This is a legend about the fairy and the piano. There are two schools of immortality cultivators in history. The male immortals practice using swords as immortal weapons and advocate rebirth in the world; while the other school, represented by the female cultivator Fanghua Palace, advocates the combination of rebirth and joining the world. Over time, there will only be Fanghua Palace in the human world, and all the male monks will fly overseas and no longer return to the human world. The land of humanity has been forgotten by them. Over time, the customs and strange appearance of the human world have also changed greatly. From then on, women awakened and began to take charge of their own affairs, and there were many queens all over the world. Since then, the human world has entered a matriarchal society again since primitive society.
