Sangyu: ox and horse → prince → emperor
"Copywriting"
Sang Yu worked hard to save her seriously ill mother, and was selected by the system during an overtime shift. The system promised her that as long as she went to ancient times with herself, her mother could be cured, and Sang Yu readily agreed.
Sang Yu dressed up as a "prince" disguised as a man. On the way to complete the task, she met Xie Yan, and the two became friends because of their similar interests.
However, they met during the morning court. Sang Yu learned that Xie Yan was the regent, and the two decided to have a talk after the morning court.
Leniency for confession.
Xie Yan confessed that he was also a time traveler, and Sang Yu had a look on his face as if a fellow countryman was crying when he saw a fellow countryman. Sang Yu also revealed her plan to usurp the throne, and Xie Yan expressed his intention to help her.
—The two began their plan to usurp the throne—
They decided to let Sang Yu become the prince first, so Sang Yu began to visit and ask people frequently, and submitted tax reduction packages to benefit the people. And Xie Yan was secretly investigating the prince.
Finally, the prince Sang Mingli couldn't bear the twists and turns in the court and decided to escape with his beloved.
The emperor was furious, and seeing that Sang Yu had won the hearts of the people before, he made Sang Yu the crown prince in anger.
The villain of the third prince, Qi Sang Yu, became the crown prince so easily. In order to fight for the throne, he secretly sent someone to investigate and discovered Sang Yu's true gender. He sent Sang Yu to jail on the grounds that women could not ascend the throne.
Xie Yan was shocked, and united with the people who had been favored by Sang Yu to rise up to resist, and sent people to secretly investigate the villain. All the evidence of the third prince's crimes were made public, which aroused public indignation, and the third prince was overthrown. With the support of the people, Sang Yu was released from prison and became a prince. The emperor abolished the law that women could not be princes.
…
After the emperor died of illness, Sang Yu ascended the throne. Sang Yu, who had been in love with Xie Yan for a long time, named Xie Yan queen.
The system also fulfilled its original promise, and the two got romantically married in ancient times.
