Qian Ziying, in modern times, was a child abandoned by his parents. He fell into a coma due to the design of his adoptive parents. However, he inadvertently traveled through time and space and came to Qingxi. He met two men he loved, Qingtianyao and Qingtianyan, and became Yan. However, the princess witnessed Yan's betrayal the day before her wedding, so she left Yan, only to find that it was all a trap designed by Yao. In the end, she saw the man she loved most die beside her, and she was also seriously injured.
After waking up, Qian Ziying changed her name to Qian Ying and dressed as a man. In order to protect Yan's soldiers, she left the capital and came to Lincheng, where she opened the world's number one escort agency, Qian Yan Escort Agency. She also got acquainted with the bodyguard Yijian who had a blood feud, the leader of the tomb robbers Wei Ang, and his younger brother Wei Hong, as well as the mainstream of the demon sect Yun Yin, Prince Xiaoyao Qingtianyi, and the general Ren Genghuai.
And had more or less love-hate relationships with them, but in the end he had to marry the current emperor Qing Tianqiu, Yan's biological brother, for the sake of his friends.
Qian Ziying used her modern knowledge to create a world of her own in ancient times, and changed Qing's social habits that had always been male-oriented. She created a new chapter in the history of Qingtian, known as Queen Qingtian in history.
