CHINESE TITLE — 且试天下 (aka Qie Shi Tian Xia)

PLOT

The supremely elegant Hei Feng Xi (played by Yang Yang) and the peerlessly radiant Bai Feng Xi (played by Zhao Lu Si) meet and spar for ten years in the martial world, earning the joint title of “White Feng and Black Xi” among the warriors.

It is only when the imperial court undergoes turbulent changes that they discover each other’s alternate identities — Hei Feng Xi is in fact Feng Lan Xi, the second prince of Yongzhou, while Bai Feng Xi is actually Feng Xi Yun, the princess of Qingzhou.

After securing his position as the heir to the throne of Yongzhou, Feng Lan Xi accompanies Feng Xi Yun back to Qingzhou to witness her ascension as its queen and stands by her side to confront the joint invasion of Qingzhou by the allied forces of Youzhou and Yizhou.

In the end, the two join forces to eliminate Yu Wuyuan, who is plunging the world into chaos for personal gain.
