Red and Gulan didn't expect to hear those words so soon. However, they controlled their emotions as they knew they were hiding here. Instead, Red simply used a small voice to answer Kentucky's question, saying, "Kentucky, is that you? Come to the thirteenth rock near the bottom left side. You will enter the range of my concealment skill if you do so."
Kentucky was happy to hear that and immediately did as Red told him. Of course, he was also prepared to escape at any moment, in case it was actually a trap.
In any case, Kentucky got close enough where he could finally see and sense Red. As one must remember, Red's concealment skill was unlike Rean's. Nevertheless, it was very good for this situation as well. Kentucky then spread out his Spiritual Energy around Red, blocking any sound from going out as he exclaimed in surprise, "Red! It's really you! Oh! Gulan is here as well!"
