[Spy War + Material Trading + Global Game + Top-notch Cool Articles]
Agent Chen Yang, who has multiple identities, was ordered to lurk in the Japanese and puppet agencies to provide assistance to China's anti-war cause.
In order to lurk better, Chen Yang used material transactions to weave a large network. Even if he traded openly with various forces, no one would think there was a problem with him.
Military Commander: "Chen Yang is our undercover agent."
Japanese Army: "Oh, a clumsy alienation plan."
Red Fang: "Chen Yang is actually one of ours?"
Japanese Navy: "Chen Sang, do you have any grievances that you can't say, it doesn't matter. Yes, tell me. We can make the decision for you."
Chen Yang: "Please, don't just put a piece of yellow clothes on me. You guessed it right, I am really an undercover agent."
