I had a dream of traveling through time when I was in junior high school. I wrote this because I read a lot of Verne's science fiction novels at that time. I was so obsessed with it that I imagined that I could go to a mysterious island and experience a big adventure. Another silly reason is that at that time, my friends were all reading "Looking for Qin", and I was so arrogant that I thought I could write something similar, so I came up with this article. Most of the characters in the article are good friends in junior high school, and they are included in the article to commemorate our pure friendship.
