Have you ever or read or seen a piece of literature and went: " wow the characters are all dumb for falling for that" or " the mc appears smart but that's because everyone else is brain dead." ?

Well not in here.

All of the characters are smarter than you, even the ones who are not geniuses still have common sense and in fact making them brilliant will not be consistent with their character.

Have a theory about the current circumstances? 

The mc has dozens.

Think that there's a conspiracy brewing in the background? 

Wrong, it's at least fifteen levels of mysteries on top of each other.

That's just a single aspect of the novel.

The mc is (in my opinion) one of the best in all fiction, Because he's simple.

He's realistic.

He likes money but is still aware of it's actual value and will spend it ( with a bleeding heart) on what he believes matter.

He loves of women but still respects them.

He is a man of justice but he's not delusional.

He will kill those who believes are monsters without flinching and still be kind to those who deserve it.

His goals appears simple, but at the core everyone goals are in fact simple.

This grounds him into a realistic standard.

There is also the world building, the power system, the emotional stakes and the novel descriptions.

Unfortunately I have  been yapping for too long in this review.
