Su Xiao opened a second-hand goods shop in the old street in the west of the city, but the business was bleak. Until she discovered that the old objects she had collected could lead to different worlds - the pearl hairpins of the singers of the Republic of China were connected to the Shanghai dance hall at night, the pocket watches of the anti-war soldiers led to the battlefields of war, and the diaries of the students of the Republic of China were followed by passionate parades. The owner of each object wants to fulfill their unfulfilled wish, and Su Xiao's mission is to help them get it done. As a result, antique dealers, historians, and mysterious buyers came to her door one after another, and investigators from the Three Realms Administration also focused on her.
