Review Detail of BluePen in Shadow Eater

Hi dear readers. I am the author, BluePen. This is my first novel, and English is not my first language. So I hope that it won't annoy you. I shamelessly rated my novel and gave it 5 stars. But, as I can see, I am not the only one, most of the new authors are doing it. After all, People love seeing their work succeed. (it would be impolite if I make an exception). By the way, how many reviews are needed for Webnovel to show the ratings?
