Douluo see you

Just now a kind book friend reminded me that a book called "Douluo: Dream of the Ice Silkworm" copied this book. I went to read it, and it seemed that he copied all the first 25 chapters of me, one word I didn't change it. I don't know what he meant, but it's not appropriate even for book friends to do this, right?

Let me talk about it here. Don’t think of me as a pirated copy anymore. I’ll go to his comment section and ask him what he means. That’s it.
