The young Muchen was born in Muyu, one of the nine domains in Beiling Realm. His father is Mufeng, the domain master of Muyu, and his mother's identity is mysterious. Although Muchen was born without spiritual power, he worked hard to make progress. Together with his friends Liu Mubai, Tan Qingshan, and Tang Qian'er, he entered Beiling Academy to study, and met Luo Li, the goddess of the Luoshen clan. Later, during the course of studying at the academy, he accidentally formed a blood link with Jiuyou, a spirit beast with the blood of the ancient phoenix, and fought side by side. As the Nine Eyes of the Evil God lurking in the world gradually appeared, Muchen, Luo Li, Liu Mubai, Tang Qian'er and others continued to upgrade their strength in the battle of Muliu, the black dragon besieging Beicang Lingyuan and Baima City. In the end, every teenager in Beiling Realm grew up, and Muchen also joined hands with the teachers and students of Beiling Realm to fight against the Evil God, protect the peace of Beiling Realm, and finally grow into the "Great Master" of the world.
