Across 60 Billion Light-Years, I'm Still a Big Shot

In the solar system 5,000 years from now, humanity has reached a Type II civilization, with a presence in every corner of all eight planets. Yet it seems humanity is being kept inside the solar system. After 5,000 years of effort, humanity still cannot break through the solar system, which is less than one light-year across. Countless probes and spacecraft continuously venture beyond the system, but none can get past the Oort Cloud. After an experimental accident, the world's foremost physicist unexpectedly ends up 60 billion light-years away. There he finds a civilization unlike any other: a cultivation world, different from a technological civilization, yet full of legends resembling those of Earth. Is it coincidence, or is there some connection? Cultivation, advancement? That's impossible. Even after crossing 60 billion light-years, even in a world of cultivation, I represent 10,000 years of technological civilization from humanity in the solar system. I've crossed 60 billion light-years, and I'm still a big shot!
