I Was Engaged in Espionage in the Republic of China? Sir, I Beg You to Join Us!

Zhou Shanquan accidentally slipped into the military academy of the 1930s. As soon as you opened your eyes, you were pulled into the Military Intelligence Agency? Military Intelligence is great, no need to go to the front line! But... Zhou Shan can't escape the battle between the two departments! When he encountered the red lurker, Zhou Shan was all numb! But he didn't expect that maybe because his disguise skills were better, the other party didn't see through him? From then on, Zhou Shanquan began to wander among the three parties. Who says he can't do it? With the help of the system, it is only a matter of time before he leads the three parties! Although the Republic of China was in troubled times, becoming a spy king was easy for Zhou Shanquan!
