Lin Yue was originally just an out-and-out otaku in the 21st century. On the day of his 23rd birthday, he found that he had jumped on the bandwagon and traveled through time.
However, what if someone else has traveled through time to either ancient times or modern times, and you have traveled to modern times? Or I wore it abroad and became a pink and tender little kid.
But he is still a loser in history. Not to mention foreign history, he has never even understood Chinese history...
