The heroine Jiang Wan traveled through time and became the foolish and abandoned daughter of the prime minister's palace. She was designed by the family to marry the prince Xiao Jue who was poisoned, had disabled legs, and had a violent temper. Everyone was waiting to see when she would be tortured to death. However, Jiang Wan relied on modern medical and poison knowledge to not only cure Xiao Jue's strange poison, but also used thunderous methods to punish all those who had bullied her, both inside and outside the palace, and in the court. She used the "Shadowless Needle" to save people in an instant, and the "Thousand-Mind Guide" to kill people invisible. She counterattacked from an abandoned daughter who was ridiculed to become a "ghost-hand poison doctor" that everyone respected. From the initial temptation and use of the male protagonist Xiao Jue to his deep love and exclusive favor, the two of them worked together to uncover the mystery of their life experience, the palace conspiracy and the disputes between the two countries. In the end, Xiao Jue won the throne for her and promised her that they would rule the country together for the rest of their lives.
