Siheyuan: Retired from the Army, but a Criminal Master!

He Yufei traveled through the courtyard and found that he had become a soldier who had been in the army for more than ten years and then changed his profession. At the beginning, you directly enter the security department of the steel rolling mill and become the deputy section chief of the security department, with a monthly salary of 68 yuan. But, what the hell is this criminal master system? As long as the criminals get the punishment they deserve, can they gain proficiency in various criminal skills? Dismemberment, counterfeit currency production, tomb robbing, robbery, burglary, gun manufacturing, gambling, and even milling... No, am I really a police officer? With him in the courtyard, paternalism can only be carried out with its tail between its legs. Yi Zhonghai fell from the altar of moral heaven, and Qin Huairu's white lotus image was reversed... In this booming era, He Yufei took off with his unreliable system!
