This story is the peak of deus ex machina(a.k.a Random BS Go!!!) if I've ever seen one. Almost every conflict and problem is resolved by introducing a new element or character instead of with wit and determination. None of the characters hold any weight in the grand scheme of things. You just know that some new BS plot armor will save the day no matter what.
The world-building is a huge mess that lacks any consistency and logic. Again, new elements and characters keep getting conveniently introduced and immediately dropped/killed off once they're no longer useful to the plot. Even the leveling in the game system is a unsalvageable mess. I mean, gathering stories to gain power is a truly unique concept, but...
I'm a sucker for the "game-like" and OP MC trope but this is just not it. I had planned to keep reading the manhwa till I'm caught up with the latest chapter then continue reading the novel but I don't think I can make it that far.
Edit: OK so I lied. I went on to read the novel, thinking that it should be better than the manhwa (novels are always better, right? Right??), and I actually made it to 60% before finally giving up. It really didn't get better... In fact, the Random-BS-Go got even more random, and the BS grew to ES (Elephant S). Entities from the whole universe b*tching on social media all day long bla bla bla, lack of "Probability" bla bla bla, swinging gianormous and micro stories in each other's faces bla bla bla. Rinse and repeat. Maybe it's just lost in translation? I'm not sure. But one thing for sure is that I've given it my best shot and it's just not for me.
