Description：The emperor suffers from a strange disease, and Lu Xiaofeng (played by Raymond Lam) is ordered to investigate. As a result, the ancient Jinpeng Dynasty, which has been forgotten for many years, has surfaced, and it also involves the orphan princess Shangguan Fengdan (played by Lan Xi). It turns out that the emperor was framed and poisoned, and the person who can detoxify is hiding in the Jinpeng Dynasty. Finding out who is behind the scenes has become Lu Xiaofeng's top priority. The court was in panic and undercurrents were surging. Lu Xiaofeng's investigation has fallen into a bottleneck and is difficult to move forward. In the most difficult time, Lu Xiaofeng met the famous doctor Hua Manlou (played by Zhang Xiaolong) and the sword master Ximen Chuixue, and a deep friendship was formed between the three. At the same time, a girl named Ashin (played by Zhang Meng) has been silently supporting and helping Hua Manlou. Even though she knew that Hua Manlou loved Princess Fengdan, she still devoted herself without hesitation.
