As the notes danced, a certain ripple, visible yet seemingly invisible, began to spread around.
This ripple carried a certain sound.
Even though this sound seemed to carry no expression, it was neither music nor speech, just a pure tone.
Indeed, this treasure was merely a pure sound, akin to sound waves.
In harmony with her treasure, it was quickly mastered by her.
This sound that was silent and shapeless disappeared.
Then Julia opened her eyes.
"Very suitable for me, yet a difficult treasure to master."
Because what this treasure represented was simply sound. To evoke the desired abilities, one must delve deep, master, and think about how to integrate it into the desired system to unleash the intended functions.
All of this requires time and proficiency.
And this time, Julia simply waved her hand gently.
Her hand stirred up the sound of the wind.
And under her control, the sound of the wind turned into musical notes.
