It started good in the first 3 chapters, went very downhill for quite a few chapters, then became pretty good for a while but as of chapter 86 it is just a terrible plot. I read spoiler reviews and nothing they mentioned made me surprised. The author has a hard on for his own people and even if like me you don't particularly care, he'll then send you down one lame plot after another and his MCs seem to always have a unique ability involving entering another world/space but there is always some lame rules/restrictions that are supposed to be a balancing aspect of the ability but doesn't really matter. This novel is possibly much worse than Castle of Black iron but I can't say for sure as I didn't even make it to chapter 300 before all the nonsense just made me lose interest. This story accomplished it much faster.
