Reborn with a Notebook of Mistakes: I Ascend to Immortality Through Calculus

I was reborn in a parallel city where, on the surface, students compete fiercely for college admission, while beneath that, technology and cultivation are intertwined. Top students comprehend the Dao through brain-computer interfaces, and the more papers they publish, the stronger their true qi becomes. In my previous life, I was expelled from school. Now, I have awakened a golden finger called the "Wrong Answer Notebook": for every question I get wrong, I gain a flash of insight that lets me rewrite reality. While others painstakingly cultivate their techniques, I use calculus to break through realms, wield formulas as incantations, and draw talisman arrays on scratch paper. Back in my final year of high school, I will climb the ladder of knowledge, outcompete everyone, and become the first ruthless genius to ascend through mathematics.
