Traveling Through Chu and Han, I Survived Using Textbooks

As a sophomore in high school, I walked into the bloody battle between Chu and Han with a high school history textbook in my arms... Xiang Yu's 30,000 cavalry rushed towards me, and I only had two high school history books in my arms. It doesn't matter, I know who will lose and who will win in this battle better than Liu Bang and Xiang Yu.
