"Immortality?" Garen snickered, unable to hold back his laughter, "If you just look at my body, it's almost an example of immortality, but…." He suddenly remembered the Cthulhu King from Totem World, and his smile faded away.
"In this world, there is no true immortality. Even if the body does not die, the soul will eventually decay. You have to understand this."
He also thought of his first encounter with Demon Phoenix. That powerful woman who claimed to be immortal, in the end, was sealed until her brain went strange. Maybe it was due to her soul.
