Place it as the final beat of an edit, after a short build-up from Sudden Suspense and a passage from Sad Violin, so the quote closes the sequence cleanly and leaves the ending uncluttered.
关于此声音
This is a short spoken closing quote lasting just under three seconds, delivered as a single final line that lands with quiet finality. It feels reflective and a little dramatic, the kind of line that makes a pause feel deliberate rather than empty. Its brevity gives it weight, so the words carry the moment without needing any extra explanation or buildup around them.
