Zhou Ning didn't pause, but continued to speak:
"Although Zhang Yinan's fall wasn't perfectly staged, the follow-up work must have been very thorough. They compensated Huang Li Ming for his car, quickly diverted the police's attention, steered the case towards a narrative of romance and suicide, and even had Cui Haibin forge the lab reports.
Such a multi-faceted cover-up couldn't have been pulled off by the killer alone. And as I said, the killer's counter-surveillance and trace removal skills are comparable to a professional's—like someone who's been specially trained in various areas, skilled in combat, capable of coercion, ruthless in action, and decisive."
Liu Yongxin crossed his arms and stared into Zhou Ning's eyes.
"The more you talk, the more the murderer sounds like a SWAT member, hitman, mercenary, or someone with a similar background, doesn't he?"
