When math problems are no longer symbols on paper, but life-threatening blades, the world in textbooks becomes a living hell. Uncle Wang's body was wiped out by the mauling of the chicken and rabbit in the same cage, Xiaohong was drowned by the cream of the fractional cake, and Xiaogang's body was cut into precise pieces by geometric shapes...
They are the "people in the problem" we are most familiar with, but they are backfired by mathematical rules in repeated calculations day after day. There is no protagonist, no redemption, just a series of massacres woven by formulas, numbers, and graphics. Open this bloody textbook and see how those characters who have given you headaches go to their doomed death in their own "exclusive question types".
The idea: to turn the hatred of mathematics and the fear of answering questions into a bloody massacre. Those problems that once gave students headaches and never-finished homework have become deadly weapons in the story. The death of the characters is the extreme projection of childhood "math anxiety", deconstructing the psychological fear under childhood learning pressure and completing a catharsis of negative emotions.
