Yes, everything is as written below.
Cheap, frank, flourishing, easily exposed evil and slander, which for some reason everyone believes, except for some particularly advanced deep old men who with great difficulty admit: "Yeah, maybe this guy is not so bad."
I guess why MC was so eager to cure his grandfather that he crippled everyone in his path. He received a bunch of bonuses from an unknown source for this, the grandfather's intercession and madly expensive gifts from the grandfather.
Grandfather, by the way, is also suspicious. If he is so good, wise and insightful, how did he tolerate such crap in his family before? They all did not become like that yesterday.
And for some reason MC will save this world, although he should have helped it die. Was he born with a bruised head or is his brain so washed by propaganda?
This world really needs to be cleansed. Even MC's mother, who left him such an interesting bead, clearly did not suffer innocently, but simply did not survive the natural selection.
Happy ending here if MC killed them all and died along with his soul during the next ascension.
Not that I enjoyed reading this, but I give what is due.
