Seven 13-year-old girls, Yin Lan, Luo Minjun, Chen Laner, Ouyang Yue, Yuan Zichun, and Liang Xinying, met in a girls' school and became close friends. The friendship of the seven people moved the newly succeeded Demon Queen, who gave them the opportunity to obtain the key to dreams through sympathy, friendship, and family ties. The seven people received the colors of magic, which are red, yellow, blue, green, white, purple, and silver. Several girls were forced to separate from their parents, live independently together, gain status in the world of demons and immortals, and defeat the God of War in the Qing Dynasty. They went through many hardships and finally reached the supreme level 10, earning the title of "King of Demonic Immortals". They understood the true meaning of magic, but due to its advanced nature, they did not teach it to others. They used the gems in their hands to return to their own time and space, only to realize that they had had a dream, but everything was there, including magic. The seven people discovered the unequal status of girls in society and tried their best to sacrifice the magic crown, the symbol of the tenth level, and 10% of magic to create an imaginary daughter's country. The fifth sister, Ouyang Yue, is the magic fairy with the highest magic after the phantom. She teaches a girl who hates all boring things, the blue fairy Lin Xiying. She took control of the magic empire and defeated the increasingly evil Fairy Queen. Her seventeen-year-old sisters worked together to seal the magic key, sealed it in a giant box with heavy magic, and hid it on the golden phoenix of the Fairy Palace. Only demon fairies who sincerely help others and are kind and honest in nature can inherit the magic keys of the seven of them.
