In the Daqian Dynasty, official administration was corrupt and there were many unsolved cases. The humble county government official was responsible for the case of Gu Chang. During an autopsy, he was accidentally involved in a strange case of killing an official. When he was about to die, he activated the "Qingtian Simulation System". This system can transform any case he faces into a "copy world" that can be entered, deduced and simulated unlimited times. In the simulated copy, he can recreate the incident, talk to the virtual deceased and the suspect, and discover the secrets of the crime that were ignored in reality. By solving the case perfectly in the copy, he acquires various god-level skills (micro-expression insight, scene reconstruction, official speaking skills), and accumulates official ranking points, rising step by step. When he graduated from the county As the government went to the capital city and then to Dali Temple in the capital, he found that all seemingly independent cases pointed to a huge conspiracy that could subvert the entire dynasty. He must use the simulation system as his biggest trump card in the treacherous officialdom to find out the mastermind behind the scenes and become the minister of salvation holding a sword in one hand and a seal in the other.
