Shen Gong of Jiuyang is a peerless knowledge spread by Zhang Sanfeng, the founder of Wudang, according to Zhen Jing of Jiuyang. When you practice this skill, you can produce purple gas, which can spread to the inside and outside at will. You can be invulnerable, fire and water are invulnerable, poisonous gas is not born, and you will disappear, and the indestructible body of King Kong will follow.

Edit this paragraph, version history

In the original version, all the nine yin and nine yang were created by Buddhism. In the old edition of "Eternal Dragon Slayer" (formerly known as "Heavenly Sword and Dragon Sword"), the name is really rustic! Just like a third-rate martial arts novel. Friends who don't know thought it was fake at first glance, hehe. There is an obvious exposition in it: Jiuyin Zhen Jing emphasizes external work, Jiuyang Shen Gong emphasizes internal work.

Later, it is estimated that Jin Yong read a lot of Taoist classics during that time, and he was more inclined to China's inherent culture in cultural identity, so his martial arts origin turned to Taoism. Therefore, when he changed to "The Dragon Slayer", he made great efforts to write that "the martial arts of the western regions are more profound than that of China, after all, the knowledge of the Central Plains is more profound."

Probably because of this tendency, or because some of his friends' opinions influenced him, he spent a whole chapter in The Condor Heroes to write the source of Jiuyin Zhenjing, and transferred the intellectual property of this scripture from Dharma to Huang Shang.

This tendency is even more obvious in the revised edition of "Eternal Dragon Slayer", which obviously comes from Shaolin's "Jiuyang Shen Gong", and it must be added with Taoist origin.
