Zhei Jiushi Xiuxian?

A former zither cultivation prodigy was destroyed by lightning during a tribulation and remained lifeless at the base of a cliff for three centuries. During this time, he waited for a successor but only saw sword cultivators. After three hundred years with no one from his cultivation path, a long-haired man fell from the sky while being pursued. The prodigy was overjoyed, believing the newcomer to be a zither cultivator due to his aura and appearance. However, he was soon informed that the man was actually a sword cultivator.
