Academic genius: Arcane Invasion of America

Li Ang transmigrated to a magical world resembling medieval Europe, yet imbued with magic. He discovered that learning magic was incredibly difficult. Mental talent, spellcasting materials, and being wanted by the church—all were insurmountable obstacles in his path. Good news: Li Ang awakened a system. Bad news: the system panel lacked a wizard profession bar; instead, it displayed levels in mathematics, physics, chemistry, and biology. So, this was a genius system? In a magical world where survival was precarious, what use was it?! Until Li Ang discovered that in the magical world, knowledge was power, scientific theories were magical models, and he could even use the system to travel to 60s America. Okay, Li Ang admitted he'd raised his voice a bit. ...Many years later. Li Ang sparked a magical world renaissance. He conducted experiments, reasoned, disseminated his research findings through journals, and became a legendary arcanist. And America welcomed its only extraordinary being.
