There was war and destruction going on around him as demons fought gods. But he simply stood in the sky while his body began producing light.
The golden light within him was leaking out through his skin. His skin began to melt. Even his horn was not spared. It is like there was a fire burning within him. This fire is reforging him from the inside out.
He said to himself in anticipation, "The resistance of the mark of sin has finally been completely resisted. It is mine now."
The source of light within him is the mark of sin. The crown of dominion has acquired enough power through the sacrifice of powerful items to overcome the resistance of the mark of sin and cause his evolution through brute force. It is an unconventional way for demon kings to evolve.
Normally, the mark of sin contains enough power to make a demon evolve to the level of a demon god. They can harness this power by fusing with the mark of sin. What's stopping them from achieving this is the resistance of the mark of sin.
Demon kings can overcome these problems by comprehending their sin enough to overcome the resistance of the mark of sin. He, on the other hand, has yet to fuse with the mark of sin because he hasn't comprehended the supreme law of Chaos. However, he has acquired enough power to steal the mark of sin from the abyss and evolve without its permission.
His state of existence is evolving now that there is no resistance to digging out the power within the mark of sin. The immense power capable of producing a demon god is now fusing with his existence.
His existence changed as he evolved. His separate soul and body fused to become one. He became a vessel for the mark of sin and the Chaos energy that it produces.
His changes ended there. He was supposed to become one with the energy produced by his mark of sin too, but he is not a demon god. He didn't fuse with the mark of sin, so he can't fuse with Chaos energy yet.
He felt the changes in his existence, and he couldn't help but be disappointed. "This came too late."
The fire burning within him is the power from the mark forging his existence into a suitable vessel for Chaos. In the past, it was just his body that could bear Chaos energy; now his soul can bear Chaos energy too.
His soul has finally gained innate immunity to chaos energy, so he doesn't need soul force or the concept-like defense around his soul to protect him anymore. Unfortunately, this change is a waste because he doesn't need it anymore. He had found a way as a fledgling to bear the power of Chaos energy. That's how he was able to survive.
He had to change his soul with the law of the soul so that he could survive. Unlike what he did to survive, this innate immunity has made him capable of wielding Chaos energy in all its states.
So this innate immunity is better than the previous resistance against Chaos energy where his soul wouldn't be corroded as long as he was able to match Chaos energy in strength.
Not only that, his entire existence has become more attuned to chaos so he is capable of sensing and comprehending the Supreme Law of Chaos on his own.
These are all great, but anyone in shoes will be disappointed too. It is true that no demon should have an affinity with the Supreme Law of Chaos, so he is unique, but its effects came late.
He could already sense the law of Chaos as a demon king because of the effect of the shard of power, and he could resist Chaos thanks to the law of the soul.
So all these changes are too late. It would have been better if he had immunity to Chaos energy as a fledgling. He wouldn't have had to suffer for 50 years.
At this point, the affinity for Chaos doesn't serve any purpose apart from informing him that only beings like demon gods should be able to withstand Chaos energy without help and can comprehend it if they come in contact with it. Unfortunately for them, by that time, they already had their own false law of Chaos.
This has made it clear that he isn't supposed to exist. It is something he knew before since a demon fledgling shouldn't have Origin essence and shouldn't be able to withstand the law of Chaos that Origin essence attracted. So he is a rarity unique to the void universe.
He said in understanding, "I don't blame GREED. I would try my all to grab myself too if I were a demon god."
Now he understands just how strange and peculiar he must have looked to the demon gods when they sensed him. He had energy that was similar to theirs, but he wasn't a demon god. If they had grabbed him, they would have been able to get access to the true Supreme Law of Chaos through him.
This is why the demon god GREED wants to get him and why he has been on the run for so long. But he doesn't blame GREED for being greedy. It is something he would do, considering how greedy he is too.
The difference between the demon god GREED and Legion is that Legion doesn't need to grab a unique being in order to get their power. Legion can emulate the unique ability they want and go further to improve it so that it doesn't have any weaknesses and becomes something unique themselves. It is how they reincarnated into a demon and became something that demon gods envy.
"What else is there?" he muttered. "This can't be all."
He tried to move his body and use his power to find out the full extent of his evolution. He found out that even though he didn't become one with his energy the way demon gods do, his evolution was not a total waste. He got more than affinity with True Chaos.
