In her previous life, Jiang Wanyin was obsessively devoted to Xiao Jing, the empress’s legitimate son. She willingly became a blade in the empress’s hand and a pawn in the Jiang family’s pursuit of power, clearing every obstacle in Xiao Jing’s path to the throne. In the second year after she helped Xiao Jing ascend the throne and became empress, he had her beheaded in public. Her family abandoned her and blamed every crime on her. Only then did she realize that Xiao Jing had loved all along the daughter of the Shen family she had once helped destroy: Shen Qinghe, the third young lady of the Shen family. Because of her, the Shen family fell and Shen Qinghe was killed. Xiao Jing had always hated her, and the empress too. He had only pretended to love her, when in truth he hated her and wished she would die at any moment.
After her death, she found herself in the new century, where she became a traditional Chinese medicine doctor. Following an accident, she returned to the age of fifteen in her previous life. This time, she would never again beg for an illusory love or become a villain. This time, she would simply be herself. To make amends for her past mistakes, she saves the Shen family, treats an epidemic, and takes down corrupt officials. Along the way, she meets Shen Zhiyu, the Shen family’s prime minister. The two repeatedly join forces, working together with remarkable understanding.
