Ganhan was still working with the disciples of the System Sect when he noticed that they all seemed to use their badges every now and then. After asking one of them why they were doing that, the disciple asked the elders of the System Sect about what to do. Rean and Roan had given permission to a few of the System Sect's elders to judge whether the disciples could talk about the communication system or not. Now that the communication system would spread as fast as possible, it went without saying that trying to hide it from Ganhan and the others would be meaningless.
"What?! You can do such a thing?" Ganhan, obviously, was shocked to hear about the communication system. "Can I test it myself?"
The disciple shook his head, telling him, "Only System Sect members have these communication badges. Even if you try to use the badges, they won't work as they only respond to their owner's Divine Sense."
