As the topic says does ryo actually kill dou niu? i don't know if this has been discussed i've checked the forum from time to time but only just signed up!
also don't know if it's been discussed but how many people will ryo kill to get his 'revenge' , i mean he obviously kills chai if he throws or beats him off the boat in chapter 2, so there is potentially 2 already and if he wants to fight lan di he will surely take the 'evil path' Xiuying mentions as he will have to be a high ranking gang member of a various gang to get to him as he won't just bump in to him in a tomato convenience store lol
sorry if this has been talked through a million times!
