Looking at the first map's red dot, Ye Tian's mind wandered.
This red dot must mark an important location, but what does this location represent?
A treasure map? The location of dragon veins? The address of a mass grave?...
— Ye Tian pondered dozens of possibilities, but felt that none of the possibilities he considered were reliable.
Suddenly, a term came to mind!
Earthquake!
If the red dot indicated the epicenter of an earthquake, then the surrounding terrain would change to varying degrees depending on the earthquake's magnitude. The flow direction of rivers, the positions of mountains, and depressions would also change accordingly.
Now that he knew this, Ye Tian naturally became enthusiastic!
Ye Tian pulled out some paper and a pen and began to make calculations on paper. It's worth mentioning that Ye Tian had considerable mathematical ability, so he also dabbled in geographical knowledge.
