A heads-up before my review, I only read a fair amount of the translation. Most of it was in the raws. The reason for my low score is due to quality drop in the untranslated portion. An important note is that the translator is splitting up chapters, as seems to be common on WebNovel nowadays. So expect the chapter count of anything I mention to be at least double in the translation.
The story starts off fairly slow and uncreative. However, as more characters are introduced, and they start new simulations, the story improves a lot. It's fairly interesting to see how the characters change the timeline, as well as how their actions influence each other.
There is a downside to this though, as the author likes to repeat a lot of the things that happened on previous attempts. It's obviously just padding/filler. He also drags on when talking about the rewards characters get for completing the simulations.
At this point, I'd still give the novel a good ol' 4 stars (which is a good score).
Unfortunately, after around 210 chapters (raw), the author suddenly had what appears to be writer's block. For a while, I thought he dropped the novel entirely, but he just released chapters sparsely. It would have been better if he went on hiatus.
I got to a little over 240 chapters before giving up. It was over 30 (non-split up) chapters of tens of thousands of year time skips in the simulation with no explanations of any story events going on, rewards are exaggerated, presented in a troll-like way, and outright skipped, and basically everything in the real world is people being amazed at the various characters group.
This isn't an exaggeration like people like to do about cultivation novels. This is LITERALLY ALL that happens during those 30 chapters. Absolutely nothing about the simulation world is explained in that time, just literally "several thousand years later, she broke through. Several thousand more years later, she was surrounded and killed". No names are even mentioned in the simulation aside from their real names. Rewards say things like, "an insane, insane, insane amount of spirit stones. Amounts beyond all belief. Amounts that would make an entire city of people satisfied for generations. A city, do you know just how much that is!?" In the real world, nobody past Nascent Soul has been seen or heard of, so once everyone reaches those levels, along with their rewards, there is no threat. The author doesn't bother to introduce any either, so nobody dares to do anything aside from marvel at their growth.
Even worse, it doesn't seem like this would change anytime soon. It deserves absolutely only 1 star at that point. So giving this story 3.0 for a good first arc seems more than fair. Maybe even a little generous for people who prefer ratings to represent the entire novel.
