After helping Lin Ruoxi swap out her desk, Xue Rui walked her home as usual.
On the way, Xue Rui casually asked, "What have you studied in math? Calculus?"
His advanced math grade in college had depended entirely on participation points, and he only barely passed because the professor took pity on him.
So, Xue Rui genuinely admired anyone who could pass on their own merit.
In his eyes, anyone who would willingly study advanced math could already be called a genius.
"Um... Principles of Mathematical Analysis, Algebra, Analytic Geometry, Topology..."
Lin Ruoxi figured that if she confessed honestly now, she might get yelled at less later, so she listed all the books she had studied.
Xue Rui stopped in his tracks. Those were all university-level courses.
In fact, there were many he had never even heard of—ones that non-math majors would likely never encounter.
"Do you like math?" Xue Rui asked. He thought he might have just discovered a mathematical genius.
