As a newcomer, the author is writing a copy for the first time, and he doesn't know much about the control of the length of the copy. The copy of the Polar Valley is about sixty or seventy thousand words, and most of you think it is too long or too short, or is it just right?

I hope you will move your fingers and leave a message in the top post in the book review area. Your message is the best feedback for the author, and the author will adjust the length of the copy according to your feedback next time.

Please!
