Stage: The Battle at You Ting (Original Mode) - Wu Forces
Defeat Cao Xiu. Weapon Box appears next to Cao Xiu's starting location.
Other notes:
A very straightforward weapon to obtain. You can play the stage as intended and defeat the two fort commanders, Zhang Pu and Zhang He, or go straight for Cao Xiu if you wish. Note that you will have to defeat Zhou Fang if you defeat Cao Xiu before surrounding him, as he will not defect, unless you wait for 10 minutes into the battle for Sima Yi to detect the double agent.
As usual for this battle, Zhen Ji will head straight for your location, so it helps to take her out before approaching Cao Xiu, as you may find yourself with three officers in one place, as Man Chong, who is attached to Cao Xiu's forces, sometimes like to hang around his boss.
