Told in the first person, this story follows Lin Huai, a street punk abandoned as a child who makes his living in underground boxing rings but secretly has a photographic memory for mathematics. When he helps the heroine, Su Wanzhao, solve a data problem at her company, a prestigious university professor discovers him, forcing him to reveal his talent and enter academia. Along the way, a jealous top student, a boxing rival turned villain, and an obsessive suitor take turns provoking him. Lin Huai uses a street punk’s unorthodox tricks and mathematical logic to face-slap them all: he wins boxing matches with game theory, exposes research scams with group theory, and designs business strategies with topology. With the heroine’s healing support, he grows from “street trash” into the “wild king of global mathematics,” ultimately reaching the twin pinnacles of becoming the boxing champion and a legend in academia, while finding love with Su Wanzhao.
