When he woke up, Bai Sheng found himself back in the classroom where he was a sophomore in high school. A familiar yet unfamiliar figure was standing on the podium loudly speaking a math problem. What happened? Is someone playing a prank? Pinch my leg. It doesn't hurt. Am I dreaming? There was a gasp from the side, "Brother, I didn't offend you, did I! Why are you pinching my legs!?" Dynasty! Isn't he traveling abroad? Am I really back in high school?
Purpose: Dream come true
