The twins couldn't tell the number because the Divine Sense Bending Skill only worked if there was a Divine Sense touching it. Although there were a few Divinity Realm Divine Senses spread, those weren't all. The twins only counted eleven.
However, their conversation didn't go unnoticed by Landeau. Since he himself is a Peak Divinity Realm Expert, his Divine Sense obviously had no issue detecting other Divinity Realm experts... as long as they weren't using any treasure to conceal their presence. Nonetheless, even if Landeau's Thirty-Three number isn't correct, it shouldn't be far off.
"Thank you, senior Landeau," Rean bowed to the Essence.
"Hmph!" Landeau just snorted.
Roan looked around, trying to find Kafan. However, Kafan was nowhere to be seen. In fact, he couldn't see Gragatou either. "Where are the Semi-Celestials?"
"No idea," Landeau answered. "They most likely will only show themselves when it is time to enter the Hidden Realm."
