Zhang Wuji, like his father Zhang Cuishan, has developed an unattainable talent value in the martial arts column. At first, Zhang Sanfeng thought that Zhang Cuishan was the only disciple who could get all his true stories. Talent is high, and the chance on Zhang Wuji is really great. Zhang Wuji had Xie Xun, the Golden Lion King, as his teacher when he was very young, and he also learned the supreme practice of Jiuyang Zhen Jing when he was in exile, so he had such a good foundation.

In the Jianghu of Jin Yong's parents, Jiuyang Zhen Jing is an internal skill and the supreme skill to enhance the internal strength of practitioners. Therefore, when Zhang Wuji first went to the top of the light, he could hold the three palms of the extinct teacher even if he didn't learn other moves, and he could quickly return to his initial state after being injured. Therefore, Zhen Jing in Jiuyang is like a gain buff, which can provide unlimited internal force for Zhang Wuji and speed up Zhang Wuji's practice of other martial arts. Just like a good student with a particularly good foundation, if he goes to other classes, he will soon become familiar with and master the skills of this subject.

In the description of Jiuyang Shen Gong, there are several key words that need attention. All poisons don't invade king kong, and they don't rebound attacks? And then what? Easy to wash pulp? The first few words are particularly easy to understand, and they are all benefits brought by practicing the magic of Jiuyang. What does the last one mean? Simply put, it can regulate the yin and yang in the human body, so that practitioners can achieve the best state of cultivation. This is the key reason why Zhang Wuji practices martial arts quickly.

Zhang Sanfeng's strength is also due to his supreme internal strength. If Zhang Sanfeng can learn all the Nine Yang Scriptures, then Zhang Sanfeng must be the best person in the whole Jianghu. Internal strength is like the foundation of building a house. Without good internal skills as the foundation, even the best martial arts moves can't exert their greatest power. Just like other disciples in Sandu of Shaolin Temple, sitting still can exhaust the internal forces of Zhang Wuji and others. They are the most typical examples of internal forces. Later, although Song Qingshu had the internal strength to subdue the dragon's eighteen palms, Song Qingshu's internal strength was not strong, and he could not exert the greatest power to subdue the dragon's eighteen palms.
