Reborn as Gao Lian, I Wrote the Proof as a System for Cultivating Immortality

Xu Guizhou, a thirty-six-year-old frustrated mathematician, traveled back to the high school mathematics competition school team selection site on a night when a critical gap in his paper was pointed out. He could not directly copy the answers and could only see the logical cracks in his proof. So he went back to the competition road from school team selection, high school league, provincial team, winter camp, and national training team to prove all the "almost" in his previous life.
