Review Detail of Ninth9 in Shadow Hack

I cant completely say it was trash because in my opinion it was very good up until about chapter 600. Like i mean good enough to the point i would have gave it a 4 star on average. After i read past 600 i wanted to give this novel 1 or 2 stars but didnt because it was good for 600 chapters. Reason it became bad past 600 is because the author gave up on what he had built up and completely changes the story into something that has bad progression, nonsensical plots, and bad quality of writting. Example being when out of no where it became a syfy where gods arent real gods but powerful a.i. built by humans ect ect. Then it spirals worst into a harem collector, dumb mc (who in my opinion was pretty smart before), and now not so good system. So at 620 i dropped this book. Would not recommend and only reason it got this high of a review is becauseof the past 600 chapters.
