She once had a name, Ed Liuhua, and she was an ordinary magician who controlled some relatively rare magic. However, in order to save the world and fight the Demon King, the brave man created a space-time rift around her home, allowing her to accidentally travel to this different world and become a little baby...
Although she can still use magic like in her previous life, and her portable warehouse has been brought to this world, she is really just an ordinary high school girl.
(The heroine's character is not perfect, because some reasons in the previous life can even be said to be selfish, but because she was born noble in this life, in order to behave in line with her status, she will say some polite words, but she still doesn't like others to do things. However, she will not be stingy with her true friends, but even if she is reluctant, she will always do what she says.)
Very nice!
