Defeat Guan Hai and Liu Pi in the east land so Sun Jian's army can advance. After helping Liu Bei in the south with Gao Sheng, Zhang Liang will summon a rainstorm. Huangfu Song will pass through the castle only to be ambush by He Yi. Go ahead and bail him out, then wait for Yan Zheng to ambush him when Huangfu Song arrives outside of the castle at the northeast. Defeat Yan Zheng and head for Zhang Liang to end his attack on the Han forces. Completing this level will prevent him appearing in the last battle, but only if he is defeated before he can retreat, which happens once every Yellow Turban officer on the map, including Zhang Liang's sub-officer Han Xian, are defeated, though he will stay and fight if already engaged by Han forces.
