It's Hard to Be a Passerby

It's like this, I'm an ordinary person. Unsurprisingly ordinary people. On this day, a system came to me. It said it could take me through different worlds, and all I needed to do was complete a simple task - to be a passerby in each world. I think it's too easy. I am just a passerby in my world, can I still become a boss in other worlds? Yes. ————— Purpose: Live every day seriously
