Why did the Japanese know so quickly?

Is it possible that besides military agents, there are also Japanese people who are monitoring their own spies?

"You must make an explanation." Takeshi Okamura said coldly: "I'm waiting for your report!"

...

One hour ago.

"Chief of Okamura? Don't worry about who I am, I will report to you. Bo Jun, deputy chief of the Intelligence Analysis Section of No. 76, is a hidden agent of the Military Commission. He defected with a large amount of top-secret intelligence, including Qingxiang troops.

Yes, the information is absolutely reliable, and Li Shiqun is likely to find ways to cover up this matter."

Bojun said and hung up the phone.

Zhao Yun smiled.

Who would have thought that a "defector" of No. 76 would take the initiative to inform the Japanese?

"Okay, my mission is completed."

Bojun smiled and said, "The moon was bright in the Qin Dynasty and the Han Dynasty was passive. People had not returned from the Long March. But the flying general in Longcheng was there and did not teach Hu horses to cross Yinshan. "Longcheng" completed the task and requested to return to the team!"

"We will escort you out of Shanghai and Chongqing as soon as possible, and there is a new job waiting for you."

Zhao Yun shook his hand: "Thank you for your hard work, brother."

It was not until now that he knew who "Dragon City" was.

Who are the other brothers in the "Wang Changling Group"?

How many of my own comrades are lurking on No. 76?

I'm afraid only the superiors know all this.
