The map that Yuan Zhou took was not a regular one. On it were the names of many buildings, some high and some low, marked in various colors. Although they were not very dense, there would be conspicuous landmarks after walking for a while. By comparing the two, if he took the wrong route, he could immediately change to another one. At least it was better than walking for a long time without knowing whether he was right or not.
The map specially made by Yin ya was one of Yuan Zhou's necessary magic weapons every time he went out. Of course, Yin ya had never been to Yunzhong before, but that didn't stop her from collecting information from various channels and drawing this fairly detailed map in case Yuan Zhou got lost.
"Little ya's map is easy to see. Every time I look at it, I'm full of confidence in finding the right path."
