Hundreds of years ago, a Yao king lost his beloved princess. In order to bring her beloved back to life, he spent his whole life practicing elixir but failed. He was so grief-stricken and angry that he cried blood all day long and went crazy. When he was desperate, he sacrificed his soul and jumped into the alchemy furnace with his flesh and blood body, and finally refined the ancestor of all elixirs - "Tai Chi Xuan Dan". But who would have thought that King Yao's crazy behavior failed to save his beloved, but brought endless disasters to his descendants.
Lan Qingyang is the last king of Yao Kingdom. He cultivated literary and military strategies and worked hard to govern. In order to preserve the Yao Kingdom and protect the royal bloodline, he issued a decree prohibiting the use of living people to make elixirs. He single-handedly founded the Blue Flame Alliance and trained countless spies to travel to various countries, but he failed to change the outcome of the country's subjugation. The Seven Years' War completely brought down this small country, and Lan Qingyang eventually died for his country. His queen, Princess Yunhe of Emperor Xuande, committed suicide beside him.
However, although Lan Qingyang died, the Blue Flame Alliance was not destroyed. The most secret force of the Yao Kingdom is regrouped in a new pair of hands. In the capital city of the empire, a teacher from the royal palace was about to get married to the daughter of the Shangshufu, but on the eve of the wedding, he entered the palace and became a eunuch. The bride was so ashamed and angry that she immediately committed suicide by hanging from the beam.
Immediately afterwards, the originally powerful Central Plains dynasty became ill-fated and precarious amidst curses and conspiracies. Emperor Xuande died of poison, and the emperor who had just ascended the throne inexplicably embarked on the road of no return by conquering the country himself. As for the Pingnan Monument, it is privately called the "Book of Life and Death" in the capital - the heroes who contributed to the destruction of the country on this monument died mysteriously and tragically one after another. There is only one last name left on the monument: Gu Zongkai. Gu Lian must find out all this - is it the return of King Yao's curse, or is there someone using the name of the curse to conspire to cause chaos in the country?
Intent: A historical machinations drama based on "Elixirs of Medicine", exploring the eternal propositions of loyalty and righteousness, crime and punishment, protection and sacrifice.
