The only reason to watch this is to compare it to the book and see what an utter waste of resources this animation is.
I have read all the books of Er Gen except A Will Eternal, and then I stumbled upon this series and was overjoyed that something like this exists. Then I read the other review here that praises it so much that the sweetness drips from my display, so I knew that this is a must watch!
By the time I got to the 30 episode I felt that something was off. The main character was absolutely inconsistent and weird, not in a good way that defines a character, but because of the bad writing, and I knew there's something fishy here because Er Gen doesn't do these silly mistakes.
When I encountered the weirdest arc change I have ever seen in my life (the one involving a certain mask and another sect), I knew I have to read the book to see if it was just as weird.
And what do you know - turns out the producers added, removed and revised so much that they butchered the whole plot and made it incomprehensible to anyone with more than two brain cells. Xiaochun is a bipolar crybaby Marty Sue, and every plot twist is a Deus ex Machina with no explanation.
Thank God, Er Gen didn't disappoint, and now I'm really enjoying the book. I recommend to do just that, it's hilarious.
