Liu Dayong, a criminal police captain in the 21st century, was reborn as a fifteen-year-old boy from Bingzhou in the Tang Dynasty. What's outrageous is that the owner of his body is named Di Renjie - yes, the same Di Renjie in history. He is also bound to a tsundere system, which can analyze clues, scan evidence, and accurately destroy trouble when he is acting cool while handling a case. From the small town of Bingzhou to the sacred capital of Luoyang, as the recorder of Dali Temple, he opened the door to the undercurrent of imperial power.
Six volumes, more than 60 cases: theft of Buddhist scriptures, the poisoning of the prince, fraud in the imperial examination, the seizure of the heir by the king of Wei, smuggling by the Snake Gang, the intelligence empire of Tianshu Pavilion, the infiltration of the Japanese country... Under each layer of truth is a deeper abyss. But his biggest enemy is not the murderer, but himself - is he Liu Dayong or Di Renjie? When the modern rule of law collided with the power rules of the Tang Dynasty, he chose the only way: not to take sides, not to speculate, but to respect the law. Surrounded by the tough-talking and soft-hearted senior sister Shen Yunyi who gave bricks as gifts, the cute and kind-hearted drugstore girl Su Banxia who stuffed three times the medicine bag, and a system responsible for precise troubleshooting.
However, a scar-faced man called him "Huaiying" with guilt hidden in his eyes; the letter from the master of Tianshu Pavilion claimed to be "my nephew", which was paraphrased as "an old friend of your father's and owes your father a life"; his mother Cui hesitated to speak... The system gave a judgment - your father Di Zhisun hides a secret directly related to the reason for your time travel. He always thought he was playing Dee Renjie. But maybe, he is Di Renjie. That time travel was never an accident.
