The senior scholars of the Grand Natural Sciences Academy soon discovered that the Crystal Ball could communicate remotely across academies.
Of course, this so-called remote communication was only remote compared to the Crystal Ball's former communication range.
Only then did people recall that.
The Crystal Ball communication technology had already existed for several thousand years.
In the beginning, the technology had merely been an accidental discovery by a wealthy nobleman who enjoyed collecting crystals. He happened to discover that the Crystal Ball could amplify his Mental Power waves, and after processing them according to specific signal frequencies, he developed a Crystal Ball capable of short-range regional communication between two crystals.
This accidental discovery made during an idle pastime quickly became popular among the nobility.
Although the Crystal Ball's communication range at that time extended only a few hundred meters at most and had almost no practical value, academic discoveries back then were themselves merely entertainment for the nobility. Thus, the Crystal Ball soon became wildly popular among them.
After that came the development of the Energy Source five hundred years ago.
Aside from providing a sufficient and stable energy supply for the High Tower's enormous restriction barrier and protecting the miniature wind eye, the first-generation Energy Source also had an invisible function: the radiation magnetic field could amplify Crystal Ball signals a second time!
From then on.
Regional signal communications were established within the various academies, the primary gathering places of scholars.
At that time, the Crystal Ball had practically become an essential Magic Prop that everyone owned.
After hundreds of years of subtle influence, people had grown accustomed to the Crystal Ball communicating only within the radiation magnetic fields of the Energy Sources at the various academies. In the wild, its communication range extended only a few hundred or
