It took a long while for Xichun to collect herself, and she asked curiously, "Brother, what kind of treasure is this, exactly?"
Jia Yu explained patiently, "This is called a Magic Sound Box. It has five layers and twelve sides, corresponding to the five musical notes and twelve pitch standards. By adjusting the different settings, one can play all sorts of melodies. For instance, if you set the Gong note to the seventh slot, the Shang to the ninth, the Jue to the twelfth, the Zhi to the eighth, and the Yu to the fourth, then release it, it will play a joyful birthday song."
No sooner had he finished speaking than the Magic Sound Box, as if it had understood the instructions, began to rotate automatically, and a cheerful birthday melody rang out. The crowd was amazed, their eyes full of wonder, all feeling that this was truly a rare treasure, one likely impossible to buy for any amount of money.
