After Dumping My Deadbeat Boyfriend, I Flee the Famine and Return to the Modern World to Stockpile Goods

【Farming + Fleeing Famine + Stockpiling Supplies + Pocket Dimension + Connected to the Modern World + Famine + Building Wealth + Everyday Family Life】 In her previous life, she gave everything for a scumbag, only to be tortured to death. In this life, she divorces him and returns to her family. But who could have guessed that her mother would scold her and favor the third branch of the family? She and her two older brothers are on the brink of despair. By chance, she activates a ring and gains a pocket dimension that opens onto a realm of immortals. From then on, she trades embroidery for instant noodles and hamburgers, thimbles for rice, flour, cooking oil, and other staples, and wild vegetables growing everywhere for fish and meat. The unremarkable things she owns bring her countless supplies. She sells items that can be tossed aside in the immortal realm for sky-high prices. Then famine strikes! She and her two brothers not only survive, but also build a fortune and enjoy a life of plenty. Her mother, who favored the third branch, and her third older brother weep in regret and beg to be taken in, while the scumbag regrets everything too late. She smiles faintly. “In this day and age, who still relies on men and relatives?” Behind me is an entire modern world supplying me with goods at a frenzied pace. There's no need to panic while fleeing famine. After she's reborn, her descendants in the modern world send her supplies. There is a male lead, but he appears much later!
