I won't say this is the best or most original novel here but i will say its one of the best (If not THE best) executed novels on the website with very few weak points, all the scenarios the author sets up are engaging, all the fights are rock solid and thrilling, all the powers are comprehensive, diverse and well thought out. There's 0% fat in this novel, nothing ever feels like "Filler" or unnecesary (Besides maybe the skill descriptions that you can just skip if you already know about it)
As for weak points (Author, if you see this, i hope you take these in consideration), there's only 2 of them and they're easily fixed, the characters have little going on besides wanting to be stronger, which is understandable since they're thight on time, but having them do something else besides training and bicker in the background would be nice, playing cards, watch TV (There should be some kind of entretaintment besides VR capsules) or even go to a strip club would add some life to their characters, given them a hobby or something that has nothing to do with getting strong, have them interact with other people and see how they solve their problems without the MC, have a bit more chapters about them and what they think of their situation and what they want to do with their lives, but its not urgent either (And its not like he didn't do any of these, i just think its lacking).
The other weak point is that the world, although well thought out so far, also has little going on besides getting stronger/richer, not that there's any problem with that since since these are all broad strokes about the setting and its factions we are just getting to know, so far the framework is solid but it lacks color.
All in all i always felt execution always trium** over originality and this is the closest to a 5/5 in execution i saw so far, great stuff, i hope he doesn't drop it.
