The couple stared at the phone screen, listening intently to what Mr. Spirit Crows had to say next.
"In the Supernatural Domain, any attempt to take shortcuts cannot avoid the cost. Forcibly advancing to a Warrior through blood sacrifice is no exception.
"Most people might not know that, in essence, a blood sacrifice is using a Super Converter to transform the life and soul power of the offering into other forms of power.
"And the 'Super Converter' I'm talking about is actually something of an extremely high level.
"Each blood sacrifice is equivalent to borrowing the power of the Super Converter. Do you think such power would let you use it for free?
"With an ordinary mortal's insignificant body, to wield an unimaginably powerful force—how could there not be a price to pay?"
The couple nodded repeatedly as they listened.
Erin showed a thoughtful expression: "Makes a lot of sense."
