After another ten stances or so, the weaknesses in Lu You Jiao’s [Dog Beating Stick Technique] began to show itself. Yang Guo saw every stance clearly and couldn’t stop himself from creasing his brows. Luckily the [Dog Beating Stick Technique]’s name is famous, and as soon as it was used, Huo Dou was struck in the lower leg, Huo Dou was worried and didn’t dare to get too close, otherwise Lu You Jiao would have lost long ago. Huang Rong saw that something was wrong and was about to call out and tell Lu You Jiao to come back when Lu You Jiao suddenly used a stance of [Hitting the Dog’s Back from the Side], the bamboo stick flashed across and struck Huo Dou’s left cheek. But this stance was too heavy, the lightness of the skill was lost, Huo Dou suddenly stretched out his hand and held the bamboo stick in his hand, he had no more worries and suddenly threw out a palm that struck Lu You Jiao in the chest and then followed it by a sweep, a ‘ka la’ sound was heard as Lu You Jiao’s leg was broken, a pool of blood was spat out as he fell forwards. Two seven band members dashed forward to support him. When everyone saw how ruthless Huo Dou was, they were extremely angry and they all shouted out and cursed.
