Although the queue for entering the city at the gate was somewhat long, based on Dong Tianyu's observations of the pace at which the line moved, the entry inspection process should not be complicated, otherwise the movement of the queue would not be so swift.
After the three of them reached the end of the line and started queuing, it further confirmed Dong Tianyu's earlier speculation.
It took less than a daytime for the Thompson family of three to have their turn for the city entry inspection, which was very simple. A dedicated instrument was waved around each person's throat, and as long as the instrument showed green, then the person could easily pass through.
When the machine displayed a red light, the nearby government officials would immediately take action, subdue the person being inspected, and after securing and binding them without delay, they would take the subdued person away.
