Help that can't help

The location Roan was talking about was something Rean had prepared in advance. Together with a few of the sect's Formation Masters, Rean traveled into some concealed places near the battlefield and built several teleport formations before hiding them with a concealing formation. 

When they arrived there and Rean revealed the teleports, they all saw twenty big teleport formations positioned close to each other. "This... how did you do all of this without me noticing?" Himisve couldn't help but ask.

"Hahaha!" Rean laughed in response, telling him, "First of all, this is a place that no one would use to attack. It's too narrow and easy to be ambushed in. With that being said, you probably never sent more than a few Nascent Soul Realm cultivators, demon beasts, and spirits to take a look here. Such low-level beings would never be able to see through my concealing formation."
