Su Man: If time travel is compared to a career or a job, I would be a loser. Because I simply can't handle the relationship between the familiar memories in my mind and the facts in front of me. At that time, I almost collapsed. At that time, I even started to think about what is real and false, and the relationship between dreams and reality... I felt like I was walking alone in the fog. I had a vague intuition that I would be killed by my own brain and thoughts! I disappeared from the world inexplicably, and no one remembers me... Heh, maybe I don't even know who I am, Su Man - it's just a fantasy...
