Review Detail of IcyTurtle in The Ultimate Evolution

I have read until the end of the book and there is only one thing that I want to say "The last arc is awful, the ending is ultimate let down." My advice is to not read this novel as the ending is so rush and bad that it remind me of how bad the devil's cage ending is. I did not read this novel on this site, but since I'm active on this site now I decide to give review in here as by the end of the day I already read everything about it.
