Was prepared at Ma Ning's parent's home before she left to her husband's home.
Achieve 80 KO Count in under 5:01 minutes. It is not necessary to defeat Yue Jin and Li Dian. This on Hard
Defeat Li Dian and Yue Jin before they re-gather their troops. Defeat either Cao Xiu or Zhang Liao after they appear. Achieve 140 KO Count. This on Expert mode. Li Dian and Yue Jin will start to re-gather their troops approximately 2 minutes into the stage. If you defeat them before 2 minutes, a Precious Item Report will appear. Try to accumulate as much KO Count as possible during the period of time before Cao Xiu and Zhang Liao appears. Defeating one of the latter 2 enemy generals will give you an "S" rank. I recommend defeating Cao Xiu, because he's a lot easier to defeat than Zhang Liao. Just a mention, to clear the stage you need to defeat the correct enemy entry point captain to find the route of retreat. The correct one is said to be random, but of the 8 times I played, the exit had always been the bottom entry point. So maybe that is the one?
