Lin Chuan, a vocational school student majoring in auto repair, accidentally solves a “unsolvable problem” that has puzzled the math department for three years while fixing a library aunt’s computer. However, he’s accused of “cheating” by the school leaders, and even Su Wan, the cold math goddess he secretly likes, tells him, “Stop dreaming unrealistic dreams.” Until the invitation to the Global Math League arrives—Lin Chuan takes his three-year-old repair wrench (to unscrew the “encrypted” competition problem box of the organizing committee), crushes MIT’s top players all the way, and solves the “century-old unsolvable” final problem. On the final stage, he slaps the draft paper full of formulas in front of the doubters: “A vocational student’s math is the rigor from twisting three thousand screws.” And when he lifts the championship trophy, Su Wan hands him a note with red eyes—written in his problem-solving思路: “Your wrench unscrewed the ‘unsolvable’ in my heart.”
