Abyssal Lord of the Magi World

Zatiel gave the Primarchs a moment to analyze the information he just gave them before carrying on.

"Willpower is the most important and the hardest of the Cores of Existence to train. It is impossible to take the True Path and make your existence evolve beyond the Law Realm without it. However, tackling willpower first is only making things harder for you."

Under the Primarchs' gazes, the Five Cores of Existence formed a wheel with the golden humanoid at the zenith.

"The first Core of Existence that you should address is energy. Our Inner Universe contains a massive amount of forces. While improving its quantity is extremely hard once you reach Peak Rank 9, generating a qualitative change is more plausible. As a matter of fact, one of you already took that step forward." Zatiel's humanoids turned toward Salomon as he spoke that last part.

Salomon's eyes narrowed as he gave a slight nod.

"I manage to trigger a quality evolution in my energy. Using my Omega Law, I transformed all the forces inside my Inner Universe into a single power I called Dao Force. Honestly, I did not know its importance, but I did feel a change occur in my existence. It was as if my understanding of reality slightly morphed."

The Primarchs were surprised but also a little disappointed. It was clear that Salomon's path would not work for them, so asking for his help would not be of much use. Without wasting a second, they returned their focus to Zatiel, full of expectations.

"Now, once you have evolved your energy, it is time to tackle the body."

The sphere that represented the Inner Universe glowed, signaling the evolutive change, and then everybody saw how a pillar of plasma emerged from it and reached the black humanoid.

"You will use the new Rank 10 energy to temper your body or deploy body tempering techniques. As your energy has already evolved and fed your flesh and blood, it will only be a matter of time before another of your Cores of Existence enters Rank 10."

Issac and the other Primarchs engrave those words in their minds. None of them could stop themselves from smiling. Unlike the cryptic words of the Flame Imperator, Zatiel was showing them a systematic and structured approach into Rank 10.

"If any of you want to have an idea of the power that having two Cores of Existence into Rank 10 would grant you. A Nine Silver Stars of Origin Chrollo is a perfect example."

When they heard those words, the ones with the more significant reaction were the members of the Dark Tower Alliance. Chrollo managed to fight the three Primarchs simultaneously despite having to split part of his concentration into the Universe Will.

It was clear that with just two Core of Existence in Rank 10, they would become invincible among Rank 9 life forms.

More plasma channels emerged from the black humanoid and the sphere that contained the Inner Universe and connected with the blue humanoid and the cosmic force.

"Finally, it is the turn of the soul and Omega Law. As your body and energy enter Rank 10, your understanding of the myriad forces and laws of the universe will become stronger. You can also nourish your soul with your enhanced life force."

Zatiel waved his hand, making the blue humanoid and the sphere containing the cosmic force grow larger.

"Your soul is formed by Primordial Essence, the same component that creates willpower. Your Omega Law embodies your existence, affecting every part of you. Improving any of them will positively affect your willpower, and improving both will make that feedback even stronger."

The blue humanoid and the sphere containing the cosmic force glowed, marking their evolution, and generating plasma channels that connected into the golden humanoid.

"When Empyreal Primordial Chrollo triggered that illusory tenth Silver Star of Origin, I deduce that he managed to push another Core of Existence into Rank 10."

Every Primarchs was perfectly aware of Chrollo's power after igniting that tenth Silver Star of Origin. Even the nine Primarchs together could have barely matched the Empyrean Primordial.

"As for entities that have pushed four of their Cores of Existence into Rank 10, I am aware of three of them in the Prima Universe's history."

Shock appeared in the Primarchs when they heard that last information. Three individuals of the Prima Universe have already reached a level that could allow them to be at the front gate of Rank 10. They were all waiting to hear those names, and Zatiel did not disappoint.

"The first was possibly the most ancient entity in the Prima Universe and the hidden guardian, always waiting for the time to strike if necessary, the World Tree. The second was the de facto leader during the Cataclysmic War against the Eldritch Race, and possibly the only reason the Prima Universe did not perish during that war, the Champion of Justice and Order."

Zatiel did not speak the next name immediately, but all the Primarchs had an idea who was the third individual that managed to evolve four of their Cores of Existence into Rank 10.

"The final one was the Nightmare of Dis, the man that wreaked havoc on Abyss and Baator, the Incarnation of Death and Destruction."

Those names were sources of legend and myths, even for Primarchs. When Issac and the others heard them, they all exchanged glances. It was highly likely that one of the names Zatiel just spoke was his previous identity.

Of course, none of the Primarchs would question the Neo-Demon about it. There was no way Zatiel would answer it, and they would only be making a fool of themselves.

"Now, once you have improved four of the Five Core of Existence into Rank 10, it is time to evolve the most important one, willpower." Zatiel's voice became solemn as he spoke those words. It was clear to everybody how important they were to him.

"It is only through our willpower that we can break the limits of the universe and become entities that stand above reality!" The Neo-Demon's eyes burned with fighting spirit, but he released a small sigh after a few moments.

"However, that is so incredibly difficult." Zatiel felt a wave of melancholy assault him as he spoke and remembered how hard he fought in his past life to no avail.

He did not let those emotions affect him for long and carried on with his presentation.

"Now, if you cannot push your willpower into Rank 10, but your other Cores of Existence manage to evolve, you can take the Fake Path."

Issac and the others' attention spiked when they heard that. None of the Primarchs were so arrogant as to think they would definitely surpass the Champion of Justice and Order and the Incarnation of Death and Destruction.

Therefore the best choice was the Fake Path. Just by its name, they already deduced it was inferior to the True Path, but it was something that would surely make them more powerful.

"Those that take the Fake Path fuse their minds with the Universe Will. That will allow your willpower to jump into Rank 10 and surpass the Law Realm. However, taking that path is a literal dead end, as your ego would slowly erode, and once the Epoch ends, you will accompany the universe in death."
