In the continent of Ryuzakinus, the seven-color hierarchy divides the strength and weakness of all things, but the divine music master is regarded as useless because of his inability to fight. The young Su Mo has been living with his fisherman in the blue sky and sea since he was a child, with only a Qingtong Qin as his companion. The sound of the piano flowing from his fingertips can cause the fog to move and summon seabirds, and it contains unknown magic power.
When he was in danger in the forest, Su Mo's piano music actually delayed the attack of the red-level monster Lietooth Pig and saved the soldier Lu Ran. This made him realize for the first time that the music of the divine music master could not only soothe the mind. When Lu Ran mentioned the town's talent test, Su Mo's dormant curiosity was awakened - his piano music might be able to subvert the world's understanding of divine music masters.
The dragon's roar in the depths of the blue sky seems to be a response to the sound of his piano; the moonstone inlaid at the end of the piano will glow in seven colors under a specific melody. From the trial of the Red Level to the peak of the Purple Level, Su Mo will use the lyre to play his own legend. He wants this continent to understand that the sound of the piano can not only soothe the soul, but also shake the heaven and earth, tame the dragon, and become a new power that surpasses traditional martial arts and magic. This is a story about a child rewriting the rules with the sound of the piano, and it is also a heroic hymn that spreads from the shores of the blue sea to the sky.
