My previous beautiful and endless Spiritual Sea was completely annihilated, leaving only my unscathed Throne and pure chaos, literally.
I already suspected that the Chaos Pearl contained the pure law of Chaos, hence the name, and wanted to experiment with it. I didn't expect that after fusing with my NE, it grew powerful enough to blast my NE-infused Spiritual Sea.
A cultivator would be completely brain-dead or regress to the Foundation Establishment realm at best but to me, it was a small annoyance at best. Even if a pure Chaos law strengthened by NE could destroy my Spiritual Sea, it couldn't erase it as it was still NE at its core.
That was what the chaos was made of, infinite pieces of my spiritual sea and the nascent soul that was supposed to be born from my core. It would take a long time to rebuild the two but turning pure chaos to order by hand sounded like a good challenge.
Over the next 10,000 years, I pieced my spiritual sea and nascent soul back together piece by piece. Somehow the process had changed and fused the two things into a familiar thing.
My Throne was still standing proud and glorious but the spiritual sea and nascent soul were nowhere to be seen. They were still exactly where they were supposed to be, the sea below and the soul above the throne, but their form changed.
They both turn into Nothing.
I'm guessing the Nascent Soul tried to copy my true form instead of my physical like it was supposed to which might have led to the Chaos law acting so violently. After being rebuilt from my Spiritual Sea, Nascent Soul, and pure Chaos law, the two changed into pure Nothingness, reflecting my nature once again.
I am Nothingness and will always be. Nothingness was my body, soul, and mind.
Besides the symbolic stuff, it also had another important meaning. Since Nothingness was now part of my cultivation path, as long as I continued cultivating, Nothingness would grow with it.
What kind of concept was that? Nothingness was already infinite, absolute, and supreme but now I could actually make it even stronger.
Just Nothingness' passive erosion now was already enough to make Azathoth use his full power to resist it, I'm afraid if the Nothingness grows even stronger, I will accidentally erase that guy one day.
With my 'Nascent Soul' completed, I now had two realms before me that would make Nothingness grow beyond its current absolute power. I honestly have no idea how I could describe this level of power.
The Nascent soul was supposed to be born as a baby version of the cultivator and then slowly grow to the cultivator's age during the Soul Refinement realm but how was I supposed to do that when mine had neither form nor age?
I tried feeding it energy like a normal person but it was either rejected, erased, or was already part of Nothingness. Since NE and other energies didn't work, I continued looking for almost a month.
It turned out that the answer was much simpler. The Nothingness inherited some of the traits from the core it was born from. Don't ask, it was paradoxical and made no sense.
My core somehow created the Nothingness but at the same time, a different type of Nothing was already around before it. Instead of some reality-breaking apocalypse or rejection, the old and new Nothingness just became one.
While the old Nothingness just erased and turned everything into Nothing, this new version had the same traits plus devouring. At the same time, the Nothingness remained the same as always, and only the Nothingness inside me began to devour.
As I said, it makes no sense, so don't even try to understand it, being unexplainable was part of its nature, and by extension mine.
Turns out the method for refining my 'Nascent Soul' was to feel it laws of reality. At first, I only fed it the law of fire from a neighboring world but its hunger grew exponentially the more I fed it.
First, it was just the basic laws, then some stronger ones until it ultimately ate the entire world, materials and laws.
At first, it was just one mortal world, then two, four, and so on. In just a few days, all mortal realms except the one I was on were erased and devoured. It would have eaten this one too if I hadn't used some of my real power to create new laws to feed it.
True to its paradoxical nature, I learned that while I fed and grew it, it grew stronger but at the same time it didn't. It could grow as much as it wanted but it was already absolute and it would make no difference.
Contrary to the plans I made over 10,000 years ago, I exited seclusion before reaching the Ascension realm. I just saved this world because I had an ongoing experiment and some other bastard children of destiny.
It was time to see them. I wonder how the zombies are doing.
