Outside an area of one li, space remained normal, but within that one li, it ceaselessly compressed and expanded.
Viewed from a macro perspective, this one li of land was a world unto itself, a world of swords.
If a Spirit Transformation cultivator unsuspectingly stepped into it, they would find during their passage that the distance inside was far more than a mere li. It was a hundred li, even a thousand li.
The Void Sword World.
This was the sword world Han Yi created by applying the Space Rule within the Void Sword World.
Once he replaced the nine Half-Immortal Items with nine true Immortal Swords and further advanced the Space Rule, then found a Boundary Stone, he would stand a chance of briefly creating a small world.
Withdrawing his spread-out Divine Consciousness, he collected the Nine Swords with a wave of his hand, and the Void Sword World vanished in an instant.
Then, he reactivated the Returning Ruins Sword Array.
