What is going to happen to our MC in the future?
A. She will become a fine man and find a good wife.
B. She will transform into Mulan and win this war for the Xia Kingdom.
C. She will channel her newfound confidence into her feminine arts and prove to the general that she is a girl by embroidering.
D. She will become a fine man and make the general fall head over heals for her. The general will propose, thinking that he somehow turned homosexual, and they will become the first man and woman to become a gay married couple.
I still think the Xia Kingdom has this war in the bag, so I'm thinking that B seems the most likely!
