The poor girl is specially favored by the goddess of fate Manshen (Chen Hong). When she grows up, she becomes the pampered princess Qingcheng (Cecilia Cheung). However, she is also cursed by the fate spell that "she will never get true love unless time goes back and people are resurrected from the dead". In the love struggle with Beigong Jue Wuhuan (Nicholas Tse), General Guangming (Hiroyuki Sanada) and others, Qingcheng is used as a bargaining chip by the other party again and again, and the spell works. However, the humble slave Kunlun Nu (Jang Dong-gun) truly loves Qingcheng. He hopes to use his running at a speed close to the speed of light to break the chain of fate imposed on Qingcheng, so that she can return to the starting point of her life and regain the right to choose.
