Thousands of years ago, the land of China was filled with spiritual energy, and those who could use it for their own benefit were exorcists. Their mission was to stop the demons that appeared once every thousand years from wreaking havoc on the world. However, in the Han Dynasty, a tragedy occurred in which the spiritual energy of heaven and earth disappeared overnight, which was known as "the return of all laws to silence". The exorcists who lost their power gradually withdrew from people's sight. During the Qin and Jin dynasties, wars continued, and the resentment of the wrongly dead became the raw material for the resurrection of the demons. In order to stop its conspiracy, Chen Xing, the last great exorcist in the world, embarked on a journey with the treasure "Heart Lamp" that resided in his three souls and seven spirits, and went to Xiangyang City to find Xiang Shu, the guardian martial god who was destined to work with him to exorcise demons.
