She grew up in the Xiao Clan and was Xiao Yan's childhood sweetheart. Beyond that connection, she's known as an exceptionally talented fighter in her own right. Her background remains largely shrouded in mystery, though what's known is significant: she's the primary heir to the Gu Clan and carries something rare within her bloodline—pure Dou Di blood, something the clan hasn't seen in over a thousand years. Fans often point to this bloodline as central to understanding both her strength and her importance to the overall story.
