At the station, local authorities escorted Lu Jiansen and Gu Xiaoxi to a secure government guesthouse.
A senior official named Director Hao walked into the reception lounge, catching sight of Gu Xiaoxi and smiling warmly. “You must be Xiaoxi! I haven’t seen you since you were little—I used to live next door to your grandfather’s house in Huai City!”
Gu Xiaoxi recognized his familiar face. “Director Hao!”
“Jiansen brought the report to our attention,” Director Hao said, leaning forward. “Tell me, Xiaoxi, how did you catch onto those two individuals on the platform?”
Gu Xiaoxi explained how she noticed the man discarding a pristine cigarette box and the woman stealthily retrieving it minutes later.
Director Hao nodded in approval. “Information couriers often use innocent-looking trash swaps to pass intelligence. Your sharp observation saved us weeks of investigation!”
Using her description, security officers apprehended the courier network at the station, recovering concealed document film hidden inside the hollowed lining of the cigarette container.
