I Asked You to Be a Spy and You Became the Commander-In-Chief of the Empire?

Qi Xiu traveled through time and landed in the escape cabin, squeezing in the real spy. In order not to expose his identity, he could only pick up the real spy's belongings and go to the military academy to report. I thought it was the beginning of hell, but unexpectedly the sign-in system awakened. "On the first day of signing in, you will get: VF-1 Valkyrie fighter jet!" "On the tenth day of signing in, you will get: Macross Macross!" … Years later, the secret communicator finally rang. Boss: "The organization has decided to activate your hidden secret. Remember, concealment comes first!" Qi Xiu: "Understood, I have sneaked into the top management and will never leak any secrets." Boss: "That's good. What's your current position?" Qi Xiu: "It's nothing. They just elected the highest military governor of the empire. Now the whole army is my people. No one will suspect that I am a spy." Boss: "???" Qi Xiu: "Stop talking, I'm going to host my coronation ceremony."
