Wang Zhaodi's soul passed away in a car accident, and she became Ning Jiao'er, the legitimate daughter of the general of the fictional dynasty. She was also bound by the system to protect the heroine Su Mingtang - to prevent her from repeating the mistake of marrying the ruthless prince Bi Xiuyu in her previous life, and eventually dying of depression.
In order to protect Su Mingtang, Ning Jiaoer transformed into a "little CP buster" and tried every means to prevent the relationship between Su Mingtang and Bi Xiuyu from warming up. During this frantic "rescue" journey, she accidentally met the fourth prince Bi Bojie - a man who seemed to be playing with the world, suave, but extremely sincere.
The old emperor is critically ill. Bi Xiuyu is not a good man, but he is an able ruler. Su Mingtang and Ning Jiaoer were both pushed to the point where they had to choose a princely marriage.
Ning Jiaoer, who knew Bi Xiuyu's true nature well, made the most painful decision in order to completely cut off the chain leading Su Mingtang to tragedy: she married Bi Xiuyu instead of Su Mingtang. He personally sent himself into the deep palace cage, and also personally pushed away the love of his life, Bi Bojie.
She didn't know that as the leader of the Poison Sect, Bi Bojie's body was originally the most poisonous in the world and had long been out of balance due to various reasons.
After learning of her choice, he finally died with hatred.
Ning Jiaoer became the Queen of Jingguo, which allowed Su Mingtang to escape from the world and live happily. But the last message sent from the system was that the original world had not changed, and Su Mingtang ended up depressed. She sacrificed her life's happiness and love, but what she got in exchange was an empty sacrifice.
