The trio immediately fell in love with dog fight gambling when they saw the arena in Shanghai. Even Yuan Chuling no longer wanted to manage his gym and just spent his time wandering about to get some good dogs and then made a big profit out of them. He never found such a good chance to make money before, so he brought Yue Kai and Hu Qingsong to the western region to get some excellent dogs.
Dog fight gambling was very strictly regulated in Shanghai, and they could only participate a few times there, which earned them some money. Yet, it didn't satisfy them, so the trio and one dog straightly headed to Jingmen Island after hearing that many people were involved in dog fight gambling with large stakes.
