Review Detail of hungerpig in I Cultivate Passively

Its very DARK be warned, if some things don't make sense they will be explained. There are twists and turns and is a lot of fun. BUT like 200 chapters in the author realised that the mc's power becomes super op over time so he decides to reduce the mc's IQ. Before it was about "I am going to die if I don't cultivate super fast" but now its about "I can live 1000s of years and be safe BUT f that am going to call myself god under the heavens in from of people that can 1 hit kill". he becomes as dumb as a rock also these were said 5 chapter apart "i don't have time to waste" (he is talking about 5 sec here)"i have all the time in the world"
