My Sister-In-Law Sued Me for Disguising Myself as a Man and Becoming a General.

I control an army of 300,000 men to save the country from danger and repel the invasion of the northern enemy. At the celebration banquet, my concubine, who was jealous of me, exposed me in public as a man disguised as a man and said that I had committed the crime of deceiving the emperor. I looked at my shivering sister and looked at the emperor without any fear. Sister, my 300,000-strong army is not just for display.
