Bai Yun spent three days setting up the various formations needed for trapping the entire group. During these days no one left their rooms. They were trying to consolidate the improvements they had gained in the past few days and improve their strengths as much as possible.
Ao Tianzi was also busy at work building the key to trigger the Killing Fields of Ga'Mon. As long as all parties agreed, it was possible to activate it with a simple thought at the God step. But at their current cultivation, they needed a formation for it. Not only that, the difficulty increased since he also needed to pull the guard leader into it without his permission.
It took them three days to finish their preparations. Once they were done with it, they still had a little bit more to decide. Namely where the fight was going to take place.
The ideal place for the battle would be on the shores of the sand lake. There they would be guaranteed that there would be no interference.
