Not much of a fucking clan head if he can't tell Lin Lang is a shitter and doesn't even deserve a place in the clan but hey Wuxia stories are always flawed like this lol.
@Jesotku
it's you who have a mentality of "Wuxia stories" ...
What should he have done? what's the best for the clan?
what he did is the best thing possible, with luck the other will evolve mentally and there will be two new powerful people in the clan
but it is obvious that the other will remain a shitty person and of course it will be "wuxia" style, but the leader had a normal attitude, the most beneficial for the clan, but if the apple is completely rotten it will not be not his fault
@Jesotku The clan head has seen him for all of 2 minutes, after a testosterone filled fight. He can't judge his attitude based on that, cause anyone would be acting like a dick at that point.
