Married to the General

The princess was ordered to marry the disabled general Chu Pingyun. Who knew that the goods were wrong on the night of the wedding. The princess is not a princess, but Li Jiu, the good for nothing prince?!
Chu Pingyun: ...Can I return you back?
Since you can't return the goods, you can only use your lifelong acting skills to play a pair of beloved husbands, to tear up your political enemies, break the puzzle, and fight on the battlefield- hey, how does it seem to come true?
