First off I have to say that I have read all four books htat are out right now and am a little miffed that they split them into four books. Honestly it seems like books 1 and two were one book cut in half and three and four were cut in half to sell more books for more money. I mean let’s be honest in book one some stuff happens but not a whole lot of progress is made by the main character accept getting into copper. This book he gets into iron and the ending feels different than book one. It is a good ending and leads into ook three nicely. Same thing happens with book three to four only backwards. A lot of progress is made in book three but then ends with you waiting for a duel. Book four not a lot of progress is made with the main character accept the duel and him discovering stuff and becoming resolved to reach the peak of cultivation. Again book four ends well vs book one and three. Am I the only one seeing this? All in all the series is worth the credits.
