(General) Achieving Plane Milestones: Earth's Richest Man

Wang Beibei, an unmarried woman well past her prime, accidentally binds herself to a plane-trading device and transmigrates overnight to the summer seven years earlier, just after graduating from college. From then on, doted-on daughter Beibei ushers in a new era of trading! She brings her mother along, with her grandparents and father following behind, as well as a whole crowd of relatives, and sets out on the road to prosperity and happiness. Buy buildings, houses, cars, and handbags! Whatever she wants, she buys, making major contributions to GDP, ranking among the country's ten outstanding young people, and reaching the peak of life. Who needs to marry into a wealthy family? I'm the wealthy family. Who needs a man? I can make it on my own. No awful characters, no romance. The heroine gradually goes from a sweet, soft girl to a queen. To keep the trading device secret, she won't get married. There may be occasional flirtation, so feel free to hit X if that's not for you. There won't be a male lead who's even more overpowered than the heroine just to show off. I'm tired of those old formulas.
