"...That's pretty much it,"
Han Rui explained in detail to Wang Tao about the "contact method" and its origins.
In short, they had encountered a small squad of soldiers on the road previously, but only three members of the squad were left, all severely wounded and beyond saving. Before they died, they told Wei Zhenguo about a way to contact a base and urged them to go there.
The reason this contact method was believed to be authentic is that the squad had established contact with the other party before, but unfortunately, they didn't make it to...
As for the specific operation of this contact method, it required the use of military base equipment and some underground cables for communication.
But having these things doesn't mean one could make contact right away; it also called for various equipment adjustments and the input of a secret key, which was very complicated.
Of course, the most important thing was that the equipment and lines were not damaged!
