I remember Kronii clarifying in her Marshmallow the other week that she keeps up on over 200 webnovels with ease because they're all in one place and relatively easy to follow. So out of curiosity I went and made an account on WebNovel because it's barely talked about on 4chan and sure enough, the site keeps track of literally any story you click on, even if you don't actually read it the API will mark it on your account.
I'm not saying she's bluffing about reading that many novels at once, it's true that the reading level is elementary school tier and all plots are roughly the same, but when she started counting up all the books she was reading she neither mentioned if she had finished any OR if the stories themselves were finished.
Maybe it's just me but the most contentious part of her trying to flex about reading so many webnovels is that she doesn't specify their length. My Vampire System is 4x the length of Solo Leveling which is already a fairly lengthy webnovel, but the average romance and chuunishit you see on that site is like a third of that length.
Basically I'm thinking she only keeps up on like 10 novels periodically and the rest she probably binges every other week, like most people who read manga, manhwa, etc tend to do. Plus it's not like the number should matter, if you aren't retaining anything then it's no different from making a
Last.fm and scrobbling 1000s of songs without actually listening intently.
