The Witcher: Start with a Revolver

The curse of the Calamity Night permeates the border land, and werewolves, vampires and aberrant monsters hunt mortals in the wilderness. When Kane was about to die, he accidentally awakened the demon-hunting weapon arsenal system, which can be exchanged for silver-plated weapons, mithril bullets, and demon-hunting firearms. However, the system only provides weapons and will not grant a supernatural body. He was still a mortal man of flesh and blood, and his wounds could prove fatal. He traveled around to accept bounties and survived in the cracks between monsters, nobles and the church. As the hunt continued, he discovered that the demon hunting system seemed to be entangled with the curse of this land.
