In the early days of the founding of the People's Republic of China, the world was in chaos, and car bandits and road bullies were rampant. A modern white-collar worker traveled through time and became Li Yuemin, an orphan from Nanluoguxiang. He joined the security department of a steel rolling mill but was cowardly and incompetent and was despised. After being reprimanded by his master and despised by his neighbors, he suddenly woke up, lost his cowardice, took the power of his post, and carved a way out in the turbulent era.
