Novel & Cerita Wuxia Novelist

Gold-tier fighters who had survived things that should have killed them turned around and walked away from her without explaining why. She had destroyed three kingdoms. The novel stated this as historical fact, briefly, in a section of worldbuilding that the author clearly found more interesting than the hero's romantic subplot but had buried in Chapter 74 anyway. Three kingdoms, across what the novel implied was a very long time, for reasons that were never specified.
