Aside from being an identity medallion, it also has various other uses such as storing information or sending messages to persons several Kilometers away.
After Xi Shen tapped the medallion, it began to release a soft glow before a white circular rune started to form above it and then slowly began to rotate.
Yang Su who was nervously shifting from one foot to the other looked at the intimidating bodyguards before he turn to Xi Shen and said, “It’s alright young master Shen, I don’t mind staying out here.”
Instead of his usual address for Xi Shen, Yang Su decided to call him young master in front of others. He had concluded that when he was alone with Xi Shen he would address him as elder brother, and when in public he’d address him formally. Even though Xi Shen didn’t mind being called elder brother, Yang Su still thought that the assistant of the second prince of the Maple Continent calling addressing him as elder brother in front of people would be too inappropriate.
