Part 3:
With all of my rants about how absolutely horrible the first 300 chapters or so were, I can confirm that it does get way better from 300s and onward. I don't know what type of substance the author decided to shoot up but he should definitely do more of that, because the MC finally starts thinking on his own and decides to take matters into his own two hands because he realises he won't be able to get anywhere if he just keeps on depending on his cheat code. He fights his own fights way more often (even though the average amount of fights is still below other cultivation books), and his character becomes more dependable and less naive compared to the beginning.
One other that I liked, aside from the author fleshing out the world by introducing a somewhat intriguing plot, is the different inter-relationships between the clans around the MC and how they interact with each other.
