In the autumn of the thirteenth year of Yong'an, King Sangce of Zhenbei went to the border. His aunt Ye Luolan took the opportunity to join forces with outsiders and kidnapped seven-year-old Sang Yuzhi. Sang Yuzhi was extremely intelligent and knew that his mother, Shen Qingwan, did not die of illness, but was killed by Ye Luolan - just because her mother blocked Ye Luolan's path to becoming a mistress. Now, Ye Luolan was afraid that Sang Yuzhi would interfere with her daughter Sang Weiyu's position as the eldest lady, so she cruelly pushed her into the river.
Fortunately, he was rescued by the reclusive master Xuan Jizi. Sang Yuzhi kept in mind the blood feud and devoted himself to training for ten years, acquiring superb medical and poison skills and martial arts strategies. After becoming an adult, she returned to the capital under the pseudonym "Su Zhi". With her medical skills, she became famous in Jing'antang and was called "Miracle Doctor Su".
By chance, she diagnosed Xiao Jingyu, the powerful regent, and discovered that his "wind-cold" was actually the chronic poison "Hanxiang Powder", and successfully prepared the medicine to detoxify it. Xiao Qingyu was curious and appreciative of this mysterious and intelligent woman, and allowed her to stay in the palace temporarily.
Sang Yuzhi used his strength to collect evidence of Ye Luolan's crime. During the investigation, Sang Yuzhi gradually fell in love with Xiao Jingyu. He stood up for her many times in danger. In the end, the two teamed up to expose Ye Luolan's crimes. His conspiracy to collude with the enemy was exposed, and he pleaded guilty.
Sang Ce learned the truth and felt filled with regret. Sang Yuzhi cleared his mother's grievances and took revenge. After the dust settled, Xiao Jingyu married Sang Yuzhi as the regent princess, and the two started a new life together.
