Another scenario.
Xiao Feng died around age 30. But imagine he lived on as a martial artist. This is him at age 50. You get to imagine at what level he should be by now.
Dugu Qiubai @ age 50 - why pick this age? It is said that after age 40 is when he moved to use Wooden Sword and other non-traditional objects such as rocks and bamboo sticks, and that he gradually progressed towards the stage of Overcoming a Sword Without a Sword. It was not mentioned exactly when he reached the no-sword stage, but from his history, it seems he reached a new level every 10 years, so let's assume he reached no-sword stage at age 50.
