How did all of this happen? To understand that, we need to go back a few hours prior to Rifindio's sudden appearance at the Teleport Building.
Rean and the others had just arrived, and making use of the fact no one expected anything to happen, they made a move on two guards patrolling the city. Those targets were selected carefully, both of them having exactly the same cultivation as Rean and Roan.
Well, the twins were actually in the Sky Space Bending Realm, but others couldn't tell it was different from the normal Space Bending Realm. It was necessary for the targets to have similar cultivations, as the Natural Spatial Perception wouldn't allow the twins to approach the Camazotz Bats without others noticing.
