Reborn: The Legitimate Daughter's Radiance

Looking for a Historical Romance Where the Female Lead’s Weapon Is a Flute

Please, I am begging for a book. The female lead seems to have transmigrated, and she also has another identity, perhaps as a young valley master or a young master of some sort. Her weapon is a flute or xiao. She can spin her weapon with her hand and make it play by itself. She and her best friend are collectively known as the Sound Venerables.
