His objective was to find a way to achieve immortality.
That person started studying the nature of the human body and its connection to magical magical energy.
He soon realized that in order to live longer he needed to increase his life force which coincidentally magic energy also nourished the source of our long life.
The higher the amount of magic energy a person can attain and control, the longer they live."
Elysia was intrigued by the information she had just received. She didn't think that even the people in Noah's world would also be obsessed with eternal life.
"So did he make this stone to attain immortality?! Was he successful?"
Hearing Elysia's excited voice, Noah could not help but chuckle.
"No he failed. That person died miserably in the war..."
"....."
His words dumbfounded the woman not realizing what was his point of telling this story if he was not the one who created this stone.
