Yu Lingxiao is Xianchi Xingjun's apprentice. She was originally a thousand-year-old Xiao. After her memory was wiped, she became a fairy who helped manage marriages. Due to an accidental fall into the mortal world, Yu Lingxiao reunited with Youqin Xingjun (Mo Wenqin), who had been traveling in the world for thousands of years because of suppressing the evil spirit of the Seven Kills. The two of them coincidentally became musicians in Huamanlou in the human world, and discovered that their piano and flute playing together had the healing effect on people's hearts, and could soothe and purify the hearts of more confused, fearful, and sinful people. In order to earn a living in the human world, Yu Lingxiao, and Mo Wenqin, in order to accumulate merit in the human world and return to the immortal position, opened the "Qinxiao Medical Clinic" and worked together as "medical doctors" to help many people. The latter two worked together to eliminate the evil spirit of Qisha and restore the memory of their love for each other thousands of years ago. They lived in seclusion in the fairy world and lived a harmonious life like that of thousands of years ago.
Purpose: The human heart needs to be healed; even gods who come to earth must rely on their own efforts; relationships need to be managed slowly to achieve results.
