Jinyi! Mountains and Rivers!

Ye Lingfeng, a modern criminal investigation policeman, woke up and became a rich man in late Ming Dynasty. His father died in the battle in Liaodong, the family was heavily in debt, and there were only two years left in the Ming Dynasty. There is no system, no golden fingers, he only has modern criminal investigation knowledge and a lot of history of the late Ming Dynasty. The case of mutilated corpses in Beijing, Shuntian Mansion is helpless. He took the initiative and used modern forensic methods to solve the case in three days, but a bigger secret was involved - the eight major Shanxi merchants, the Duke of Chengguo, and the Houjin outside the customs were all tied by the same chain of interests. His father died because of this. Chongzhen made an exception and promoted him to form the "Plum Blossom Guard". Cao Huachun, the governor of the East Factory, was trying to win over him but was secretly guarding him. Zhu Chunchen, the Duke of Chengguo, held a banquet and threatened to promise huge profits. He only has a few unsuccessful brothers: veterans, demoted soldiers, and disarmed scouts. Until the woman in the moon-white skirt stopped in the corridor of Qianqing Palace and looked back at him. "You did a great job," she said. She is Princess Changping. The Ming Dynasty will not be destroyed, and the Later Jin Dynasty must be destroyed. This is a modern policeman's comeback in the late Ming Dynasty.
