First, it appears that the author may have forgot about the Demon Balrog who followed the MC to the Madelyn plane. Unless, I missed something in the MTL (which is possible) we never read about him again, unless the Balrog died along with the other psuedo-snake God, Cthulhu Cult God. To me, I'm glad the Madelyn arc came back into focus, but, I didn't quite understand everything that happened there--was the entire plane a prison planet--so besides the imprisoned Titan-Dragon egg the other four were trapped in the surrounding sea? If this is the case, then I feel it was a lackluster ending to the conflict.

Similarly, what exactly happened to some of the rest of Amos' other enemies. To me, it appears the author lost interest in dealing with them--unless, this was an intentional choice by the author to show us that sometimes things aren't always wrapped up in a nice bow (but if this was the case, then I wish the author would have been more explicit about it). In particular, what happened to the Snake Demon Abyss Queen after she retreated with her injuries and what about the Dragon Cult? Earlier in the story, it seemed that the MC would pursue/expunge the Dragon Cult in vengeance for his mother and because of the threat they posed to dragons overall. However, the focus later shifted to the Titan-Dragon war so I understand the distraction.

Lastly, I found that there appeared to be a missing Divinity and/or Abyss Arc. Not only did the story not end with the MC becoming a God (which many authors in the genre do) --but there was no conclusion to the demon war--or even the Titan-Dragon conflict. (Although, if fairness, the Dragons do seem to be the overall victors). It seems the author didn't want to give enough time to write out all everything that happens and/or lost interest. Another example of this is that when the MC is trapped in the abyss, the MC's clone passes one or more of the other winter trials without us seeing it and his potential to be the successor to the Ice Elemental plan is handwaved with Amos concluding he never wanted the position anyways. (I do understand prioritize his main body's life over potential future power, but I wish we got to see those trials and/or understood all of his thought processes.)

Nonetheless, all of my critiques could be irrelevant, since it appears, upon research, that this story is set in a greater Shared Universe. If this is one novel among many, then I don't think there is or should be pressure on one author to tie up all the loose ends. It may be more interesting to see what becomes of Amos, Felicia, Elena, Willy, and all their friends, subordinates, and enemies in other entries of the series. Moreover, I know in my haste to read the novel and due to the difficulties of MTL, I most likely skimmed over or misread key details.

The MC is born with a system that scans everything and that, I feel, takes away all the cool things the event could have been. Like, imagine, if the character was a super genius in comparison to the super idiot character trait of his species and he was doing all the analysis of items and coming to somewhat accurate conclusions? (this could have also been interesting to see in battle since he could have made an incorrect assumption of the object and backfired on him and he has to turn the tides even more so) and he was one who had clever battle tactics like playing 3-D chess? That's the system doing all the (correct) work for him.

It all escalates really fast, one paragraph he's chasing a defeated enemy, a few paragraphs later he's on the brink of death and then he pulls some new skill out of his ass to survive. Do you want an explanation of the new skill? Simple, >>> Inheritance <<<, you don't get explanation before or after about such ability.

Was the system really necessary?

It's a little difficult for you to care about the MC because he is narrated in almost the same way as any random character.

And it seems that it will follow the same path as "The crimson dragon" which is from the same universe, even the way of acting of the two protagonists of the work is similar, but it has its differences, for example the protagonist is not a character without emotions and feelings, he cares about his brothers who by the way are charismatic.
