The vortex causes no harm to those who enter. After entering it, they would be teleported to the Outer Spatial Void outside.
In front of the exit to the Land of Immortal Remnants, there was another gate. Two Cultivators were positioned on either side of this gate.
Above this gate hung an item similar to a bronze mirror, which Lin Jing knew to be a Daoist Treasure that could detect Immortal Yuan. Anyone leaving or entering the Land of Immortal Remnants had to pass through this gate to move freely.
Otherwise, upon reaching the exit's right side, the Cultivators stationed on several huge meteorites would appear.
Guarding this gate were just two early Mahayana Cultivators responsible only for maintaining alertness. They weren't in charge if any unexpected events occurred.
