Mu Qiubai was in a bind. She stood upright, giving the old gentleman a standard military salute, "I apologize, sir. My identity... Mr. Chen said... is not yet to be disclosed, I'm sorry, I cannot tell you."
Ming Mei had to admit that Mu Qiubai was intelligent, otherwise she wouldn't have been able to stay in UC for so many years.
Mu Qiubai knew that the old man was a military personnel, she was very clear that maintaining discipline and obeying orders were of utmost importance to them.
Everyone who comes from the military, particularly their special agents, have strictly enforced confidentiality regulations, they never utter more words than necessary.
And those leaders from the military enjoy having those types of soldiers.
No matter how high your rank is, no matter how you ask, I will not tell you, you see, I respect my job and I would never bring disgrace to the military.
