On the day Shen Muyu died, the whole city's copper bells rang without wind, but no one knew that it was she who rang the last bell to bury herself. Xie Yunzhou's bell shop is as silent as a tomb, and in Liu Zhiying's recording pen, her sister's last words are echoing repeatedly with the sound of the bell. When Bai Mute Niang's glutinous rice cakes began to have blood characters on them, Zhou Yansheng's live broadcast was silent, and her heart beat faster and faster - it turned out that the bell that day was not a mourning, but a wake-up call. And Shen Muyu, in the body of a deceased person, is walking step by step towards the truth that Xie Yunzhou has buried for many years.
