我的学姐会魔法

This is a world where magic and science both exist. In this world, some people want powerful magic; some people pursue eternal truth. Blair, the protagonist, is a math teacher from a different world. Using both magic and science, he will soon achieve success in a way that no one has thought of before! A great scholar? The supreme mage? A lady-killer? I guess a few more titles won't hurt.
