This Is Really Not a Black Shop

"A handful of leeks, 10 ounces of soul, aren't you a black shop?" The alchemist looked at the middle-aged man in front of him, his eyes full of disbelief, and thought to himself, I am the store manager, I don't know whether this store is black or not. Rubbing his hands, he said with a smile: "Guest, my small business cannot stand what you say. Besides, guest, this is not a leek, this is an aphrodisiac!". The man looked at the wilted "Aphrodisiac Grass" in his hand and twitched the corner of his mouth. "Then I don't want it anymore, just retreat." "Okay, I'll charge you 1 ounce of soul for Leek's depreciation fee. Welcome to visit next time." Guest: "??? Didn't you say it's not leeks?"
