The vehicles headed south, and occasionally small stone monuments with inscriptions like "18, 223," "18, 224," appeared along the roadside.

As the sun began to set in the west, Qin Cheng suddenly said over the walkie-talkie, "It's getting late. We will soon reach the iron net entrance, get ready to camp."
In the back of the truck, Qin Yiyi and Qin Tong started packing things up.
