Su Xiao, an emergency doctor, was accused of being the reincarnation of Queen Jishi of Dayan. She didn't believe it at first, but after she fainted, she traveled through time and became the critically ill legitimate daughter of the Shangshu Mansion. She was diagnosed with tuberculosis based on her knowledge of Western medicine and saved herself. However, she was offered a marriage to the powerful fake eunuch Cheng Ye. From temptation to alliance, the two teamed up to torture the scum and outwit the palace to unlock the truth about time travel. In the end, the two resigned and returned to the south of the Yangtze River, opened a medical clinic to help the world, passed down the fire of Western medicine, and stayed together as a miracle doctor couple who gave birth to a child and became the envy of everyone.
