"What did you learn in the first place that even made gods feel threatened?"
Her gaze sharpened like a blade. "Immortality."
Oliver almost jumped. "Immortality?!!"
"Yes. Immortality," she said calmly, as though it were the simplest thing in the world. "When I delved deeper into body-modification runes, I reached the pinnacle of creation. The point where the soul, body, and mana could be forced into an eternal circuit."
Oliver blinked in disbelief.
"I created a penta-layered array carved into both soul and flesh," she continued, her voice taking on a rhythm like a scholar lecturing. "It consisted of five fundamental runes. Together, they formed what I called the Immortality Circuit."
She raised her hand as if tracing invisible glyphs in the air.
"First, the [Rune of Eternum]. It binds the soul permanently to the body. Even if flesh is destroyed, the soul acts as a blueprint to rebuild it."
