Ling Yunfeng, the captain of modern Jinling criminal investigation, is proficient in trace investigation and criminal psychology. While chasing the murderer Ouyang Shuo, they both fell into a sinkhole. Their souls traveled to the fifteenth year of Hongwu and became a trainee captain of the Jinyi Guard at the bottom of Yingtian Mansion. Relying on modern criminal investigation techniques and his familiarity with the history of the early Ming Dynasty, he solved many unsolved cases one after another. Many of the methods of committing crimes bear Ouyang Shuo's unique criminal characteristics, and all clues ultimately point to the current prince-in-law. At this time, the court was in turmoil, the remnants of the Hu Party were not cleared up, and the root cause of the Lan Yu case was buried. While Ling Yunfeng was steadily promoted, he carefully dealt with Zhu Yuanzhang and other nobles, while secretly collecting evidence and secretly competing with his time-traveling enemies who held high positions and held resources. In the Hongwu court, where the law was strict, a battle between good and evil that spanned time and space began.
