I apologise, but I'll start with this. How about a novel where wits and brain have value? And what if 'system' existence is not only explained, but also it's limitations are shown?! Oh, and how about MC not being the 'chosen one' and more of a lab rat in greater being game? What if his grand schemes and plans have some flaws, so he can lose and LEARN from it? Great isn't it? Now to the long one. I'll try to do it without spoilers.Writing quality is good, not perfect (there were some insignificant typos), but hey, nothing is. It's easy to read and writing gives characters their own flavour. Speaking of character design, it's good enough. Main and notable characters are quite interesting to watch. They have their own arcs and don't do things that contradicts what they did so far for the sake of plot development. Less significant ones are not as bland as typical 'young masters' which is good enough for fillers. World building is great and is shown slowly as MC gets more and more (it's a good way, because we as well as MC don't know anything about the world, so other characters can explain to him stuff that also explain it to readers) story develops. The world or worlds to be more correct are a gargantuan part to explore as it should be if you use terms as demi-gods or plains. But this novel in terms of giving that small fly in gigantic world vibe is one of the best so far (maybe one Warlock drinking tea in abyss can argue). So, overall with this rarely seen in novels concept of battle of wits, huge and vibrant world (that does not change just because) to explore with interesting developments so far the novel does the trick.
