Unlike his first attempt at returning, which began instantaneously the way Teleportation usually worked, this time the process was slow and drawn out. A wave of energy spread out slowly, as if a viscous liquid were flowing down a slope.
This was the spatial energy which would form a barrier around them all, and it was slow and weak due to Lex's low cultivation realm. Already, before the teleportation had even begun, Lex needed to tap into the energy reserve of Lotus just to ensure the barrier was completed.
But, then again, the start of the teleportation was also the most expensive in terms of energy consumption, so it made sense.
None of the workers moved, as even though the barrier around them had not formed, they could feel the process had begun, and a heavy weight pressed down on them.
After an exaggerated few minutes, the barrier was complete, and all of them vanished.
