Crossing over with a hand-waving dance, appointed as the Grand Preceptor. Modern stage practitioner Su Yaoyao accidentally crosses over to the Dayao Dynasty. Encountering a severe drought, at a critical moment she relies on her hand-waving dance to bring heavy rain, and is conferred as the Zhaohua Grand Preceptor. Veteran court officials and imperial concubines repeatedly make things difficult and frame her, but she resolves each one with modern knowledge, managing the locust plague, building embankments, and opening schools. Single-mindedly bringing welfare to the common people, she also gains the emperor's complete trust, and the two join hands to wipe out the wicked officials in the court and pacify the realm.
