Abyssal Lord of the Magi World

After a few seconds, Eon Six's heartbeat returned to normal, and the earthquakes that threatened to split the canyon apart vanished. 

"I train a unique body-refinement Path Technique that requires the heart, bloodline, and soul of powerful fiends named Fiend Sun Heart. I came to Baator with the sole purpose of obtaining a living Duke's heart and a piece of his Primordial Essence." 

Eon Six was very straightforward, and he deduced that an old monster like Zatiel would only need to see his artificial heart once to know if he was telling the truth or not. 

Zatiel remained silent for a moment. It was clear to him that Eon Six wanted to obtain his assistance in killing a Devil Duke.

"Why don't you ask your father or brothers to help you with this task. I am sure that with their powers, it would be easy to trap a Devil Duke or even an Archdevil alive."

The moment Eon Six heard Zatiel's words, he immediately shook his head.

"The Infinite Space-Time Supernova Eye can fight with even the strongest of the living Archdevils, and it would only take a second for him to collect all the materials I would ever need for my cultivation. However, if I follow that path, I will always be garbage that depends on others to solve his problems." Eon Six's face showed the immense resolution behind his words. 

"I need to solve these problems on my own and enhance my destiny. When the time comes that I face an obstacle so vast that not even my father can help me, my spirit will not break, and I will be able to find a way out on my own. I am offering you an alliance where we will combine our power to achieve a task that will benefit both of us."

The Neo-Demon agreed with Eon Six's words.

"You were taught well. Depending on others for everything will limit your path and make you a mediocre person who could never equal someone who struggled all his life to obtain power and freedom." Zatiel could have obtained from Ivar the Flawless many Law Bloodlines and resources for his trusted allies, but he did not. 

They must struggle and get them with their own power, or else they will be useless when the time comes to face a threat too big even for the Supreme Overlords of the Prima Universe.

"How much of the Duke's Primordial Essence do you need?"

Eon Six smiled when he heard that since it meant they were in business. 

"Less than a fifth. The core of the Fiend Sun Heart Path Technique is the Duke's heart and the Demonic Bloodline that evolved for more than one thousand years inside it."

"If that is the case, I am willing to partner with you. I need the rest of the Primordial Essence and what remains of the corpse."

"You can keep the corpse, but I will take the space ring."

"I want the chance to explore the ring and obtain one item of my choosing." 

The corpse of a Fiend Duke was a great treasure and usually more valuable than the resources a Rank 6 Devil Lord could collect, but Zatiel wanted to explore his belongings in case there was something unique.

Eon Six understood the reason behind Zatiel's request, and after a moment, he nodded.

"I accept the conditions. The Darkness Poison Duke intends to enter the battlefield after finishing an artifact meant to reduce Duke Krior's battle power. He will be ready in twenty months at the earliest, so we must hurry up."

If the Neo-Demon and Supernova Race man worked together and went all out, they could face a Rank 6 life form that lacked an Inner Law Dimension, but a Devil Duke is easily three times stronger than that, not to mention they have all kinds of life-saving cards. 

They began to discuss the plan, and after a few minutes, they left the continent.

.....

In the 5th Layer of Abyss, a demonic dragon covered in fire and lightning fought a Chimera Demon.

The Demon Count was four hundred thousand meters tall, with a goat's head, the body of a lion, and a snake as a tail. 

Explosions filled the sky as the fire-lightning demonic dragon and the Demon Count attacks clashed. 

The Chimera Demon had the upper hand since he surpassed his enemy physically and in spells' power, but the dragon's flames burned with an intensity so high that they pushed his attacks to a higher level.

The demonic dragon also channeled the power of the Law of Lightning to improve his speed. He used it to either dodge the Chimera Demon's attacks or improve his momentum and strike with a greater force.

Rage appeared in the Chimera Demon's eyes and opened his mouth as he prepared to release a torrent of poisonous green fire.

The fire-lightning demonic dragon's eyes shone with a peculiar light, and he smiled before roaring.

"ROAR!" He channeled all of his power into a beam of lightning-fire that clashed with the Chimera Demon's attack.

The poisonous green fire and lightning-fire clashed, unleashing thunder and toxic gales.

Happiness appeared in the Chimera Demon's eyes as the attacks collided. His energy pool was larger than his opponent, and soon the torrent of green fire would overcome the lightning-fire beam and severely wound the demonic dragon. 

However, the next second, horror appeared on the Demon Count's face as his instincts screamed danger, and he felt that an individual covered in ice-fire appeared behind him. 

Sophia raised her hands and conjured a giant spear of ice-fire above her head.

The threat of death made the Chimera Demon go wild, and he began to burn his life force to increase his power. The torrent of green fire grew more potent, and it would overpower the lightning-fire beam in a matter of seconds.

Ten powerful magic shields appeared behind him, all of them capable of resisting a spell with 4th Engraving Stage power.

After seeing the enemy's defenses, Sophia's eyes narrowed, and the crystal with white liquid fire in her forehead glowed. 

The white liquid fire began to surround the giant ice-fire spear. It consumed an immense amount of energy, much more than what a regular Rank 4 Neo-Demon could have, but Sophia had chosen the Endless Chaos True Doomsday Body, so her energy pool was immense.

Absolute terror invaded the Chimera Demon's heart when the white liquid fire appeared, but before he could do anything, Sophia launched the ice-fire spear.

Despite the power of the magic shields, the white liquid flames ignored them and allowed the ice-fire spear to pierce them and finally penetrate the Chimera Demon's chest before exploding into a blast that froze the Demon Count's body and soul.

Sophia implanted a Sealing Rune over the frozen Chimera Demon, making sure his True Soul couldn't escape, before storing the body in her space ring.

Kylo appeared beside the Neo-Demon the next moment. He was exhausted, but the wounds on his body were shallow and would heal in less than a day. 

Of course, things would have been much different if he had fought the Chimera Demon alone. 

"With this Chimera Demon, we have captured twelve Demon Counts and eighty-seven Rank 4 Demons. After reaching fifteen of the first and one hundred of the second, we will enter secluded training and strive to enter the Law Engraving Rank." Sophia spoke after analyzing their harvest and current strength. 

Kylo thought for a moment before nodding to the female Neo-Demon's words. Thanks to their draconic lineage, their cultivation's speed was fast, and they have already reached the Fifth Origin Cycle and sealed three Apocalyptic Stars.

Sophia's battle power reached the bottom of the 4th Engraving Stage, and her offensive power crossed to the 5th Engraving Stage if she used the Law of Pure Emptiness in the white liquid flame. As for Kylo, his battle power reached the 3rd Engraving Stage, and his fire had Pseudo 4th Engraving Stage offensive power.

The duo knew that increasing their battle power without advancing to the next Rank in one of their Paths of Power would be almost impossible. 

As they flew back to their castle to rest before hunting again, Sophia felt something and took a metallic tadpole from her space ring. 

The metallic tadpole was a particular artifact that Dante obtained from Hades, and that allowed the Elder Brain to send messages despite being in different planes.

"Sophia, Kylo. You two must return to the Beta Heavenly World in three years." The metallic tadpole opened its mouth, and the Neo-Demons heard Dante's voice.

"Husband already finished our Animax Soul Runes?" An excited expression appeared on Sophia's face.

An Animax Soul Rune would momentarily improve their strength by fifty percent, pushing their battle power one Engraving Stage higher.

Unfortunately for the woman, the metallic tadpole shook its head.

"This order doesn't come from Father, but from the Supreme. He is not only calling you two but Father's entire inner circle."
