Review Detail of Kvothe_the_wind in Lord of the Truth

It's not very good. The english is broken and it's too difficult to read. The power system isn't clearly explained. I know there are numbered levels. There are knights, saints and sages. But what they can do or what's the difference between real is never explained. The world is unknown. We know some countries and cities name but we don't know where they are. The characters aren't very well constructed. What are their aspirations ? What do they like? They power up and that's it. It's just cultivating and nothing else. The MC is "smart" but he makes stupid decisions which works because the author makes him succeed. I mean, he is boastful of how quick he can make others cultivate and everything is fine because he knows others will see the benefits he brings, bla bla bla. But not everything is logical in life and you can't predict all things correctly. He shows too much while being too weak. I'm sure there are other things but I stopped after 60 chapters. I was tired to see power ups being too easy and too fast.
