As Buck finished shouting, a reply from either Zhou himself or one of his men rang back in the form of a shotgun blast that tore a nice sized hole in the shelf above him. "Shit." He though looking down again at his wound then at the door. "Gotta make a choice now." With that Buck reloaded his Winchester. He quickly stood up and charged into the room, gun blazing. He hit the man that had fired on him and sent him falling to the floor. Buck glanced around. Zhou was no where in sight. There were piles of laundry bags everywhere. Buck smiled as he approached them. He was about to shout out to Zhou when he heard a match strike behind him. He spun, gun at the ready, to see what had caused that sound.

He turned just in time to see the man he had shot and not killed lighting the fuse on a stick of dynamite. The man smiled at Buck and threw the dynamite at him. Buck ran faster than he'd ever run before. Out of the back room and out of the store. There was one thing that Buck never messed with, and that was explosives. He stood outside the store waiting for the explosion, when a few of Zhou's men, attracted by the shoot out, were running towards him. Buck cursed slightly under his breath as they began to open fire on him. He turned and tore through the town until he reached where he had his horse stabled at. One of Zhou's men persuaded him, while the others went to check on their leader. 

Buck barley managed to get out of the stables before the man opened fire again, winging him in the arm. Buck quickly drew his Colt and shot the man dead as he rode out of town. He spurred his horse forward knowing he needed to see a doctor. If he stayed there surely one of Zhou's men would have put a bullet in his head eventually. Buck turned around and saw he wasn't being chased and slowed his horse to a gallop as he cradled his shot arm. It, again, had only grazed him, but it was bleeding profusely. The whole time Buck waited to hear an explosion that never came. Which he took to mean that Zhou was still alive.
