New Plan in the Middle Sky World

In fact, these Teleportation Formations served as markers at this time

And if Three Stars Empresses wanted to return to the Blue Star, they would definitely return to the vicinity of this Teleportation Formations. When they passed there, they would encounter the Teleportation Formations arranged by Yang Song.

Therefore, if Yang Song lost his connection with the Teleportation Formations in that abyss, it proved that Three Stars Empresses had returned here!

Therefore, the Teleportation Formations also played a "monitoring" role.
