Fairy Sound

In Yuefu, there are two different levels - Xianyin and Yunnu. Immortal music, as the name suggests, is music that only exists in heaven. Only one person gets this title every ten years. Rhyme slaves only have the appearance of sound but no soul of music. Those who cannot become immortal will become rhyme slaves. There is no one in the Yuefu in the world who doesn't want to become Xianyin. Conception:
