Alberts's eyes widened.
What had he seen?
He had seen Arthur dousing the Wailing Banshee with two tubes of concentrated sulfuric acid!
Although Arthur was shouting 'Evil Spirit, purification,' what he poured out was definitely not Holy Water—after the end of the Holy Era, the formula for making Holy Water had long been lost, leaving only some finished Holy Water to be collected by people.
But after the entire Silver Age, even if some nobles still preserved Holy Water, how much of its power remained?
It was probably just slightly warm boiled water at best.
Seriously speaking, concentrated sulfuric acid was far more useful.
Moreover, what was more important was that the concentrated sulfuric acid actually worked.
Against the rumored Banshee who 'killed her husband and children, dedicated her body and soul to the 'Divine Spirits,' yet felt regret at the last moment and kept wailing,' the concentrated sulfuric acid actually proved effective!
