Emperor Kangxi (played by Kent Tong) is seriously ill. The imperial teacher learns from his practice that his destined empress has not yet appeared, causing his body to feel unwell. The only solution is to order someone to go to the future to find the true Queen Phoenix to match Kangxi so that the emperor can be saved. This task is given to Wei Xiaobao (played by Tony Leung Chiu-wai) to carry out. Xiaobao then takes the high-tech crystallization of the Rakshasa Kingdom - the invincible Hun Tian Wheel that travels through ancient and modern times, and accidentally arrives in Hong Kong in 1993, and meets a street kid named Yachao (played by Dicky Cheung), and the two become friends. On the other hand, Xiaobao meets elementary school teacher Xia Nu and gradually falls in love with her. However, at this time, seven wives headed by Princess Jianning (played by Ip Man-shing) come to the modern world to look for their husbands, which causes a series of interesting events. In addition, Wu Sangui sends his men to hunt Xiaobao to stop him from looking for the queen. Faced with various problems, how should Xiaobao make a decision?
