I Just Went to Take a Dump, So Why Am I in the Great Song Dynasty?

A vocational college student studying medical technology is just taking a dump, making a few sarcastic remarks, then heading back to flop onto the bed. He opens his eyes, closes them, and, hey, he's transmigrated? Does that even make sense? And they've sent me all the way to the Song dynasty!

To make matters worse, there are quite a few “fellow countrymen” here?

And what about everything going on over in Europe?
