Questions about a Wuxia novel

When he was young, he had read a martial arts novel. He could not remember the title of the novel, nor could he remember the names of the characters in it. He only remembered the general plot. The gist of it was that there was a couple. The wife had contracted a strange illness and could not be cured. She could only become a monk to save her life, so she became a monk and left her daughter and husband to rely on each other. For some reason, the husband did not understand and never allowed his wife and daughter to meet again. Her husband had learned martial arts after saving his daughter once, and he had become famous ever since. After that, it was all about when her daughter grew up. Her father was seriously ill. After her mother found out, she deliberately leaked the matter to the martial arts world, attracting many people to look for her husband's martial arts secret manual to vent their years of dissatisfaction. Then, her husband died. A young man saved her daughter, and her daughter went on a journey with that young man. Many things happened after that. Her daughter met up with the young man and parted ways. As a mother, she had not been able to recognize her daughter for a long time. However, in the days when the young man was not by her daughter's side, she had always tried her best to protect her. That was probably all he remembered about the plot. There were still many things that he could not remember. The story is mainly about the daughter's generation. The books seem to have the basics of upper, lower, middle, and lower. I only read the first book. It's been a long time, but I can't remember clearly. Now that he thought about it, he really wanted to read this book again, but he couldn't remember anything else. There seemed to be a little bit of fantasy in it. The girl would sometimes emit a purple light, but only a few people could see it. There was also the ancient bone hairpin on her head, which could prevent danger. When the food she ate was poisonous, the hairpin would sting her head and remind her not to eat it. Can anyone tell me what book this is and who the author is? Thank you! It's about to expire. Please help me, Wulin hero! What kind of book was it?
