A Plane-Hopping Shop Connects the Three Realms, and a Tiny Grocery Store Makes a Fortune

(New book: Transmigrated as a Villainous Guide, I’m Trapped in a Yandere Love Triangle. Please support it!) (Hoarding supplies + travel across worlds + multiple planes + System kept secret + no CP) Gu Yue had lost both her parents and inherited the family convenience store. Then, as if that weren't enough, she was diagnosed with a terminal illness. She thought all she could do was book her own cremation and wait to die. Who could have guessed that just before her death, she would suddenly be bound to a cross-dimensional marketplace System? To stay alive and make money, Gu Yue began a buying-and-selling journey across three thousand worlds. [A princess from a kingdom on the brink of collapse visits the store, leaves behind a jade thumb ring worth a million, and takes away hot-pot instant noodles...] [The First Emperor of Qin, before unifying the six kingdoms, visits the store, leaves behind a pile of bronzeware, and takes away seeds that cost one yuan a packet...] [A priest from a beastfolk tribe suffering from a lack of food and clothing visits the store, leaves behind strength-enhancing fruit, and takes away a truckload of padded coats and lighters...] Later, Gu Yue's business across the myriad worlds grew bigger and bigger. People from countless advanced planes came to trade with her, bringing immortal herbs, spirit stones, magic tomes, and interstellar miracle drugs in exchange for specialties from other worlds. Then things gradually took a fantastical turn... A substitute senior sister from a cultivation plane held a copy of Five Years of Magic, Three Years to Godhood from a magic plane and kicked her sect's scumbags straight to the crematorium. A good-for-nothing boy from a fantasy plane devoted himself to studying the hand-built mech technology of an interstellar plane and used science to defeat the whole world. A black mage from a magic plane, branded a heretic by the Church of Light, painstakingly cultivated spiritual roots and ascended to immortality in broad daylight. P.S. The events may not happen in the order listed. More planes are waiting to be unlocked...
