"Your soul?"
Ruby looked at Ybur hesitantly, "Didn't I tell you right when you first opened your eyes? Your body has been infused with Immortal Elixir! The Immortal Elixir is the blood of a god, a fragment of a deity, possessing the possibility of creating all things. Of course, your soul came into being this way!"
Ybur was skeptical, "Really?"
Divine Blood is too much of a catch-all answer, especially when it's the Sun God's Divine Blood. After all, the Sun God is the former supreme ruler of the Dream Realm, having achieved godhood thrice, and the entire Awake World was created under the guidance of the Sun God. It's not at all impossible that a soul could be born from the remnants of such Divine Power...
Ruby explained, "To put it simply, I used a fragment of my own soul as the seed, while the Divine Blood is the fertile soil that nurtures everything. I planted the seed and then used some... um, fertilizer?"
