Dai lap mat tam: Ling ling sing sing

During the Ming Dynasty, secret agent Ling Ling Ling (000) is tasked with probing a case of drug poisoning linked to a performance-enhancing substance at the Ying Chun Kwok brothel. To infiltrate the establishment, Ling adopts the guise of the author of Yuk Po Tuen (Sex and Zen). The brothel’s prostitutes, eager to have their names featured in the book, attempt to seduce Ling, who, in an effort to placate them, transforms the book into a collection of risqué tales. Meanwhile, a blind servant named Yuk Chu Nui (Jade Virgin) is being evaluated, and Ling discovers that the purchaser will obtain the drug. He raises the bidding prices to secure the evidence, only to find himself outbid by an unexpected rival.
