"During the initial establishment of Xinjie City, each agency had very few inside agents, and they had to maximize their effectiveness. Therefore, the probability of placing two moles beside Director Tang at the same time is too small."
Upon hearing this, Liu Fuping was startled and suddenly realized that Qiu Tu indeed seemed to have logically and methodically eliminated all the distracting options.
But she still felt somewhat unconvinced.
She asked, "Then why do you guess that I am a mole sent by the Eastern City Investigation Bureau?"
Qiu Tu smiled.
"It's quite simple. You are not a mole for the Anti-government Armed Forces, so you can only be a mole from one of the three major power institutions. And since you are not a mole from the three major power institutions in Xinjie City, you can only be a mole from another city."
"Your interrogation skills are sophisticated, your methods cruel, and you are extremely familiar with the various regulations of the Investigation Bureau."
