The lead provided by the whistleblower was cut off there and there was no further information to be gleaned. Wu Min and the others stood up to bid farewell to Zhang Ziwen, and as a matter of routine, they admonished him, saying things like he must cooperate with the police to capture the fugitive, and not to protect the guilty, and so on. Zhang Ziwen's performance was spot-on, repeatedly ensuring that he would fulfill his duties as a law-abiding citizen and would betray kin for justice, speaking the words with great fluency.
As they were about to leave, Wu Min's pace slowed down a little. Just as Ouyang Zheng stepped out of the office, she turned back and whispered swiftly and softly to Zhang Ziwen who was following behind her, "Meet me tonight at 9 at the usual place."
Wu Min's voice was very soft, her cheeks flushed. As soon as her words fell, she quickened her pace to catch up with Ouyang Zheng.
