The world of wuxia fiction is far removed in both time and character from the modern world in which we live today. Because most of the wuxia fiction popular today was written by authors who live or lived in modern times, however, inevitably, some anachronistically modern ideas leak into the wuxia fiction that they write. What examples can you name of anachronistically modern ideas showing up in wuxia fiction? This can cover technology, social attitudes, or verbal expressions...moments when you went, "Huh. I didn't know people had/were aware of such things in ancient times!"
