Just like a mobile phone, the communication treasure pearl of the magic world is also very sensitive to distance.
A mobile phone cannot make calls in places without a signal.
The communication treasure pearl in the magic world does not have transmission relays like base stations or satellites, so it can only rely on the magic energy of the pearl itself, making it even more sensitive to distance.
This means that the communication treasure pearl is actually more like a walkie-talkie.
Of course, the communication treasure pearls made by the Elf Clan can actually cover a very long distance, up to hundreds of kilometers without issue.
If the communication distance of a communication treasure pearl is exceeded, it will not be completely unresponsive, but will give a signal via a flash of light.
