tldr; Don't read this manwha if you expect an op mc to actually do things. Or a knight to be good.
Mc is a middle aged man, used to the unfairness of his world.
Used to be the sole survivor of a monster attack on his school due to guilds being manipulative and greedy. So it's quite understandable he doesn't trust them at all.
One day, just like that, he gets a very op awakening as a Knight. He has to follow knightly values and such to gain rewards. If he doesn't he is punished instead. MC therefore proceeds to not be knightly at all.
His first thought is to use traps, ambushes, fighting from range, etc etc.
Does he get better at some point ?
So far as translated, he's even made deals with a demonic constellation, and spared one of their apostles.
Everything good he's done as been because he was basically blackmailed into it.
He is already the strongest awakened in the world (apparently, we don't have much informations on the world) but still wants to run away when there's an alert.
It's basically a manwha where everyone other than the mc is evil and tries to screw him over for their greed.
But the mc himself isn't great either so it's kind of a murky nonsense were you don't cheer for anyone.
It really felt like reading a manhua where their overdone young master tropes and such. But no, apparently it is korean, not chinese.
There's also not really any kind of world building or character development.
All we know about their world is that someday monsters appeared, there's portals too somehow, and constellations both bad, and very bad.
It's a world with no good people at all (ok, aside from the waïfus of course, since it's an asian thing...)
The only thing the mc seems to enjoy doing is grinding his levels, which he gains very easily.
Frankly it's boring.
