I'm looking for a martial arts novel!

As he had watched it a few years ago and hadn't finished watching it, he didn't have a deep impression of it. He couldn't even remember the names of the characters in it!
The plot of the story was like this: A group of bandits robbed a village. The entire village was killed. There was a little girl in the village. Her father was killed by the bandits, and her mother was killed. Then, the bandits took a fancy to the little girl. At the critical moment, a middle-aged man in his forties saved her and killed all the bandits. He deliberately let the bandit leader go so that the little girl had a reason to live. Then, she would grow up and take revenge!
This 40-year-old man was actually in disguise. He was only in his 20s. His parents had died a long time ago. His father seemed to be a divine doctor. His grandmother was the leader of some sect. His mother looked very similar to his grandmother. His grandmother still looked like a person in her 20s. It was a story from the end of the Yuan Dynasty. The descendants of his grandmother's sect and the previous dynasty's royal family rebelled under the banner of opposing the Yuan Dynasty and restoring the Song Dynasty. In fact, they wanted to be the emperor themselves. His grandmother and that previous dynasty's prince had their own ulterior motives. Grandpa Wang had a younger sister. In order to control the main character's grandmother, Wang Ye asked his younger sister to seduce the main character. Because the main character only had one family member, and his grandmother only had one family member. Wang Ye's surname was Zhao (Of course, the royal family of the Song Dynasty had the surname Zhao. Fortunately, I still remember a character with the surname Zhao!) This woman went to approach the protagonist and said that she was sent by his grandmother to assist him! Then, their relationship slowly became better and better. In the end, they became a couple. Then, the woman seemed to have been scratched on the face during the battle with Yuan Jun. After that, the protagonist cured her. That was all she remembered!
It was the novel mentioned in the 5th story of "Playing Sword, Composing Song, Playing Bitter Voice"!

Answer 1

There were many martial arts novels that could be referred to as the following famous one:
Eight Demigods.

This novel told the story of the Southern Song Dynasty when the various sects fought for the Heavenly Dragon Saber, the Nine Yang Scripture, and the Tianshan Plum Breaker. The main character was a handsome young man named Duan Yu. He was talented in martial arts, but he had also experienced many twists and turns. There were many wonderful descriptions in the novel, including the love and hate of the martial arts practitioners, conspiracies and plots, and bizarre twists and turns of the story line, which were very popular among readers.
