Ask for the title of a martial arts novel I read a long time ago

It seemed to be from 2005 (I remember that Prince Becomes a Frog was still broadcasting at that time)... He only remembered a few bits and pieces: it was about martial arts, and it was about Jianghu. The male protagonist had many wives. He practiced Yin and Yang cultivation or dual cultivation. One of his wives was the palace master of some palace. The disciples in the palace were all female, and they were all used to practice for the male protagonist. Sweat…He remembered that the ending was that the male lead and his wives had retired? He had a son, and his son came out to cause trouble in the martial world. There was a sign…There was a segment that he remembered very clearly. It was about the time when the male protagonist fell into a valley before he had any martial arts skills. Was it a cliff? Inside, he met a woman who was older than him. She @#¥ with him, taught him some cultivation techniques, and let him go. At that time, she wondered why the male lead had left just like that... So he remembered it quite clearly…There seemed to be a word "love" in the title of the book? Too much time had passed…Perhaps there was a deviation in his memory…Recently, I suddenly remembered…However, she could not think of everything…This feeling was too complicated…Help me think if you know...
