In order to raise money to treat my sick mother, I signed a life-and-death contract and became a test subject for a space-time machine that was still in the experimental stage. The machine broke down and my soul was drawn into an imaginary era - the Yan Dynasty. Yun Yan'er is my identity here. She was made fun of by the whole city for being fat. With the help of Aunt Qin, I successfully lost weight and became a stunning beauty, and entered the palace draft. After experiencing all kinds of harem fights and vicissitudes of events, I transformed from an ignorant girl to the Queen of the Yan Kingdom step by step.
