Siheyuan: I Traveled Through Time and Became the Only Top Student in the Whole School

He died suddenly while working overtime and traveled back to the courtyard in 1960, becoming Yan Jiecheng, the eldest son of the third uncle Yan Bugui. I eat batter with pickles for breakfast, wear coarse clothes and live in an old house. There are only a few subjects in the class, including mathematics, chemistry, and physics, which are all basic, and I already know Russian. These days, exams are like fun to me. I have to be a top student first to calm down my worries.
