended from the Soul Celestial Vault.

The True Will honored his title of Soul Celestial Overlord as his presence resembled a heavenly existence, descending from the sky to punish the one who dared to rebel against his might.

Although he did his best to stop it, the True Doomsday Body could not stop himself from trembling when he saw the True Will. While both were existences made of Zatiel's Primordial Essence, only one had the will and ego of the entity who once stood above everyone else in the Prima Universe.

Despite the fear, the True Doomsday Body refused to surrender. The madness in his eyes kept growing, and he prepared to unleash another roar signaling his desire to fight.

"RO..." Before the black humanoid could even finish his roar, the True Will was already in front of him.

The immense pressure of the Spiritual Endless Ocean did not affect the golden humanoid. He displayed his ruthless nature by grabbing the True Doomsday Body's head and plummeting into the deepest part of the Inner Law Dimension.

In less than a second, both crashed into the Inner Law Dimension's base wall. 

The True Doomsday Body screamed, but with a crazy look on his face, he gathered all of his power and punched toward the True Will.

While the True Doomsday Body Path of Power granted a tremendous physical might, the black humanoid's offensive power by himself was not impressive. 

On the other hand, the True Will's purpose was to fight entities of spiritual nature. Not to mention that since Zatiel reached the Peak Star Breaker, the golden humanoid could be considered an entity in Early Rank 6.

Showing outstanding skills and capacities, highly superior to those of his enemy, the True Will dodged the True Doomsday Body's attack before unleashing a barrage of punches toward the black humanoid.

Every punch made the True Doomsday Body twist in pain, but his figure showed no damage, nor did the Primordial Essence that formed him.

The True Will's attack did not harm the physical aspect of the True Doomsday Body. Instead, his power targeted the will and ego forming inside the black humanoid. 

Punch after punch landed on the black humanoid, and the True Will did not stop until the last fragment of madness vanished from the True Doomsday Body's eyes. 

Only once the black humanoid returned to being without ego or wisdom did the golden humanoid let go of him and return to the sky, taking his position as Soul Celestial Overlord in the highest heaven. 

The True Doomsday Body, now free of the corruption of the Eldritch Universe's Will, adopted a meditative position in the bottom of the Spiritual Endless Ocean and returned to his training. 

Zatiel finally retrieved his perception from inside his Inner Law Dimension and relaxed. His face was a little pale, but excitement filled his eyes as he felt the effect devouring the True Self had in the black humanoid.

A True Doomsday Body fed on Star Consciousnesses and Origin Power. 

While an endless amount of Origin Power was available for the True Doomsday Body to consume, the number of Apocalyptic Star Heavens limited the times he could benefit from Star Consciousnesses, despite these having the most significant effect on the black humanoid's potential.

The reason for Zatiel's excitement was that devouring a True Self not only provided the black humanoid with a tremendous amount of soul force and Origin Power, but it also enhanced his foundation and capabilities.

This ability meant that devouring a True Self would increment the cultivation speed of the True Doomsday Body Path of Power while enhancing the might of the heavens and the power of the future stars sealed in them.

The chance of growing stronger would blind anyone else's reasoning, but Zatiel maintained calm. Before doing anything, he attempted to decipher the reason behind the True Doomsday Body's ability to devour a True Self. 

'The power that made possible the creation of the True Doomsday Body is the Absolute Unity Omega Law, and that cosmic force is the manifestation of the concepts of devouring and assimilation.'

From his birth until this moment, no external force had ever come into contact with his True Doomsday Body, so Zatiel immediately discarded this ability as something new. 

He believed that this devouring power was something the black humanoid could do from the beginning, but since Zatiel had never caught an Eldritch's True Self before, he had not found out until now.

'I initially thought that only Star Consciousnesses would be of use for the black humanoid due to their connection to the primal force that gives birth to all matter in the universe. I can only assume that my Omega Law's evolution during the last fight in Baator gave the True Doomsday Body the ability to devour a True Self. It makes sense considering the thing I faced in Nexus.'

After a few hours of analyzing the information and using all his magical knowledge, Zatiel concluded there was a 99% chance his hypothesis was correct. 

Now that he understood how it happened, Zatiel smiled as he studied how much a True Self helped his True Doomsday Body Path of Power.

'The benefits of Eldritch's True Selves to the Apocalyptic Star Heavens were not infinite as there was a limit that the black humanoid could devour before having to ascend to the next cultivation level. While they may not be enough to jump a Star Tier, they would undoubtedly help me reach each new Tier's peak instead of the bottom.'

Due to Zatiel jumping a Tier when he sealed his fourth Apocalyptic Star, this heaven only withstood an Early Tier 5 Star. The Neo-Demon thought that the next one would be at best at the Middle Tier 6, but with the help of the Eldricht's True Selves, there was a chance of sealing one at the peak.

Regarding the danger of the process, Zatiel also considered it for a moment but soon discarded it. 

The Neo-Demon did not take the Eldritch Universe's Will corruption lightly, but the effect was similar to what his True Soul would face, and he already knew how to handle that.

"Hahahaha, Ezequiel, this place is a true paradise for us." 

Zatiel began to laugh as he thought how superb the Prima-Eldritch Universe Final Battlefield would be for his cultivation. Not only would he obtain a Sacred Body of Laws superior to every other life form in the Prima Universe, but his fleshy body would grow monstrously powerful as well.
