Regarding Yiqu's question, Su Zi gave a unified evaluation: "When I was in elementary school, I felt that I was a pure and innocent piece of white paper, and the facts have proven this. Although I was affected by many factors in junior high school, overall I still feel that I am very pure, but the color has changed a little, probably because it has been oxidized after being left aside for too long. Now after listening to my brother's remarks, I realized that compared to you and me, I am just a cub among the wolves."
Yiqu, on the other hand, frowned and looked disappointed, saying, "Brother! Please don't use your degrading thinking to think about these extremely valuable research questions of mine, okay?"
