Everything in existence sings—the whisper of wind, the pulse of steel, the hum of the unseen. Reborn into a world of cultivation, Cai Feiyin awakens with a gift unlike any other—the ability to hear the oscillations of all things. To him, the world is a song waiting to be understood, shaped, and mastered. But in a realm where power is forged through blood and will, those who hear too much may uncover truths never meant to be known. And some songs, once played, can never be silenced.
