After being bound to the entertainment system, Mei Mei lived a life as a clerk. "Beauty, do you have any requirements for the songs you create?" "It's just that kind of salivating song that is popular and has a pleasant melody!" "It's very popular... The melody is pleasant to the ear... I understand, please accept this song "Lanting Preface"." … "Is he the talented musician Xu Qing?" "I heard that he created a masterpiece that shocked the music world in half an hour!" "Mr. Xu, what do you think of the divine song you composed?" Xu Qing was slightly dazed and said calmly: "It's just a popular saliva song with a pleasant melody."
