It's honestly great, tho it may not be for everyone.
Imagine a sharp and creative man with no system, cheat or natural superpowers reincarnating into a fantasy world that has a roughly solid single governing body that maintains a perfectly thorough surveillance and censorship with the aim of keeping the order and balance of their world.

He'll suffer. He'll be pitted against people he's no match for. He'll struggle against the censorship and desinformation, trying to slowly piece together the truth and his situation. He'll be used and forced to follow orders. He'll also try to rebel.
While those things are obvious, based on the world's lore, that's what the reader needs to be prepared for. It's not a steamroll of an overpowered genius, but a careful and nuanced novel about finding a goal to strive for and the understanding reality one lives in. And revenge. All that woven in schemes and fight-action of course.

What really got me tho, is how everything had its cause and effect, which at times brought hilarious situations.

In general, it's a rare find and one definitely worth checking out, even if you feel you won't bite at the plot.

As a postscript, there are people trashing on the ending, but it is a hoax. It was great.
There are others who trash about him being a slave for the entirety of the novel. That's because they don't understand the subtlety of the book, and the fact that mc in truth never acted subservient, but chose to follow others' plans to borrow their authority as he didn't have enough standing on his own or just because of threats, but then he still did it his own way.
Finally, you'll find those complaining that there's too many twists, but that is a matter of course, considering how Isaac fights blind against the opponent who distributes information, and I promise none of those twists is there just to be a twist, but is a process that slowly teaches us about the objectives of various factions.

Enjoy.

Being a pawn for over 200 chapters, dude has to grow some balls.
