"What is that sound?"
When Xiao Mu released the barrier in front of them, there was this strange sound that filled the air. It was a sound that hadn't been there until the barrier had been released, but it was strange that there was even a sound in the first place.
After all, it wasn't as if a sound like this should have been blocked to begin with.
From what they could hear, it seemed like this was the sound of an instrument. Only when they listened closely, it didn't feel like it was the sound of a single instrument.
It felt like there were different sounds that were laid on top of each other with how intricate this sound was.
But at the same time, there was something about this sound that made it clear that it was just a single instrument.
"Are there instruments that can produce this kind of sound?" Lin Fan couldn't help asking in the end as he turned to look at Ye Qing Huan.
When it came to matters like this, she was the one that knew far more than he did.
