Guarding The City 

A few moments later, Chen Chen expiated the fourth prince of Great Jing with the Haoran Sacred Light Method and the level of his divine senses had also increased. It seemed to have reached a bottleneck, and if he continued to break through again, he would very likely reach the Void Refinement realm.

Rumor has it that divine senses of the Void Refinement realm were much stronger than that of the Essence Soul realm, though it was unclear whether it was true or not. 

Anyway, Chen Chen could ascertain that the masters of the four major human clans could search within a 500-meter radius using their divine senses. 

...

They returned to the Demon Suppressing Town to see that the Human Extermination Mountain had already retreated by 500 meters. 

Now, the power in the Demon Suppressing Town was far from what the demons in the Human Extermination Mountain could compare to, so the Human Extermination Mountain can only retreat.
