Lu Ze and the girls went downstairs with Louisa and found that there was no one in the foyer.
Lu Ze guessed that they might have learned something from the phenomena. After all, they were the most talented bunch in the East Region.
Louisa smiled and said, "I'll send you off here."
She took out something. "Here, Lu Ze, take this."
She gave out a few small devices to Lu Ze's group.
Lu Ze took the instrument and asked with some doubts, "What is this?"
Louisa explained. "Communicator. It can be used in the Elf Cosmic Realm and nearby cosmic realms. My contact details are inside, if there's anything, contact me."
Lu Ze and the girls rejoiced.
The Human Race's communicators can only be used near the Milky Way. The Elf Cosmic Realm was over hundreds of millions of light-years.
If they went out, it would be very hard for the elders to contact them.
This was rather convenient.
