One of the beneficial side effects of practicing the Bak Ming Sun Gung and other Siu Yiu Sect martial arts is increased longevity. Indeed, Mo Ngai Tze and Lee Chou Sui looked middle aged although each of them was actually very old, and Teen San Tung Lo looked like a teenager although she was actually an old woman.
Hui Juk eventually gained the inner power of all three and learned their skills. At the time, he was in his mid-twenties. Did he continue to age normally after that, or did his aging slow down dramatically as theirs did? If his aging was indeed arrested, is it possible that he was still alive at the time of the Mt. Hua Sword Tournament decades later? Could he have overlapped at least a few years with Central Divinity Wong Chung Yeung and the Greats? Hui Juk almost certainly lived through the time of Wong Seung and Dook Goo Kau Bai.
