In the early Qing Dynasty, Emperor Kangxi was still young, treacherous officials controlled the government, and the people were living in misery. "Heaven and Earth Society" was a civil organization that overthrew the Qing Dynasty. Chen Jinnan (played by Liu Songren), the leader of the "Heaven and Earth Society", was fortunately rescued by Wei Xiaobao (played by Stephen Chow) in an operation. Xiaobao joined the Heaven and Earth Society and was sent to the palace as an undercover agent to steal the 42-chapter Sutra containing the secrets of the Qing Dynasty. The clever and clever Xiaobao soon became the emperor's confidant and became a high-ranking official. Xiaobao was caught in a dilemma. He had to carry out the mission but became good friends with the emperor. Just when Xiaobao wanted to escape, his master Chen Jinnan also found him and sent someone to monitor him back to the palace. Soon, Xiaobao was hunted down by the Aobai Alliance and the fake queen mother, and fought against the people of the Heaven and Earth Society.
