The serial killer ghost that keeps committing crimes is very cunning. It must have sensed the crisis and managed to slip away several times during ambushes, going silent temporarily without causing any more murders.
This forced Huang Yaozu and the rookies from the miscellaneous department to start from scratch.
They used conventional investigation clues to find patterns, tracking the last known locations of the fierce ghost, and then went through the crowds to conduct one-on-one inspections.
This led to a massive increase in their workload, making progress slow, and they could only follow the fierce ghost's trail.
However, Zhou Xingxing, who had initially doubted the miscellaneous department, was the most committed to this operation to make up for his previous mistake, even more so than Chen Jiaju.
He even went undercover with Cao Dahua in a high school that the suspect seemed to frequent.
