Xuan Chen's World-Breaking Record

Traditional Eastern Fantasy Novels

I'm looking for a very traditional Eastern fantasy novel. The setting was probably the Spring and Autumn or Warring States period. The heroine was a princess of the Zhou dynasty, and I can't remember the hero's name. They met while cultivating at an academy. The feudal states were powerful while the Zhou dynasty was in decline. She didn't confess her feelings because she was afraid of dragging him down.
