The only person who could represent the black mountain crystal and was inseparable from it was the Young Emperor --Prince Yan. All the Yan Immortals and even the top cultivators in the Heavenly Region under Zhen Wuyang knew about this.
Right now, in the Northern Heaven Celestial Prefecture, there were several stalls selling black mountain crystals, which seemed to be some kind of subconscious promotion.
Jian Wushuang could vaguely feel the undercurrent under the calm lake.
"This time, I'm afraid we'll have to be even more secretive about our whereabouts. Let's temporarily delay our approach to Prince Mo," Jian Wushuang said in a low voice.
Chun Qiu shot a glance at the young cultivator who was packing up and leaving, "Did something happen?"
He shook his head and said, "We unknown the current situation. Let's follow him and find out what's going on."
