The "Song Kee" shop in the deep alleys of the old streets only accepts special business - visitors don't ask about their symptoms, and only use Wensong to insert a silver stick into the ear canal.
The tremor that others couldn't hear was a clear code in his ears: a pocket watch gear with bullet marks stuck in the ear canal of a descendant of a warlord, repeating the secret of the assassination every time it turned; half a piece of audio tape buried under the earwax of a popular actress, and the curse of seven lives hidden in the noise superscript:3.
"The ear canal is the mirror of the human heart, and the bones never lie." Wen Song wiped off the blood stains on the silver sign, and the footsteps of the next customer sounded at the entrance of the alley.
