Four hundred years of troubled times, martial arts are rampant, and the world is like hell. Wei Xuan, a grassroots martial artist whose family was wiped out, set foot on Qingxi Mountain where the legendary Guiguzi secret book is located, in order to avenge a bloody sea of blood and to establish a chivalrous group that supports justice. On the way, he encountered the attention of three Taoist priests from Wudang, Huashan and Zhongnanshan, and was involved in a shocking conspiracy against the entire martial arts world.
The mysterious organization "Duijun" used Guiguzi's secret book as bait and set a trap to hunt down the martial arts people. Three Taoist priests died in battle, and Wei Xuan fell into the abyss. In a desperate situation, he accidentally broke into the thousand-year-old cave left by Guiguzi, and used his broken body to challenge the method of "unity of heaven and earth"-forcibly pouring the energy of nature into the human body.
After narrowly escaping death, Wei Xuan was reborn and gained enough power to overturn the world. At the same time, Tao Jun, the successor of Tianjian Sect, and Yaying, the eldest daughter of the Nangong family, followed and found that someone had taken away the power. Tao Jun knew very well that if he were not the inheritor of the Heavenly Sword, those with this power would become the biggest threat in the world.
