I Thought This Thing Could Defeat Demons

I'm thinking+Create equipment+Create power Lu Chen traveled through time and became a Chinese who inherited a blacksmith shop in a small American town. He originally just wanted to work hard to pay off his debts, until that night, a female ghost in white floated into his bedroom. Then he discovered - It seems that the iron you made yourself can really beat ghosts. The salt I sprinkle seems to really ward off evil spirits. I casually said "this thing can beat demons", as if... Can it really beat demons? Dean: "You call this a common blacksmith?" Sam: "I've looked through all the exorcism literature and can't find his theory." Constantine: "This does not conform to any principle of magic." Lucifer: "Why can a mortal with a hammer chase me and hit me?!" Lu Chen held the hammer and looked innocent: "I told you I'm just a blacksmith, but you don't believe me."
