After Alister activated the Dimensional Mirror, it connected to the other copies of the dimensional mirror.
It activated the video call function and like the modern smartphone, Alister and the leaders of the major race alliance were having a video call.
However, it was a technology far superior to the modern smartphone.
The dimensional mirror displayed a holographic screen that imitated the system's screen. However, unlike the system screen with the system menu and other functions, what was displayed by the dimensional mirror's holographic screen was none other than the faces of the leaders of the major race alliance.
Or to be more specific, it showed the location or scene that was reflected by the dimensional mirror copies.
When Alister had activated the Dimensional Mirror, it also alerted the holders of the dimensional mirror which was similar to a call ring tone.
