Jixia College decides to shake things up by inviting some of its most accomplished graduates back to campus as short-term stand-in instructors. Among them, Zhou Yu and Zhuge Liang Zhan turn the arrangement into a lighthearted contest between two teachers. Yao, the Star Team and the rest of the current students spend their days bumping into these returning alumni, and the result is plenty of everyday comedy. That changes when a mysterious crisis emerges, forcing alumni and students alike to drop their roles as teacher and pupil and stand together. Between chaotic mishaps and moments of real teamwork in battle, Jixia's ongoing legend picks up another chapter.
