Instead of directly answering Neo, Nyxtharion asked another question.
"What do you think happens when a God keeps ranking up?"
"...?" Neo frowned. After thinking a bit he said, "They grow stronger."
"Yes, that happens too, but that is a byproduct.
"When Gods keep ranking up the main changes in them is the increase of 'existence level', and the quality of energy type they wield.
"'Existence level' is what everyone calls Stage 1, Stage 2, and more.
"'Energy type' is generally the 108 basic elements. At one point, each God has to choose between two different paths.
"They either follow the teaching of their element, and keep ranking up to become an Elemental Supreme.
"Or, they change their energy type. They would fuse new understanding into their element, and create a new element over time.
"This is how Shadow Element was born from Darkness Element, how Blood Element was born from Water Element, and how several more Elements were born.
