After carefully discerning with concentration,
Ronald finally made out what was on the screen.
— It was a map.
Outlined by contour lines were the topographical changes in elevation surrounding the area; the coastline also had rather exquisite contours, and right by the sea, the city's buildings were marked out in checkered blocks.
Ronald fell silent.
Faced with such a situation, he was somewhat undecided.
This kind of spell that could transform objects into maps was relatively easy to guess.
To put it recently, there were classic maps, like Yu's Map or Map of the World, that could serve as references.
However, considering the contour lines, it was more likely to be a river map adopting the method of depth lines or Dupont's contour maps.
But then...
That made things even more complicated to explain.
Ronald was already quite familiar with the power of the original texts, the magical capabilities of these books in their respective fields were naturally beyond doubt.
