This time, the map upgrade was completely different from before.
Because the distances between small worlds were not three-dimensional; instead, they were part of a more complex coordinate system.
However, the small map simplified this coordinate system. In addition to marking the coordinates clearly, it also distinguished the relative distances through the relationships of these coordinates.
This undoubtedly aided Human Civilization in establishing a defense line for the small worlds!
It's important to know that even for Weird Demons, accurately locating the small world where the Human Mother Planet was not an easy task. They only roughly knew the "direction" and had to probe each one by one to find it. With such a defense line in place, one could be alerted to the movements of the Weird Demons immediately and even intercept them directly in these small worlds, greatly reducing the scale of the wars on the homeland.
Shen Hao even spotted a "loophole".
