This object was made based on the Tier Zero Magic, Communication Skill, and is an alchemy level magical item that can transmit messages remotely within a straight-line distance of less than one hundred kilometers.
Moreover, it doesn't require Spiritual Power to activate, making it very convenient to use.
Sunan specifically made several of these, and gave one to Kei in addition to Sherman and the others, for contact in case of emergencies.
After activating the communication crystal, Kei's voice quickly came through.
"Sunan?"
"Is there any situation on your end?"
Kei was stunned for a moment, seemingly puzzled, and then said, "No, you ask because..."
The sentence was interrupted as if by something, and it took a while before the voice came through again.
"Someone has invaded!"
Indeed!
Sunan's gaze turned cold, and he said gravely, "I'm coming over now, be careful."
As he finished speaking, he leaped, and Hidden Dragon appeared out of nowhere below, catching him just in time.
