The statement has a secret: he can hear the sounds of both worlds. One is the normal real world, and the other is the "dark world" that overlaps with the city where he lives. The dark world is full of the remnants of the dead. They cannot speak and can only use their remaining "voices" to repeatedly play the memories of the last moments before death. As an ordinary migrant worker in the city, Shuo Shuo earns extra money by helping people "hear" the last words of their relatives. Until one day, he heard the voice of a person who should have been alive in the dark world - "I am not dead, I am locked in the basement." And that voice came from the only daughter of Zhao Heming, the richest man in Qingcheng, who had been missing for three years.
