In Bixi Country, the Tang family is famous, but Tang Wanyue's fate is full of twists and turns. When he was young, he accidentally fell off a cliff and was poisoned by witchcraft. His appearance became ugly. He could only briefly regain his true appearance on the first and fifteenth full moon nights of every month, so he had to hide under a hat on weekdays. Legend has it that only the magical medicine "Yinshuanglu" can break this curse.
At the same time, Xiao Yihan, the eldest son of Pufang Kingdom, was suffering from a serious illness. Only the Tang family's "Xianweicao" could save his life. A marriage of interests related to the fate of the two people began. Tang Wanyue unexpectedly became the crown prince's concubine and stepped into the crown prince's palace of Pufang Kingdom.
However, fate plays tricks on people. Mu Jinxuan, the eldest son of Xueji Kingdom, and Tang Wanyue were childhood sweethearts. After they reunited, their old love rekindled and their emotional entanglement intensified. The intervention of Princess Chiyan, the conspiracy of Lord Chiyan to go to Tantai Qianye, the jade pendant of the late emperor in Mu Jinxuan's hand, and the calculations of Xiao Yihan's former lover Yue Lin'er made the situation more complicated and undercurrent.
What is even more disturbing is that the "Hantan Snake" organization has quietly emerged, with hidden stakes all over the country, pushing this contest of power and emotion into the abyss. Xiao Yihan and Tang Wanyue, a couple who initially joined together due to interests, gradually fell in love through battles of wits and courage, supported each other, and faced crises together. They used courage as a shield and wisdom as a sword to uncover layers of conspiracies.
In the end, they resolved many crises, worked hand in hand in troubled times, unified the world, and wrote a legend that has been passed down through the ages.
