A melody created by the Ye He Na La Family that has the ability to purify the demonic powers and instincts of a demonic power-user. But subsequently, the power-user will lose his powers. Should he ever get his powers back, they will be different from the ones he had before. Aside from this melody, there is also the Soul Collecting Melody (蒐魂曲) and the Soul Calming Melody (安魂曲). Ye Si Ren is the keeper of this melody as well as the Soul Collecting Melody.
