Proving one's status starting with magical girls

Yuan An died suddenly from staying up all night, but his remnant soul attached itself to a cracked, bluish-gray mirror, drifting into a magical girl world where hope and miracles coexist. In the turbulent city of Linjiang, beside the green belt at a crossroads, a girl who longed to be a magical girl accidentally found this mirror. Thus, she began to impart the Dao of Immortality and magic, ushering in an abstract era where immortal techniques and magic were mixed together... "Qun'er, you must know that all methods originate from the same source. The incantation for a magical girl transformation is the supreme method that communicates with all things in heaven and earth. Only by reciting it can one become a magical girl." "...Master, do I have to recite it too?" "That's right." Li Jiangqun took a deep breath and could only grit her teeth and recite the incantation that her master had written for her. "I honor the Dao of the Sun and Moon, and embody the Five Virtues of Heaven—" "In short, above and below heaven, I alone am supreme!"
