The Spiritual Contract Era is a fantasy world where humans and spirits coexist. In this world, some special people can sign contracts with spiritual bodies and use the power of spiritual bodies to cast powerful spells. They are called spiritual contract masters. However, different spiritual bodies have different power attributes, which can be divided into light and dark. The degree of compatibility between the spiritual bonder and the spiritual body also determines the strength of the ability. The various forces are fighting endlessly around the power of the spiritual contract. The war is about to break out, and the whole world is plunged into turmoil.
