Synopsis：In the early years of Tiancheng, Lin Jian pacified the land with the help of the "Cai Xi Shi" Hong Yi, who was then appointed as the National Preceptor and established the Yunji Society to train more "Cai Xi Shi". Years later, Lin Jian fell gravely ill, and the Second Prince Lin Guang conspired with Minister Lin Su to usurp the throne. To eliminate the troublesome Hong Yi, Lin Su successfully bribed Hong Yi's disciple Zhou Fang and learned the location of the "Yun Ji Lu", the book that records the art of Cai Xi. In Longyou Town, a young man named Xiang Bai aspires to become a Cai Xi Shi. He has lived with Cai Ying and Zhong Ma since childhood. Zhou Fang comes to Longyou Town in search of the "Yun Ji Lu" but finds nothing; instead, he accidentally discovers Cai Ying, who bears a striking resemblance to Hong Yi, and decides to kidnap her. The hidden master Zhong Ma fights Zhou Fang to the death and, before dying, tells Xiang Bai to seek out Hong Yi. To rescue Cai Ying, Xiang Bai goes to the Yunji Society, where he unexpectedly encounters Gongshu Pan, the "descendant of Luban". Meanwhile, Lin Su and his allies are plotting a grand conspiracy to use Cai Ying as a stand-in for Hong Yi.
