Crossing the Great Q

"You twenty men, as pikemen, wait until after you charge in. When you hear my order, when I shout 'thrust', then thrust your pikes forward; when I shout 'retreat', then pull back your pikes!",Yang Lin looked at the veterans of the guard and said, "I won't need to explain. Each of you bring thirty crossbow arrows, your mission is to shoot at the mark!","You personally lead a hundred men in, and provide cover for us."。
