This is really a sad story. He actually traveled through time. Although this time travel, for a scholar like him who wanders in the ocean of knowledge and has glasses as thick as the British dictionary, it is interpreted as the result of an accidental encounter in different parallel time and space. If he has the chance, he does not mind being foreign. It's coming, but the time is really wrong. Parentheses, wouldn't it be too cruel to do this to a child who has been studying hard for a whole year, during which interpersonal communication was limited to the aunties in the cafeteria, and who is about to take the postgraduate entrance examination? ? But where are the brackets, instantaneous movement, time standing still, etc. The top student said it is unscientific, and what's wrong with him? He is an earthling, not a small animal on your planet. It's really sad to be "dehumanized" like this~~
