Would you say that the stories of the three protagonists of DGSD, Kiu Fung, Hui Juk, and Deun Yu, actually intersected each other very little in the overall story? The first part of DGSD was dominated by Deun Yu, and it was a long time before Kiu Fung showed up. After Kiu Fung debuted, his story overlapped with Deun Yu's only briefly before Deun disappeared from the story for a long time. Deun Yu reemerged concurrently with Hui Juk's debut, but then Deun Yu disappeared again while Hui Juk's story unfolded. Everybody finally got together at the Heroes' Conference at Shaolin, and then they all went to Hsi Hsia Kingdom together for the Hsi Hsia princess' betrothal contest. After that, I think everybody went their separate ways again until the end when Hui Juk and Deun Yu tried to rescue Kiu Fung from Liao emperor Yeh Lut Hung Gei's troops.
All in all, that's very little time that the three protagonists' stories actually intersected each other.
