My friend and I were stuck in a traffic jam in the desert and encountered a sandstorm. We traveled to ancient times and came with a golden finger system. It allowed me to open supermarkets, shopping malls, snack bars, clothing stores, shoe stores, and hat shops in ancient times. Oh my god, it was an illusion. It was an illusion, but it told me that I had many physical diseases, not only cancer, but also the inability to get pregnant. That would not work. I wanted to live. But after my supermarket opened, you told me that there was another time traveler in this world who was also opening a supermarket. I was confused.
