While traveling through time in The Return of the Condor Heroes, Wang Jiuling unexpectedly learns the Innate Skill.

He killed so many villains in the martial arts world that they trembled in fear, and he even made a name for himself by chasing Li Mochou for thousands of miles.

Wang Jiuling also took Yang Guo as his disciple and, incidentally, brought Cheng Ying, Huang Yaoshi's last disciple, back to Quanzhen Sect.
From then on, Wang Jiuling became the pillar of Quanzhen, and with him around, Quanzhen became a leading figure in the martial arts world.

The five major sects besieged the Wudang Sect, but were utterly routed by Master Qingyang...
