Even Kanglia and Kinglei didn't know who the guy was. Because of Rean's Body Transformation Skill, Roan had a completely different appearance to Rean. Of course, Rean didn't want to get any misunderstandings, so he sent everyone a Divine Sense Message. 'Don't worry, he is here to help. That's a friend of mine who is traveling with me. I let him inside my Pocket Dimensional Realm.'
Still, Kanglia, Kinglei, and all the other experts didn't even see him appearing. Usually, when something comes out of the Pocket Dimensional Realm, there is an oscillation in space around the area where it will appear. That oscillation was pretty obvious and prevented anyone from being taken by surprise because of experts inside someone's Dimensional Realms. However, no one noticed when Roan came outside of the Soul Gem Dimensional Realm.
