Personally, I think there are two mythical characters in Jin Yong's novels

Zhang Sanfeng and the nameless sweeping monk
Anyone who had seen the Eight Tribes of Heavenly Dragons would know the miraculous power of the sweeping monk.
Zhang Sanfeng's magic was believed to have seen the later stages of the Heaven Sword and Dragon Sabre, the Nine Yin and Nine Yang, and Zhang Sanfeng. Li Tianqi had lived for more than 140 years, and he was also a mythical figure in the later stages. In his generation, Zhang Wuji had only inherited a little of his martial arts, but he was able to defeat the two elders of the Chosen and become the leader of the Ming Cult.
It was hard to say who was the strongest among these two people. The last description of the sweeping monk was unfathomable and the Buddha's light shone brightly.
Zhang Sanfeng was a sage-like martial arts master
One of them was a representative of Buddhism, while the other was a representative of Taoism. They were the unprecedented martial arts peak in Chinese Buddhism and Taoism culture.
Does everyone agree with my point of view? The two of them were the strongest in martial arts, and Jin Yong had his own motives for using them to represent Taoism and Buddhism. There were three schools of thought in the history of China. Buddhism, Taoism, and Confucianism belonged to the literati. Buddhism and Taoism were not only a tradition of martial arts, but also a school of thought that was supreme and profound. They had already surpassed all secular things in the world. Later on, Zhang Sanfeng and the sweeping monk did it.

Answer 1

There are many mythical characters in Jin Yong's novels. The following are the two that I think are more famous:

The Couple of the Condor Heroes: Yang Guo and Xiao Longnu are the most famous couple in Jin Yong's novels. Their love story has been sung for thousands of years. Xiao Longnu was known as the fairy sister, while Yang Guo was known as the divine eagle hero. They all embodied mythical strength and charm.

2. The Eight Dragons: The Eight Dragons was one of Jin Yong's novels, which told the stories of Duan Yu, Xu Zhu, Murong Fu, and others. Duan Yu was known as Lord Duan, Xu Zhu was the son of the gods, Murong Fu was the swallow, Li San, and the others all embodied the characteristics of mythical characters, and their stories also had many mysterious and magical elements.
