Manga and Anime

Am I right to assume that it follows the web noval route and not the light noval route coz I was wondering why they went different from the light noval.

The timing of some events is mixed up even in season one.

Appreciate the conformation.
I only watched the anime and read the light noval.
Infact it was my first light noval.
And the light noval was so good I got hooked.

By the way, have you read all of the web noval and if yes I would like to know how do story goes in the later parts like the dragon king stuff.
Was that in web noval or was it an improvised verson of events.
