I Am the Only One in the World Who Has Not Traveled Through Time

Time travel gives people a rare but old-fashioned feeling. However, one day, the whole world traveled through time. Under the appearance of a human being, he may be a demon, a dragon, an elf, or he may still be a human. But I didn't travel through time! And my existence seems to have turned into a bug. Hey hey hey, I'm the only one who hasn't traveled through time, why do I feel like I'm in a different world?
