The protagonist of " Blacksmith from Grave Robbing " was a blacksmith who often had to face all kinds of dangerous situations and mysterious events. When he encountered something unclean, he would smash it with a hammer. In " Picking up a Thousand-Year Zombie as a Pet," the protagonist ran into a Thousand-Year Zombie and a human-skinned monster on his way to escape.
