Chen Xiaobei could have used his primordial spirit realm to eavesdrop on their conversation even if they were separated by a wall.
However, Xu chengshou was an existence at the level of the Deputy sect master of Tianji city. If he used his primordial spirit domain to eavesdrop, he might discover it.
If he acted rashly and alerted the enemy, Chen Xiaobei would not be able to get the information he wanted!
"Whoosh ..."
Chen Xiaobei then activated the divine ear charm!
The divine ear talisman was a divine talisman made from the clairaudient. Within a certain range, Chen Xiaobei could hear anything he wanted to hear!
Moreover, the divine ear charm was at the divine immortal level. Even if a peak earth level deity used their primordial spirit realm to interfere, it would not stop Chen Xiaobei from eavesdropping!
With this talisman, Chen Xiaobei could hear everything he wanted to hear!
"Greetings, President Xu!"
