Review Detail of Own in Villain Cultivator

I really liked this story at the start all the way up to when he fled from the brothel. That's when the story did a nose dive and went subpar. The main character Mao used to be scheming and cunning. Now he acts like an idiot with 2 brain cells. The chapter I'm up to he takes out some divine quality ingredients in front of his enemies family and his grandma-in-law who has a questionable personality. I mean how naive can you get? There are a ton of things that just keep piling up, I can't read on anymore. I just wish the author made his personality consistent instead of this mess
