Crossing the Great Q

Yang Lin picked out ten of the tallest men: "You ten, as shield bearers, hold your large shields in front. Your duty is to protect the spearmen and crossbowmen behind you!","Tao Ge, later you divide the manpower to guard the front gate, back gate, and all around the walls of the courtyard. Don't let any bandits escape!","Uh... there are over fifty of them, they killed the guard at the gate and have already gotten into the courtyard!"。
