Trading Trip to Another World

In 2098, Lin Wei, a 25-year-old girl who had been struggling in the steel jungle for five years, finally used all her savings in exchange for a RV of her own. She thought this was just the beginning of "having a family", but the moment she opened the car door, she was hit by a "different world transaction system" that appeared out of thin air - it turned out that buying a RV also came with travel benefits. From then on, every once in a while, Lin Wei and her RV will be thrown into a strange and bizarre world: it may be the medieval continent where magic and dragons coexist, it may be the punk world where machinery and steam roar, or it may be the future star field where technology crushes the earth. She brought lighters, antibiotics, and solar panels from the earth in exchange for magic crystals, mechanical cores, and healing pollen from another world; she used modern knowledge to help the indigenous people solve their famine, and used resources from another world to improve the lives of relatives on the earth. The RV is her mobile fortress, the system is her transaction bridge, and she herself has transformed from an ordinary girl into a "cross-border businessman" traveling through the multiverse through time and space. But as the transaction deepens, she gradually discovers that the connections between these worlds are far closer than imagined, and her appearance may have been written in an ancient prophecy...
