With the growth of Ye Jingtang, a transmigrator, as its main thread, the work tells the story of how he inherits the bloodline of the last Heavenly Lang King, dominates the martial arts world with his self-created martial art The Nine Phoenixes Facing the Sun Skill, and gets involved in the disputes between the imperial court and the martial arts world together with female characters such as Luo Ning (wife of the leader of the Pingtian Sect), Pei Xiangjun (head of the Red Flower Pavilion), and the Female Emperor of the Great Wei Dynasty. The worldview revolves around The Minglong Diagram, which is divided into nine parts. The first six diagrams correspond to the cultivation system of "muscles, bones, skin, essence, qi, and spirit", while the last three diagrams are related to the Daoist realm of "refining qi to transform spirit". This diagram has become a core treasure fiercely contested by various forces. Ye Jingtang holds multiple identities, including Deputy Commander of the Black Yamen and Protector of the Pingtian Sect. Relying on the Chi Dragon Saber and the Minglong Spear, he earns a place on the "Eight Great Chiefs List". In the end, he gives up ascension to immortality for his beloved and pacifies the chaotic world.
