Luo Qing Chuan (Yang Mi), a history fanatic with full of curiosity, went to search for a missing painting and found herself next to a weird looking tree. Then she is suddenly transported back to time during Emperor Kang Xi's reign of Qing dynasty.
She becomes entangled in a love triangle between Yin Si (Feng Shao Feng), the eighth prince, and Yin Zhen, the fourth prince and future Emperor Yong Zheng. According to history, the 8th prince had a very tragic life due to the 4th prince's doing. Who will Qing Chuan choose at the end? How will she get back at modern time?
The story between the leads reminds me of a historical version of F4's Tsukasa x Makino x Rui relationship. Especially Yin Si teasing Qing Chuan every chance he could get only to fall in love with her.
