The age old Xianxia conundrum: If you've been doing everything you can to kill someone what threat do you have left when they try to kill you? You done already got your family involved. There's nothing left to give yourself a way out.
I'd like to see some smart villains. Play it cool like things are settled and then come back for revenge later when you think it's easy. That way the guy won't kill you first opportunity he gets.
