The founder of Wudang, Zhang Sanfeng, and his senior brother Dong Tianbao (the commander of the Jinyi Guards) use their "Tao Heart" and "Power Sword" to protect the people in troubled times. Its successor, Zhang Wuji, was trapped in the netherworld for fifty years in order to seal the rift of the Nine Netherworld. He returned from a serious injury during the Hongzhi period of the Ming Dynasty and found that the Nine Provinces Dragon Vein was being quietly eroded by the "Net of the Nine Netherworld", and that the mastermind behind the scenes was pointing directly into the depths of the Ming Dynasty royal family.
Three generations of true martial arts heirs, a battle of protection that runs through ancient and modern times - martial arts were used to suppress the netherworld in ancient times, while martial arts are used to defeat illusions in modern times. When the Kunlun earth is shaking and the ancient heroic souls are about to return, Zhenwu Chongguang's prophecy is ushering in the final chapter.
