The history is good but there is something inside it that almost destroys it entirely, it's a feeling of irrelevance and unrealism.
The relationships are too shallow, yes the author tries to make them realistic and make it so they have a logical progression but he's not really good at it, it's not bad but it's not even close to good either.
For the fights and the drama, it doesn't work for the simple fact the author doesn't make it seem like the Mc will ever lose, in a good history for example every battle is a question of who is going to win but in this fic, the feeling that the Mc is always going to succeed the whole time.
And the reincarnators? well the author could have done something amazing with them he just made the main enemies (Reincarnators) seem like imbeciles like they are not something to worry about.
He did it so much that the foreshadowing of the final boss became irrelevant, the Mc is going to win and not lose anything why bother paying attention.
The author gave his opinion on SI's through the MC and his writing was affected by it but honestly, in doing that he almost destroyed the entire fic.
The main enemies could have been cautions, the Mc could not have the system say where they are located so the history could have had a taste of mystery both to the MC and us readers.
Each fight against a reincarnator could have been something hard, the Mc could lose, maybe the fight or maybe something related to her, it would have introduced a good character development, and a good training montage/arc instead none of this happened.
Anyway, in my honest opinion, this is an above-average fic but it could have been much, much better.
