Lin Zhiyu, who was at the bottom of high school, grew up overnight after overhearing his father's humble call asking for money late at night. He started a silent march from the last place and used his self-created "knowledge tree" learning method to make a crazy counterattack. Mathematics teacher Jiang Yu discovered his talent and became his only confidant; Shen Moyan, the top grader in grade who once laughed at him, also became his strongest teammate. From being advised to go to a vocational school to winning the Olympiad national championship and being recommended to Tsinghua University, he spent one year rewriting his life. Returning to his alma mater many years later, he wrote on the blackboard in the classroom: dedicated to all souls who are unwilling to be mediocre.
