Secret Brother - Memoirs of an Agent

My name is Chu Xian. I have been rebellious since I was very young. I quarreled with my father and joined the army out of anger. At that time, it was not for the purpose of being loyal to the motherland. I just wanted to find a stable job after retiring from the army. Later, I joined the special forces inexplicably. I only wanted to finish the training quickly and get a good job. However, I entered an extremely secret department with four brothers - the Ministry of National Security... Based on the needs of tasks and knowledge, the five of us brothers created fake identities and college entrance examination scores and were assigned to a well-known university. In fact, there is a more mysterious criminal organization hidden behind the university, and behind the criminal organization is an unpredictable "relevant department"... For my brothers, I can give my life; but for love, I have lost the qualification to give my life for my brothers...
