Chen San finally understood Ye Qingzhen's real plan; in fact, Ye Qingzhen had been employing the Empty Fort Strategy from the start.
From the beginning, Ye Qingzhen appeared confident, telling Wang Tian'an about his plan. This put Wang Tian'an on edge, making him wary of Ye Qingzhen all the time. Later, Ye Qingzhen orchestrated an attack on Wang Tian'an's territory and stole the food for the Heart-devouring Bug, pushing Wang Tian'an nearly to the brink of collapse. He began to suspect that Ye Qingzhen indeed had a winning strategy. The calmer Ye Qingzhen appeared, the more frightened Wang Tian'an became, considering he had been scared by Ye Qingzhen several times before and was now in a state of high alert.
