Good for spending time, don't expect a lot of plot, the Mc is overpowered from the beginning, there's sometimes the story will get boring, but you'll just continue because the novel is about to end anyway.
Well, in the first world, the novel was not excellent, but fairly good to read, balanced, respectful MC.
After the MC goes to the upper relam, everything falls down dramaticly, even the MC characteristic change upside down. Everything is just worse. Like the Arthur was bored from it and gave it to a teenager to complete it.
