Description：Qianlong (played by Wu Mengda) was assassinated by the assassin Xu Lian (played by Shu Chang) on the way to the lotus pond. In the fierce fight, Qianlong lost the extremely important Qiankun fan. Chen Wenjie (played by Dingdang) is a genius child famous in the capital. He was already the top scholar granted by the emperor at the age of nine. Together with his adoptive father Chen Qingyun (played by Wu Mengda) and his good friend Xinyuan Little Monk (played by Lu Yihan), a group of three people embarked on a journey to find the Qiankun fan and hunt down the assassin. On the way, the three of them met the unruly and willful Princess Ten (played by Chen Min), and Xu Lian also disguised herself and hid her identity, lurking beside the three of them. They had constant troubles and twists and turns along the way, but Chen Wenjie resolved them one by one with his wisdom. In the end, Chen Wenjie discovered that He Kun (played by Zeng Zhiwei), the confidant minister of Qianlong who he firmly believed in, was the one who was responsible for everything.
