My Pet Little Fox Is the Demon King [Management]

Sunny, straightforward young shopkeeper x scheming, lovestruck fox spirit. Sticking to a one-on-one romance. The plot features interplanar business and raising a deity, with cute pets, delicious food, and world-building. On the day she came of age, Lu Siwei received a birthday gift her mother had sent from far away: a small jade sphere that looked perfectly ordinary. Little did she know it was an interplanar trading System. Since there was nothing to do after the college entrance exams, Lu Siwei began her business venture, opening shops in different worlds. Her first stop: an apocalyptic world overrun by zombies! A supermarket in the apocalypse, bringing hope to the survivors... A magical general store in a supernatural world, stocked with absolutely everything... A chain of magical restaurants across a Western fantasy continent... And worlds of psychic powers, primitive civilizations, oceans, cultivation, and more... Lu Siwei, eyes shining: "Running a shop is so much fun! Being a swindler is so entertaining! My goal is to reach the boundless sea of stars!" Tang Qingyan, the bona fide swindler passing by, says: "Little Lu is so cute and innocent. She'd get cheated if I left her out there. I'd better take her home and keep her." Lu Siwei: "-_- Clearly, I'm the one keeping you!" If you find a little fox cub, of course you have to squeeze its paw pads, rub its tail, kiss its ears, and nuzzle its little belly! Little Shopkeeper Lu, looking blissful: "Mmm, fluffy little cubs are the cutest. My little fox is the best~" Little (Tang) Fox (Qing) Cub (Yan), struggling: "You brat, show some respect! Who are you calling your cub... Mm, just how many little fox spirits have you petted? You're awfully good at this..." The little fox gives up struggling: "Purr, that's just the right pressure. No wonder all those little fox spirits like her so much... Since she's taken such liberties with me, I can't let her go so easily. Once I've regained my true form, I'll tie her up and take her home..." The future Demon King: "Little Lu, sweetheart, don't go! Come home with me, like a good girl!" Shopkeeper Lu: "Just a little fox. Easy to handle. ^v^" Theme: Do business honestly; don't be a swindler
