This is one of those novels where the blurb is bad, but the story is even worse.
The MC has a very unlikable personality, which does not fit his background.
He was Reincarnated into a 3 year old orphan, but even after 10+ years he is still not used to his new life, is biased, sees others/natives as uncultured and acts like a visitor instead of someone born there.
He is extremely childish and bratty towards his master who raised him, but we as readers are supposed to treat him like an ***** with mad deductive and people skills.
I honestly feel like this is a badly done novel about a virtual reality game player who went back in time.
There is no sense of excitement or suspens, the MC is unreasonably capable because he has seen it all. Of course he has not, but the sense of danger or cation is completely missing.
The MC does not fit into the world the author tries to create and so it warps around him until there is nothing that makes sense anymore.
Let me give an example.
Imagine you race is getting attacked for no reason (in your mind) and you get sent to the enemy recruitment camp to scare of as many as you can. Sending a young and beautiful woman who is naive and incompetent is probably not anyone's first choice, but circumstances. Oh and killing is a nono, because they are still not murderers, only willingly trying to become murderers(your mind).
So you/she fail your/her task, would you/her:
a) Leave and hide to continue the mission with other targets.
b) Make an excuse, like pretending to be part of the examination.
c) Deal with the problem temporarily (knock unconscious, sleep spell etc.) or permanently.
d) Just leave to report back.
Or
e) Tell your target about your mission, the reason behind your mission, about the philosophy behind your actions, part of your life story and background. Thereby risking exposure of yourself and possible companions.
And accept the targets offer of food.
3 guesses which happens in this novel, and the first 2 don't count.
So far every character in this novel lacks common sense and basic logical thinking. Which is even worse for the MC because he is supposedly a very scientific kind of guy. He is searching for answers in a supposedly scientific way, but can not even observe the reality he is in.
I can't claim that the idea or the concept behind this novel is anything noteworthy, but it is so badly executed that I still feel really bad about it.
