As a cautious person, Ling Lan didn't go near the bead.
"Little Four, what is that?"
She had no qualms about calling Little Four out whenever she liked. She had went passed the period of feeling guilty for using child labor. After all, she had been looking after him for over 20 years now. Her kindness had disappeared under the guidance of Number Five. Ling Lan was not a good person anymore. Of course, she was not an evil person too.
The more powerful Ling Lan became, the more information Little Four could gather. Hence, Little Four didn't need signals to read data anymore.
"Huh? That is a miniature optical supercomputer. It was made using the same materials as your communicator. It is a communication bead." Little Four did some simple research and managed to find out what the bead was.
