I love how consistently hypocritical this story is. And by love, I mean loathe.
The only mentioned sect rules are constantly ignored (No infighting, killing is only allowed in a specific duel arena), and everyone and their mother who arent besties with MC are either bootlickers, or malicious extortionists that get offended when people don't let themselves be extorted.
It also seems entirely formulaic; MC shows up, another guy wants something of him, MC says no, other guy goes all 'How DARE you not give me things? You're just a piece of trash!', surrounding reaction people also go 'lol he should just give in, he's just a piece of trash', then MC curbstomps the opponent and people are shocked. This just seems to be on a constant loop.
