Inverse Spirit Channel

A temporary spatial channel forcibly opened from the Spirit Realm to the Mortal Realm (or vice versa) using immense power and top-grade spirit stones. It is not a fixed, physical location. It was used during the ancient war to send reinforcements to the Mortal Realm. Re-opening it requires significant cost and coordination from the Spirit Realm side (e.g., using a Boundary Crossing Incense to signal). Special individuals like Linglong can have a personal ‘Inverse Star Plate Mark’ that allows a small, personalized channel to be opened for their return.
