Chapter 463: Perfect Calculations

Let's rewind time a bit.

On another side.

Just as Shannu appeared in front of Wang Hong Dao.

Gu Qing Shan brought Qing Rou and Wan Er to the lowest layer of the floating island.

Every formation that kept Guang Yang sect running was here.

"Being able to cover an entire island always required large-scaled formations" Qing Rou told him.

"Under normal circumstances, at least three formation users are needed to control such a large formation" Wan Er added.

Gu Qing Shan nodded and stared at the layers upon layers of large-scaled formations.

His gaze became stern.

"We're lucky that we're on the inside of the defensive formation, otherwise breaking in from outside would've been a nightmare" Gu Qing Shan commented.

The formations of this world were simply too powerful.

Formations here were frequently layered upon one another, and to further increase efficiency, every single one of them were layered in the dozens.
