In my opinion, I think it's progressing normally if we think about it. I believe the major plots start after the introduction of the more important characters. For example, one of the biggest mysteries so far are the three top 10 who fought against Kayden. However, before introducing those characters, we need to meet the other top 10. At this point, we already know 6: Veramonte, Supri, Schneider, Andrei, Astra, and Guestella. This means we still need to meet 4 more. Three of those 4 are probably the ones who fought against Kayden, and the last one remains a mystery. So, I think it's progressing normally.
its been 300+ chaps and there hasn't been much actual plot development. Mc meets someone, gets beaten, kayden saves. Mc decides to train and repeat and repeat and repeat. They keep dragging the story ON and ON in circles(#)
