An hour later, Wang Zhong had the map staff gather around the old man, holding the map and asking about the surrounding grassland terrain piece by piece according to the map's numbering.
Military maps are divided into coordinate grids, each with its own number, and there are even smaller grids underneath.
In this way, when necessary, countless maps can be pieced together into one large map according to their numbers.
The old man was, after all, aged and had no idea what the numbers meant, so the maps had to be pieced together like a puzzle before he could "identify" each location.
Fortunately, the command post was now in a barn, with plenty of space for the staff to assemble the puzzle.
Wang Zhong stood by, unable to get involved as he was not as savvy in military cartography as the staff. He was just an enthusiast—how could he understand how to piece together maps?
After about half an hour, the command post's guard brought in the old man's son.
