Enchanted by Your Beauty

Miao girl Su Yan was born into a family of sorcerers and healers in the Southern Frontier. Her father was appreciated for his skill in using Gu (poisonous insects) to heal the wounded and was appointed as a royal physician. For generations, the Yun family had implanted their secret technique—the Undying Gu—in their bodies to provide an extra layer of protection for their members. The Undying Gu could bring the dead back to life, but it could only be used once in a lifetime, either on oneself or to heal others, and it was rarely given away. Three years ago, the Third Prince, Yu Jiuyuan, was ordered to quell a rebellion in the Southern Frontier but was assassinated. Su Yan, who was away, discovered him. She had long admired the renowned Third Prince, and upon seeing him dead, she didn't hesitate to use the Undying Gu within her to revive him. Yu Jiuyuan was severely injured and temporarily blinded upon waking. Su Yan, coincidentally, was also unable to speak due to the backlash from the Undying Gu. During Yu Jiuyuan's recovery, Su Yan silently cared for him, allowing..." Deeply moved, Yu Jiuyuan, though unable to see his benefactor's face, had already decided in his heart that this woman was the love of his life. Before departing, Yu Jiuyuan gave Su Yan his personal jade pendant, promising to personally return to the Southern Frontier to bring her back to his manor. During the chaos of war in the Southern Frontier, Su Yan lost her jade pendant while fleeing. After waiting anxiously for Yu Jiuyuan's return, she desperately urged her father to petition the Emperor for a marriage decree, and finally, her wish was fulfilled as she married into the royal family. However, on their wedding night, the groom, Yu Jiuyuan, led another woman, Chu Yunrou, to Su Yan, telling her that this woman was the very person he had been searching for to save his life. At that moment, Su Yan noticed the jade pendant Yu Jiuyuan had given her years ago hanging from Chu Yunrou's waist. It turned out that Chu Yunrou had found the jade pendant she had lost, and thus, Chu Yunrou had conveniently taken over the identity of her savior…
