Sorry to tag you randomly. But do you know where I would continue in the Light Novel if I wanted to keep on reading from this part
If you still need it, both this chapter and also, the anime are currently about halfway through part 3, vol 3.
There are however a lot of minor details and world building aspects that are skipped in manga and anime both, like the bell based time keeping system as an example.
I personally jumped from the anime and mangas into the last part 2 LN back after the anime overtook the manga and finished part 2, but ended up going back and skimming the earlier books, to get those details but also to read the side stories and alt perspectives that are common in the LNs. An example of those would be the first season of the anime including a few of those as OVAs.
Hope it helps, if you didn't already find out
