Traveling through time and becoming a government official in Chang'an City of the Tang Dynasty, Wei Qian just wanted to catch a fish and lie down. Until that day, the Imperial City Si Baiqi sealed off the Western Market and trampled the children to death in the streets. No one dared to control them. Wei Qian stood in front of the horse and shouted: "Stop! According to the laws of the Zhou Dynasty, the horse will trample through the busy city for no reason, the staff will be eighty!" [He activated the urban management law enforcement system] adhere to the ten policies, ignore the powerful, and kill all the princes within their authority! [Since then, the most hard-core urban management in the Tang Dynasty was born] Qiwang, the fifth surname, sells private salt? Search your home! The powerful prime minister is greedy for money and money to repair the canal? Thorough investigation! Human trafficking of women and children? Killed with a cane! No matter what noble prince you are, you must abide by the law within my jurisdiction. The delinquents of the school awaiting inspection, the supervisors of the two cities, Zuojie envoy, Jingzhao Shaoyin... The titles came down one by one. Li Shimin panicked: "Don't let him be promoted again! If he is promoted to the throne again, he will be investigated!"
