Dai lap mat tam: Ling ling sing sing

During the Ming Dynasty, secret agent Ling Ling Ling (000) is tasked with probing a drug poisoning case 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 be featured in the book, attempt to seduce Ling, who, to placate them, transforms the manuscript into a collection of erotic tales. One day, a blind servant named Yuk Chu Nui (Jade Virgin) is put up for auction, and Ling discovers that the winning bidder will obtain the drug. Ling raises his bids in an effort to secure the evidence, but unexpectedly, someone else outbids him.
