Review Detail of Wolvasa in Evolving into a Great Dragon From a Koi Fish

It was good till the last few chapters. The system started working as a strong plot armor. Really forcing the plot to move faster than it had previously. I'd say this book should have had another 200-300 chapters in it if it hadn't been rushed. If the author really needed to rush it, a few more chapters to straighten out the last of the arc and a few more to tie up the remaining loose ends would have left me content. As it stands, the ending was like a punch to the gut. Did something happen to the author ?
