Quite easy to understand why the whole Yun Lan sect is so corrupt when the topmost man is like that. Basically that old sect leader doesn't give a shit about anything, as long as nobody is attacking the sect, for any reason, not even in self-defense. It's practically an order for the lower levels to do crimes as much as they want. It's pretty funny such a sect isn't called a dark sect but is supposedly the protector of the empire. Must be quite a mafia empire.
