The story begins with a tragedy in a small village at the foot of Yunling Mountain in Qingzhou. Young Lin Feng survived the catastrophe and inherited the magical weapons and legacy of the former martial arts legend "Earth Sword" Zhao Qingtian. He was forced to leave the mountain village and step into the turbulent rivers and lakes.
He not only has to avoid the endless pursuit of the Nether Sect, but also needs to distinguish between friends and foes in trust and betrayal. From an ignorant boy, he went through hardships, met heroes, learned swords and practiced martial arts, and gradually uncovered the mystery of his life experience (his father was actually Lin Zhengfeng, the "Tiangang Sword" of the year), and gradually came into contact with the whole plot of the Nether Sect - its goal is far more than as simple as unifying the world.
At the same time, the truth about the decisive battle between Kunlun and the "Tiangang Earth Demon" eighteen years ago, the reason why the leader of the martial arts alliance is vacant, and the shadow of the court forces behind it will also be revealed one by one. Lin Feng needs to unite the remaining forces of the righteous way to find the lost inheritance of the "Tiangang Sword", and finally confront the powerful Nether Cult leader Huangfu Jue at the World Martial Arts Conference to determine the fate of the entire martial arts world.
