Dugu Qiubai, the Sword Demon

Whenever I think of Mr. Jin Yong's works, one character always comes to mind: Dugu Qiubai. I've read many novels that mention him, but none match the image I have in mind. Unfortunately, I don't know enough to write well. I once tried putting pen to paper, but the effort came to nothing. After all these years, I want to continue the story, though I can only do my best.
