Was it a tradition? Was the protagonist of this wuxia novel surnamed Long a typical setting?

The protagonist saves a little girl with purple eyes that have special abilities. The protagonist's father is disabled in both legs and knows martial arts. There are three women beside the protagonist. Their names are Green Dragon, Vermilion Bird and Black Tortoise. There are ten famous swords in the book. It seems that the protagonist used the Xuanyuan Sword in the end.
It's a modern novel that hasn't traveled through time, an urban martial arts novel.
