If I had known that one day I would travel through time, I would never have studied archeology, but now I can only wait to be tested by others.
If I had known that archeology graduate students were just strong laborers digging up dead people for free, I would have been willing to build the Great Wall... Well, I really built the Great Wall in the Qin Dynasty now.
Why do other people travel to the Tang, Song, Yuan, Ming and Qing dynasties? After enriching material wealth, why should I want the Warring States period when I didn't even have a choice of vegetables?
You said I would just go to the Warring States Period, but why am I not even a member of the Qin State?
God, do you think I can overturn history, let Qin Shihuang die early, and enter a feminist society in the future!
