Quite a fun one, not too hard, until Zhou Yu wipes the floor with you like always.
Difficulty: Expert
Stage: Encounter at Jiang Ling
Restrictions: No Bodyguards
Requirements: Meet Niu Jin after his morale reaches 8 stars (Goes up for every 15 KO's you get) have at least 250 Ko's. And defeat all 4 enemy officers.
Tips: Fairly simple, Niu Jin can survive for ages without you meeting him providing you are constantly defeating enemy troops. It's a good idea to seal the gates either side too to prevent troops attacking Niu Jin when he needs to retreat. Once you've defeated Han Dang and Gan Ning you will need to babysit him otherwise Zhou Tai and Zhou Yu will relentlessly attack him,
