Start by Scaring Away the Evil God, and I Become a Guest in a Black Shop

I just traveled to another world, how come I was pulled into a crisis when I opened the store door? He was actually urged to kill the evil god by a talking little flame. "Mortal boy, take these three fairy cards and go and get rid of the evil god." "Me? Uh..." "Yes! The boy's urine that I have saved for more than 20 years is a top-grade and rare thing to ward off evil spirits~, and if I use this fairy card [Momentum Youth] to strengthen it, wouldn't it..." "Zizzizi————" The evil god was frightened away, but Shan Yue's achievements were wiped out by the shopkeeper Bai Yanerlang. Fortunately, by virtue of his status as an outsider, he became the first customer in this black shop to control his own fortune. "What!? This shady shop like you wants to share my work money. Twenty-eight cents, at most twenty-eight cents." "The store accounts for eight of them, that's right." "@#@%!!!"
