C512 Karakorum Polaris Bridge
Heavenly bridge.
Although it had the name "bridge", it was actually a large scale teleportation spell that was placed on top of the Immortal Realm Plaza in Karakorum. Once his Kunlun Sect Members had reached the foot of Mount Kunlun, he would be able to establish a connection with this legendary magic, allowing him to reach the Kunlun Immortal Realm in the blink of an eye
