Soverick became the jewel of the plane. He fulfilled his purpose and went beyond it. That moment when he was marked by the plane, Legion was also marked because of their connection. A halo appeared in all of Legion's clones except Legion-1 who is already an Origin god. That mark appeared within Aeternus' soul and from it came origin energy or mana if he needed it.
The supply of infinite origin energy caused his production of soul energy to escalate to an unprecedented level. The chaos energy was being pushed back. His future started to look up. But only that, the pressure from chaos energy will continue to increase, which means he will need more and more origin energy to hold it back. He doesn't plan to allow that.
He doesn't want to let his life be reliant on some charity. What if the energy supply isn't truly infinite? What if something happens to Soverick or he loses the supply of energy? Then everything will end for legion-3. Still, the improvement gave him more room to improvise. So he tried something that the first legion clone to be born created.
He began to weave the law fragments of the law of chaos with death, darkness, fire, and soul into something similar to a concept while he imprinted them on his soul. In a way, he is modifying his soul. It is a painful and dangerous process.
He used the corrosive properties of chaos energy as a surgical blade. Chaos energy is obviously strong enough to damage his soul, so the challenge lies in controlling its effect to what is needed. Then he carved grooves into his soul in which he placed the arranged law fragments to form tattoos that resemble the network of the law matrix.
The combination of laws he had been using was catalyzed by the origin energy into crystalizing into forming a concept with his soul as the foundation. Demons can't use laws, which means they don't have concepts. He isn't a true demon. He has an Origin soul. Even so, Origin souls will remain impervious to the influence of a concept unless there is an origin essence. Thankfully he had a bead of it given to him by Legion-1 before they all reincarnated.
His soul began to absorb the created concept and started to evolve. When it was done, his soul became able to transform chaos energy into soul energy on its own without being damaged by the corrosive properties of chaos energy. His true name changed to accommodate the change. He became ETERNAL AND CHAOTIC ENVY. His part of the contract with the realm lord also ended immediately. Chaos energy has stopped bothering him so the deep-level scanning stopped. He also became able to move his body for the first time in over 40 years, all thanks to Soverick.
He said as he rose from the ground. "I guess it is time for me to earn my keep and fulfill my aim."
Aeternus' aim was planned when Gehaldirah came to the demon realm. He had gotten some critical information from the memories of the demon lord that wanted to possess him. He got to know that when a demon advances to become a demon god, it can evolve into something called a world-ender.
He didn't have much information about world-enders back then but his research showed that demons can't evolve into this creature on their own, they need a certain something that the will of the abyss gives them. That thing is called chaos blood.
It is almost similar to how Sovereigns need origin essence to become Origin gods. Except that demon gods are as powerful as origin gods and chaos essence is much rarer than origin essence and more dangerous.
Later on, he found out that world gods will do anything to get this Chaos blood. They call it chaos essence. When combined with Origin essence can be used to create anything. It was enough to make Gehaldirah set his mind on it. But further information that he got from the tower of heaven's library revealed that the world enders are one of the weaknesses of a world god. So now, he is bent on becoming a world-ender. That's why he wasn't willing to give up at all.
He began to review his resources and his state of existence. He had undergone unprecedented changes unseen in demons. His body and soul may have survived the struggle with chaos energy but they have also been skewed because of its influence.
"It's like a body of law. It is even complete." He commented on the state of his body.
His body was odd. He was thin, almost bare bones. His claws stretched from his hand like blades because of his receded skin. Black smoke was coming from his body and it was corroding the environment. It created a hazy cloak around him that obscured his figure and made him look bigger than he should be, more dangerous too.
It wasn't a smoke screen in the metaphorical sense. He really is dangerous. His thin body is as hard as metal. He might be lacking in strength but his blades and the chaotic energy flowing through him made him something not easily messed with. He looked like a wraith made of black flames. Fledglings had avoided him when he looked normal, now they will run away as soon as they sight him.
Still, that isn't the strangest thing about him.
Demons have something similar to a mana body and later on when they become stronger, they possess something like a transcendent body. But he has something similar to the body of law.
It is probably due to the influence of his soul, its evolution, and the chaotic energy he evolved with. A body of law signifies a bloodline. Demons have bloodlines but it is the lowest kind, that of a transcendent. So it isn't eternal and it degrades. Their bloodlines affect their sin. But he has already acquired something better. His sin of chaotic envy is way better than any of the sins he knows about.
