Will the series keep being peak?

I'm just here to know whether the manwha will keep being peak. I'm more skeptical about long manwhas like these since Revenge Of the Iron-Blooded Sword Hound apparently had a pretty bad ending and generic arcs, so now I'm just wondering if this series is going to have the same fate. Also, a little extra, but I want to know if there's any difference between the manwha and novel that's substantial, and whether or not the manwha changed stuff from the source material that made it better/worse in your opinion.
