Yu Pui Tsuen III (1996)

Ming Dynasty secret agent Ling Ling Ling (000) takes on a dangerous assignment to uncover a drug poisoning linked to a performance-enhancing substance at the Ying Chun Kwok brothel. To infiltrate, he adopts the persona of Yuk Po Tuen, the author of "Sex and Zen." As the brothel’s prostitutes vie for a place in his book, Ling reluctantly transforms it into a collection of risqué tales to appease them. During auditions, he discovers that a blind servant, Yuk Chu Nui (Jade Virgin), is tied to the drug deal, prompting him to raise bids for crucial evidence, only to find himself outbid by an unknown rival.
