According to ancient legends, the daughter of the Phoenix comes to the mortal world once every five hundred years, and is reborn in the mortal world once every fifteen years. When her abilities are awakened again, she will be the master of the three realms. Many demons in the underworld will take advantage of this time to find the Phoenix Daughter in Nirvana and kill her. After obtaining the Phoenix Daughter's essence, their skills will be greatly increased. It is said that when the Phoenix Daughter is reborn from nirvana, a hundred flowers will bloom and a hundred birds will sing.
