In Jin Yong's novels, cultivating internal energy was a very important way of cultivation that could help the characters improve their strength and abilities. If a person cultivated multiple internal arts, their strength would be greatly improved. For example, Wang Yuyan, the leader of the Carefree Sect, had practiced many internal skills in the Eight Heavenly Dragons, including the Tianshan Plum Splitting Hand, the Six Sun Palm, the Jade Flute Sword Technique, and so on. These internal arts could work together to give Wang Yuyan a very strong fighting strength in battle. In addition, in the Legend of the Condor Heroes, Guo Jing also practiced a variety of internal skills, including the internal skills of the Seven Monsters of Jiangnan, Huang Rong's internal strength, and Hong Qigong's martial arts. These internal arts complemented each other, allowing Guo Jing's martial arts to improve greatly. Therefore, cultivating a variety of internal arts can greatly improve the strength of the character and help the character have more confidence and advantage in battle.
