Xiahou Kun had long known the origins of the two, and at this time, he followed up by saying, "The two friends have shone brightly on the battlefield of Accumulation Thunder Mountain, I have long heard of this. Now that we have met, it truly feels like a regretful delay!"
True Disciple Qin glanced at him and then turned to look at Zheng Kejian.
"Where is Elder Brother Zheng Xian?"
Zheng Kejian cautiously said, "My uncle is in closed-door cultivation, striking toward the Great Circle of Foundation Period."
Song Fengzi, who was at the side, showed a pensive expression upon hearing this.
The breath he had previously sensed, nearing the Great Circle of Foundation Period, seemed to be that of Zheng Xian, mentioned by the two of them.
