Shen Qingci, a master of law in the 21st century, traveled to the Zhenguan period of the Tang Dynasty in an accident. When she woke up, she found that she was Shen Wan, the daughter of a criminal who was involved in a fraud case in the examination room, and was about to be taken to the execution ground for questioning.
At the critical moment of life and death, she relied on her extraordinary courage and rigorous logical thinking to "claim injustice before execution" on the execution ground and defended herself in accordance with the laws of the Tang Dynasty, which attracted the attention of the executioner. The case was sent back to Dali Temple for retrial. She analyzed the case in detail and made progress step by step in the courtroom. Not only did she clear her father's grievances, but she also shocked everyone present - including the cold-faced young minister sitting in the corner.
When Emperor Taizong heard about this, he made an exception and kept her in Dali Temple, becoming the first female official in the history of the Tang Dynasty.
In Dali Temple, she met Pei Yanzhi, the Shaoqing of Dali Temple. He was born in the Pei family of Hedong. He was a Jinshi at the age of eighteen and was promoted to Shaoqing at the age of twenty-five. He handled cases with an unselfish face and was known as the "Iron-faced Judge". He is cold and taciturn and never shows any favoritism. He is the sharpest knife in Dali Temple.
Shen Qingci started from the most basic process of sorting out case files, and relied on his solid foundation in modern legal education and a way of thinking beyond the times to demonstrate his talents step by step. She was chosen as Pei Yanzhi's assistant, and the two worked together to solve difficult cases one after another: the murder of the cloth merchant, the murder of Fang Zheng, the poisoning of Wanfuji's boss... Every case solved was a collision and fusion of modern legal concepts and the judicial practice of the Tang Dynasty.
However, as the investigation deepens, a shocking conspiracy involving the remnants of the previous dynasty gradually emerges. Shen Qingci discovered that his father's injustice was not an isolated incident, but a huge plan.
