Gusu Yuyao is the beloved daughter of King Gusu and the eldest princess. She was suffering from cold poison when she was young, so she traveled around with her master in search of medicine to cure her illness.
By chance, she rescued Prince Ning, who was bruised and poisoned, and the two fell in love with each other. She thought she had found a husband with whom she could share the same love and stay together for the rest of her life.
Unexpectedly, King Ning was so ambitious that he had three wives and four concubines in order to seize the throne, and even tortured his beloved concubine.
Once the heart dies, love and hate become empty.
She left decisively and returned to Suzhou, eventually becoming a generation of empress and writing the legend of ruling the world.
