Another story like "Last Human", monster apocalypse, monsters by tears, humans eat monster cores to cultivate and gain skills and so on, plus special ability treasures. It's done more seriously, more "mature" one might say, has less dumbness and doesn´t have comedy, which I prefer over bad comedy.
Characters are ok, a bit two dimensional and there is as far as I've read, no development. There's also a feeling of the story being in fast forward, something quite common in novel adaptations (I don't know if it is an adaptation but I'd bet it is), there seems to be small skips in the narrative of the story, nothing terribly noticeable but it leaves me with the feeling of things half explained.
Overall, the best of this kind of post apocalyptic cultivation stories, I've read about 6 of them so far.
