Let's go. I don't know if the author has abandoned this, but I'll give my review anyway. As a good Brazilian, I really liked that the story is set here in Brazil, and the author spoke a lot of truths and described many things perfectly. But I need to say, brother, there are some things in the chapters that are unrealistic and don't make sense, and in the future, this might come back to bite you. First, the system: it's way too OP, and when I say too much, I mean really too much. First of all, letting the protagonist gain a power or knowledge every month is excessive. There will come a time when you won't have any more powers or knowledge to give him because you will have given everything. Imagine in 12 years, when the plot really begins, your MC will have 144 different powers. That's a lot, and the knowledge is even more powerful since he doesn't need to do anything to receive it. On this topic, another thing I didn't like was how easily the MC gets things. It's way too easy. He’s not struggling at all like a good Brazilian would. I’d prefer it to be a normal system where he actually has to train. We have capoeira that he could practice, but I mean really practice, without receiving it from his system. This will definitely make the MC lazy. And back to the system, there are so many things that I doubt you'll use half of them. Store? The MC will still be able to buy all kinds of things. You wrote in a chapter that there will be characters from other worlds. Another senseless thing, author. There are many interesting characters in DC, some of whom are even Brazilian (look them up). So I don't see the point in bringing characters from other worlds. Want beautiful women? Wonder Woman doesn't lose to anyone, author!
My final assessment is this: the main villain in your fanfic is your system. Everything else is perfect.
