In Luoyang Paper Expensive, Yu Wenpei accepted Liu when she assassinated Queen Dongchuan. Why would she do that?

Because she still loves Liu Shirang, she can't get back together with Liu Shirang because of her helplessness. The assassination of King Dongchuan was her last task. This task is very dangerous. Before accepting the task, she begged her superiors to allow her to do this last task. If this mission is successful, let her leave, so if the assassination is successful, then she will be free and she can continue to be with Liu Shiro. Yuwen Peipei was originally named He Chun. She and Liu Yuan were lovers, but because of the change of the Liu family, Liu moved away from home and was forced to separate from her. Yu Wenpei was Liu's maid. After her master Liu left, she became helpless, with neither money nor care, and suffered all kinds of bullying.

She was reluctant to join Chunqiu Road. Desperate and poor, she joined the villain Chunqiu Road. After years of cultivation by the villain Chundaoshu, she was arranged to be the top dancer in Hongguangfang. Many of her tasks are deliberately close to powerful people, and her position makes it impossible for her to stay with her former lover Liu. Two people used to love each other so much, only because Liu Jiating's misfortune caused them to be separated for more than ten years. When they met again, things had changed. In those days, the gentle and lovely little handmaid had already become the number one card known to all gods, and was a powerful chess piece in the hands of the villains secretly. Her identity itself is very sensitive and dangerous, so she can't get back together with Liu, so she can only break up constantly.

The task of a narrow escape is to meet Liu again after ten years' absence. Both of them are full of memories and regrets, but they have no choice. She thought they would never be together again. As a result, something great happened to God at this time. Gong Yan, the deputy leader of Chunqiu Road, her superior, found her and asked her to assassinate His Royal Highness King Dongchuan as a weak woman. Yu Wenpei, who has such a disparity in identity and no martial arts, is simply a narrow escape in the face of such an arduous task. Even if she succeeds, she will become a wanted man. She can't stay in God at all, so she can only escape and live in seclusion.

She wants to start a new life. She knew that Liu Shirang was still affectionate and righteous to herself. Although the probability of her assassination is very small, she is still willing to take risks for freedom and to fly away with Liu Shiro. Therefore, after her successful assassination of King Dongchuan, she was free and agreed to Liu Shirang's request to be together. She accepted Liu Shirang's love, and with good expectations for her future life, she wanted to elope with Liu Shirang and leave God.
