Luk Siu Fung and Sai Mun Chui Sheut's friendship seemed to peak during the events of THE DUEL. In the days before Sai Mun Chui Sheut dueled Yip Goo Sing, the extent of his friendship with Luk Siu Fung was well-explored and it was clear that the two men had a great amount of trust and respect for one another.
But was it all downhill from there?
Sai Mun Chui Sheut showed up very briefly at the end of the next LUK SIU FUNG story, THE SILVER HOOK CASINO saga. Sai Mun Chui Sheut showed up briefly at the very end of that story to help Luk Siu Fung against the Sui Hon Three Friends, as Luk was counting on. Sai Mun Chui Sheut left with a cryptic comment, however, that now he owed Luk Siu Fung nothing (or something to that effect). Sai Mun seemed colder towards Luk Siu Fung than he had in THE DUEL or the GOLDEN ROC KINGDOM'S TREASURE saga.
In the story following SILVER HOOK CASINO, the HAUNTED VILLA, Luk Siu Fung and Sai Mun Chui Sheut were openly opposing one another...although it was a simulated conflict designed to fool the Wooden Taoist/Old Sabre Tyrant into exposing his plot. The conflict might have been simulated, but Luk Siu Fung and Sai Mun Chui Sheut, especially, treated it as if it were real. Did their friendship ever fully recover from this incident?
