First of all, the story shouldn't conflict too much with the Harry Potter world. . . I guess so. . .
Secondly, the number of protagonists is about five, including Harry Potter.
Third, there may be too many private devices.
Fourth, the writing style of this article is not very good.
Fifth, the character design may be a little too suave, but it seems a bit excessive to think that the trio could rob Gringotts in seventh grade.
Sixth, there are Eastern elements, but in terms of setting, Eastern elements are stronger than Western elements in the early stage, but most of them are weaker than Western elements in the later stage (after all, Eastern masters always like to hide their skills)
Seventh, the protagonist has a golden finger, but there are also situations where he is unwilling to use it.
Eighth, the characters of the protagonist are not perfect, and sometimes they even behave selfishly.
Ninth, the soy sauce "Joke with Mary Sue" is very good, go and watch it.
Finally, I chose the age category arbitrarily. Don't mind "under 18 years old". If you don't like watching it, please move elsewhere.
Purpose: For travelers, the HP world is real. Therefore time travelers are imperfect. So they have their own story.
