Mu Yuan had once heard the story of an undercover agent. That was his first class monitor after he joined the Army. He was talking about an undercover agent from a few years ago. He had never been able to walk out of his undercover life because he had successfully infiltrated the police. The police had caught a huge drug trafficking group in the country, but there was a young man in the drug trafficking group who called him brother.
The young man usually helped transport goods and treated him like a brother. In the last operation, some people from the drug gang were still fleeing, and many people died. The young man also died. Before he died, he kept asking him why he betrayed them. The three-year undercover life was a real person, not a bunch of data or a fake life. The class monitor had never been able to walk out of it.
