Review Detail of Trident in Transported in an isekai world with his class

Mr.Author, I'll be honest with you. Your idea is good but unfortunately, it's an old idea. Furthermore, even though your idea is good you did not execute it well enough and to add salt to an injury, your grammar is extremely broken to the point where I, a reader whose English is my third languages could perceive how broken your grammar. I know my review is somewhat harsh but I did not have any intent to discourage you or stop you from writing a novel, but I really do encourage you to learn and fix your English and sincerely wish you luck in your journey to great success. And I'll appreciate you more if you did not delete this review of mine.
