Fanchen Asked

Is there really time travel in the world? What would you do if you traveled through time? How many geniuses are there in the world of immortality? Do you think you will stand out? I had a particularly long dream, and I can barely remember the memory of the dream, so I wanted to record it in the form of a novel. Just take it as a joke, don't take it seriously, the real world is really, really good. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
