Song Guanchao was momentarily taken aback, then showed a hint of surprise.
He was quite unexpected; he didn't expect Liang Jianfeng to have figured it out.
Song Guanchao pondered for a moment, then nodded.
He didn't mention Wen Ru.
Because he had no evidence.
Liang Jianfeng was the director. Even if he could tolerate Song Guanchao using some unofficial methods to investigate, to completely convict, evidence was necessary.
Without evidence, telling him that Wen Ru was the undercover agent would only put him in a dilemma.
Moreover, Wen Ru had deep tactical foresight; this was evident from tonight's setup.
Liang Jianfeng needed evidence to make an arrest, but if Wen Ru was forced into a corner, she wouldn't need anything like evidence; she would act ruthlessly.
"Do you have any suspects?" Liang Jianfeng suddenly asked.
Song Guanchao nodded and then shook his head: "Yes, but I'd better not say, to avoid Mr. Liang from making a misjudgment."
