Sacrificing the Late Rank 9 Yellow Avatar and a world full of Peak Rank 3 avatars just for entering the Soul Realm without shackles might sound crazy for many but not for the King in Yellow. He refused to accept limitations and sought to explore and see everything, even the space beyond the Cosmic Wall!
Other than incredibly smart and scheming, the other word that could describe the King in Yellow was curious. For him, the Law Realm could not be the end!
The rise of the Final Gate generated a great change in the Eldritch Universe, as the artifact stole origin power from the universe and sent it into the Prima Universe. That meant there was not enough for the current population, despite the Cataclysmic War having reduced their number immensely.
The wound sustained during the last battle forced the Great Old Ones to enter a long slumber, but before that, they issued a command to the entire Eldritch Universe.
Start a massacre like no other.
It was a simple command but one that triggered a wave of genocides that covered entire galaxies. That period of time was known later in history as the One Billion Years Carnage.
During the One Billion Years Carnage, it was normal for even those at the Law Realm to perish, and any Soul Realm Eldritch that dared to come out of their hiding would die without a doubt.
However, there was one Soul Realm Eldritch that not only did not hide full of fear but prospered during that time. Of course, that was no other than the King in Yellow.
The King in Yellow used his cunningness and wisdom to overcome all obstacles in his path. It did not take him long to once again rise to the Law Realm, and due to his talent and battle power, that was enough for him to secure his life and travel the Eldritch Universe openly.
Nevertheless, while that was enough for him not to fear the other Eldritchs, the King in Yellow knew he was not safe as the threat of the Great Old Ones always loomed over him. Unless he wanted to hide forever, they would learn about him and find out the uniqueness of his True Self.
There was no way the Great Old Ones would let him live after that, and he was sure they would make an example out of him, so his death would not be quick.
He was in a race against time and needed to become strong enough before the Great Old Ones woke up from their slumber.
Millennia went by, and the King in Yellow's cultivation finally regained the level he achieved with the Yellow Avatar. Without a shackled True Self, it wasn't hard for him to evolve his Energy Core of Existence into Rank 10 and become an Extreme Rank 9 life form.
It took him less than a century after the evolution of his energy for the King in Yellow to evolve his Body Core of Existence. That made perfect sense since the True Self Path of Power focused on the body center of power, and the King in Yellow's foundation was flawless.
However, things became much more challenging when it was the turn of the Soul Core of Existence. The Eldritch Universe's cultivation heritage regarding the soul center of power was not well developed, something that the Great Old Ones actually enforced since none of them wanted an Eldritch that could somehow break free of their spirit control.
Luckily, the King in Yellow had already anticipated this point, and he made sure to gather knowledge from the Prima Universe during the Cataclysmic War. Specifically, he stole it from a race known as Mind Rulers, known for their soul force mastery.
It took him more than ten times the time and effort he put into the Body Core of Existence, but the King in Yellow managed to evolve his Soul Core of Existence into Rank 10.
Next came the evolution of his Omega Law. Unlike the power that the Yellow Avatar mastered, the King in Yellow's Omega Law did not use the Law of Cause and Law of Effect as the basis for his Omega Law.
Those were the Principal Laws of the Eldritch Universe, and no matter how hard he worked on them, he could never master them to a higher degree than the Great Old Ones, who were, by essence, laws made flesh.
That is why the King in Yellow used the Prima Universe as inspiration for his Omega Law, mastering the power of the Law of Space-Time.
Of course, the King in Yellow did not just mimic the Prima Universe's Principal Laws, as he used his own understanding of them and bound both laws through the power of karma. That is how the Karmic Space-Time Omega Law came into existence.
It was a power greater than the mere sum of their parts, generating a sublimation of space-time forces.
Once his Soul, Body, and Energy Cores of Existence nurtured his existence long enough, the Omega Law Core of Existence also evolved into Rank 10. That transformed the King in Yellow into a monster that no one in the Eldritch Universe could face on their own.
Becoming a Fourth Evolution Extreme Rank 9 life form was a feat only a few could state to have achieved on their own, and he was the only one in the multiverse that did it in a super universe where his entire race were slaves.
Unfortunately, the King in Yellow understood that his current power was insufficient. As the Herald of the Great Old Ones, he knew their capabilities.
The Great Old Ones' Leader, Azathoth, was also a Fourth Evolution Extreme Rank 9 life form. His battle power was not as high as that of the World Tree or the Champion of Justice and Order, but his vitality was virtually endless.
The King in Yellow knew that if he faced Azathoth alone, he could, at most, end the battle in a draw, but there was no way the other Great Old Ones would just sit by and do nothing.
He needed a power that could allow him to face all the Great Old Ones together, but just like every Fourth Evolution Extreme Rank 9 life form before him, he found himself unable to cross the final obstacle and enter Rank 10.
Unlike all other Cores of Existence, there were no treasures that could nurture the Will Core of Existence, and you could only depend on yourself.
The King in Yellow could feel that his willpower had risen to a shocking level thanks to the evolution of his other four Cores of Existence, but he still could not find a way to improve this one into the next Rank.
Given enough time, the King in Yellow was sure he could find a way beyond that obstacle. He knew how powerful his mind and determination were, and not even for a second doubted himself.
However, time was not exactly something he had on hand. The Great Old Ones' awakening would happen soon, and he could very well face the entire Eldritch Universe by then.
After a long period of contemplation, the King in Yellow decided to look into the Eldritch Universe's nucleus for a way to survive. He investigated it a lot when planning for the Origin Eldritch Curse's plan and knew an incredible power was hiding in it.
The King in Yellow also knew that the nucleus contained immense danger, but he sacrificed everything he had once for endless potential. What would be the point of it if he did not use it.
