I completed this LN and I can comfortably say this is one of the best Chinese LN ever. I can understand if people don't like this kind of novel. But you have to admit this novel has a very good World Building, Very good story flow, Very good story and a very Good caracters. MC is not stupid in fact he is quite interesting. Most caracters are in this novel. World does not revolve around him. You can see people living life independently for him.
MC is op but not the strongest in the world, he becomes strongest but very late. But MC cautious never fiting against anyone stronger then him. He does a good job hiding his strength.
As for the villains thay always underestimate MC not because thay r stupid because MC is hidden well or thay even don't know about him.
In the end this story doesn't get worst as it goes on but gets more exciting as the world opens up.
Only advise I have if u want to read this novel don't read on this site translation is very bad hear.
