Nan Fengyi is the last descendant of the Feng clan and runs a wind chime shop in the corner of the city. She can understand the language of the wind, and every gust of wind carries news from afar. The peaceful life was broken by a sudden draft - the wind screamed the truth of the Wind Clan's destruction, and the murderer's voice actually came from the person closest to her. The wind chimes are jingling, and the murderous intention is approaching. She must find the murderer hiding around her before the next gust of wind takes away the secret.
