Zhang Yimeng, an ordinary modern girl, always has an extraordinary dream.In the dream, she was Princess Yuanjun of the ancient Xixi Kingdom. She was forced into marriage, and her life was hanging by a thread.At a critical moment, General Ye Zhu, the general of the Beichi Army, appeared and gave her a glimmer of hope.But the good times didn't last long. When her life was at stake, she was kidnapped. In order not to implicate Ye Zhu, she chose to jump into the river.Ye Zhu followed closely, but failed to grab her hand.Yuanjun struggled in the water, feeling like he was about to lose consciousness.Suddenly, she woke up from her dream.

This dream reoccurred repeatedly, and Zhang Yimeng began to believe that she was Princess Yuanjun.Her thoughts worried her parents, who thought she was mentally ill and took her to the hospital for treatment.However, Yuanjun firmly believed that she was not sick. After coming out of the hospital, she still stubbornly believed that she was an ancient princess.

One day, while walking by the river, she looked at the reflection in the water and remembered the scene with Ye Zhu again.In a daze, she leaned forward and accidentally fell into the river.When she woke up again, she found herself in a strange environment, with the maids beside her wearing ancient costumes.She finally realized that she had traveled to the ancient Xi country and became the real Princess Yuanjun.

However, what she didn't expect was that after time traveling, she was also a maid.When she was confused, the housekeeper came in with a group of people, holding whips, ready to teach her a lesson.
