The Emperor and I Switched Bodies

[I've passed my thesis defense and am writing now. Two chapters tomorrow.] The young prime minister of the Kingdom of Liujin is known for her iron-fisted rule. The emperor promoted her, only for her to turn around and seize his power. Ye Yun is exceptionally talented and beautiful, the ideal match in the eyes of noblewomen and the perfect son-in-law in the eyes of the ministers. In short, she is at the height of her power, and has bullied the emperor to her heart's content. Then she and the emperor switched bodies. They stared into each other's eyes. Cheng Sheng: "Prime Minister, you're a woman?" Ye Yun: "Your uncle is plotting rebellion. Did you know?" Cheng Sheng: "I know, I know! Could you teach me how to use this chest binder first? I'm being squeezed to death." After a punch, Cheng Sheng clutched his stomach. "Are you always this rough with your own body?" Ye Yun: "Let's talk business." Cheng Sheng: "Then teach me statecraft." Later, Ye Yun not only trained an excellent emperor, but also won the emperor's heart. Cheng Sheng said cheerfully, "Prime Minister, you've been promoted. You're now the empress of the Kingdom of Liujin."
