Indeed, it may seem strange that a piece of ore with the power to disrupt fantasy has emerged in a world where magic and Battle Qi are commonplace. However, regardless of how strange the existence of that piece of ore may seem, its great power would not be weakened for any reason at that time.
A Phantom Killer, even in a world where magic and technology coexist, can be referred to as the strongest glitch. Now, in a world composed entirely of super-real elements, one could easily imagine how powerful that piece of ore, akin to the Phantom Killer in abilities, could be.
To be blunt, if that piece of ore could be melted and fashioned into a hilt weapon, it could possibly be transformed into a Demonic Slaying Weapon. Although it's impossible for it to have the same amount of damage as a Phantom Killer which could annihilate anyone it comes into contact with, in this world, it can undeniably unleash divine artifact-level damage.
