It's been awhile since i read that part of the novels so i could be forgetting something.
Right now the novel is about 2 arcs ahead the manga .
But most things that happens in the novel is here and it have not changed all that much.
so all in all i say its a pretty good visualisation.
Reading the novels is usually going to be better, but unlike some manga´s most sideplots and minor details are here as far as i remember anyway.
I belive we are around chapter 80 in the novel, and there are up too 327 as off right now.
If you want to start over you can catch up fairly quickly as a lot of chapters are padded with the stats of creatures etc etc.
But be aware that there is multiple people who translate the story and some are further ahead than others.
It took me a year to realise that the guy i was originally following were like 150 chapters behind the guy on wattpad.
Once you catch up with the translation(chapter 200+) i recommend you read here.
You can only read 200 and above here, but and the translators include the author's illustrations for extra visual goodness.
A Lot of sites that just copy paste the translation dont include the extra artworks and they are honestly pretty nice to have.
