Lu Chengzhou approached her and asked, "You're done investigating?"
Gu Mang looked at him through the corner of her eyes and hummed a "mm" in response.
Department Chief Yan returned to his senses and smiled. "Thanks a lot for your help, Ms. Gu. The higher-ups are pressing us on this case and it's good to finally see a development."
Who would think that someone would use acupuncture to kill in this day and age?
Gu Mang nodded. "If there's nothing else, I'll leave first. There is still homework to do."
The corners of Department Chief Yan's lips twitched when she said 'homework." Right, this big boss was still a high schooler.
Lu Shangjin tugged at his suit. "Then I'll head back first too."
Department Chief snapped back to reality and said hurriedly, "Sure, let me see you and Ms. Gu out."
They left the police station.
