Dong Tianyu, who was returning through the subway network, didn't expect that Li Minghao had specifically assigned someone to wait for him at the entrance of the underground shelter leading to the surface.
Although the subway network was spread under Pengcheng like a spider web, this path was not as freely accessible as the small roads on the surface.
The subway network was not only patrolled continuously, but anyone wanting to enter any underground shelter through the subway network still needed to go through entry and exit procedures.
Under normal circumstances, you would have to obtain an admission certificate from the originating shelter, which is similar to buying a ticket under real-name system, but this ticket doesn't cost money.
