Holding a pen and copying the answers in Shen Yao's homework book, Lin Xiu's vision gradually blurred. Suddenly, a burst of fog came, and Lin Xiu's eyelids closed involuntarily. When she opened her eyes again, Lin Xiu was horrified to find that Shen Yao's notes were being twisted rapidly. What appeared next was bloody handwriting: "Xu You, Xu You. Xu You! Xu You..." The words covered the entire page. A gust of cold wind blew towards her face, making Lin Xiu feel chilled all over.
