First of all, Quanzhen religion was founded by Wang Zhongyang. According to the teaching in The Condor Heroes, before discussing Huashan's sword, Wang Zhongyang swore gloomily in the ancient tomb that he would never leave the grave. One of his opponents challenged him, so Wang Zhongyang walked out of the grave and saw that the oath had been broken. Actually, the opponent is Lin Chaoying, Tomb Raider's mother-in-law. Wang Zhongyang knew that Lin Chaoying was trying to cheer herself up and was very grateful to her. Even when he died in Lin Chaoying, he secretly went back to the tomb to mourn Lin Chaoying, but he also left it on the tomb: Chongyang was not weaker than others all his life. And even if he lost the mausoleum to Lin Chaoying, he promised to become a monk in Zhong Nanshan, and he didn't stay with him all his life. Finally, he told Lin Chaoying to put down the broken dragon stone. There is a secret passage to leave the grave. It can be seen that Quanzhen religion in Zhong Nanshan was established to the death because Wang Zhongyang, one of the best religions in the world, lost to Lin Chaoying. More than a hundred years earlier than Wudang.
Wudang can be said to have originated from Shaolin. When Zhang Junbao was a child, Quanzhen religion was no longer the largest religion, and the seven disciples of Wang Zhongyang were really not so good. At this point, Quanzhen religion was dying. After Xiangyang city was broken, it basically ceased to exist.
Zhang Sanfeng, that is, Zhang Junbao, and Guo Xiang are people of the same era, which is the origin of Wudang and Emei in "Eternal Dragon Slayer". Zhang Junbao is a disciple of Shaolin master Jue Yuan. Master Jue Yuan once taught the Shurangama Sutra to Zhang Sanfeng, Guo Xiang and others. After Guo Xiang returned, he achieved the feat of Emei Jiuyang. After leaving Shaolin, Zhang Sanfeng traveled all over the country and stopped at Wudang Mountain. Because of his love for this mountain, he founded a sect here for Wu Tangmen. At this time, Quanzhen religion had already declined to nothing. It can be said that the two have nothing to do with inheritance.
If not related by blood, Zhang Sanfeng himself has a close friendship with Guo Xiang, and Guo Xiang is the son of Guo Jing. When Guo Jing was young, he received Ma Yu's on-demand program, and later claimed to be a disciple of Chongyang Palace. His sworn brother, the old urchin, was the younger brother of Quanzhen founder Wang Zhongyang. That's all.
