In Gu Long's world, there are a few earth-shattering jiang hu battles that have become engraved into people's heart, such that generations later still remember these battles. For example, Ximen Chuixue vs Master of White Cloud City Ye Gucheng, Little Li Flying Dagger vs Shangguan Jinhong, 3rd Young Master Xie Xiaofeng vs Yan 13, and Chu Liuxiang vs Water Matriarch Yin Ji.
Are there such legendary fight scenes in Jin Yong universe that future generations have commit to memory? The only qualified ones I can think of are Huang Shang's duel with Ming Cult, and the first Huashan Tournament.
