What! My Grocery Shop Connects to the Past, and I Can Travel Between Worlds at Will

【Fake Heiress + Past-and-Present System + Getting Rich + Trading Supplies + Feel-Good】 Su Fei was the fake heiress in a true-and-fake heiress mix-up. She voluntarily left her wealthy adoptive parents’ home, but was lucky enough to bind herself to a trans-temporal grocery System, setting out on a journey to save the key figures of various small worlds. The peerlessly handsome prince: “Could she have fallen in love with me at first sight?” The adorable little koi princess: “Fairy Sister loves me best!” The iron-blooded God of War: “The deity actually likes weapons?” The imperial inspector: “Eating locusts? Could the deity have gone mad?” The Grand Princess: “Can this really stop the virus from spreading?” The little one: “You want to steal Sister from me? Come back when you’re as good as my artificial intelligence!” Su Fei helped a regent who was disguised as a woman and an empress become a couple, joined a matriarch in fighting a transmigrator, rescued a baby with mind-reading powers, helped a body-swapped emperor navigate palace intrigue, teamed up with a reborn legitimate daughter to save a general in a vegetative state, helped a princess win the favor of the Nine-Thousand-Year-Old, saved villains who had all turned evil, and brought civilization to the beastfolk... From then on, every small world had legends of a deity. Artificial rain? Walkie-talkies? A wave of eavesdropping devices? Even the ancients wore N95 masks... Meanwhile, the modern world suddenly filled with antiques from unknown dynasties. Don’t ask. How else can you explain why there are so many antique paintings worth hundreds of millions this year? They won’t lower their prices, and people are fighting to buy them. It’s just ridiculous! Su Fei shook her head in dismay. “Getting rich is too easy. There’s no challenge at all. Luckily, I can use money to upgrade and travel through all the small worlds. Otherwise, I’d really be worried. I can’t spend all this money...” The little one: “Sister, at least save some money so I can grow up. When I’m grown, I can...” Su Fei cut in: “Become me?” The little one: “Hmph!”
