Review Detail of August_Rayleigh in Level Up Legacy

I'm on chapter 600 now, I just picked up this book after not reading it for a long time, and I'm trying to get back into it as I remembered that this was an awesome story, but now I kinda remember why I stopped reading it in the first place. The main character is just so frustrating to read, he keeps getting schemed against and attacked but all he does is threaten people "I will kill you" but never does, even at the risk of putting everything that matters to him in danger, he is just so weak willed it's unbelievable. Also, he's supposed to be someone who is becoming emotionless, but he is losing control of his emotions every other chapter, and every interaction drags so long, I'm literally at the point where I just want to skip a few chapters, but I'm afraid I'll miss something important because it's hard enough to decipher the words as it is without skipping chapters. Other than that it's a interesting story.
