After the AI escalated the Shi Ziqiang case to a "suspected Secret Realm smuggling" risk level, investigative resources and authority also rose significantly.
The surveillance system soon discovered that the destination of the minibus was not the laundry as assumed, but that it had changed its license plate and continued on the road.
Following normal reasoning, Shi Ziqiang didn't need to pick up people this way, he could have easily arranged a meeting in one place, or agreed to meet directly around the target Secret Realm.
But he insisted on driving himself to collect the groups, put nicely this was counter-surveillance, bluntly it was just making an unnecessary fuss.
However, this tactic did indeed successfully disgust the head investigator Daylight, forcing her to drive around for nearly an hour before she could barely make progress to this point.
