In the demon world, our heroine, Ye Yaoyue, was born in a big family. Her brothers and sisters have made great achievements in the demon world, but she has a "magic immunity" that is rare for demons in thousands of years. She cannot use magic, but magic will not cause harm to her. At this time, there was also news about the "glazed bead", the most precious treasure in the three realms. In order to retrieve the treasure, Guangda Demon Clan also wanted to train Ye Yaoyue, so this glorious and arduous task was handed over to our heroine... And then our heroine came to the world "gorgeously". And study in the 'Moon Night Academy', but things are often not as simple as imagined...
