Amberser crushed several Pseudo-Souls, their pure Soul energy seeping into the hourglass, replenishing the power of the slumbering Arthur Laine.
The essence of a Heroic Spirit is a Soul in a special state; the difficulty in recovering power lies in the scarcity of soul energy.
Heroic Spirits lack the ability to restore themselves by devouring Souls, and only Amberser could manipulate such power to heal Arthur Laine.
James Watson watched as Amberser turned a pile of materials into blank souls and couldn't help saying, "Is that how the Life Caskets came into being? I was doubting that you could possibly slaughter hundreds of thousands without any news leaking out."
Amberser cursed, "Massacre hundreds of thousands? Are you insane? If I had killed that many, Alchemy City would have done me in long ago. Without a population, who would serve as laborers for the Alchemists?"
This was one of the reasons why James Watson was willing to issue a pardon for Amberser.
