For those who read Roman of the Three Kingdoms of Chinese classic literature, the Eight Elements Battle Formation can arouse maximal curiosity. According to the book, general Lu Xun of the Wu Kingdom chased after the defeated Shu army until the Fengjie County, when he stopped feeling something dangerous was ahead. But the sentinel returned reporting there was nothing but piles of stones and rocks. Lu Xun laughed and marched ahead all the way to the stone formation. All of the sudden the stones and rocks began to move like approaching swords up and down, encircling the troops. At that moment, an old man appeared and said he could lead the troops out of the formation. When they finally got out of the formation, the old man told Lu that Zhuge Liang had already foreseen that a general of Wu Kingdom would be trapped in the formation. Lu Xun then realized the stratagem and the foresight of Zhuge Liang were unsurpassable.
