It is said that Sai Mun Chui Sheut was able to defeat Ngor Mei Sect leader Dook Goo 1 Hok only because Fok Teen Ching had already drained Dook Goo's inner power before Sai Mun arrived to challenge Dook Goo. Had Dook Goo been at full strength, Sai Mun apparently would not have lasted thirty strokes against him.

What if a full-powered Dook Goo 1 Hok had to take on Sai Mun Chui Sheut and Yip Goo Sing simultaneously? Dook Goo apparently could handle either of them within thirty strokes, but can Dook Goo take both of them?
