I want to invent the time machine most.

I want to see what life was like in ancient times. I want to see what those emperors and great men are like, and wonder what responsibilities they bear in the long river of history.

I am too curious about history, and there are too many unsolved mysteries in books.

I feel very excited to think about it, but I just think about it.

Maybe it's good to have a little mystery in history. After all, knowing everything makes everything unattractive.
