The ruler of the Li Dynasty was dissolute and extravagant, causing the people to live in dire straits and mourning all over the land. Gu Changsheng revolted and ordered millions of rebels to overthrow the Li Dynasty's rule and save the people from the fire. However, when the world stabilized, the new emperor was not Gu Changsheng, nor any member of the Gu family, but Qi Shaohua, the eldest son of the Qi family who had provided huge financial support to the uprising. In the blink of an eye, the Qi family dynasty has been in power for more than a hundred years. Qi Shaohua has passed away long ago. His son Qi Liancheng has also fallen ill due to years of hard work in government affairs. It is urgent to elect a new emperor. Qi Liancheng's elder brother Qi Lianbi took advantage of this opportunity to usurp the throne and attacked the current prince Qi Shengyan several times. Fortunately, Qi Shengyan was helped by Gu Yanchao, Gu's eldest son, to escape from Qi Lianbi's clutches and successfully stabilized the situation. In order to expose Qi Lianbi's conspiracy, "Gu Yanchao" and Qi Shengyan secretly left the capital, hoping to find evidence that Qi Lianbi had betrayed the country earlier. As a result, the two met Nie Yinchen, the most benevolent doctor in the world, and He Yunke, the daughter of the master swordsmith He Jiao. After many hardships, they finally obtained the certificate. The journey was full of dangers, and Qi Shengyan and others gradually discovered that the eldest son of Gu was actually Gu Yanchao's twin sister Gu Yanxi. However, what was unexpected was that the real Gu Yanchao actually turned against Qi Lianbi. The Qi dynasty is in danger. At this time of imminent storm, can Qi Shengyan quell the chaos and successfully ascend the throne? Facing her brother's betrayal, what choice will Gu Yanxi make? Will Nie Yinchen and He Yunke help them?
