I hate to once again be the bearer of bad news, but those "Trial Reads" too are about money.
Positive reviews and popularity might have some influence, but the biggest factor are the donations.
If you want to read an apocalyptic novel though, try reading "God and Devil World".
It's been completely translated and I thought it was a fun read.
You'll have to look elsewhere for the first 200 or so chapters, because Webnovel is not hosting them.
They just labelled chapter 193 as chapter 1 and pretend they have the full version.
Just google the title and you can easily find translations of the earlier chapters.
It starts with, "Chapter 1: Special Summon Skeleton".
