In Shen Mo's understanding, a world possessed two forms of existence at once; therefore, there were also two ways to travel to another world!
The first was to escape beyond the Nine Heavens and search for other worlds amid the vast, boundless void of the cosmos.
But how immense was the cosmic void? Forget finding a world that had given birth to living beings—even a speck of meteor dust was difficult to find. This method was like fishing a fine needle out of the Sea of Buried Immortals... Even a powerhouse of the Formless Realm, provided they had no shortage of spiritual resources to replenish their mana and maintained their fastest escape speed, might not find a single world before their lifespan ran out.
The second was for Divine Bridge Realm cultivators to refine a Forbidden Land, or for beings of the Formless Realm and above to rely on their own Dao cultivation to sense the existence of other worlds in the unseen and forcibly descend upon them.
This method was not constrained by concepts such as direction or distance. It was an immortal technique that crossed dimensions, unfathomably miraculous!
Inside and outside, the land of Evil Spirits was only the size of the Left Li Kingdom's territory, far smaller than a normal world. Yet whether one fled toward the four cardinal directions or beyond the Nine Heavens, one could not fly out of this place. It was a strange land that formed a world of its own, yet possessed no spatial barrier.
But if they attempted the second method and forcibly descended into another world, they might perhaps break free of its shackles and escape this bizarre realm!
As for why Shen Mo's group did not personally refine a Forbidden Land and attempt to leave...
The reason was simple.
