"What was going on?"
Even An Jing was somewhat surprised at this moment. He could not understand why the Tianyuan Realm had suddenly begun to move.
[This situation...] Several Old Ancestors of the Mingjing Sect were also uncertain and alarmed. None of them had ever left Huaixu, so naturally they knew nothing of worlds shifting through Taixu.
Only the Haotian Mirror was inwardly startled. [Could it be...]
[Is it Tianyu Migration?!]
Movement within Taixu differed from that in the material world. In essence, there was no distance in Taixu; transmission between places relied on the "links of karma."
The more entangled the karma between two worlds, the more exchanges between them resembled those of the material world. Take the Northern Heaven Grotto-Heaven and the Tianyuan Realm, for example—their interweaving was practically identical to that of a real material world, and they had even developed the concept of "distance." This meant that, without intervention, the two would soon merge and fuse into a single realm.
But if there was no karma between them, then the two worlds would never interact.
Unless cultivators from one world left their homeland and arrived in another.
Or unless cultivators from both worlds left their homelands, met in a third world, and exchanged information about their respective native worlds.
In that case, the unseen threads of karma would turn into bridges and [roads], connecting the two realms. Only then could they establish a cross-realm Gate of Taixu founded upon karma.
If trade between the two realms grew ever more prosperous, then through the exchange of karma, the two worlds could even draw conceptually closer and closer, until Taixu transmission eventually became incomparably convenient.
Of course, that was only theory. In practice, given the scale of human commerce, even if one sold everything in an entire world
