Qi Ling (played by Chen Xuedong) was originally an ordinary boy in a small town in the Odin continent, until one day he met the second-degree apostle Shenyin (played by Yang Mi) and saw the legendary beast, thus starting a new destiny. It turns out that the Odin continent is divided into four countries, each of which has a powerful master of soul techniques. The most powerful person is called a prince, and the successor of the prince is called an apostle. Qi Ling was found by the seventh-degree prince Yin Chen (played by Wu Yifan) and became his apostle. Under the leadership of Yin Chen, Qi Ling began to practice and met the unruly sixth-degree apostle Tianshu Youhua (played by Lin Yun), the fifth-degree apostle Guishan Lianquan (played by Fan Bingbing) who has an important mission, the evil second-degree prince Youming (played by Chen Weiting) and the fourth-degree prince Treya (played by Guo Caijie). The appearance of the pale boy (played by Wang Yuan) made the secret of the disappearance of the previous generation of the first-degree prince Gilgamesh surfaced, and everyone began a killing battle to pursue the truth. In the dispute, the apostles and princes represented by Guishan Lianquan and Guishan Fenghun (played by Yan Yikuan) were caught in a hunt, while Yin Chen was determined to track Gilgamesh.
