How do you get Zhuge Liangs level 11 weapon in Dynasty Warriors 4 Extreme Legends?

Defeat Yue Ying 6 times, each time very quickly thus receiving a "(Excellent Victory)" comment.

Defeat Ma Dai.

Defeat Fa Zheng.

Defeat Yan Yan.

I suggest saving in between each Excellent Victories.

You should receive a Precious Item Report together with the weapon learned

message, not guide related, but I have to say, this is a fun stage.

Do this on Expert Mode
