Tang Mo left the Military Intelligence Bureau due to a misunderstanding and was recruited as an agent by a mysterious organization. In the early days when manpower was scarce and targets were unclear, he formed a temporary team with hacker Vera and heavy soldier Alexey, and got involved in the world's most mysterious criminal network, the "Mirror Project." They run into each other in missions that coexist with humor and crisis, and unlock friendship, growth and faith in the foggy world of espionage. The first volume reveals the establishment and preliminary trials of the team. The second volume goes deep into multiple countries to perform missions. The life experiences of the three people and the identities of the double agents are gradually revealed. The conflict in the third volume escalates comprehensively. All story lines converge and face the overall conspiracy and human choices. It is a humorous collage with a tight rhythm, including agent-style action and reasoning, as well as trivial life matters and light-hearted interludes.
