As for the Flame Fire Golden Sand, it sounded related to Flame Fire, but he couldn't even begin to guess its nature. It wasn't just recently; Su Chen had already sent people to secretly investigate for a while, and even purchased clues from the Prophet Council. However, he still found absolutely nothing regarding these two materials.
Su Chen wondered, "What exactly is the mission Old Qing went on? Why hasn't he returned yet?"
Qing Cang had escorted Qin Yun there, and the Ancient Kings had caught up from behind. Logically, Old Qing should have returned long ago. Yet even the Peng King had already come back, but Old Qing was still nowhere to be seen. Su Chen had investigated both openly and secretly before learning that Old Qing seemed to have gone on some mission. If there was anywhere he could get clues about these two materials, it would probably have to be from Old Qing.
Su Chen let his thoughts wander for a while before gradually entering his development state.
